N +SN cant remember

• How does a sensory neuron function?

  It carries impulses from sensory receptors to the CNS, converting sensory information to neural impulses.
• What is the role of a relay neuron?

  It connects sensory and motor neurons and allows them to communicate with each other, found in the CNS.
• What are neurotransmitters?

  They are chemical messengers that transmit signals across the synaptic gap to receptor sites on the postsynaptic cell.
• What is the function of a motor neuron?

  It carries nerve impulses to muscles or effectors, triggering a response eg.muscle contraction.
• somatic nervous system consists of sensory and motor neuron
• the somatic nervous system enables reflex actions
• a neuron enables communication with the nervous system
• dendrites carry functional information towards the cell body
• cell body contains genetic material
• at the axon terminal synaptic connections are made with other cells, axon terminals contain neurotransmitters which are released to communicate with other neurons or directly to organs,and in turn to influence a function.
• Motor neuron - carries impulses from cns to muscles or effectors to bring about a response eg. Muscle contraction
