Question

A chemical synapse ALWAYS includes ________.

1. Axon terminal
2. Presynaptic cell
3. Synaptic cleft
4. Post synaptic cleft
5. Dendrite

A. 1, 2, 3, 4, 5

B. 1, 2, 3, 4

C. 2, 3, 4

D. 2, 3, 4, 5

E. 1, 3, 4

Answer 1

A chemical synapse always includes an axon terminal, presynaptic cell, synaptic cleft, post synaptic cleft, and dendrite. Hence the correct answer is option D

Step-by-step explanation:

The correct answer is Option D: 2, 3, 4, 5. A chemical synapse always includes the following:

1. Axon terminal - which releases neurotransmitters
2. Presynaptic cell - the neuron sending the signal
3. Synaptic cleft - the narrow space between the presynaptic and postsynaptic membranes
4. Post synaptic cleft - the neuron receiving the signal
5. Dendrite - where the signal is transmitted to

These components are necessary for the transmission of signals between neurons in a chemical synapse.

Hence the correct answer is option D
