Sensory System
Our sense organs detect information and send electrical signals to the brain.The brain interprets the signals and then decides how to react to the stimulus.

The senses
TOUCH
TASTE
Sight
copy
Sight
Light passes through the cornea and enters the eye through the pupil.
ORGAN: Eyes
PROCESS:
The iris controls the size of the pupil and the amount of light that enters the eye.
The lens focuses the light on the retina.
The retina sends electrical signals to the optic nerve. From there, the signals are carried to the brain.
Hearing
copy
Hearing
ORGAN: Ears
Sound waves enter the outer ear. They go into the auditory canal and they make the eardrum vibrate.
PROCESS:
The cochlea detects sound vibrations in the ossicles (three small bones) and it produces electrical signals.
The auditory nerve carries the electrical signal to the brain.
Smell
copy
Smell
ORGAN: Nose
Chemical particles in the air enter the nose through the nostrils.
PROCESS:
The chemical particles are detected by nerve receptors inside the nose.
The nerve receptors send electrical signals to the olfactory bulb in the brain.
Taste
copy
Taste
ORGAN: Tongue
Food touches the tongue, wich is covered with taste buds.
PROCESS:
The taste buds have receptor cells that detect tastes.
Electrical signals are carried to the brain by gustatory nerves.
Touch
copy
Touch
ORGAN: Skin
The skin covers and protects your body. The top layer is the epidermis and the middle layer is the dermis.
PROCESS:
The dermis contains nerves. These nerves detect heat, pressure and texture.
The nerves send electrical signals to the brain.

Types of neurons
The peripheral nervous system is made up of nerves.
These nerves are made up of tiny cells called neurons that transmits electrical signals.

The signals from the brain travel through the nervous system to our muscles and they move our bones and joints. All these parts together form the locomotor system.

The skeleton has 206 bones that are connected by joints.
Bones
Joints
Short bones provide stability and support.
Fixed: Do not move
Long bones are found in arms and legs.
Semi-flexible: Allow some movement.
Flat bones protect our internal organs.
Flexible: Allow much more movement.

In this unit we are not going to learn all of them!
Muscles
copy
The human body has more than 600 muscles. The nervous system controls these muscles. There are three types of muscles.
Skeletal muscles are joined to bones by tendoms. They are voluntary muscles, we can control them.
Smooth muscles are found in organs like the stomach. They are involuntary muscles.
Cardiac muscles make the heart move and beat. They are involuntary muscles.
