A nerve controlling the contraction of the left biceps brachii muscle would be classified as a part of:
Correct answer: D. Somatic division of the peripheral nervous system
- A. Spinal cord
- B. A ganglion
- C. Central nervous system
- D. Somatic division of the peripheral nervous system
Explanation
The somatic division of the peripheral nervous system carries signals voluntarily controlled by the brain to skeletal muscles for movement. Since the biceps brachii is a skeletal muscle responsible for flexing the elbow, a nerve controlling its contraction would be part of this division.

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.
