Neuroanatomy — Flashcards

Flashcard 391: The post-ganglionic neurons of the ANS have cell bodies in the _____ nervous system

Answer: peripheral

Flashcard 392: Which brainstem pathway carries fine touch, vibration, and proprioception from the body to the VPL nucleus of the thalamus?

Answer: Medial lemniscus

Extra: The medial lemniscus is formed by the decussation of second-order neurons (internal arcuate fibers) from the nucleus gracilis and cuneatus in the medulla. It carries fine touch, vibration, and proprioception to the VPL nucleus of the thalamus.

Flashcard 393: Where is the nucleus of CN XI (accessory nucleus) located? _____

Answer: Spinal cord

Flashcard 394: Most fibers in the optic tract project to the _____ of the thalamus

Answer: lateral geniculate body

Flashcard 395: The _____ comprises the nerve roots of lumbar, sacral, and coccygeal spinal nerves below the conus medullaris

Answer: cauda equina

Flashcard 396: Identify the cortical area located in the superior parietal lobule.

Answer: Somatosensory association cortex (Brodmann areas 5 and 7)

Flashcard 397: Which structure forms the lateral part of the lentiform nucleus?

Answer: Putamen

Extra: The lentiform nucleus consists of the putamen (lateral) and the globus pallidus (medial). It is located lateral to the internal capsule.

Flashcard 398: The _____ is slender pial extension that tethers the spinal cord to the bottom of the vertebral column

Answer: filum terminale

Flashcard 399: Colloid cysts are a pathologically benign tumor usually found in the _____

Answer: 3rd ventricle

Flashcard 400: Which brainstem level is characterized by the presence of the 4th ventricle, inferior olivary nucleus, and cranial nerves IX, X, and XII?

Answer: Open Medulla
