Nerve impulse transmission between cells of the CNS without any delay can be attributed to
A)the presence of a neuromuscular synapse between the cells.
B)communicating junctions that permit the passage of ions between the cells.
C)the activity of Schwann cells.
D)the number of neurons in the chain.
E)drinking an energy drink.

Question

Quizplus · Accepted Answer

Communicating junctions, also known as gap junctions, allow for the passage of ions between cells, creating a direct electrical connection between the cells. This allows for fast transmission of nerve impulses within the CNS without any delay. Neuromuscular synapses and Schwann cells are involved in the transmission of nerve impulses in the PNS, not the CNS. The number of neurons in the chain is not necessarily correlated with the speed of nerve impulse transmission. Drinking an energy drink may increase alertness and energy levels, but it does not directly affect nerve impulse transmission.
