Which of the following is not a true statement regarding Schwann cells?
|
|
Schwann cells speed up the nerve impulse
|
|
|
Action potentials only occur along the nodes of Ranvier
|
|
|
Schwann cells protect surrounding tissue
|
|
|
Action potentials occur beneath the Schwann cells
|
Explanation:
Detailed explanation-1: -Schwann cells are associated with “Axon".
Detailed explanation-2: -The Schwann cells arrange a regeneration pathway along a tube of the basal lamina for the stump of the axon. The sprout of the damaged axon can then grow through this tube which helps to stimulate and guide its regeneration.
Detailed explanation-3: -In the peripheral nervous system glial functions are exerted by Schwann cells (SCs). SCs sense synaptic and extrasynaptic manifestations of action potential propagation and adapt their physiology to support neuronal activity.
