Sensitivity of the Body

All living things perform seven life processes; Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion and Nutrition. Each system of the body has a specific role in each of these actions. In this article we shall discuss sensitivity.

The system directly involved in sensitivity is the Nervous system. The nervous system is not one specific system. It includes both the central nervous system and the peripheral nervous system. The central nervous system is located within the brain and spinal cord. The peripheral nervous system is stretched throughout the remainder of the body, connecting the central nervous system to the all of our limbs and organs.

Sensitivity in the body covers a wide range of senses; sight, taste, touch, hearing and smell. There are five sense organs in the human body which can be associated with senses known as sensory organs. These five sensory organs each have receptors for the specific stimuli which link to the parts of the nervous system (sensory systems) and by extension, the brain. In addition to these five senses there are a number of other senses that require the use of multiple sensory organs such as pressure or awareness of balance.
