The primary function of spinal cord is to:
Correct answer: D. Communicate brain with rest of body
- A. Produce CSF
- B. Produce hormones
- C. Communicate two hemispheres
- D. Communicate brain with rest of body
Explanation
Option D is correct.The spinal cord functions primarily in the transmission of nerve signals from the motor cortex to the body, and from the afferent fibers of the sensory neurons to the sensory cortex. It is also a center for communication between body and brain. The primary function of the spinal cord is to communicate the brain with the rest of the body. The spinal cord is a long, thin, cylindrical structure that extends from the brainstem to the lower back. It is made up of nerves that carry information between the brain and the body.

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.
