Neurons & Glial Cells
● Soma - life source of neuron
● Dendrites - pick up information/neurotransmitters
● Dendritic spines - more surface area to pick up information
● Axon hillock - interprets information
● Axon - information travels down axon
● Myelin sheath - layer of tissue that covers the axon; allows information to be processed
quicker
● Axon terminals/Terminal buttons - releases neurotransmitters to next neuron

● Neuron = brain cell
● Neuron Doctrine: the idea that the human brain is made up of individual neurons.
● 3 types of neurons:
1) Motor - motion and function
2) Sensory - senses (sight, hearing, taste, touch, smell)
3) Inter - allow communication between motor and sensory neurons
● Glial cells = support cells
➔ Microglia - clean up debris and dead neurons
➔ Astrocytes - repair neurons; also helps with blood-brain barrier
➔ Schwann - creates myelin sheath in the peripheral
➔ Oligodendroglia - creates myelin sheath in the central nervous system
