explain the three different types of neurons
Relay- connect other neurons. Motor- transmits messages from the CNS to the muscles and organs. Sensory-transmits messages towards the CNS from the muscles and organs
1 of 12
explain the two main divisions of the nervous system
central nervous system- this includes the brain and spinal cord. Peripheral nervous system- this is all the nerves that connect the brain and spinal cords to the rest of the body
2 of 12
explain the two main divisions of the peripheral nervous system
autonomic nervous system- this deals with the involuntary body functions. Somatic nervous system deals with voluntary body movements
3 of 12
explain the two main divisions of the autonomic nervous system
sympathetic nervous system- this is the system that triggers the flight or fight response. Parasympathetic nervous system- this is the system that returns the body to a relaxed state after a stressor

outline 2 hormones and their functions in the body or effect on behaviour
Testosterone- too much of this can lead to risk taking or aggression. Adrenaline- this hormone prepares our body for stress by triggering the fight or flight response
5 of 12
explain what is meant by the flight or fight response
the fight or flight response is an innate tendency for the body to prepare itself to runaway (flight) or fight against something that is causing them stress. it is triggered by the sympathetic nervous system.

explain the structure of a neuron
a neuron has dendrites which receive a signal at one end. a cell body containing a nucleus. an axon which is covered in myelin sheath ( to spread the signal) and then axon terminals at the end to the signal on.

explain the difference between inhibitory and excitatory neurons
the excitatory neurotransmitter is one that increase the positive charge of the neuron increasing the chance it will fire (dopamine). Whereas an inhibitory neurotransmitter is one that increases negative charge and therefore lower the change it fire

what are neurotransmitter and give examples
these are chemicals which carry a signal from one neuron to another. they are released at a synapse.Serotonin-low levels have been linked with depression and OCD. Dopamine- high levels link to schizophrenia
9 of 12
outline the endocrine system
is a system of glands which produce hormones. hormones are chemical messengers that travel in the bloodstream to specific organs of the body and cal also affect our behaviour
10 of 12
explain the process of synaptic transmission
one neuron communicates with another. information passed down the axon as an electrical impulse when that impulse reaches the synaptic vesicles they release their contents of neurotransmitters
11 of 12
what is the purpose myelin sheath
allows electrical impulses to transmit quickly and efficiently along the nerve cells.protecting the neurons
