Question

Different parts of the brain are associated with specific functions. Find the correct match regarding the part of the human brain which performs the following functions.
A. Sensation of feeling full – Hypothalamus
B. Vomiting – Medulla Oblongata
C. Picking up a pencil – Cerebellum
D. All of the above

Answer 1

Hint: Brain forms the central organ of the human body. Regulation of body temperature, water balance, and hunger are all under the control of the organ present in the brain which connects the link between the nervous system and endocrine system. It is considered the master of the autonomic nervous system

Complete answer:
The human brain is divided into three parts cerebrum, cerebellum, and brainstem which includes medulla oblongata and pons Varolii. A deep structure of the brain that contains a large number of nuclei is called the hypothalamus. The nervous system is connected to the endocrine system by the hypothalamus via the pituitary gland. Certain metabolic processes and activities of the autonomic nervous system are carried out by the hypothalamus. Hypothalamus is responsible for the various activities of the body. Hunger, sleep, thirst, the sensation of feeling full, and sexual response is under the control of the hypothalamus. The body temperature is under the control of the anterior hypothalamus. Therefore, option A is correct. A long stem-like structure called the medulla oblongata forms the upper part of the brain stem. It is a cone-shaped organ that regulates the involuntary functions of the body. The higher levels of the brain are connected to the spinal cord by the medulla oblongata. It plays an important role in the cardiovascular center, vasomotor center, and reflex actions which involve swallowing, coughing, and sneezing. So, option B is also correct. The cerebellum is the part of the brain that controls the voluntary movements of the body. It receives signals from the nervous system and other parts of the body and acts accordingly. Picking up a pencil is a voluntary movement. So, option C is also correct. Therefore, all of the options given above are correct.

So, option D is the correct answer.

Note: Motivated behaviors are controlled by the medial zone of the hypothalamus. The body temperature is under the control of the anterior hypothalamus. Damage to the hypothalamus can cause disruption in growth, body weight, sodium, water balance, and sleep cycles. Damage to the hypothalamus will also impact the endocrine system as well as the pituitary gland.
