Our Senses and Nervous System

Stimuli : a stimulus is any change that takes place around us that our sense notice.

Five senses: the five main senses are: touch, sigth, hearing, taste and smell. These senses allow us to interpret what is happening around us.

tem

Touch : we use our sense of touch to interpret information about texture,temperature, pain or pressure. Our skin covers and protects our body. It contains specialised receptors that respond to stimuli.

Sight : Our sense of sight lets us see the world around us. We can see objects and identify their shape, colour and size because of our sense of sigth. Light is essential in this procces . The sensory organs that we use for seeing things are our eyes.

Hearing: We hear the sounds around us thanks to our sense of hearing. Hearing occurs when our ears detect and process sound.

Taste: The tongue is the resposible for our sense of taste. The taste receptors in our tongue detect flavours in food. The basic flavours are: sweet, salty, sour and bitter.

Smell: the nose, which we use to interpret smeels, is responsible for our sense of smell. There are hundres of different types of olfatory receptors, each desinned to detect certain smells.

The nervous system transmits signals to difeferents parts of our bodies to coordinate our voluntary and invonluntary actions.

These actions respond to stimuli around us and to stimuli from inside our bodies (like feeling hungry or thisty).

The nervous system has two main parts: the central nervous system and the nerves.

The nervious system consists of specialed cell called nervous.

The nervous system is responsible fot two types of actions: voluntary: (those that we choose to do) and involuntary (these actions that our bodies perform but wich we have no control over).
