Central nervous system (CNS)
comprises of spinal cord and the brain. It receives information from the senses and controls the body's responses.
1 of 18
Spinal cord
Bundle of nerve fibres enclosed within the spinal column and which connects nearly all parts of the body
2 of 18
Brain
responsible for coordinating sensation, intellectual and nervous activity.
3 of 18
Peripheral nervous system
Part if the nervous system outside the brain
4 of 18
Autonomic nervous system
governs the brain's involuntary activities and is self regulating. Split into the sympathetic branch- fight or flight and parasympathetic branch- rest and digest
5 of 18
Somatic nervous system
Part of the peripheral nervous system responsible for carrying sensory and motor information to and from the central nervous system
6 of 18
Neurotransmitter
chemical substances that play an important part in the workings of the nervous system by transmitting nerve impulses across a synapse.
7 of 18
Sensory neurons
carry impulses from sensory receptors to the spinal cord and the brain
8 of 18
Relay neurons
allow sensory and motor neurons to communicate with one another
9 of 18
Motor neurons
Form synapses with muscles and control their contractions
10 of 18
Synapse
Conjunction of the end axon of one neuron to the dendrite or cell body of another
11 of 18
Synaptic transmission
Process by which a nerve impulse passes across the synaptic cleft from one neuron to another

Endocrine glands
special group of cells within the endocrine system
13 of 18
