Which of the following types and functions of the neuron is correct?
Correct answer: A. Sensory neurons carry impulses from sensory receptors to the CNS; interneurons relay signals within the CNS; motor neurons transmit impulses from the CNS to muscles or glands
- A. Sensory neurons carry impulses from sensory receptors to the CNS; interneurons relay signals within the CNS; motor neurons transmit impulses from the CNS to muscles or glands
- B. Motor neurons carry sensory impulses to the CNS; interneurons transmit impulses to muscles; sensory neurons relay signals within the CNS
- C. Interneurons carry impulses from effectors to the CNS; sensory neurons transmit impulses from the CNS to interneurons; motor neurons pass signals within the CNS
- D. Sensory neurons transmit impulses from the CNS to effectors; motor neurons carry sensory information to the CNS; interneurons connect sensory to motor neurons outside the CNS
Explanation
Sensory neurons function to carry the sensory information to the CNS. Interneurons transfer impulses from sensory to motor neurons, remaining within the CNS. Motor neurons are neurons that transmit impulses fromthe CNS to the effectors.

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.
