Question

Injury to the hypothalamus may result in all of the following EXCEPT ________.

A) loss of fine motor control
B) loss of body temperature control
C) sleep disturbances
D) dehydration

Answer 1

The hypothalamus is involved in endocrine and autonomic functions but not in fine motor control, which is managed by other parts of the brain like the cerebellum and motor cortex.

Step-by-step explanation:

Injury to the hypothalamus may result in several physiological changes, but it does not typically cause a loss of fine motor control. The hypothalamus is a critical brain structure that plays an essential role in regulating many aspects of endocrine and autonomic functions. This includes body temperature regulation, sleep cycles, thirst, and hunger, amongst other things. Therefore, injury to the hypothalamus could lead to issues such as loss of body temperature control, sleep disturbances, and dehydration. However, fine motor control is primarily coordinated by the cerebellum and the motor cortex, rather than the hypothalamus.
