Question

What fine-tuned sensory receptors detect differences in tension generated by active muscle rather than muscle length

Answer 1

golgi tendon organs fine-tuned sensory receptors detect differences in tension generated by active muscle rather than muscle length.

• Gamma motor neurons fire to regain sensitivity, causing the spindle to contract, becoming taut and regaining the ability to transmit muscle length.
• There are two groups of motor neurons. Extrafusal fibers, the rapidly contracting fibers that give the muscle its power, are innervated by alpha motor neurons.

What is golgi tendon organs?

• The Golgi tendon organ, which is located close to the point where a tendon joins a muscle, is a sensory ending that resembles a tree and is encased in a spindle-shaped connective tissue capsule.
• In a male, one tendon organ is attached to 10 to 20 muscle fibers.
• An endpoint of a typical tendon organ in limb muscles is roughly 0.5 mm long.
