Nerves - Coggle Diagram
Nerves
dendrites
receives nerve impulse from adjacent neuron's
end of branches of dendrons are called dendrites
covered with synapses
nerve fibres that transmit nerve impulses towards the cell body
schwanns cell
helps maintain physical integrity
receptors for neurotransmitters that respond to neurotransmission
release neuroactive substances that regulate strength of synaptic nerve
neuron
3 types: sensory, relay, motor
nucleus, dendrites, cell body, axon, myelin sheath, schwanns cell, node of ranvier, axon terminals
axon
electrical signals pass along
make contact with other cells
myelin sheath
insulates/protects axon from external influences
soma: cell body of nerve cell
myelin sheath provides an insulating layer
axon carries signals from soma to target
dendrites carry signal to soma
