Q: Trismus is due to spasm of which of the following muscles

Medial pterygoid. ***Medial pterygoid*** - **Trismus** is characterized by persistent spasm of the **muscles of mastication**, leading to difficulty opening the mouth. - The **medial pterygoid** is a strong jaw **closer** muscle, and its spasm contributes significantly to trismus along with other masticatory muscles (masseter and temporalis). - Among the given options, medial pterygoid is the muscle of mastication that causes trismus when in spasm. *Mentalis* - The **mentalis muscle** is primarily involved in **pouting** and elevating the lower lip. - While it affects the lower face, it does not directly control jaw opening or closing to cause trismus. - It is **not a muscle of mastication**. *Lateral pterygoid* - The **lateral pterygoid muscle** is primarily responsible for **depressing** (opening) the jaw and is also involved in protrusion and side-to-side movements. - While it is a muscle of mastication, in the context of trismus (jaw closure spasm), the **medial pterygoid** (jaw closer) is more directly implicated than the lateral pterygoid. *Buccinator* - The **buccinator muscle** forms the muscular wall of the cheek and is involved in **chewing**, whistling, and keeping food between the teeth. - It does not directly control jaw opening or closing, and its spasm would not be the primary cause of trismus. - It is **not a muscle of mastication**.

Q: Adam's apple seen in boys is because of:

Thyroid cartilage. Thyroid cartilage - The "Adam's apple" is a common term for the laryngeal prominence, which is formed by the anterior projection of the thyroid cartilage. - During puberty in males, the thyroid cartilage grows significantly, leading to a more prominent protrusion and deepening of the voice [1]. Tracheal rings - The tracheal rings are C-shaped cartilages that provide structural support to the trachea, preventing its collapse. - They are located inferior to the larynx and are not visible externally as a distinct prominence like the Adam's apple. Hyoid bone - The hyoid bone is a U-shaped bone located in the anterior neck between the chin and the thyroid cartilage. - It is unique because it is the only bone in the human body that does not articulate with any other bone; it serves as an anchor for muscles of the tongue and floor of the mouth. Cricoid cartilage - The cricoid cartilage is a ring-shaped cartilage located inferior to the thyroid cartilage, forming the base of the larynx. - While it is a part of the larynx, its anterior projection is not as prominent as that of the thyroid cartilage, and it does not form the "Adam's apple."

Q: Winging of scapula is due to paralysis of

Serratus anterior. ***Serratus anterior*** - The **serratus anterior muscle** is responsible for **protraction and rotation of the scapula**, holding it close to the thoracic wall. - Paralysis of this muscle, often due to injury to the **long thoracic nerve**, causes the **medial border of the scapula** to protrude posteriorly, a condition known as **medial scapular winging**. - This is the **classic and most common cause** of scapular winging. *Rhomboid major* - The rhomboid major muscle primarily performs **retraction and downward rotation of the scapula**. - Paralysis of this muscle would lead to the scapula being displaced laterally and superiorly, not winging. *Trapezius* - The trapezius muscle has multiple actions, including **elevating, depressing, retracting, and rotating the scapula**. - Paralysis of the trapezius (e.g., due to **accessory nerve damage**) can cause **lateral scapular winging** where the inferior angle protrudes, along with shoulder drooping and difficulty shrugging. - However, **serratus anterior paralysis** is the classic answer for scapular winging in exam contexts. *Levator scapulae* - The levator scapulae muscle is primarily involved in **elevating and downwardly rotating the scapula**. - Dysfunction of this muscle would impair shoulder elevation but would not be the direct cause of scapular winging.

Q: Which organelle contains its own DNA apart from the nucleus?

Mitochondria. ***Mitochondria*** - Mitochondria contain their own **circular DNA (mtDNA)**, which is inherited maternally, and their own ribosomes. - This DNA encodes for some proteins essential for **cellular respiration** and its own replication, supporting the endosymbiotic theory. *RER* - The **Rough Endoplasmic Reticulum (RER)** is characterized by the presence of **ribosomes** on its surface. - It plays a crucial role in the **synthesis and modification of proteins** designated for secretion or insertion into membranes, but does not contain DNA. *Golgi complex* - The **Golgi complex** is involved in **modifying, sorting, and packaging proteins and lipids** for secretion or delivery to other organelles. - It consists of flattened sacs called cisternae but does not possess DNA. *SER* - The **Smooth Endoplasmic Reticulum (SER)** is involved in **lipid synthesis**, **detoxification** of drugs and poisons, and **calcium ion storage**. - Unlike mitochondria, it does not contain its own genetic material.

Q: All of the following are manifestations of congenital syphilis except:-

Gumma. ***Gumma*** - **Gumma** is a manifestation of **tertiary syphilis** in adults, typically appearing years after the initial infection [1]. - While syphilis can be transmitted congenitally, **gummatous lesions** are not a characteristic finding in congenital syphilis [1]. *Olympian brow* - **Olympian brow** (also known as frontal bossing) is a feature of **congenital syphilis**, characterized by prominent frontal bones [2]. - It results from **periostitis** and abnormal bone development due to chronic infection in utero. *Interstitial keratitis* - **Interstitial keratitis** is a classic manifestation of **late congenital syphilis**, affecting the cornea [2]. - It presents as **bilateral corneal inflammation** leading to vision impairment, often appearing in childhood or adolescence. *Hutchinson's teeth* - **Hutchinson's teeth** are a pathognomonic sign of **congenital syphilis**, characterized by notched, peg-shaped, and widely spaced incisors. - This dental abnormality results from the treponemal infection disrupting the **enamel formation** during tooth development.

Q: Irreversible obstructive lung function is seen in which of the following conditions?

COPD. ***COPD*** - **Chronic Obstructive Pulmonary Disease** (COPD) is characterized by **persistent airflow limitation** that is not fully reversible [3]. - This irreversibility is due to structural changes in the airways and parenchyma, including **emphysema** and **chronic bronchitis** [2]. *Asthma* - Asthma is characterized by **reversible airway obstruction** and hyperresponsiveness, often triggered by allergens or irritants [4]. - While it can be severe, the key distinguishing feature is that the airway limitation can be significantly reversed with bronchodilator treatment [1]. *Pleural effusion* - A pleural effusion involves the **accumulation of fluid in the pleural space**, which is outside the lung tissue. - This condition causes **restrictive lung disease** by compressing the lung, rather than obstructing the airways from within, and is usually treatable by drainage. *Kyphoscoliosis* - **Kyphoscoliosis** is a skeletal deformity of the spine that restricts lung expansion, leading to **restrictive lung disease**. - It does not directly cause an obstructive pattern within the airways, but rather impairs the mechanical ability of the lungs to inflate.

Q: True about endometriosis:

Presence of endometrium at ectopic locations. ***Presence of endometrium at ectopic locations*** - **Endometriosis** is defined as the presence of endometrial glands and stroma outside of the uterine cavity. - These ectopic endometrial implants respond to hormonal changes, leading to cyclical pain and inflammation. *Presence of endometrial gland in deep myometrium* - This describes **adenomyosis**, a condition where endometrial tissue invades the muscular wall of the uterus (myometrium). - While both can cause pelvic pain, endometriosis specifically refers to endometrial tissue *outside* the uterus. *Treated preferably with hysterectomy* - Hysterectomy is a definitive treatment option, especially for severe cases or when fertility is not desired, but it is not the *preferred* initial treatment for all patients. - Initial management often includes **pain relievers**, **hormonal therapy**, or **laparoscopic excision** of endometriotic implants. *Seen in multiparous women* - Endometriosis is more commonly diagnosed in **nulliparous (never given birth)** or women who delay childbearing. - While it can occur in multiparous women, it is not a characteristic association.

Q: A G4P2 lady presented with history of two abortions at 16 weeks and 20 weeks POG. Which of the following could be the most likely reason for these abortions?

Cervical incompetence. ***Cervical incompetence*** - **Recurrent second-trimester pregnancy losses** (16 and 20 weeks) with a history of two previous abortions are highly suggestive of cervical incompetence, where the cervix dilates prematurely. - This condition is characterized by painless, progressive cervical dilation leading to **fetal expulsion** without contractions, which aligns with the presentation of repeated mid-trimester abortions. *Thyroid abnormality* - While **untreated hypothyroidism** or **hyperthyroidism** can increase the risk of miscarriage, these typically lead to **earlier first-trimester losses** or other obstetric complications, not recurrent mid-trimester abortions. - Abortion due to thyroid dysfunction is often associated with other signs and symptoms of thyroid disease, which are not mentioned. *Chromosomal abnormality* - **Chromosomal abnormalities** are the most common cause of **first-trimester miscarriages**, accounting for about 50% of them. - While they can cause later losses, recurrent mid-trimester abortions are less commonly attributed solely to chromosomal issues, especially in the absence of other malformations. *Placenta previa* - **Placenta previa** is a condition where the placenta partially or totally covers the cervix, causing painless vaginal bleeding in the **late second or third trimester**. - It increases the risk of preterm birth but is not a direct cause of recurrent fetal loss at 16 and 20 weeks gestation in the manner described.

Q: Tennis player can spontaneously reduce a shoulder dislocation. He can do it again and again himself. He is suffering from?

Recurrent shoulder dislocation. ***Recurrent shoulder dislocation*** - The ability to **spontaneously reduce** a shoulder dislocation, and the history of it happening "again and again" strongly indicate **recurrent shoulder dislocation**. - This condition often results from **ligamentous laxity** or damage to the **labrum** (Bankart lesion) that fails to stabilize the shoulder joint after an initial dislocation. *Inferior shoulder dislocation* - This is a **specific type of shoulder dislocation** (luxatio erecta) where the humeral head is displaced inferiorly, but "inferior" alone does not explain the recurrent nature. - While possible in an individual, the key element here is the **recurrence** and self-reduction, not just the direction of a single dislocation. *Fracture upper end humerus* - A fracture of the upper end of the humerus is a **bony injury** and would typically present with severe pain, swelling, and inability to move the arm, not spontaneous reduction. - This injury would usually **prevent** the patient from repeatedly dislocating and reducing their shoulder. *Acute shoulder dislocation* - An acute shoulder dislocation refers to a **single, recent episode** of dislocation. - The patient's repeated ability to self-reduce the shoulder indicates a chronic problem rather than an initial, isolated event.

Q: Negative symptoms of schizophrenia are all except:-

Over activity. ***Over activity*** - **Overactivity** is a manifestation of disorganized or positive symptoms in schizophrenia, such as **agitation** or purposeless movements, rather than a deficiency. - While it can occur in schizophrenia, it represents an excess or distortion of normal function, distinguishing it from **negative symptoms** which reflect a reduction or absence of typical behaviors. *Apathy* - **Apathy**, or avolition, is a core negative symptom characterized by a **lack of motivation** and an inability to initiate or persist in goal-directed activities. - Patients with apathy often show diminished interest in daily activities and personal care. *Anhedonia* - **Anhedonia** is a negative symptom defined by the **inability to experience pleasure** from activities that are usually enjoyable. - This can include a loss of interest in social interactions, hobbies, and other rewarding experiences. *Alogia* - **Alogia**, or poverty of speech, is a negative symptom characterized by a **reduction in the quantity and fluency of speech**. - Individuals with alogia may provide brief, empty responses and exhibit long pauses during conversation.
