Neural Activity 1

Types of cells

Glia

Radial glia

Guide axon growth over long distances

Oligodendycytes

Form myelin around cells in CNS

Schwann cells

Form myelin around cells in PNS

Microglia

Removes waste material from NS

Astrocytes

Regulates electrical activity of neurons

Interneurons

neuron confined within given structure

Motor neurons

Conducts impulses to muscles

Sensory neurons

Sensitive to stimulation

Anatomy of neurons

Efferent axon

Sends information away from structure

Afferent axon

Brings information into structure

Presynaptic Terminal

Point where axon releases chemicals

Nodes of Ranvier

Interruptions in myelin

Myelin Sheath

Insulating material around axon

Axon

Information sender

Soma

structure containing nucleus

Purkinje cells

Multipolar cells

Bipolar cells

Unipolar cells

Animal Cells

Mitochondria

Perform metabolic activities

Nucleus, ER & Ribosomes

Contains DNA & protein synthesis

Cell Membrane

Seperates inside of cell from outside environment
