CH 2: FUNCTIONAL NEUROANATOMY-THE NERVOUS SYSTEM AND BEHAVIOR
n Neurons - Highly organized cells that are specialized to communicate information.
Cell Body (Soma) - *Parts of Neurons*: Variable in shape and size, contains nucleus.
Function: synthesis, metabolism, energy
Dendrites - *Parts of Neurons*: Thin branching fibers, spiny or aspiny, decreasing diameter.
Function: Input
Axon - *Parts of Neurons*: Single thin extension, usually collateralized (branch), constant diameter.
Function: Transmission
Axon Hillock - *Parts of Neurons*: Site where axon exits soma.
Function: Establishing the axon potential
Myelin - *Parts of Neurons*: Fatting coating around axon.
Function: Insulation and conduction of action potential (AP)
Nodes of Ranvier - *Parts of Neurons*: Gaps in myelin.
Function: Facilitate conduction of action potential (AP)
Axon Terminals - *Parts of Neurons*: Swelling at tip of axon branch.
Function: Release neurotransmitters into synapse
Synapse - *Parts of Neurons*: Structure consisting of presynaptic membrane, cleft, and postsynaptic
membrane.
Function: Transmission of information
Cytoplasm - *Organelles related to neurons*: Fluid compartment of cell.
Function: Medium for chemical reactions
Nucleus - *Organelles related to neurons*: Contains genetic material.
Function: Encoding and transcribing mRNA
Ribosomes - *Organelles related to neurons*: Ribonucleoprotein molecule
Function: Translation of mRNA to protein
Endoplasmic Reticulum - *Organelles related to neurons*: Smooth or rough membranes.
