Where is the vasomotor center located in the human body?
A
In the medulla oblongata
B
In the cerebellum
C
In the thalamus
D
In the hypothalamus
Verified step by step guidance1
Understand the role of the vasomotor center: It is responsible for regulating blood vessel diameter and blood pressure.
Identify the location of the medulla oblongata: It is part of the brainstem, located between the pons and the spinal cord.
Recognize the function of the medulla oblongata: It controls autonomic functions such as heart rate, breathing, and blood pressure.
Differentiate the medulla oblongata from other brain structures: The cerebellum is involved in motor control, the thalamus acts as a relay station for sensory information, and the hypothalamus regulates homeostasis.
Conclude that the vasomotor center is located in the medulla oblongata, as it is involved in autonomic control of cardiovascular functions.
