Everything we do is complex - we are constantly sending electrical messages to do things

Sensory neurons detect changes in external and internal environments

motor neurons cause the contraction of muscles and the activation of glands

interneurons communicate between nerves

The Cell Body is also known as the Soma

the Soma contains the nucleus

Membrane of the cell acts as a boundary between outside of cell and inside

the membrane is imbedded with protein. This cell protein is made of amino acids

Cytoplasm is a semiliquid within the cell. It contains the chromosomes

chromosomes are the gene recipe for individual proteins

Mitochondria extract energy from nutrients

Mitochondria is located inside the cytoplasm

Dendrites help neurons talk to each other

Neural messages are transmitted from neuron to neuron across the synapse

the synapse is also known as the Synaptic cell

Axon is a long tube that carries information from the soma to the terminal buttons

microtubules track and transport proteins

myelin sheath is made of a fatty substance

\

Glial means glue

Glial cells supply nutrients and chemicals needed for neural communication

Astrocytes or Star cells provide the nutrients and substances. They also regulate chemical composition of extracellular fluid. They ensure good communication between neurons and clear out dead neurons.

phagocytosis - clearing up dead neurons

Oligodendrocytes support axons and produce the myelin sheath

microglia are the small cells that are involved with phagocytosis and protect the brain from invading microorganisms
