Functions of sensory receptors

Question 1

Slow prolonged stretch is synonymous with what response?

Answer 1

static response

Question 2

Sudden stretch is synonymous with what type of response?

Answer 2

dynamic response

Question 3

T/F In slow stretch, only primary sensory endings fire continuously and in proportion to the degree of stretch

Answer 3

False. Both primary and secondary sensory endings fire continuously and in proportion to the degree of stretch

Question 4

T/F Gamma static motor fibers fire steadily, regardless of muscle stretch.

Answer 4

False. Gamma-static motor fibers fire proportionately to the increase or decrease in stretch

Question 5

T/F In sudden stretch, only primary sensory endings fire.

Answer 5

True.

Question 6

T/F In sudden stretch, primary sensory endings only fire while change in length is occurring.

Answer 6

True.

Question 7

How do Gamma-dynamic motor fibers maintain receptor sensitivity?

Answer 7

They fire to maintain spindle fiber length proportions

Question 8

Where would a golgi tendon organ be found?

Answer 8

the myotendinous junction

Question 9

What is the name of a small bundle of tendon collagen fibers connecting muscle fibers to tendon fibers?

Answer 9

Tendon organ (golgi tendon organ)

Question 10

What type of sensory fiber wraps around the tendon organ?

Answer 10

Type Ib sensory fiber

Question 11

T/F Multiple Type Ib sensory fibers wrap around each tendon organ

Answer 11

False. Only one fiber per organ

Question 12

T/F Tendon organs fire to create tension in the organ

Answer 12

False. Tendon organs fire in response to tension in the organ from muscle contraction or stretch

Question 13

Tendon organs have what type of response level(s)?

Answer 13

Dynamic and static response
