Nondirected synapses

D) both A and B
E) both B and C

Question

Quizplus · Accepted Answer

Nondirected synapses involve the release of neurotransmitter molecules diffusely into the extracellular fluid, and they can be sometimes string-of-beads synapses. Therefore, option D (both A and B) is the correct answer. Option C is incorrect because gap junctions are involved in electrical synapses, not nondirected synapses. Option E is also incorrect as it combines unrelated types of synapses.
