Question

Which part of the mammalian brain controls muscular coordination?
A. Cerebrum
B. Medulla oblongata
C. Cerebellum
D. Corpus callosum.

Answer 1

Hint:Brain is the center of control and coordination, which controls all activity of the body either voluntary or involuntary in action. Neurons are the structural and functional unit of the brain that carry information from one neuron to the next neuron via electrical impulse.

Complete answer:
Mammalian brain is present in the cranial cavity, that cavity is enclosed bone. The brain is covered by three layers called meninges and cerebrospinal fluid which protect the brain from shock.
A. Cerebrum is a larger part of the brain that is divided into two hemispheres by a central fissure. It forms the forebrain region of the brain. This part of the brain is responsible for receiving and giving information from the sensory organs and also controls the body.
B. Medulla oblongata:- It is the part of the hindbrain that appears as a long stem-like structure and is partially inferior to the cerebellum part of the brain. It controls the involuntary action of the body such as sneezing, vomiting, respiration, cardiac function, vasodilation, swallowing, and coughing.
C. Cerebellum:- it is the second-largest part of the brain and forms the hindbrain. It is located behind the cerebrum and near the brain stem. This part of the brain is responsible for muscular motor functions such as balancing, coordination, equilibrium, and maintaining body posture.
D. Corpus callosum:- it is the tract of white matter which links the two hemispheres of the brain functions to maintain the communication between both parts of the hemisphere.
Hence, the correct option is C.

Note: Mammalian brain is divided into three-part such as forebrain (cerebrum, thalamus, and hypothalamus), Midbrain ( cerebral aqueduct, corpora quadrigemina), and Hindbrain ( Pons, cerebellum, and medulla).
