encapsularted nerve endings

Answer 7

tactile, lamellar corpuscles, bulbous corpuscles

Question 8

lamellar corpucscules

Question 9

bulbous corpuscles

Question 10

encapsualted nerve endings

Question 11

Question 17

descending motor pathways

Question 18

cortiocspinal and corticobulbar tracts

Question 19

desceding pathways and tracts

Answer 19

direct vis indirect pathways. upper vs lower motor neuons

Question 20

lateral vs ventral spinal tracts (decsiming motor pathways)

Question 21

relfex ark

Question 22

inborn (intrinsic( relfex vs leared (aquried reflex)

Question 23

five basic compontenst of all relfex arc

Answer 23

recpetos, sensory neuron, integration center, motor neuron, effector

Question 24

somatc spinal reflexes

Answer 24

no invoelent of higher brain, is clinically assessed

Question 25

stretch and tendon reflex

Question 26

muscle spindles

Answer 26

send info of length of msucle, encapsulated NE, can contract in the end, central regions of intrafusal msucle fibers non contract. effecto fibers of muscle reffered to as extrafusal msucle fibersm

Question 27

2 types of affernt endings in msucle spindle

Answer 27

anulospral endings and flower spray endings

Question 28

anulospral endings

Answer 28

primary seonsyr endings, wrap around the spindle, stimulated by rate and degree tretc

Question 29

flower spray endings

Answer 29

secondary seosnry endings, small azons at spindle ends, stimulated by degree of stretch only

Question 30

msucle spindles - motor fibers (gamma and alpha)

Answer 30

conrtactile regions inervated by Y effernt (spindle sensitivity) extrafusal fibers conteatcle innervated by alpha effernt fibers of large A neruon

Question 31

operation fo msucle spindle

Answer 31

extranal vs internal stretcj

Question 32

alpha-gamma co-activation

Question 33

stretch relfexes

Answer 33

brain sets msuelces length this way. example s knee-jerk reflex

Question 34

knee-jerk reflex (be able to expan the patheway)

Question 35

tendon relfexs

Answer 35

prevent danage due to excessive strecth onset and termiantion fo mucle contratcion. prodces musle relaxation in repsone to tension

Question 36

recriprocal activety in tendon strtech

Answer 36

contracting msule relaxes, antagonist contractions, into straight to cerebllum

Question 37

tenson vs stretch reflex explain

Question 38

tendon organ

Question 39

the flexor (withdrawl) relfex

Answer 39

by painful stimuli - automatic withdral of threatend body part. sitting still for a painful needle in the hsoptisla, brain overrides

Question 40

crossed-extensor relfex

Answer 40

flexor reflexses in weigth bearing limbs for abalnce. ipsilateral withdrawy reflex and contralateral extsor relfex

Question 41

compare and describe all the reflexes

Question 42

superficail reflexes

Answer 42

plantar and abdominal relfex
