PNS
PNS
Motor function
alpha = lower motor neuron, skeletal muscle endplate
-
-
-
Small Receptor Field
Merkel - pressure, slow adapting
Meissner - touch, movement rapid adapting
Large Receptor Field
Ruffini - pressure, rapid adapting
Pacinian - vibration, slow adapting
Sensory Functions
-
Abeta = meissner corpuscles, merkel endings, pacinian corpuscles/Type II
Agamma = sharp pain cold, touch
C = slow pain, itch, some touch
-
-
-
Neurapraxia - reversible nerve impairment, parasthesia, Saturday night palsy
-
Recall the classification schema of axons and recall the motor and sensory functions subserved by each category.

Recall the cutaneous receptors including the size of their receptive fields (as covered), their function(s), and their adaptation.
Small Receptor Field
Merkel - pressure, slow adapting
Meissner - touch, movement rapid adapting
Large Receptor Field
Ruffini - pressure, rapid adapting
Pacinian - vibration, slow adapting
Recall the sensory structures which give rise to the position and movement senses and contrast them; basic facts about their structure, adaptation, and sensory modality. (Muscle spindles, golgi tendon organs)

-
Define neuropathy (mono-, multiplex, and poly-), radiculopathy, neurapraxia, paresthesia; recall their generic presentation.
