Answer to Question 1

A
The reticular activating system, located in the brainstem, controls consciousness and alertness. The cerebellum maintains muscle tone, coordinates muscle movement, and controls balance. The thalamus is a relay system for sensory stimuli. The hypothalamus controls body temperature.

Answer to Question 2

B
Photoreceptors located in the retina of the eyes detect visible light. Proprioceptors in the skin, muscles, tendons, ligaments, and joint capsules coordinate input to enable an individual to sense the position of the body in space. Chemoreceptors are located in the taste buds and epithelium of the nasal cavity. They play a role in taste and smell. Thermoreceptors in the skin detect variations in temperature. Mechanoreceptors in the skin and hair follicles detect touch, pressure, and vibration.
