In what locations within a neuron are you most likely to find the following components at high concentrations? (You do not have to use every location and you can use a location more than once.)

Neurotransmitter vesicles

Voltage gated Na channels

Voltage gated Ca channels

Ligand gated ion channels

Solution

Answer:

Neurotransmitter vescicles are synaptic vesicles which stores various neurotransmitter for releasing in the synapse. The location of the axon that harbors these vesicles is the axon terminal (bouton).

Voltage gated Na channels consists of passive channels and chemically gated channels. Passive channels are located on dendrites, axons and the cell body. Chemically gated channels are located on dendrites and cell body of the axon.

Voltage gated Ca channels are the mediators of depolarization-induced calcium entry into neurons. The are primarily located on the cell body and dendrites of neurons.

Ligand gated ion channels are located on the post synaptic side or the receiving side of the neuron.
