INI-CET 2009

Q: Orbital blow-out fracture involves:

Medial wall and floor of orbit. Medial wall and floor of orbit - An orbital blow-out fracture typically involves the **medial wall** (lamina papyracea of the ethmoid bone) and the **floor** (maxillary bone) of the orbit because these are the weakest bony structures. - The force of impact on the globe is transmitted to the orbital walls, causing them to fracture outwards into the adjacent sinuses. *Lateral wall and roof of orbit* - The **lateral wall** (zygomatic bone) and **roof** (frontal bone) of the orbit are structurally strong and less commonly involved in isolated blow-out fractures. - Fractures in these areas typically result from high-impact trauma and are often associated with other facial bone injuries. *Medial wall and roof of orbit* - While the **medial wall** is frequently involved, the **roof** of the orbit is a thick, sturdy bone and is less susceptible to blow-out forces. - Fractures of the orbital roof usually occur due to direct impact or high-energy trauma to the forehead. *Lateral wall and floor of orbit* - Although the **floor** is commonly fractured, the **lateral wall** is a robust structure and is not typically involved in isolated blow-out fractures. - Combined fractures of the lateral wall and floor would indicate a more extensive orbital impact, often with other mid-facial trauma.

Q: ABO antigens are not found in:

CSF. ***CSF*** - ABO antigens are typically expressed on the surface of **red blood cells** and in the secretions of individuals classified as **secretors**. - **Cerebrospinal fluid (CSF)** is generally devoid of these antigens. *Semen* - ABO antigens can be found in **semen**, particularly in individuals who are secretors. - This is due to the presence of **secreted bodily fluids** containing soluble forms of these antigens. *Saliva* - **Saliva** is a well-known source of soluble ABO antigens in secretor individuals. - The presence of these antigens in saliva is often used in **forensic testing** and blood group determination. *Tears* - Similar to other bodily secretions, **tears** can contain soluble ABO antigens in secretor individuals. - This is part of the general secretion of these antigens into exocrine fluids.

Q: Which of the following conditions is characterized by webbing of the neck, short stature, increased carrying angle, low posterior hairline, primary amenorrhea, and short fourth metacarpal?

Turner syndrome. ***Turner syndrome*** - Characterized by **webbing of the neck**, **short stature**, and **primary amenorrhea**, which are classic features of Turner syndrome [1][2]. - The presence of a **short fourth metacarpal** is also a specific skeletal manifestation associated with this condition. - **Short stature** in Turner syndrome is specifically explained by haploinsufficiency of the SHOX gene [1]. *Noonan syndrome* - Presents with features like **short stature** and **cardiac anomalies**, but lacks the specific manifestations of neck webbing and primary amenorrhea. - Typically associated with facial dysmorphisms, such as **widely spaced eyes** and a **distinctive appearance** which are not mentioned here. *Klinefelter syndrome* - Characterized by **47,XXY** karyotype leading to **gynecomastia** and **testicular atrophy**, rather than symptoms like webbed neck or short stature. - Men with this syndrome usually display **delayed or incomplete puberty**, not primary amenorrhea. *Cri-du-chat syndrome* - Primarily associated with a **distinctive high-pitched cry** and developmental delays, rather than physical traits like webbed neck or short fourth metacarpal. - Symptoms are more related to **chromosomal deletion** and do not include amenorrhea or features typical of Turner syndrome. **References:** [1] Kumar V, Abbas AK, et al..

About INI-CET 2009 Questions

This page contains 3 questions from the INI-CET 2009 paper, organised across 3 subjects for focused practice. Every question comes with the correct answer and a detailed explanation to help you understand the underlying concept. Subject-wise organisation lets you target specific areas and identify which topics carried the most weight in this particular year.

Practising year-wise papers is essential for understanding how the INI-CET exam evolves — you can spot trending topics, gauge difficulty shifts, and benchmark your readiness against a real paper. To take your preparation further, download the Oncourse app for AI-driven performance insights, spaced repetition of questions you got wrong, and a personalised study plan built around your INI-CET goals.
