Question

multiple choice question

what is the result of a tendon reflex response?

contraction of the muscle
inhibition of the muscle

Explanation:

Define the tendon reflex mechanism

The tendon reflex (also known as the Golgi tendon reflex) is a protective feedback mechanism mediated by Spinal Reflexes and Reflex Arc Physiology. It monitors and regulates muscle tension to prevent excessive force that could damage tendons or muscles.

Identify the sensory receptor

The sensory receptors involved are Golgi tendon organs, which are located within tendons near the muscle-tendon junction. They detect increased tension when a muscle contracts strongly.

Trace the reflex pathway

When tension rises, sensory signals travel via afferent nerve fibers to the spinal cord. Within the spinal cord, these sensory neurons synapse with inhibitory interneurons.

Determine the motor response

The inhibitory interneurons release inhibitory neurotransmitters that suppress the alpha motor neurons innervating the contracting muscle. This leads to the relaxation or inhibition of the muscle, preventing injury.

Answer:

• Contraction of the muscle
• Inhibition of the muscle (Correct answer)
