Question

Which part of the brain is responsible for thermoregulation?
A. Cerebrum
B. Hypothalamus
C. Corpus callosum
D. Medulla oblongata

Answer 1

Hint:The forebrain plays a vital role in the retrieval of information connected to complex cognitive tasks, voluntary, and sensory and associative functions. It is divided into three regions.

Complete answer:
The brain is our body's central information processing organ. It controls voluntary movements, body coordination, the working of essential internal organs, thermoregulation, various endocrine gland functions, hunger and thirst, and human behaviour. It is also a place where vision, sight, voice, memory, intellect, feelings and thoughts are processed. The brain is divided into three regions- forebrain, midbrain, and hindbrain.

The forebrain is made up of hypothalamus, thalamus and cerebrum. The cerebrum is the main component of the human brain. A deep cleft separates the cerebrum lengthwise into two parts, referred to as the left and right cerebral hemispheres. The left side of the brain is connected to the right side by the corpus callosum. The connection allows information to be exchanged between the two halves. The cerebrum coils around a structure called thalamus, which is a major coordination area for sensory and motor signals.

The hypothalamus is at the base of the thalamus. Hypothalamus includes a variety of centres that regulate body temperature, and compulsion to eat and drink. It also includes many groups of neurosecretory cells that secrete hypothalamic hormones.

The medulla is connected to the spinal cord. The medulla contains centres for respiration control, reflexes of the circulatory system, and gastric secretions.

Therefore, the correct answer is option B i.e., Hypothalamus.

Note:Hypothalamus is involved in several functions of the autonomic nervous system, since it gathers input from virtually all areas of the nervous system. Therefore, it is regarded as the connection between the nervous system and the endocrine system.
