The vasomotor center of the reticular formation does which of the following?
A
Controls voluntary muscle movements
B
Regulates blood vessel diameter
C
Processes sensory information
D
Coordinates balance and posture
Verified step by step guidance
1
Understand the role of the vasomotor center: The vasomotor center is a part of the reticular formation located in the medulla oblongata of the brainstem. Its primary function is to regulate blood vessel diameter, which in turn affects blood pressure.
Identify the options given in the problem: The options are 'Controls voluntary muscle movements', 'Regulates blood vessel diameter', 'Processes sensory information', and 'Coordinates balance and posture'.
Evaluate each option based on the function of the vasomotor center: The vasomotor center does not control voluntary muscle movements, process sensory information, or coordinate balance and posture. These functions are associated with other parts of the brain.
Focus on the correct function: The vasomotor center is responsible for regulating blood vessel diameter, which is crucial for maintaining blood pressure and ensuring adequate blood flow throughout the body.
Conclude with the correct answer: Based on the understanding of the vasomotor center's role, the correct answer is 'Regulates blood vessel diameter'.
