Question

The appetite and satiety centers in brain are located in region of
a. Hypothalamus
b. Cerebral hemisphere
c. Medulla oblongata
d. Cerebellum

Answer 1

Hint: The lateral part of the hypothalamus is responsible for the control of food intake. Stimulation of this region of hypothalamus creates the feeling of hunger and controls the appetite and satiety of an organism.

Complete answer:
The hypothalamus is the part of the brain that contains a number of small nuclei with a variety of functions. One of the most important functions is to link the nervous system to the endocrine system via the pituitary gland. It is located below the thalamus and is part of the limbic system. All vertebrates’ brains contain a hypothalamus. In humans it has the size of an almond.
The hypothalamus is responsible for the regulation of certain metabolic processes and other activities of the autonomic nervous system. The hypothalamic secretions inhibit or stimulate the secretions of the pituitary gland. The hypothalamus controls body temperature, hunger, attachment behaviors, thirst fatigue, sleep and circadian rhythms.
Cerebral hemisphere is the part of the brain that controls the muscle functions and also controls the speech, thought, emotions, reading, writing and learning. The right hemisphere controls the muscle functioning of the left part of the body and vice versa.
The medulla oblongata is the lower half of the brain stem that connects the brain to the spinal cord. It is responsible for regulating basic functions of the autonomic nervous system like respiration, cardiac function and reflexes like vomiting, coughing, sneezing and swallowing.
The last one i.e. cerebellum is located behind the top part of the brain stem. It also possesses two hemispheres. It receives the information from sensory systems and regulates the motor movements. It coordinates the voluntary movements such as posture, balance, coordination resulting in smooth and balanced muscular activity.

Note: Movement is essential to the survival of every living thing. In order to serve this purpose the movement must be well coordinated. This coordination can only be achieved through the proper working of all the parts of the neural system i.e. brain and other accessory organs.
