The myofibril assembly process that results in the 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.

A cytoskeleton organization process that directly or indirectly links cytoskeletal filaments to the plasma membrane.

The attachment of a cell, either to another cell or to an underlying substrate such as the extracellular matrix, via cell adhesion molecules.

The attachment of a cell, either to another cell or to an underlying substrate such as the extracellular matrix, via cell adhesion molecules.

The directed movement of a border cell through the nurse cells to reach the oocyte. An example of this is found in Drosophila melanogaster.

The spreading of the amnioserosa from its compressed state to cover the whole of the dorsal surface. Initiating in the thorax and spreading posteriorly, it is accompanied by the transition from a parasegmental to segmental division of the embryo.

The coming together of the dorsal and ventral surfaces of the imaginal disc-derived wing during the conversion of a folded single layered wing disc to a flat bilayered wing.

The process whose specific outcome is the progression of the larval somatic muscle over time, from its formation to the mature structure.

The developmental process in which a skeletal muscle attaches to its target (such as bone or body wall).

The attachment of a cell, either to another cell or to an underlying substrate such as the extracellular matrix, via an integrin, a heterodimeric adhesion receptor formed by the non-covalent association of particular alpha and beta subunits.

Ensuring that tracheal tubes in an open tracheal system maintain their epithelial structure during the cell shape changes and movements that occur during the branching process.

Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.

The attachment of one cardiomyocyte to another cardiomyocyte via adhesion molecules.

The developmental sequence of events leading to the formation of adult skeletal muscle tissue. The main events are: the fusion of myoblasts to form myotubes that increase in size by further fusion to them of myoblasts, the formation of myofibrils within their cytoplasm and the establishment of functional neuromuscular junctions with motor neurons. At this stage they can be regarded as mature muscle fibers.

The process in which a relatively unspecialized cell acquires specialized features of a neural crest cell.

The process in which the anatomical structures of the viscerocranium are generated and organized during the embryonic phase. The viscerocranium is the part of the skull comprising the facial bones.

The process whose specific outcome is the progression of a cardiac muscle cell over time, from its formation to the mature state.

The process whose specific outcome is the progression of a cardiac muscle cell over time, from its formation to the mature state.

The closure of the temporary ventral gap in the optic cup that contributes to its shaping.

The aggregation, arrangement and bonding together of a set of components to form a junction between cells.

The attachment of a cell, either to another cell or to an underlying substrate such as the extracellular matrix, via cell adhesion molecules.

Formation of terminal branches in the open tracheal system. These are long cytoplasmic extensions that form fine tubules that transport oxygen directly to the tissues. An example of the process is found in Drosophila melanogaster.

Creation of the central hole of a tube in an open tracheal system through which gases flow.

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 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.

Small region on the surface of a cell that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments.

Small region on the surface of a cell that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments.

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.

A collagen-containing extracellular matrix consisting of a thin layer of dense material found in various animal tissues interposed between the cells and the adjacent connective tissue. It consists of the basal lamina plus an associated layer of reticulin fibers.

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

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

A cell-cell adherens junction that contains the transmembrane protein N-cadherin, which interacts with identical molecules from neighboring cells to form a tight mechanical intercellular link; forms a large portion of the intercalated disc, the structure at which myofibrils terminate in cardiomyocytes.

Small region on the surface of a cell that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments.

The part of the cytoskeleton (the internal framework of a cell) composed of actin and associated proteins. Includes actin cytoskeleton-associated complexes.

The portion of the plasma membrane at the lateral side of the cell. In epithelial cells, lateral plasma membranes are on the sides of cells which lie at the interface of adjacent cells.

Platelike region of a muscle sarcomere to which the plus ends of actin filaments are attached.

The junction between a nerve fiber of one neuron and another neuron, muscle fiber or glial cell. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane.
