- Sense of smell (nose/chemical in air)
- Sense of taste (tongue/chemical in food)
- Sense of hearing (ear)
- Sense of sight (eye)
- Sense of touch (skin)
Stimuli------Receptors in sensory organ--(nerve impluses)--nerve------Brain|
Response------Effectors(muscles, glands)--(nerve impluse)--nerve
The receptors in sensory organ produces nerve impluse. then it's send to the brain to interprets and that's how u response!Effectors are part of your body like muscles.
Now let's enter chapter 1.2(Touch)
The skin is the largest organ in the body. It detect temperature, pain, touch and pressure.
It has two main layers the outer epidermis and inner dermis.
fatty layer.There are also blood vessel, nerve, gland and more.
5 type of receptors in it which is preassure, heat, cold, pain and touch.The sensitivity of your skin also depends on the deepness of your receptors from the skin and how close together there are.
Our nose not just help us breathing but smelling.
Nostril and the hollow space is called the Nasal cavity. The receptors for the nose is located on the celling of the Nasal cavity. There is also mucous lining in the Nasal cavity which function is moistens the air before entering the lung.
dissolving the chemical in air to stimulate the receptors.But after smelling something to long, the receptors stop sending nerve impluse (electrical messages) to the brain.
