neurons have: 

-cell body: containing the nucleus, cell bodies from "grey matter" and are found at the periphery of the rain and the centre of the spinal cord
-dendron or dendrites carry impulses towarda the cell body.
-axon carry impulses away from the cell body.

kinds of nerves:

     a.Sensory: with sensory neurons that transmit impulsees from receptors                            towards the CNS
    b.Motor: with motot neurons that transmit impulses from the CNS to the                         effectors
    c.Mixed: containing both, sensory and motor neurons.

Homeostasis: It's the maintance of a Constant internal enviroment in the body. Eg. Constant temperature, water Balance, etc.

Nervous system: the nervous system collects information about changes Inside and outside the body, decides how the body should respond and controls That response.

            -brain: protected by the skull.

parts:  -spinal cord: protected by the Vertebral column

            -peripheral nervous system: nerves outside the Brain and the                                                                                                            Spinal cord

Neurons: the nervous system consist of a cast number of cells Called neurons, supported by a special type of connective tissue, neuroglia.

Neurons cannot divide and for survival they need oxygen And glucose.

Neurons have:  -irritability: they Initiate nerve inpulses in reponse to                                        Stimuli from outside or inside the body

                         -conductivity: ability To transmit a impulse.
