Any process that modulates the frequency, rate or extent of ovulation, the release of a mature ovum/oocyte from an ovary.

Cell motility due to the motion of one or more eukaryotic cilia. A eukaryotic cilium is a specialized organelle that consists of a filiform extrusion of the cell surface. Each cilium is bounded by an extrusion of the cytoplasmic (plasma) membrane, and contains a regular longitudinal array of microtubules, anchored basally in a centriole.

OBSOLETE. Cell motility due to the motion of one or more flagella.

Any process that decreases the rate or extent of the process whose specific outcome is the progression of an oocyte over time, from initial commitment of the cell to its specific fate, to the fully functional differentiated cell.

Any process that increases the rate, frequency or extent of myofibril assembly by organization of muscle actomyosin into sarcomeres. The sarcomere is the repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs.

An endosome present in the presynapse that fuses with endocytic vesicles arising in the presynaptic endocytic zone. This organelle is believed to be involved in regeneration of synaptic vesicles.

A specialized region below the presynaptic membrane, characterized by electron-dense material, a specialized cytoskeletal matrix and accumulated (associated) synaptic vesicles.

A recycling endosome that is organized around the microtubule organizing center, close to the nucleus. This is the main recycling endosome of most cells. It receives input from the Golgi as well as recycled molecules from early endosomes.

A specialized region of the plasma membrane and underlying cytoplasm which surround the the active zone, into which synaptic vesicle membranes are recycled following exocytosis. It is especially enriched in endocytic proteins following intense activity.

The cytoplasmic component of the presynaptic endocytic zone.

The region of the presynaptic membrane that is part of the presynaptic endocytic zone - where synaptic vesicles are endocytosed and recycled following release.

A recycling endosome of the postsynapse. In postsynaptic terminals with dendritic spines, it is typically located at the base of a dendritic spine. It is involved in recycling of neurotransmitter receptors to the postsynaptic membrane. In some cases at least, this recycling is activated by postsynaptic signalling and so can play a role in long term potentiation.

An endosomal compartment that is part of the post-synapse. Only early and recycling endosomes are typically present in the postsynapse.

The process in which a folic acid, or one of its derivatives (dihydrofolate, tetrahydrofolate, methylene-tetrahydrofolate or methyl-tetrahydrofolate) is transported across a membrane.

A process that modulates synaptic plasticity such that synapses are changed resulting in the decrease in the rate, or frequency of synaptic transmission at the synapse.

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.

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

Differentiated cytoplasm associated with a pole of an oocyte, egg or early embryo that will be inherited by the cells that will give rise to the germ line.
