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
Dendrite
Fibers that receive information from other neuron
Categorising neurons
Pyramidal cells
Chandellier cells
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
