The two parts that make up the nervous system are the brain and the spinal cord.
The three types of neurones are sensory, inter and motor.
Informations travels through a nerve cell through the receptors, then the CNS, then the effectors.
The nerve pathway followed by a reflex action is called a reflex arc. For example, a simple reflex arc happens if we accidentally touch something hot.
Reflex action: Stimulus, receptor, sensory neurone, inter neurone, motor neurone, effector, response.
Hypothalamus detects and controls functions such as temperature regulation, thirst, hunger, sleep etc. and the release of other hormones within the body.
Homeostasis is the maintenance of stable body conditions.
For the body to warm up, it begins to shiver, and hair on skin stand up.
For your body to cool down, hairs stay flat and skin goes red.
