Question

The region in the brain portion that controls hunger is
(a) Medulla
(b) Hypothalamus
(c) Cerebrum
(d) Midbrain

Answer 1

Hint: The brain is the largest organ of the human body with the most complex structure containing a hundred billion nerves that communicate in connections called synapses. It is made up of soft tissue and contains nerve cells and blood vessels with grey and white matter in it. It has a huge amount of water content and fat content.

Complete step by step answer:
The hypothalamus is the region of the brain that helps in controlling hunger. Hypothalamus is associated with the endocrine system as it is responsible for maintaining the body's internal balance known as homeostasis. Hypothalamus receives information from the nervous system, so it serves as the link between the nervous system and the endocrine system. Hypothalamus is almost about the size of an almond.

Additional information:
Medulla: The lowest part of the brain which is connected by the pons to the midbrain. It has a crucial role in transmitting signals between the spinal cord and the highest parts of the brain. It controls autonomic activities like heartbeat and respiration. Medulla consists of both types of nerves a.r.e. myelinated and unmyelinated. Neurons transmit motor and sensory impulses, control the movement of somatic sensory information from internal organs, and control of sleep and arousal. The middle part of the medulla is affected by any injury or disease that can cause medial medullary syndrome which is partial paralysis of the opposite side of the body.
Cerebrum: The uppermost and largest part of the brain which consists of cerebral hemispheres is a cerebrum. The two-third weight of the brain is of the cerebrum. One hemisphere controls language and speech whereas others interpret visual and spatial information. The hemisphere which controls language is functionally dominant over the other. If the cerebrum is affected by the stroke it will affect the functions of the human body such as movement and sensation, speech and language, and eating in swelling.
Midbrain: The topmost of the brain which connects the brain and spinal cord. It is divided into three parts i.e. the colliculi, the tegmentum, and the cerebral peduncles. It is a part of the central nervous system. It controls sleep and wake cycles, arousal, and temperature regulation. It plays a vital role in the motor movement specifically the movements of the eye and auditory and visual processing.
So, the correct answer is 'hypothalamus'.

Note: The brain of an adult weighs about 3 pounds. 75% of the brain consists of water. Headaches can be caused because of chemical reactions in the brain and multitasking is not possible in the brain. Among all the vertebrates, human beings are the largest. 2% of the whole-body weight is by the brain. The brain gets 20% off of the total blood and oxygen produced in our body. The brain generates 23 watts of power when we are awake and it produces enough electricity to power a lightbulb.
