14) Schwann cells are associated with myelin sheath.Myelin sheath membrane originate from and are a part of the Schwann cells.
Nodes of ranvier- are the gaps between the myelin insulation of Schwann cells which insulate the axon of neurons.
Unmyelinated axons- they have no association and function related to Schwann cells
Synaptic cleft-It is the gap between presynaptic and post synaptic cells
