The formation of mesodermal clusters that are arranged segmentally along the anterior posterior axis of an embryo.

A process in which force is generated within skeletal muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. In the skeletal muscle, the muscle contraction takes advantage of an ordered sarcomeric structure and in most cases it is under voluntary control.

The enlargement or overgrowth of all or part of the heart muscle due to an increase in size of cardiac muscle cells without cell division.

The process whose specific outcome is the progression of the adult heart over time, from its formation to the mature structure.

The physiological enlargement or overgrowth of all or part of the heart muscle due to an increase in size (not length) of individual cardiac muscle fibers, without cell division, as a result of a disturbance in organismal or cellular homeostasis.

The sliding of actin thin filaments and myosin thick filaments past each other in muscle contraction. This involves a process of interaction of myosin located on a thick filament with actin located on a thin filament. During this process ATP is split and forces are generated.

The aggregation, arrangement and bonding together of proteins to form the actin-based thin filaments of myofibrils in skeletal muscle.

The process resulting in the transition of the otic placode into the otic vesicle, a transient embryonic structure formed during development of the vertebrate inner ear.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a myofibril being extended beyond its slack length.

The series of events by which a muscle stretch stimulus is received by a cell and converted into a molecular signal.

The series of events by which a muscle stretch stimulus is received by a cell and converted into a molecular signal.

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.

The aggregation, arrangement and bonding together of a set of macromolecules to form a protein-containing complex.

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

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

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

A region of a sarcomere that appears as a light band on each side of the Z disc, comprising a region of the sarcomere where thin (actin) filaments are not overlapped by thick (myosin) filaments; contains actin, troponin, and tropomyosin; each sarcomere includes half of an I band at each end.
