Which part of the brain is responsible for thermoregulation?

A. Cerebrum

B. Hypothalamus

C. Corpus callosum

D. Medulla oblongata

The brain is the body’s central information-processing organ. It regulates voluntary movements, body coordination, vital internal organ functions, thermoregulation, endocrine gland activities, hunger, thirst, and behavior. It is also the center for vision, hearing, speech, memory, emotions, intellect, and thought processes.

The brain is structurally divided into three major regions: forebrain, midbrain, and hindbrain.

Forebrain

The forebrain consists of the cerebrum, thalamus, and hypothalamus.

• The cerebrum is the largest part of the human brain. A deep cleft divides it into the left and right cerebral hemispheres, connected by the corpus callosum, which enables communication between the two halves.
• The thalamus acts as a major coordination center for sensory and motor signals.
• The hypothalamus, located at the base of the thalamus, regulates body temperature, hunger, thirst, and other essential drives. It also contains neurosecretory cells that release hypothalamic hormones.

Hindbrain

The medulla, part of the hindbrain, connects the brain to the spinal cord. It controls vital functions such as respiration, reflex actions of the circulatory system, and gastric secretions.

Correct Answer: Option B - Hypothalamus
