Question

1. which body systems are involved in the reflex action shown in the diagram? a. the respiratory and excretory systems b. the excretory and muscular systems c. the muscular and nervous systems d. the nervous and digestive systems

Explanation:

Reflex actions involve the nervous system to transmit signals and the muscular system to produce movement. The sensory neuron detects the stimulus, the inter - neuron in the spinal cord processes it, and the motor neuron sends a signal to the muscle for the response. There is no direct involvement of the respiratory, excretory, or digestive systems in a simple reflex action like the one shown.

Answer:

C. the muscular and nervous systems
