What part of the brain initiates voluntary movement?
a. Parietal lobe
b. Hypothalamus
c. Cerebellum
d. Frontal lobe
ANS: D
The frontal lobes contain the motor areas that generate the impulses that bring about voluntary movement. Each motor area controls movement on the opposite side of the body. The parietal lobes contain the general sensory areas for the cutaneous senses, conscious muscle sense (proprioception), and taste (gustation). The hypothalamus has varied functions. The functions of the cerebellum are concerned with the involuntary aspects of voluntary movement: coordination, the appropriate direction and endpoint of movements, and the maintenance of posture and balance or equilibrium.
