B: Contains the nucles, concerned with metabolism and function of the cell
C: -Cell body located in CNS -axons run from CNS to skeletal muscles directly no ganglia involved
D: Brain and spinal cord
2. Regeneration of an axon depends on..
A: Inherited neuro-degenerative disorder (fatty substances accumalate in the nerve cells)
B: 1.Location of injury,2.Type of injury 3.Inflammatory response 4.Process of scarring 5.Cell body staying
C: Comes into the ganglia
D: Nicotonic-on post ganglionic cell body Muscuranic-on effector organ (just PNS)
3. Junctions
A: Space between the nerve fiber cells and the effector cells
B: Nicotonic-on post ganglionic cell body Muscuranic-on effector organ (just PNS)
C: Conducts nerve impulses away from the cell body
D: Comes into the ganglia
4. All preganglionic neurons release??
A: Acetylecholine
B: -Cell body located in CNS -axons run from CNS to skeletal muscles directly no ganglia involved
C: Disrupted dignals to muscles
D: Produce growth factor
5. Peripheral nerves are comprised of
A: Afferent (goes up) Efferent nerves (goes down)- Somatic NS (voluntary Autonomic (Involuntary)
B: stimulate the adrenal gland-releases 80% Epi and 20% nor epi
C: Gaps formed between the myelin sheath-
D: Epinephrine and norepinephrine
6. SNS preganglionic cells bodys found in
A: COMT-Catecholamethyltransferase-breaks norepi &epi MAO-MOnoamineOxidase-breaks down dopamine
