Question

Write short note on the following: 

Neural coordination

Short Note

Solution

  • The neural system provides rapid coordination among the organs of the body.
  • This coordination is in the form of electric impulses and is quick and short-lived. All the physiological processes in the body are closely linked and dependent on each other.
  • For example, during exercise, our body requires more oxygen and food. Hence, the breathing rate increases automatically and the heart beats faster.
  • This leads to a faster supply of oxygenated blood to the muscles. Moreover, the cellular functions require regulation continuously. These functions are carried out by hormones.
  • Hence, the neural system, along with the endocrine system, controls and coordinates the physiological processes
