Flashcards in Chapter 14 Corrected Deck (28):
1

The largest portion of the brain, composed of the cerebral hemispheres, includes the cerebral cortex, the basal nuclei, and the internal capsule.

Cerebrum

2

The posterior portion of the mesencephalon, containing the cerebellar hemispheres, includes the arbor vitae, cerebellar nuclei, and cerebellar cortex.

Cerebellum

3

The portion of the metencephalon that is anterior to the cerebellum.

Pons

4

The most caudal of the brain regions, also called the myelencephalon.

Medulla Oblongata

5

A division of the brain that includes the epithalamus, thalamus, and hypothalamus.

Diencephalon

6

The midbrain; the region between the diencephalon and pons.

Mesencephalon

7

A fluid-filled chamber; in the heart, one of the large chambers discharging blood into the pulmonary or systemic circuits; in the brain, one of four fluid-filled interior chambers.

Ventricles

8

The isolation of the central nervous system from the general circulation; primarily the result of astrocyte regulation of capillary permeabilities.

Blood-Brain Barrier

9

The floor of the diencephalon; the region of the brain containing centers involved with the subconscious regulation of visceral functions, emotions, drives, and the coordination of neural and endocrine function.

Hypothalamus

10

A pair of expanded portions of the cerebrum covered in neural cortex.

Cerebellar Hemispheres

11

The nerve fiber bundles on the ventrolateral surfaces of the mesencephalon.

Cerebellar Peduncles

12

The group of nuclei and centers in the cerebrum and diencephalon that are involved with emotional states, memories, and behavioral drives.

Limbic System

13

A prominent fold or ridge of neural cortex on the surfaces of the cerebral hemispheres.

Gyri

14

A groove or furrow.

Sulci

15

An elongated groove or opening.

Fissures

16

Some of the neurons in the general interpretive area innervate here, also called the Broca area or the motor speech area. this center lies along the edge of the premotor cortex in the same hemisphere as the general interpretive area.

Speech Center

17

A printed record of the brain's electrical activity over time.

Electroencephalogram

18

The first pair of cranial nerves, carry special sensory information responsible for the sense of smell.

Olfactory Nerves

19

The second cranial nerve, which carries signals from the retina of the eye to the optic chiasm.

Optic Nerves

20

Cranial nerve III, which controls the extra-ocular muscles other than the superior oblique and the lateral rectus muscles.

Oculomotor Nerves

21

Cranial nerve IV, controlling the superior oblique muscle of the eye.

Trochlear Nerves

22

Cranial Nerve V, which provides sensory information from the lower portions of the face (including the upper and lower jaws) and delivers motor commands to the muscles of mastication.

Trigeminal Nerves

23

Cranial nerve VI, which innervates the lateral rectus muscle of the eye.

Abducens Nerves

24

Are mixed nerves. The cell bodies of sensory neurons are located in the geniculate ganglia, and the motor nuclei are in the pons.

Facial Nerves

25

Are also known as the acoustic nerves, the auditory nerves, and the state-acoustic nerves.

Vestibulocochlear Nerves

26

Cranial nerve IX. Innervates the tongue and pharynx.

Glossopharyngeal Nerves

27

Arise immediately posterior to the attachment of the glossopharyngeal nerves.

Vagus Nerves

28

Leaves the cranium through the hypoglossal canal; the nerve then curves to reach the skeletal muscles of the tongue.

Hypoglossal Nerves
