Solution

The correct option is D

Medulla oblongata


The medulla oblongata is the part of the brain which contains a cardiac centre, respiratory centre and vomiting centre. The cerebrum is the principal and most anterior part of the brain in vertebrates, located in the front area of the skull and consisting of two hemispheres, left and right, separated by a fissure. It is responsible for the integration of complex sensory and neural functions and the initiation and coordination of voluntary activity in the body. The spinal cord is a long, thin, tubular bundle of nervous tissue and support cells that extend from the medulla oblongata in the brainstem to the lumbar region of the vertebral column. The brain and spinal cord together make up the central nervous system.The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as speech, posture, balance, and coordination resulting in smooth and balanced muscular activity.
