End of peripheral neurons monitor conditions ( light, sound, temperature).

• Sensory Reception

• Integrative Functions

Sensory messages that get sent repeatedly get remembered "motor functions" (subconscious actions).

• Integrative Functions

• Axon

The long threadlike part of a nerve cell that carry the nerve impulse.

• Axon

• Myelin Sheath

Branch like extensions on a neuron that GET signals and connect to the synapse.

• Dendrites

• Neurotransmitters

Chemicals that transmit signals across a synapse from one neuron to another 'target' neuron.
