What are the 12 Cranial Nerves
(On old Olympus’ towering top a Fin and German viewed some hops)
(Some say marry money but my brother says big brains matter most)
- Olfactory - S
- Optic - S
- Oculomotor - M
- Trochlear - M
- Trigeminal - B
- Abducens - M
- Facial - B
- Acoustic - S
- Glossopharyngeal - B
- Vagus - B

- Hypoglossal - M
Define Axon
Fibers that take impulses away from the cell body
Define Dendrite
Fiber branches that receive impulses from other parts of the nervous system and bring them to the cell body
Define Synapse
Gap between neurons that transmits impulses
Gray Matter contains what type of fibers?
Unmyelinated
White Matter contains what type of fibers?
Myelinated
Describe Efferent Impulses
Impulses moving from the spinal cord to the body part.
Motor Neurons

What are the 3 Stages of Motor Planning? Define each.
- Cognitive Phase: Everything is new and you are learning how to do everything from the beginning.
- Associated Phase: Learning to put all of the pieces together. Starting to refine the skill to make it better.
- Autonomous Phase: Becoming the best you can be at a certain skill. Have to keep practicing in order to maintain the skill level. This is done repetitively.
What are the 4 Phases of Developmental Strategies to Improve Motor Control?
- Improve Mobility: assume posture, but do NOT maintain it. (AAROM, repeated contractions with stretch, hold-relax techniques)
- Improve Stability: ability to remain in posture before moving to next posture. (placing and holding, alternating isometrics, rhythmic stabilization)
- Improve Controlled Mobility: ability to move with in posture but NOT develop a skill. (weight shifting, PNF patterns) ex: lunges or jumping jacks
- Improve Skill: making progress moving in different directions from one point to another. (resisted progression, coordinated exercises) ex: lunge walking
What spinal nerve goes below the head
11 - Spinal Accessory Nerve
Define Hypotonia
A decrease in muscle tone
Define Ataxia
A loss of power of muscle coordination
ex. CP child
Define Dysdiadochokinesia
Impaired ability to perform rapid alternating movements
Define Rebound Phenomenon
The loss of the check reflex which functions to HALT a forceful active movement
Define Dysmetria
A disturbance in the ability to judge the distance or range of a movement. Pt will go past or not be able to directly reach an item.
