Descriptions

The plasmid membrane Ca2+ pump (PMCA) extrudes Ca2+ from the cytosol to the extracellular space playing an important role in the maintenance of the resting level of intracellular Ca2+ and in the control of the Ca2+ transients. The PMCAs are of major physiological importance, with different isoforms being essential for presynaptic and postsynaptic Ca2+ regulation in neurons and for feedback signaling in the heart and sperm motility. The PMCAs belong to the subtype 2B of P-type ATPases. The C-terminal segment of the PMCA functions as an autoinhibitory domain by interacting with the catalytic core. Ca2+-calmodulin binds to the C-terminal segment and stops inhibition by switching the PMCA to an activated state of higher maximum activity and affinity for Ca2+. In the PMCA3, the G1107D replacement impairs the autoinhibition mechanism by introducing a negative charge perturbing the contacts between the calmodulin binding domain and the pump core.

Name Definition
apical plasma membrane The region of the plasma membrane located at the apical end of the cell.
basolateral plasma membrane The region of the plasma membrane that includes the basal end and sides of the cell. Often used in reference to animal polarized epithelial membranes, where the basal membrane is the part attached to the extracellular matrix, or in plant cells, where the basal membrane is defined with respect to the zygotic axis.
cilium A specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface and of some cytoplasmic parts. Each cilium is largely bounded by an extrusion of the cytoplasmic (plasma) membrane, and contains a regular longitudinal array of microtubules, anchored to a basal body.
cytoplasm The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
dendrite A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses 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.
dendritic spine membrane The portion of the plasma membrane surrounding a dendritic spine.
endoplasmic reticulum The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).
GABA-ergic synapse A synapse that uses GABA as a neurotransmitter. These synapses are typically inhibitory.
glutamatergic synapse A synapse that uses glutamate as a neurotransmitter.
intracellular membrane-bounded organelle Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane.
neuron projection A prolongation or process extending from a nerve cell, e.g. an axon or dendrite.
neuronal cell body The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites.

photoreceptor ribbon synapse A ribbon synapse between a retinal photoreceptor cell (rod or cone) and a retinal bipolar cell. These contain a plate-like synaptic ribbon.
plasma membrane The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
postsynaptic density membrane 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.
postsynaptic membrane 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.
presynaptic active zone membrane The membrane portion of the presynaptic active zone; it is the site where docking and fusion of synaptic vesicles occurs for the release of neurotransmitters.
presynaptic membrane A specialized area of membrane of the axon terminal that faces the plasma membrane of the neuron or muscle fiber with which the axon terminal establishes a synaptic junction; many synaptic junctions exhibit structural presynaptic characteristics, such as conical, electron-dense internal protrusions, that distinguish it from the remainder of the axon plasma membrane.

The Purkinje cell layer lies just underneath the molecular layer of the cerebellar cortex. It contains the neuronal cell bodies of the Purkinje cells that are arranged side by side in a single layer. Candelabrum interneurons are vertically oriented between the Purkinje cells.
