Exam 15: Brain and Cranial Nerves

Bell palsy is a condition characterized by the paralysis of facial muscles,eyelid droop,and sagging at the corners of the mouth.What nerve is affected in this condition?

-This figure shows the lobes of the cerebrum.What structure does number 1 indicate?

A tumor is located in a young boy's brain.Symptoms include the inability to swallow and inability to detect odors.What is the most likely location of the tumor?

This part of the brain contains the flocculonodular lobes.

Which part of the brain contains the epithalamus,hypothalamus,and the thalamus?

A brain ventricle located in the cerebrum is the _____ ventricle.

The horizontally oriented fold of dura mater that separates the occipital and temporal lobes of the cerebrum from the cerebellum is the

The most caudal part of the brain,the _________,is continuous with the spinal cord.

In both the cerebrum and the cerebellum,white matter lies deep to superficial gray matter.

This portion of the brain adjusts skeletal muscle activity to maintain equilibrium and posture.

The largest of the four dural septa,this large,sickle-shaped vertical fold of dura mater separates the left and right cerebral hemispheres.

Arrange the primary brain vesicles in the correct anterior to posterior order. A: Rhombencephalon B: Mesencephalon C: Prosencephalon

The mesencephalic (cerebral)aqueduct carries CSF from the lateral ventricles to the third ventricle.

This portion of the brain ensures that skeletal muscle contraction follows the correct pattern leading to smooth,coordinated movements.

This portion of the brain forms part of the roof of the diencephalon and covers the third ventricle.Its posterior portion houses the pineal gland and the habenular nuclei.

This nucleus processes visual information at a subconscious level.

-This figure shows a frontal section of the cerebrum.What structure does number 1 indicate?

Cerebrospinal fluid is formed by the

Cerebrospinal fluid is identical to blood plasma.

-This figure shows a left lateral view of the brain.What lobe does number 2 indicate?
