Which part of the brain is responsible for autonomic motor
functions such as respiration, blood pressure, and heart rate, as
well as for regulating muscle tone.
Multiple Choice
A. Sensory component of the reticular formation
B. Prefrontal cortex
C. Motor component of the reticular formation
D. Amygdala
E. Hypothalamus
Answer : C The motor component of the reticular
formation communicates with the spinal cord and is responsible for
regulating muscle tone (especially when the muscles are at rest).
The motor component of the reticular formation also assists in
autonomic motor functions, such as respiration, blood pressure, and
heart rate, by working with the autonomic centers in the medulla
and pons.
