SENSORV SVSTEMS

Tactile system

The tactile system refers to the awareness of touch through receptors in the skin.
It consists of two levels: the first is discrimination to teli us where the touch is on our body, and a second level to teli us whether it is a safe or dangerous touch.

Visual system

The visual system interprets what we see. lt recognizes shapes, colours, letters, words and numbers. It iis also important in reading body language and other non-verbal clues during social interactions. Vision guides our movements and we continually check out actions with our eyes to make sure we move around safely.1

Auditory system

We use our auditory system to identify the quality and direction of sound.
lt not only hears sound, it also helps us to understand speech .

Gustatory and olfactory systems

Taste and smell are very closely linked senses and work as one integrated system. The sense of smell is one of the oldest and most vital parts of the brain. The two senses together allow us to identify food that we enjoy, and also teli us what is safe to eat.

It allows us to know where the [Qges of our body are, how far away we are from a wall, or how much pressUTe we are exerting on a pencil.
