Answer #1

Function of primary motor cortex:

  • Control the voluntary movement.
  • Responsible for execution of movement.
  • It get information from the thalamus and it provides action to the information.

Function of premotor cortex:

  • It is located in front of the primary motor cortex.
  • It controls the proximal muscles and axial muscles present in the body and execute the movement in response to stimulus.
  • Controlling the motor skills of repetitive and patterned nature.

Function of somatosensory cortex:

  • Somatic sensation in the body,visual stimuli and movement planning.
  • Located on postcentral gyrus.

Function of associative areas:

  • It act as a connection between sensory and motor areas.
  • Receive sensory stimuli from auditory,visual and gustatory,send information to the cortex.
  • Planning motor function and the action proceeds.

The bulk of brain myelination takes place from two months prenatally to two months after birth. However, brain myelination continues until well into the second decade of life in some areas of the cerebral cortex. The first 3 cortical regions to myelinate are the motor cortex, the olfactory cortex and the somatosensory cortex. What are the last 3 cortical areas to fully myelinate? describe their functions in detail.
