Nervous System Pt. 1

Support, insulate, and protect

• Neurons

• Neuroglia

Demonstrate irritability and conductivity, and thus transmit electrical messages from one area of the body to another area

• Neurons

• Neuroglia

Release neurotransmitters

• Neurons

• Neuroglia

Are amitotic

• Neurons

• Neuroglia

Able to divide; therefore are responsible for most brain neoplasms

• Neurons

• Neuroglia

Releases neurotransmitters

• axon

• axon terminal

• dendrite

• myelin sheath

• neuron cell body

Conducts local electrical currents toward the cell body

• axon

• axon terminal

• dendrite

• neuron cell body

• Nissl bodies

Increases the speed of impulse transmission

• axon terminal

• dendrite

• myelin sheath

• neuron cell body

• Nissl bodies

Location of the nucleus

• axon

• dendrite

• myelin sheath

• neuron cell body

• Nissl bodies

Generally conducts impulses away from the cell body

• axon

• axon terminal

• dendrite

• myelin sheath

• Nissl bodies
