Question

question 18 (1 point) the ____ division of the nervous system tends to prepare the body for action. parasympathetic sympathetic motor afferent somatic motor question 19 (1 point) about 90% of the neurons in the nervous system are ____. motor neurons interneurons sensory neurons

Explanation:

For Question 18, the sympathetic division of the nervous system activates the body's "fight - or - flight" response, preparing it for action. The parasympathetic division is for rest and digestion. Motor afferent is not a correct term in this context (afferent is for sensory input and motor is for output). Somatic motor is related to voluntary muscle movement but not specifically about preparing the body for action like the sympathetic division.
For Question 19, interneurons are the most numerous in the nervous system, accounting for about 90% of neurons. They are found in the central nervous system and are involved in processing and integrating information. Motor neurons carry signals from the central nervous system to muscles and glands, and sensory neurons carry information from sensory receptors to the central nervous system.

Answer:

Question 18: B. sympathetic
Question 19: B. interneurons
