Question

1.) An action potential carried in one nerve fiber fascicle cannot stimulate adjacent fascicles because of the

	perineurium.
	subarachnoid space
	epineurium.
	endoneurium.
	dura mater.

2.) Graded potentials are produced by voltage gated channels.

	True
	False

Answer 1

1.) An action potential carried in one nerve fiber fascicle cannot stimulate adjacent fascicles because of the

Answer: endoneurium.

it surrounds each myelinated axon in the Peripheral Nervous System.

fascicles is the name for a group of myelinated endoneurium enclosed axons surrounded by perineurium

2.) Graded potentials are produced by voltage gated channels.

Answer:True

Graded potentials are mainly produced by voltage gated channels.

Graded potentials are electrical signals in dendrites and cell body soma of a nerve cell.

Graded potentials are caused by opening and closing of many kinds of channels whereas ation potential are caused by the opening and closing of voltage gated-ion channels.
