A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a mitochondrion; includes mitochondrial morphogenesis and distribution, and replication of the mitochondrial genome as well as synthesis of new mitochondrial components.

Any process that activates or increases the frequency, rate or extent of locomotion of a cell or organism.

Any process that modulates the frequency, rate or extent of development of the vulva. Vulval development is the process whose specific outcome is the progression of the egg-laying organ of female and hermaphrodite nematodes over time, from its formation to the mature structure. In nematodes, the vulva is formed from ventral epidermal cells during larval stages to give rise to a fully formed vulva in the adult.

Any process that stops, prevents, or reduces the frequency, rate or extent of epidermal growth factor receptor signaling pathway activity.

The cellular homeostatic process that preserves a muscle cell in a stable functional or structural state.

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.

The process in which a cell becomes capable of differentiating autonomously into a nematode vulval cell in an environment that is neutral with respect to the developmental pathway; upon specification, the cell fate can be reversed. In nematodes, the vulva is formed from ventral epidermal cells during larval stages to give rise to a fully formed adult vulva, which is the egg-laying organ of female and hermaphrodite nematodes.

Any process that activates or increases the frequency, rate or extent of engulfment of apoptotic cell.

A protein complex that is composed of one alpha subunit and one beta subunit, both of which are members of the integrin superfamily of cell adhesion receptors; the complex spans the plasma membrane and binds to extracellular matrix ligands, cell-surface ligands, and soluble ligands.

The external part of the cell wall and/or plasma membrane.

The midline of aligned thick filaments in a sarcomere; location of specific proteins that link thick filaments. Depending on muscle type the M band consists of different numbers of M lines.

A vinculin-containing myofibril attachment structure of striated muscle that connects sarcomeres to the extracellular matrix. In nematode body wall muscle, the dense body performs the dual role of Z-disk and costamere.
