Flashcards in Chapter 14 Deck (28):
0

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

Cerebrum

1

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

Cerebellum

2

Connects the cerebellum to the brain stem. In addition to tracts and relays centers the pons also contains nuclei involved with somatic and visceral motor control

Pons

3

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

Medulla oblongata

4

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

Diencephalon

5

The membrane the region between the diencephalon and pons

Mesencephalon

6

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

Ventricle

7

The isolation of the central nervous system from the general circulation, primarily the results of astrocyte regulation of capillary permeability

Blood brain barrier

8

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

9

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

Cerebral hemisphere

10

The nerve fiber bundles on the ventrolateral surfaces of the mesencephalon

Cerebral peduncles

11

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

Limbic system

12

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

Gyri

13

A groove or or furrow

Sulcus

14

An elongated groove or opening

Fissure

15

A graphic record of the electrical activities of the brain

Electroencephalogram

16

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

Optic nerve

17

Cranial nerve 3 which controls the extra ocular muscles other than the superior oblique and the lateral rectus muscles

Oculomotor nerve

18

Cranial nerve controlling the superior oblique muscle of the eye

Trochlear nerve

19

Cranial nerve 5 which provides sensory information from the lower portions of the face and delivers motor commands to the muscle of mastication

Trigeminal nerves

20

Cranial nerve 6 which innervates the lateral rectus muscle of The eyes

Abducens nerve

21

Lies along the edge of the premotor cortex in the same hemisphere as the general interpretive area

Speech center

22

Axons from these sensory neurons collected to from 20 or more bundles that penetrate the cribriform plate of the ethmoid bone

Old factory nerves

23

Are mixed nerves

Facial nerves

24

Are also know as the acoustic nerves the auditory nerves and stato-acoustic nerves

Vestibulocochlear nerves

25

Innervates the tongue and pharynx

Glossopharyngeal nerves

26

Arise immediately posterior to the attachment of the glossopharyngeal nerves

Vagus nerves

27

Leaves the cranium through the hypoglossal canal, the nerve then curves to reach the skeletal muscle of the tongue

Hypoglossal nerve
