Answer 3

the flow of information toward the cell body

Question 4

efferent

Answer 4

information flowing out of the cell body

Question 5

action potential

Answer 5

a nerve carries info by conducting electrical impulses

Question 6

peripheral nervous system

Answer 6

anything outside the spinal column and out

Question 7

Trigeminal nerve

Answer 7

sensory an motor nerve, largerst cranial nerve, motor never=chewing sensory

Question 8

facial nerve Vll

Answer 8

mixed. sensory=partly responsibe for taste. Motor nerve=facial movements ad expression.

Question 9

vestibular acoustic nerve Vlll

Answer 9

Sensor only. 2 branches. vestibular- which is concerned with the sense of balance and head position. Acoustic- carries sensory information to the brain

Question 10

vagus nerve X

Answer 10

called the wandering nerve because it wander into the chests and stomach as well as the cranium. sensory an motor and autonomic fiber. recurrent laryngeal nerve- important for speech, right and left branches regulate the intrinsic muscles of the larynx.

Question 11

glossopharyngeal nerve lX

Answer 11

mixed nerve. also contains fibers. sensory= supplies the tongue. Motor= supplies the pharynx, helps regulate the movement of the muscles in the pharynx.

Question 12

accessory nerve Xl

Answer 12

motor nerve. both cranial and spinal nerve because it has cranial and spinal origins. Regulates muscles of the pharynx and the soft palate and also involves head and shoulder movement.

Question 13

hypoglossal nerve Xll

Answer 13

motor nerve to the tongue. nerve controls most of the tongue movements

Question 14

Answer 14

31 pairs

Question 15

autonomic nervous system

Answer 15

controls the internal environment.(the way we change and apapt the an environment.

Question 16

Sympathetic and parasympathetic are….?

Answer 16

supplies the smooth muscles within the body and the various glands that secrete hormones

Question 17

sympathetic branch in detail

Answer 17

mobilizes the body so that is can cope with emergencies.

Question 18

parasympathetic branch in detail

Answer 18

help bring the mobilized body back into a relaxed state.

for speech language and hearing.

Question 26

Occipital lobe is for what?

Answer 26

primarily concerned with vision. above the cerebellum and behind the parietal lobe

Question 27

Parietal lobe

Answer 27

sensations for pain, touch temperature and pressue. such sensations are called somesthetic. 2 special areas supramarginal gyres and angular gyrus- involves speech and language. begins posterior to the central sulcus and contains sensory cortex

Question 28

temporal lobe

Answer 28

also important for speech , language and hearing. primary auditor cortex- temporal lobe sits here and receives sound stimuli. wernickes area- understanding and formulating speech and left of the temporal lobe

Question 29

frontal lobe

Answer 29

largest of the 4 lobes. , located behind the forehead.m Motor cortex- includes Broca's area ( the major speech-language and hearing areas of the brain.

Question 30

Question 33

gyri

Answer 33

ridge on the cortex.

Question 34

sulci

Answer 34

on the brain surface. (shadow valley)

Question 35

fissures

Answer 35

fewer and deeper sulci, deeper valleys.

Question 36

longitudinal fissues

Answer 36

divides the cerebrum into the left and right hemispheres

Question 37

fissure of rolando

Answer 37

creates the frontal portion of the brain
