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.

A heterotrimeric protein complex formed by the association of MMP7, DLG1 and either LIN7A or LIN7C; regulates the stability and localization of DLG1 to cell junctions.

The component of the postsynaptic density membrane consisting of the gene products that are tethered to the membrane only by a covalently attached anchor, such as a lipid group that is embedded in the membrane. Gene products with peptide sequences that are embedded in the membrane are excluded from this grouping.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

A cell junction that forms a connection between two or more cells in a multicellular organism; excludes direct cytoplasmic junctions such as ring canals.

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.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

The migrating motile tip of a growing neuron projection, where actin accumulates, and the actin cytoskeleton is the most dynamic.

The portion of the cytoskeleton that lies just beneath the plasma membrane.

The component of a plasma membrane consisting of gene products and protein complexes that are loosely bound to its cytoplasmic surface, but not integrated into the hydrophobic region.

All of the contents of a dendrite, excluding the surrounding plasma membrane.

All of the contents of a dendrite, excluding the surrounding plasma membrane.

A small, membranous protrusion from a dendrite that forms a postsynaptic compartment - typically receiving input from a single presynapse. They function as partially isolated biochemical and an electrical compartments. Spine morphology is variable including \thin\, \stubby\, \mushroom\, and \branched\, with a continuum of intermediate morphologies. They typically terminate in a bulb shape, linked to the dendritic shaft by a restriction. Spine remodeling is though to be involved in synaptic plasticity.

Cylindric portion of the dendrite, directly stemming from the perikaryon, and carrying the dendritic spines.

An axon arising from cerebellar projecting cells in the cochlea, vestibular nuclei, spinal cord, reticular formation, cerebellar nuclei and basilar pontine nuclei. Mossy fibers enter through all three cerebellar peduncles and send collaterals to the deep cerebellar nuclei, then branch in the white matter and terminate in the granule cell layer. Through this branching, a given mossy fiber can innervate several folia. Mossy fibers synapse on granule cells. The synaptic contacts are made at enlargements along the length of the mossy fiber called mossy fiber rosettes. The enlargements of the rosettes give the axons as \mossy\ appearance in Golgi stained preparations.

The specialized, terminal region of a neuron projection such as an axon or a dendrite.

A small membranous protrusion, often ending in a bulbous head and attached to the neuron by a narrow stalk or neck.

A specialized area of membrane facing the presynaptic membrane on the tip of the nerve ending and separated from it by a minute cleft (the synaptic cleft). Neurotransmitters cross the synaptic cleft and transmit the signal to the postsynaptic membrane.

A synapse in which an action potential in the presynaptic cell increases the probability of an action potential occurring in the postsynaptic cell.

The part of a cell encompassing the cell cortex, the plasma membrane, and any external encapsulating structures.

The part of a synapse that is part of the post-synaptic cell.

The membrane component of the postsynaptic density. This is the region of the postsynaptic membrane in which the population of neurotransmitter receptors involved in synaptic transmission are concentrated.

A network of proteins adjacent to the postsynaptic membrane forming an electron dense disc. Its major components include neurotransmitter receptors and the proteins that spatially and functionally organize neurotransmitter receptors in the adjacent membrane, such as anchoring and scaffolding molecules, signaling enzymes and cytoskeletal components.
