Neurons - nerve cells that conduct electrical impulses and relay information
Parts of a neuron - The dendrites, cell body, and axon
T/F: Neurons undergo mitosis. - False
How long can neurons survive? - A person's entire lifetime
T/F: Neurons that die due to brain damage can be replaced. - False
How long can neurons survive without oxygen? - 3-5 minutes
Where are all nerve cell products synthesized? - The neuron cell body
The neuron cell body consists of: - a large nucleus with surrounding cytoplasm containing 
the normal organelles
Which direction is information is received and sent from within a neuron? - The same 
direction
Dendrites - numerous short extensions that emanate from the cell body
The nervous system - receives information, processes information, and sends out signals to 
the muscles and glands to elicit an appropriate response
What is nervous tissue responsible for and how does it do it? - Communication between the 
cells of the body by forming a system of electrical impulses
What are the two main divisions of the human nervous system? - The Central Nervous 
System (CNS) and Peripheral Nervous System (PNS)
The central nervous system includes: - the brain and spinal cord
nuclei - Collections of cell bodies inside the central nervous system
Tracts - the collection of nerve axons in the central nervous system
The peripheral nervous system includes: - cranial nerves and spinal nerves: all nerves not in 
the brain or spinal cord
brainstem regions - the midbrain, pons, and medulla
Cranial nerves project from the ___. - brainstem
Spinal nerves project from ___. - either side of the spinal cord
What do cranial nerves generally innervate? - the face, head, and neck
What do spinal nerves innervate? - trunk and limbs
ganglia - Collections of cell bodies inside the peripheral nervous system
nerves - hundreds of thousands of axons wrapped together in a connective tissue
