Neurons Model

Axon;conducts nerve impulses away from the body cell body

Axon Hillock;Trigger zone where action potentials begin

Axon Terminals;Release neurotransmitters to communicate with other cells

Cell Body, Soma, perikaryon ;  Contains nucleus; integrates incoming signals

14

Dendrites; Receive signals from other neurons

Endoneurium;Connective tissue around each axon

11

Myelin Sheath;Insulates axon, increases speed of impulse conduction

line of site in 10

Nodes of Ranvier; Gaps in myelin; enable saltatory conduction

4

Neurofibrils; Cytoskeletal support inside neurons

7

Neurolemmocyt, Schwann cell; Myelinates PNS axons

10 (little things)

Nissl Bodies; Rough ER for protein synthesis

2

Nucleus of Neuron; Contains neuronal DNA

5 (end)

Synaptic End Bulbs, release neurotransmitters
