| Name the subdivisions of the peripheral nervous system | voluntary and autonomac |
| List the structures of the CNS | Brain and Spinal cord |
| List the parts of the neuron and their functions | dendrites- recpetor cell body- organelles/ neurotransmitter axon- sackules are here |
| Whats the functions of sensory neurons? | recieve stimulus from periphery and carry to CNS |
| What is the function of motor neurons? | carry from CNS to periphery |
| What is the function of interneurons? | central, association, internunical.- makes up brain and spinal cord |
| What is the function of an Axon? | sends stimulus |
| What is the function of a Dendrite? | recieve stimulus |
| What is the function of a Cell body? | organelles- neurotransmitter forms here |
| Define synapse | Chemical communication between axon of one and dendrite on another |
| Define synaptic gap | synaptic cleft- space between axon and dendrite |
| Define Reflex/ reflex arc | No brain envolvement |
| What is a neurotransmitter? | A chemical |
| Where is the neurotransmitter stored? | Sacule |
| What is a neurotransmitter that is often seen in the periphery? | acetycholine |
| Define myelin | a white sheath that covers neurons- white matter- schwan cells form it |
| What is in the subarachnoid space? | blood vessels |
| List parts of the brain stem | medulla, pons and midbrain |
| Define afferent | carry toward |
| define efferent | carry from |
| What is the dorsal root ganglion? | group of cell bodies of the sensory neuron |
| What structures form the gray H shaped area of the spinal cord? | dorsal and ventral horn. Axon of sensory- interneurons |
| Name of concentration of cell bodies of sensory neurons | dorsal root ganglion |
| What is a plexus? | Large nerve from when small nerves branch off of |
| What plexus is commonly used for administering anesthesia? | Lumbo sacral |
