Integreting sensery information and coordinating both concious and unconcious activity

The PNS is all the other nerves (not in the spinal chord and brain) over the body. Their goal is to get information from and to the brain through the spinal chord.

Carries sensory information to the CNS and motor information from the CNS

Sensory information is recieved at at the sensory receptor sights (skin, muscles, etc) snd carried along the sensory neural pathway

Involuntary control of organs and smooth muscle; unconcious response

Activates when a danger is present or we feel an extreme emotion

Calm or restores the body to its normal functioning after the Sym NS has been activated

A neuron is an individual cell that is specialised to receive, process and/or transmit information.Neurons comminicate with eachother through muscles and with glands. They are the building blocks of the brain and nervous system.

Neurons carry information called an action potental (or neural impulse) to the appropriate part of the nervous system or, they interprite a message and enable a response.

Neurons have specialised functions and bary in shape and size depending on where they are located and what is their specific function.

Insulates the axon, protects neuron and speeds up the transmission of AP

Contains chemicles called neurotransmitters - When AP reaches the axon terminals, they secrete the neurotransmittors which travel to the dendrites of another neuron
