Accepted Answer

Ridges of tissue on the surface of the cerebral hemispheres are called gyri.

Question 3

Which fissure separates the cerebral hemispheres?&#10;A) lateral sulcus&#10;B) longitudinal&#10;C) parieto-occipital fissure&#10;D) central fissure

Accepted Answer

The longitudinal fissure separates the two cerebral hemispheres.

Question 4

The abducens nerve ________.&#10;A) supplies innervations to the lateral rectus muscle of the eye&#10;B) relays sensory information from the taste buds on the tongue&#10;C) innervates the olfactory epithelium&#10;D) exits from the medulla

Accepted Answer

The abducens nerve innervates the lateral rectus muscle of the eye, which is responsible for lateral eye movement.

Question 5

The primary auditory cortex is located in the ________.&#10;A) temporal lobe&#10;B) parietal lobe&#10;C) prefrontal lobe&#10;D) frontal lobe

Accepted Answer

The primary auditory cortex is located in the temporal lobe of the brain, specifically in the superior temporal gyrus. It is responsible for processing auditory information and is involved in tasks such as sound localization and speech perception.

Question 6

The cranial nerve that originates from both the medulla oblongata and the spinal cord is the ________.&#10;A) vagus&#10;B) hypoglossal&#10;C) accessory&#10;D) glossopharyngeal

Accepted Answer

The accessory nerve (cranial nerve XI) is unique because it has both cranial and spinal roots. It originates from the medulla oblongata and the upper part of the spinal cord.

Question 7

The ________ nerve is NOT a branch of the trigeminal nerve.&#10;A) ophthalmic&#10;B) maxillary&#10;C) mandibular&#10;D) cervical

Accepted Answer

The cervical nerve is not a branch of the trigeminal nerve. The ophthalmic, maxillary, and mandibular nerves are all branches of the trigeminal nerve.

Question 8

What is the specialized capillary called inside each ventricle where cerebrospinal fluid is produced?&#10;A) astrocytes&#10;B) ependymal cells&#10;C) choroid plexus&#10;D) neurons

Accepted Answer

The choroid plexus is a specialized structure located in the ventricles of the brain, consisting of capillaries and ependymal cells, which is responsible for the production of cerebrospinal fluid (CSF).

Question 9

The arbor vitae refers to ________.&#10;A) cerebellar gray matter&#10;B) cerebellar white matter&#10;C) flocculonodular lobe&#10;D) ascending tracts

Accepted Answer

The arbor vitae is the distinctive pattern of white matter in the cerebellum, named because of its tree-like appearance on cross-section.

Question 10

What area of the brain contains the primary motor cortex, where voluntary commands to skeletal muscles are generated?&#10;A) postcentral gyrus&#10;B) occipital lobe&#10;C) precentral gyrus&#10;D) temporal lobe

Accepted Answer

The precentral gyrus, which is located in the frontal lobe, contains the primary motor cortex where voluntary commands to skeletal muscles are generated.
