The human nervous system incorporates which of the following principal anatomical components?
Show answer Hide answer
Answer: C. brain, spinal cord and neurons
Explanation
The human nervous system coordinates all bodily activities and responses. It consists of the brain, spinal cord, and extensive peripheral neurons. These interconnected components process electrical signals throughout the body. Neurons transmit electrochemical impulses across synapses to communicate signals. The central nervous system integrates sensory data and commands motor actions. Peripheral nerves connect internal organs and muscles to the central processing units.
Neurologists diagnose disorders affecting the central and peripheral nervous systems. Reflex actions bypass the brain to initiate rapid protective muscle responses. Medical imaging techniques visualize neural pathways to detect neurological damage. The brain alone lacks the spinal cord and peripheral neuron connections. The brain and backbone option omits the crucial network of peripheral neurons. None is incorrect because comprehensive anatomical components are specified.
