Explanation:

Identify the first question

The first question asks: "What is the name for the orchestration of muscle contraction and relaxation that prevents muscles from working against each other?"
The options visible are:

• a. myotropic inhibition
• b. antagonistic inhibition
• c. reciprocal inhibition
• d. retroactive inhibition

Analyze the first question

When an agonist muscle contracts, its antagonist must relax to allow smooth movement. This neural mechanism is called reciprocal inhibition.

Identify the second question

The second question asks: "What is the name for the reflex response in a stabilizing leg contralateral to a leg with an injury?"
The accompanying diagram shows a person stepping on a sharp object (like a tack), withdrawing the injured foot (flexion reflex), while the opposite (contralateral) leg extends to support the body's weight.

Analyze the second question

This contralateral reflex that provides postural support during a withdrawal reflex is known as the crossed extensor reflex.

Answer:

Question 1

• a. myotropic inhibition
• b. antagonistic inhibition
• c. reciprocal inhibition (Correct answer)
• d. retroactive inhibition

Question 2

The reflex response in the stabilizing contralateral leg is the crossed extensor reflex.
