Brain and Neuroanatomy — Flashcards

Flashcard 71: _____ sinus and superior sagittal sinus drain into the confluence of sinuses

Answer: Occipital

Flashcard 72: The auditory input from the superior olivary nucleus travels via the _____ to the inferior colliculus (midbrain)

Answer: lateral lemniscus

Flashcard 73: In **Polysomnography**, continuous EEG monitoring is recorded from _____, Central, and Occipital leads attached to the scalp.

Answer: Frontal

Extra: According to AASM (American Academy of Sleep Medicine) guidelines, the recommended EEG derivations for sleep staging include Frontal (F4-M1), Central (C4-M1), and Occipital (O2-M1) electrodes. These are non-invasive electrodes attached to the scalp, not the brain. - **Occipital leads:** Best for identifying alpha rhythm (eyes closed wakefulness). - **Central leads:** Best for identifying sleep spindles and K-complexes (Stage N2). - **Frontal leads:** Best for identifying slow-wave activity (Stage N3).

Flashcard 74: One component of the basal ganglia is the _____, which consists of the putamen (motor) and caudate (cognitive)

Answer: striatum

Flashcard 75: The _____ cistern contains the AICA artery, cranial nerves 5, 7, 8 and superior petrosal veins

Answer: Cerebellopontine

Flashcard 76: What is the output of the neocerebellum?To _____ nucleus of the thalamus via the dentate nucleus

Answer: ventrolateral

Flashcard 77: The basal ganglia and cerebellum funnel information for skilled voluntary movement to the _____ and motor cortex by way of the thalamus.

Answer: premotor

Flashcard 78: The innervation of the cranial dura mater is derived mainly from the three divisions of the _____ cranial nerve, the C2 and C3 spinal nerves, and the cervical sympathetic trunk.

Answer: 5th

Flashcard 79: Branches of Mandibular nerve:Main trunk of the mandibular nerve gives rise to _____ and Nervous spinosus

Answer: N. to medial pterygoid

Flashcard 80: The dentate nucleus sends axons that decussate in the _____ and then synapse in the contralateral ventral lateral (VL) nucleus of the thalamus

Answer: superior cerebellar peduncle
