Section 1

(6 cards)

conduction velocity: 1 m/s diameter: 1 µm Function: - autonomic postganglionic fibers - protophatic sensation

Front

Give the conduction velocity, diameter and function of C (unmyelinated) nerve fibers:

Back

conduction velocity: 30-70 m/s diameter: 8 µm Function: - somatosensory fibers → epicritic sensation → proprioception - sensory fibers golgi tendon organ (1b)

Front

Give the conduction velocity, diameter and function of Aβ nerve fibers:

Back

conduction velocity: 15-30 m/s diameter: 5 µm Function: motor fibers of muscle spindle

Front

Give the conduction velocity, diameter and function of Aγ nerve fibers:

Back

conduction velocity: 3-15 m/s diameter: 3 µm Function: - autonomic preganglionic fibers

Front

Give the conduction velocity, diameter and function of B (thin myelin) nerve fibers:

Back

conduction velocity: 70-120 m/s diameter: 15 µm Function: - motor neurons (skeletal muscle) - sensory fibers of muscle spindle (1a)

Front

Give the conduction velocity, diameter and function of Aα nerve fibers:

Back

conduction velocity: 12-30 m/s diameter: 3 µm Function: - somato sensory fibers -> protopathic sensation

Front

Give the conduction velocity, diameter and function of Aδ nerve fibers:

Back
