Question 5

do muscle spindles generate useful force

Answer 5

no

Question 6

what is wrapped about muscle spindles for muscle stretch detection

Answer 6

sensory axons

Question 7

gamma motor neurones cause active

400

Question 11

what are the 2 types of endings for spindles

Answer 11

primary and secondary

Question 12

what is a primary ending spindle

Answer 12

signal position and velocity - transmitted via 1a afferents - sensitive to vibrations

Question 13

what is the secondary muscle ending spindle

Answer 13

position only via group 2 afferents -

Question 14

what are gamma fibres

Answer 14

contractile element of spindle - no useful force - just keep spindle taught

Question 15

main muscle with alpha neurons causes muscles to

Answer 15

slacken - dropping firing rate and lose sensitivity

Question 16

gamma activation contracts spindle which maintains

Answer 16

sensitivity

Question 17

muscle vibration causes

Answer 17

illusions of muscle stretch - position and velocity

Answer 18

continuously

Answer 21

records tension

Question 22

when does a golgi tendon stretch

Answer 22

when a muscle contracts

Question 23

1b afferent axons becomes compressed by collagen fibres and its rate of fire..

Answer 23

increases
