clonus

Question 2

What is the main receptor that detects stretch in a muscle?

Answer 2

Muscle spindle

Question 3

What does the Golgi Tendon Organ (GTO) primarily detect?

Answer 3

Excessive tension (force) in the muscle tendon

Question 4

What is the main result of an Upper Motor Neuron (UMN) lesion on reflexes?

Answer 4

Hyperreflexia (overactive reflexes)

Question 5

Why does clonus occur after a UMN lesion?

Answer 5

Loss of inhibition causes the stretch reflex arc to become hyperexcitable and oscillate

Question 6

In a UMN lesion

Answer 6

is the signal from the Golgi Tendon Organ (GTO) completely gone?

Question 7

What is the role of descending pathways from the brain in normal reflex control?

Answer 7

They provide inhibitory control to prevent hyperreflexia

Question 8

During clonus

Answer 8

which mechanism is being overpowered?

Question 9

What is the key difference in what muscle spindles detect vs. what GTOs detect?

Answer 9

Spindles detect stretch (length change)

Question 10

What type of stimulus primarily activates the Muscle Spindle?

Answer 10

A quick

Question 11

What type of stimulus primarily activates the Golgi Tendon Organ (GTO)?

Answer 11

Strong

Question 12

What is the primary function of the Muscle Spindle?

Answer 12

To detect changes in muscle length and speed

Question 13

What is the primary function of the Golgi Tendon Organ (GTO)?

Answer 13

To detect excessive tension

Question 14

What happens when you hold a muscle under strong

Answer 14

sustained stretch?

Question 15

How does a doctor’s reflex hammer tap work?

Answer 15

It provides a quick stretch that activates muscle spindles, not GTOs.

Question 16

How do athletes and physical therapists use the GTO response?

Answer 16

They use prolonged stretching to activate GTOs, inhibiting spindles to increase flexibility.

Question 17

In a reflex test

Answer 17

which receptor is the main target: Spindle or GTO?

Question 18

Which receptor acts as a “motion sensor” for muscle length change?

Answer 18

Muscle Spindle.

Question 19

Which receptor acts as a “load sensor” for muscle tension?

Answer 19

Golgi Tendon Organ (GTO).
