A secretory organelle, typically 50 nm in diameter, of presynaptic nerve terminals; accumulates in high concentrations of neurotransmitters and secretes these into the synaptic cleft by fusion with the 'active zone' of the presynaptic plasma membrane.

The leaflet the plasma membrane that faces the cytoplasm and any proteins embedded or anchored in it or attached to its surface.

A neuron projection that has a short, tapering, often branched, morphology, receives and integrates signals from other neurons or from sensory stimuli, and conducts a nerve impulse towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.

The lipid bilayer surrounding a cytoplasmic vesicle.

A vesicle found in the cytoplasm of a cell.

A vesicle found in the cytoplasm of a cell.

The lipid bilayer surrounding a melanosome.

The lipid bilayer surrounding a melanosome.

A prolongation or process extending from a nerve cell, e.g. an axon or dendrite.

The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites.

Terminal inflated portion of the axon, containing the specialized apparatus necessary to release neurotransmitters. The axon terminus is considered to be the whole region of thickening and the terminal bouton is a specialized region of it.

The portion of the cell soma (neuronal cell body) that excludes the nucleus.

A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
