Question

In the given diagram of the brain what does "1" represent?

A. Pons
B. Midbrain
C. Cerebellum
D. Medulla oblongata

Answer 1

Hint:
The human brain regulates almost all aspects of the human body that range from physiological functions to cognitive abilities. It works by receiving and sending signals through neurons to various portions of the body. The human brain, just like most other mammals, has a similar basic structure, but it is better developed than any other mammalian brain.

Complete answer:
In the above diagram 1 represents the cerebellum.
The cerebellum is the second biggest portion of the brain, situated in the rear of the pons and medulla. The cerebrum and cerebellum are separated by a transverse fissure and cerebellar tentorium. The cortex is on the external surface of the cerebellum, and its parallel ridges are referred to as folia. Besides this, the cerebellum has cerebellar nuclei, cerebellar peduncles, and anterior and posterior lobes. The cerebellum is composed of two hemispheres, the external grey cortex, and the inner white medulla. It is primarily responsible for the coordination and maintenance of the body balance during running, walking, riding, swimming, and precision control of voluntary motions. The cerebellum senses equilibrium, coordinates eye movement, transfers information, and predicts the future location of the body during a certain movement. The cerebellum is also important for making fine adjustments to motor actions.

Option ‘C’ is correct

Note:
The brain is covered by the skull, which provides lateral, frontal, and dorsal protection. The skull is made up of 22 bones, 14 of which form the facial bones and the remaining 8 forms the cranial bones. Functionally, the brain is contained within the cranium and is encircled by cerebrospinal fluid.
