Asynapticcleft, or synaptic gap, can be found between a neuron and a. a gland. b. a musclecell. c. another neuron. d. all of these.

d. All of these

Explanation:

A synaptic cleft or synaptic gap is formed during synapsis. It is a gap between membrane of a axon end bulb and a membrane of a target cell. The target cell can be a muscle cell, a neuron, a gland. The membrane of a axon is called pre-synaptic membrane and membrane of a target cell is called post-synaptic membrane and the space between two membranes is called synaptic cleft. Through the synaptic cleft  impulse is transmitted with the help of neurotransmitters such as acetylcholine.
