Psych 2 - Nervous System

Front 1

central nervous system CNS

Back 1

division of teh enrvous system that is located within the skull and spine

Front 2

peripheral nervous system PNS

Back 2

division that is located outside the skull and spine

Front 3

somatic nervous system SNS

Back 3

part of the PNS that interacts with teh external environemtn

Front 4

afferent nerves

Back 4

that carry sensory signals FROM the skin, skeletal miuscles, joints, eyes, ears and so on to the central nervous system.

Front 5

efferent nerves

Back 5

that carry motor signals from the central nervous system to teh skeletal muscles.

Front 6

autonomic nervous system ANS

Back 6

is the part of teh peripheral nervous system that regulates teh body's internal environment.

Front 7

autonomic nervous system has two kinds of efferent nerves:

Back 7

sympathetic nerves and parasympathetic nerves

Front 8

sympathetic nerves

Back 8

autonomic motor nerves that project from teh CNS in teh lumbar (small of teh back) AND THORACIc (chest area) regions spinal cord

Front 9

parasympathetic nerves

Back 9

are those autonomic motor nerves that project from the brain and sacral lower back region of the spinal cord.

Front 10

how many cranial nerves that we have to remember

Back 10

12 and there is three main ones, the olfactory nerves, optic nerves and teh vagus nerves.

Front 11

meninges name them from top to bottom

Back 11

dura mater, arachnoid membrane, and subarachnoid membrane. then pia mater.

Front 12

cerebrospinal fluid

Back 12

CSF fill teh subarachnoid space and protects teh CNS

Front 13

central canal

Back 13

small central channel that runs the lenght of the spinal cord

Front 14

blood brain barreir

Back 14

impede the passage of many toxic substances fomr teh blood in to the brain.

Front 15

glial cells

Back 15

glial cells outnumber enurons by 10 to 1

Front 16

tracts

Back 16

bundles of axons

Front 17

in teh PNS they are called

Back 17

nerves

Front 18

oligondendrocytes

Back 18

one clas of glial cells that wrap aorund teh axons of some neruons of the CNS rich in myelin

Front 19

schwann cells

Back 19

second class of glial cells, constitues of one myelin seegment

Front 20

astrocytes

Back 20

third class, larges , star shaped, cover teh outer surfaces of blood vessels

Front 21

microglia

Back 21

fourth class, respond to injury or diseases by engulfing cellular debris and tirggering inflammatory responses.

Front 22

golgi stain

Back 22

stains all teh neurons on a lside reveal nothin of their struvtures

Front 23

nissal stain

Back 23

penetrates all teh cells on a slide and bide to teh neuron cell bodies so you can see each one oneby one and count them

Front 24

NAME THE DIRECTIONS OF THE NERVOUS SYSTEM

Back 24

DORSAL VENTRAL ANTERIOR POSTERIOR MEDIAL AN DLATERAL

Front 25

four ways to split the brain

Back 25

SGGITTAL HORIZONTAL CROSS SECTION AND FONTAL

Front 26

corss section

Back 26

section cut at a right angle to any long, narrow structures such as teh spinal cord.

Front 27

brain stem

Back 27

the stem on which the cerbral hemispheres

Front 28

gray matter

Back 28

largely of cell bodies and unmyelinated interneruons

Front 29

white

Back 29

composed largey of meylinated axons.

Front 30

coillection of cell bodeies

Back 30

in CNS its nuclei
in PNS its ganglia

Front 31

bundles of axons

Back 31

in CNS tracts
in PNS nerves

Front 32

hippocampus

Back 32

a structure of the medil temporal lobes that plays a role in memory for spatial location.

Front 33

amygdala

Back 33

sometign with emotions

Front 34

CTLSC

Back 34

Cervical Thoracic Lumbar Sacral Coccygeal

Front 35
