Answer:
A. The hypothalamus sends the needed hormone to the body.
B. The hypothalamus sends a messenger hormone to the pituitary gland.
C. The hypothalamus determines which area of the brain it activates.
Step-by-step explanation:
What is the Hypothalamus?
The hypothalamus, which is a structure deep within the brain, serves as the body's intelligent control and coordination center. Its primary duty is to maintain the body in a steady state known as homeostasis. It accomplishes this by either directly altering the autonomic nervous system or controlling hormones.
Answer Breakdown
- Choice A is the best answer. The hypothalamus is the gland in the body that is responsible for homeostasis. Therefore, the hypothalamus will produce the necessary hormone the body needs to retain homeostasis.
- Choice B is not the best answer. Depending on the body's exact response, the hypothalamus may send a messenger hormone to the pituitary gland. However, the hypothalamus is generally responsible.
- Choice C is incorrect. The hypothalamus can transmit hormones that may go to the brain or interact with neurotransmitters in the brain but it does not "activate a portion of the brain" to maintain homeostasis.
