NEET PG Medical – 2019 – Question – 16
Golgi tendon organ responsible for?
a) Tension
b) Length
c) Pressure
d) Proprioception
Show Answer
Correct Answer – A
Ans: A. Tension.
Difference between functions of muscle spindle & golgi tendon organ:
Muscle spindle:
- Acts as “Muscle length detectors”.
- Also detects rate of change in muscle length.
Golgi tendon organ:
- Acts as “Muscle tension detectors”.
- Also detects rate of change in muscle tension.
- Because of location of muscle spindle & golgi tendon organ.
- Muscle spindle are parallel to muscle fibers (extrafusal fibers).
- Golgi tendon organ in series to muscle fibers (extrafusal fibers).
Yet, Both are activated by muscle stretch.
