Nervous Sys- Anatomy

What are the branched nerve fibers that receive impluses toward the cell body of a neuron?

• Dendrites
• Axon
• Terminal
• Neuron

 What conducts electrical impulses away from the neuron's cell body?

• Axon
• Dendrite
• Terminal
• Perkinje Fibers

branch of the nervous system that consists of the brain and spinal cord

• Central Nervous System
• Peripheral Nervous System
• Brain Stem
• Limbic System

Branch of the nervous system that is outside the central nervous system:
Cranial Nerves
Spinal Nerves 
Autonomic Nervous System

• Cranial Nerves
• Limbic System
• Central Nervous System
• Peripheral Nervous System

3 membranes that over the brain and spinal cord: dura mater, arachnoid mater and pia mater

• Meninges
• Gray Matter
• Cerebrum
• Mucosa

neuroglial wrapping around an axon, insulates electricity inside the axon increasing the speed of the impulse

• Coating
• Mucous
• Myelin Sheath
• Dendrite

largest portion of the brain; 4 lobes: frontal, parietal, temporal and occipital
Responsible for conscious thought and reasoning

• Medulla
• Cerebrum
• Pons
• Amygdala

Fluid produced in the brain ventricles, provides nutrients, hormone, waste products, gases etc.

• Cerebral Spinal Fluid
• Water
• Mucosa
• Plasma
