Stretch Reflex

Question 1

Muscle spindles

Answer 1

activates neurons in anterior horn of spinal column, produces brief muscle contraction, sensitive to stretch

Question 2

Golgi tendon organ

Answer 2

inhibit motor neurons in anterior horn of spinal column, slower transmission than muscle spindles, sensitive to tension

Question 3

With injury, what can the muscle spindle and Golgi tendon organ limit?

Answer 3

ROM

Question 4

Deep tendon reflexes

Answer 4

Patellar tendon, achilles tendon, biceps brachii tendon, brachioradialis tendon, triceps brachii tendon

Question 5

Patellar tendon

Answer 5

L4, dull side of hammer just above tibial tuberosity, will see knee extension

Question 6

Achilles tendon

Answer 6

S1 and S2, dull side of hammer right on achilles tendon, will see some plantarflexion

Question 7

Biceps brachii tendon

Answer 7

C5, place thumb right on the biceps brachii tendon (crook of arm) and hit hammer on triangle side

Question 8

Brachioradialis tendon

Answer 8

C6, use dull side of hammer 3 inches above scaphoid on thumb, will see some radial deviation

Question 9

Triceps brachii tendon

Answer 9

C7, use dull side of hammer on posterior side of elbow (right above knob)
