Question

describe three sensory and motor areas of the brain and explain how each is related to a specific emerging infant capacity

Answer 1

Brain is broadly divided into three parts, namely

Cerebrum- largest part of the brain which is related to memory, intelligence, thinking , sensory and motor areas.

Cerebellum- circular part of brain situated little posteriorly is related to the body balance and equilibrium.

Medulla oblongata- found at the base of the brain which which handles all the involuntary actions such as respiration, circulation, digestion.

The three sensory and motor areas of the brain are as follows.

The cerebrum cortex includes these areas.

SENSORY AREAS of brain include the primary auditory cortex, primary somatosensory cortex and primary visual cortex.

MOTOR AREAS - the cerebrum is divided into the left and right hemisphere which is controlled in the opposite direction, that means , the left side of the body will be controlled with the right hemisphere and the right side of the body is controlled by the left hemisphere.

Primary auditory cortex controls the hearing by possessing sound waves.

Primary somatosensory cortex controls sense of touch or pressure.

Primary visual cortex helps in vision which is highly specialized for vision of moving objects also.

All these sensory impluses are carried to the brain and brain sends signals back through the motor neurons which help in movement or response of the stimulus.
