ANS 10/2

1. How many nerve systems involve ganglia?

• 4

• 3

• 5

• 6

1. Which is a common type of proprioceptor? 

• Baroreceptor

• Golgi tendon organ

• Muscle spindle

• Photoreceptor

What is the primary difference between myelinated and unmyelinated nerve fibers?

• 1. Myelinated fibers transmit signals more slowly than unmyelinated fibers.

• 1. Myelinated fibers have a faster transmission speed due to the insulation provided by the myelin sheath.

• 1. Unmyelinated fibers are only found in the central nervous system, while myelinated fibers are found in the peripheral nervous system.

• 1. Unmyelinated fibers have no ability to regenerate, while myelinated fibers can regenerate after injury.

1. Select the correct nerve fiber with its function

• Alpha - touch, pressure

• Beta - proprioception

• Gamma - muscle spindle

• Delta - somatomotor

Select the correct structures labeled “A” and “B” in the correct order.

• Schwann cell; fascicle

• Schwann cell; connective tissue

• Fascicle; vein

• Fascicle; Schwann cell

Remak Schwann cells or bundles are:

• Myelinated

• Non-myelinated

1. When is the golgi tendon organ activated?

• High tension in the muscle

• Muscle is stretched

• Muscle is fatigued

• None of the above
