Which part of the nervous system controls actions like walking and running?
Correct answer: A. Somatic nervous system
- A. Somatic nervous system
- B. Parasympathetic nervous system
- C. Sympathetic nervous system
- D. Peripheral nervous system
Explanation
The somatic nervous system (SNS) and the autonomic nervous system (ANS) are both parts of the peripheral nervous system. The SNS controls voluntary actions such as walking. The ANS is responsible for the control of vital functions such as heartbeat and breathing. It also gathers sensory information from the skin, joints, and muscles, like the sensation of touch or pain, and relays it to the brain for interpretation. The SNS consists of sensory (afferent) neurons, which transmit sensory information to the central nervous system (CNS), and motor (efferent) neurons, which carry commands from the CNS to the muscles.

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.
