Which type of reflex arc affects muscles?
Correct answer: B. Somatic reflex arc
- A. Autonomic reflex arc
- B. Somatic reflex arc
- C. Both A and B
- D. None of these
Explanation
In order to solve such questions, the candidate first must know the difference between Somatic and Autonomic. Somatic responses involve those that can be controlled, whereas autonomic responses include those that are autonomous and involuntary. There are two types of Reflex arcs: 1. Autonomic reflex arc, which has its impact on the internal organs of the body, such as the Heart, kidney, ureter, etc 2. Somatic reflexes are which have's impact on skeletal muscles that are voluntary in action. Thus, option 'B' is correct.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
