1

What are the motor functions of cranial nerves I and II?

Cranial nerves I (olfactory) and II (optic) do not have motor functions; they are purely sensory.

2

The median nerve is located in which region of the nervous system?

Peripheral

3

Ventral roots are located in which region of the nervous system?

Spinal

4

The Medulla is located in which region of the nervous system?

Brainstem (Cerebellar)

5

The Diencephalon is located in which region of the nervous system?

Cerebral

6

What two systems provide essential nutritive support to the nervous system?

1. cerebrospinal fluid 2. vascular systems

7

What is a midsagittal section of the brain?

A section of the brain produced by dividing the brain into left and right halves.

8

What is a lemniscus?

A bundle of myelinated axons within the central nervous system

9

What is the difference in function between white and gray matter?

White matter consists of myelinated axons that convey information among parts of the nervous system. Gray matter consists of neuronal cell bodies that function in signaling and information integration.

10

What is the function of the peripheral nervous system?

Conveys information from sensory receptors into the central nervous system (CNS) and from the CNS to skeletal muscles, smooth muscles, and glands.

11

What is the function of the spinal nervous system?

Conveys somatosensory information between to the brain and conveys signals from the brain to neurons that directly control movement.

12

What is the function of the brainstem (cerebellar) nervous system?

Conveys information between the cerebrum and spinal cord. Is the region of sensory and motor integration and controls vital functions.

13

What is the function of the cerebral nervous system?

Is involved in motor control, sensory processing memory, reasoning, and verbal and/or nonverbal communication.

14

Vertebral Artery

15

Off of what major artery does the Posterior inferior cerebellar artery branch from?

16

Off of what major artery does the Anterior inferior cerebellar artery branch from?

Basilar Artery

17

Off of what major artery does the Posterior cerebral artery branch from?

Basilar Artery

18

Off of what major artery does the Superior cerebellar artery branch from?

Basilar Artery

19

Off of what major artery does the Anterior cerebral artery branch from?

Internal Coratid Artery
