NERVOUS SYSTEM
Types of Neurons
1. DENDRITE...
a slender, branched projection of a neuron, which conducts the electrical stimulation received from other cells to and from the cell body, or soma, of the neuron from which it projects.
2. CELL BODY (SOMA)...
the bulbous end of a neuron, containing the nucleus and is where most protein synthesis occurs.
3. NUCLEUS...
controls chemical reactions within the cytoplasm and stores information needed for cellular division.
4. AXON...
a long slender projection of a neuron which conducts electrical impulses away from the neuron's cell body.
5. MYELIN SHEATH...
an electrically insulating phospholipid layer that surrounds the axons of many neurons, composed of about 80% lipid fat and about 20% protein. It helps prevent the electrical current from leaving the axon and causing a short circuit in the brain.
6. AXON TERMINAL...
a specialized structure at the end of the axon that is used to release neurotransmitter and communicate with target neurons.
