They connect to a cell body which is the control centre of the neuron and send out impulses which travel along the axon and terminates at the axon terminal.
myelin sheath
forms an insulating layer within the brain and spinal cord and forms around the axon.
This allows nerve impulses to transmit more rapidly along the axon
Sensory receptors
transmit nerve impulses to the spinal cord and brain.
convert information into neural impulses which are translated into sensations (heat, pain, visual input, sound input) once they reach the brain.
Some neurons are terminated at the spinal cord and not all information reaches the brain.
This allows reflex actions to occur quickly without the delay of impulses needing to reach the brain
Relay neurons are located
within the brain and spinal cord
Relay neurons allow...
motor neurons and sensory neurons to communicate bridging sensory input and motor reaction output; carrying messages from one part of the CNS to another.
Motor neurons are located in the
centralnervoussystem
Motor neurons
project their axons either directly or indirectly by forming synapses with muscles to control muscle contractions
release neurotransmitters when stimulated which bind to muscle receptors and trigger movements.
