No sensory information, with the exception of olfactory information, reaches the cerebral cortex without a synaptic stop in some part of the ______.

Thalamus

The ______ marks the rostral end of the closed medulla.

Gracile Tubercle

The fibers from this nuclei enter the cerebellum via the middle cerebellar peduncle.

Pontine Nuclei

- contained by the basis pontis

The inferior and superior colliculi together constitute the ______ .

Corpora Quadrigemina

- synonymous with the tectum of the midbrain

This is the largest commissure of the brain.

Corpus Collosum

Foramina of Monro

The arched formation below the corpus collosum

fornix

The ____ sulcus runs perpendicular to the Parietooccipital Sulcus in the Occipital Lobe.

Calcarine sulcus

In sagittal section the gyrus immediately superior to the corpus callosum is the ______.

Cingulate Gyrus

What two gyri comprise the primary visual cortex?

The two gyri above and below the calcarine sulcus in the occipital lobe: cuneus (above) and lingual (below)

Cerebrospinal fluid is secreted by this secretory tissue affixed at certain locations within the ventricular system.

choroid plexus

- located in the inferior medullary velum, for example

The part of the 4th ventricle which projects into the inferior surface of the cerebellum.

fastigium

The rostral and caudal surfaces of the 4th ventricle are enclosed by what surfaces?

The superior and inferior medullary velum, respectively.

The area of the brain stem inferior to the cerebral aqueduct

tegmentum  ("floor") of the midbrain

The area of the mesencephalon superior to the cerebral aqueduct

tectum ("roof")

or

corpora quadrigemina

Represents the original rostral tip of the embryonic neural tube

lamina terminalis

True or False:

The corpus callosum, thalamic adhesion, and anterior commissure all connect the right and left sides of the brain.

False

The thalamic adhesion (aka massa intermedia) is not a commissure. The other two are.

A groove that separates the thalamus from the hypothalamus below

hypothalamic sulcus

Secretes melatonin and is visible below the splenium of the corpus callosum

Pineal gland

True or False:

Grey matter overlies white matter in the cerebellum.

True

The hypoglossal nerve (CN XII) is a somatic motor nerve that controls the intrinsic and extrinsic muscles of the ______.

tongue

The accessory nerve (CN XI) is a motor nerve that innervates which 2 muscles?

The Sternocleidomastoid and the Trapezius

 _____ has sensory, motor, and parasympathetic components that provide autonomic innervation to visceral organs.

CN X - vagus

_____ provides motor and sensory innervation to the pharynx and larynx as well as autonomic and visceral sensory information to CV and respiratory structures.

CN IX - glossopharyngeal

What are the 2 parts of CN VIII?

Where does it enter the skull?

acoustic division - auditory info from inner ear

vestibular division - equilibrium info from labyrinth

-enters skull through internal acoustic meatus

What 2 cranial nerves pass through the internal acoustic meatus?

CN VIII (vestibulocochlear)

CN VII (facial)

Which cranial nerve innervates the lateral rectus muscle?

CN VI - Abducens

-abducts the eye
