A And P 15

Front 1

Sensory

Back 1

send signals to CNS

Front 2

Integrative systems

Back 2

process and eveuate sensory information (integration_

Front 3

motor systems

Back 3

carry signals from CNS to effectors, and make sure motor output is coordinatied for efficient responses

Front 4

sensory modality

Back 4

type of sensation.. touch, vision

Front 5

perception

Back 5

awareness plus interpretation of sensory

Front 6

somatic sensations include

Back 6

tactile
thermal
pain
proprirreception

of the body sensations

Front 7

tactile sensations

Back 7

tactile receptors of the skin include
corpuscles of touch (messiner corpuscles)
hair root plexuess
mrechanoreceptors
merkel discs
ruffini corpuscles
lamellanatied corpucles
free nerve sensations

Front 8

nociceptors

Back 8

free nerve endings that respond to
chemical and physical damage
activated by multiple types
chemicals can stimulate/sensitize

Front 9

superficial somatic pain

Back 9

arises from nociceptors in the skin

Front 10

deep somatic pain arises from

Back 10

nociceptors in the muslcesm joints, tendons, ligaments, and facia

Front 11

visceral pain

Back 11

arises from stiulation of nociceptors in visceral organs

Front 12

proprioceptive sensations allow

Back 12

us to have waareness of where our head and limbs are, and where they are going... cirital for precise control of body movements
inform us about several categories of mechanical stimuli

Front 13

prociceptors inform us about

Back 13

the degree to which muslces are stretched
tension in tendons, position of joints
position and movements of our head

Front 14

feedback from proprioceptors allow

Back 14

us to adjust our movements to match changing physical challenges

Front 15

muscle spindles

Back 15

lenth of muslces is monitored by proprioceptors
stretch reflex/tone of muscle

Front 16

tendon organs

Back 16

where tendon meets mucle
level of tension is moniitored by priceptors

Front 17

joint kinethetic receptors

Back 17

located within and around synotvial joint capsules
provide feedback on joint position

Front 18

primary somatosensory area is in the

Back 18

postcentral gysus of the parietal lobe

Front 19

left side of the body maps to the
(somatic sensory map)

Back 19

right cerebral cortex

Front 20

primary motor area

Back 20

precentral gyrus of the frontal lobe

Front 21

first order neurons carry

Back 21

signals to teh spinal cord or brainstem

Front 22

second order neurons

Back 22

to thalamus

Front 23

third order neurons

Back 23

from thalamus to cerebral cortex

Front 24

relay stations

Back 24

in CNS, spinal cord, regions of brinstem, thalmus

Front 25

posterior colum pathway

Back 25

cafrries ifo from touch, vibration, proprioreceptors

Front 26

anterolareal pathway

Back 26

pain., touch, temp, itch, tickle

Front 27

cerebellum

Back 27

maintains balance posture, executes skilled movements
(requires extenstive input from prpprioceptors

Front 28

skeletal mucles innertaved by

Back 28

lower motor neurons )spinal cord or brainstem)

Front 29

uppor motor neurons maintain

Back 29

muscle tone, posteru, balance

Front 30

balal nuclei help

Back 30

begin and end movements

Front 31

wakefullness and sleep regulated by

Back 31

thalamus

Front 32

reticular activiating system is a

Back 32

diffuse series of brainstem nuclei that elp us transition b/w sleep and awake

Front 33

integrative functions

Back 33

area of the brain involved in memory include associatoin areas (talmus and hypo) and parts of the limbic system
