What do we call information collected by nervous tissue from the environment?
Stimuli
Stimuli is transformed by nervous tissue into…
Nerve impulses
Nerve impulses are passed to the…
spinal cord and brain
What do the spinal cord and brain do with nerve impulses?
Receive, interpret and initiate a response to effector organs
What perform the functions in nervous tissues?
neurons
What are supporting nervous tissue cells called?
Neuroglia
What is this part of the neuron called?
Soma or Cell body

What create myelin sheaths in the peripheral nervous system?
Schwann cells
What is this part of the neuron called?
Axon terminal or synaptic terminal
What is this part of the neuron called?
Axon terminal or synaptic terminal
What are notable parts of the soma?
nucleus, mitochondria and Nissl bodies
Where do dendrites conduct their nerve impulses towards?
Soma
Why are multipolar neurons considered highly branched?
Have 2 or more dendrites extending from the soma
What is the long cytoplasmic process extending from a soma (ONLY 1 PER NEURON)
Axon
What extends from the axon?
Synaptic terminals
What do synaptic terminals do?
Site for contact between neurons, transfer of neurochemical signals
Most axons are enveloped by single or multiple folds of neuroglia sheath cells called…
Nerve fibres
