Neuro 3050 Exam 1 Practice Questions
with Complete/Correct Answers 2026
Updated.
central NS - Answer brain and spinal cord
peripheral NS - Answer -12 pairs of cranial nerves
-31 pairs of spinal nerves
-ganglia
ganglia - Answer -greek for tumor; anything gathered in a ball
-located outside CNS that contains neurons
-ex: enlargements after leaving SC
nucleus - Answer collection of neurons in the CNS
orientations - Answer Rostral:
-toward nose
-head = nose side = anterior
-body = upward
Caudal:
-toward tail
-head = back of head = posterior
-body = downward
Dorsal
-"fin"
-head = top of head = superior
-body = backside = posterior
Ventral:
-head = bottom surface = inferior
-body = belly side = anterior
, planes of section - Answer -transverse = horizontal = makes top and bottom
-coronal = like a crown = makes front and back
-sagittal = makes left and right
-parasagittal = off midline
telencephalon - Answer -forebrain
-cerebral cortex and subcortical nuclei
-most rostral
-CN # 1
diencephalon - Answer -thalamus and hypothalamus
-second most rostral section
-CN # 2
-2 mamillary bodies (bumps)
-optic tract, nerve, and chiasm
hindbrain/midbrain - Answer -rostral to pons
-caudal to diencephalon
-smallest part of brainstem
interpeduncluar fossa = conformation change between pons and CN3
-cerebral peduncle = bundle of axons descending & continuous with pyramids
-CN # 3
tectum - Answer -roof of tegmentum
-2 SC and 2 IC
-refelxes and relays
-CN 4 arises here (dorsal)
-birds have big tectums
pons - Answer -means bridge
-enlargement rostral to medulla
-horizontal "planks" = axons
-CN # 4 and 5
