Morgarella [4.7K]

Correct question:

The hypothalamus __________.

a) influences the function of only one lobe of the pituitary gland.

b) synthesizes all of the hormones produced by the pituitary gland.

c) regulates both reproduction and body temperature.

d) produces only inhibitory hormones.

Answer:

C) Regulates both reproduction and body temperature.

Explanation:

The hypothalamus is a small but important area in the center of the brain. It plays an important role in hormone production and helps to stimulate many important processes in the body and is located in the brain, between the pituitary gland and thalamus.

The hypothalamus’ main role is to keep the body in homeostasis as much as possible.

Homeostasis means a healthful, balanced bodily state.

The hypothalamus acts as the link between the endocrine and nervous systems to achieve this. It plays a part in many essential functions of the body such as: body temperature, thirst, appetite and weight control, emotions, sex drive, blood pressure and heart rate, production of digestive juices and balancing bodily fluids.
