Membrane-bound structure found within muscle cells that is similar to the smooth endoplasmic reticulum in other cells.
Cardiac and skeletal muscle cells contain structures called transverse tubules (T-tubules), which are extensions of the cell membrane that travel into the centre of the cell.
Cell membrane of a muscle cell.
A special feature of the sarcolemma is that it invaginates into the sarcoplasm of the muscle cell, forming membranous tubules radially and longitudinally within the fiber called T-tubules or transverse tubules.
One of three types of vertebrate muscle tissue, with the other two being skeletal muscle and smooth muscle.
Cardiomyocytes contain T-tubules, pouches of cell membrane that run from the cell surface to the cell's interior which help to improve the efficiency of contraction.
Part of the high-voltage activated family of voltage-dependent calcium channel.
In skeletal muscle, there is a very high concentration of L-type calcium channels, situated in the T-tubules.
Smallest functional unit of striated muscle tissue.
The action potential then travels along T-tubules (transverse tubules) until it reaches the sarcoplasmic reticulum.
Activation of tension-generating sites within muscle cells.
DHPRs are located on the sarcolemma (which includes the surface sarcolemma and the transverse tubules), while the RyRs reside across the SR membrane.
Skeletal muscles (commonly referred to as muscles) are organs of the vertebrate muscular system that are mostly attached by tendons to bones of the skeleton.
T tubules are the pathways for action potentials to signal the sarcoplasmic reticulum to release calcium, causing a muscle contraction.
Myofilaments are the three protein filaments of myofibrils in muscle cells.
This depolarizes the muscle fiber membrane, and the impulse travels to the muscle's sarcoplasmic reticulum via the transverse tubules.
In the histology of skeletal muscle, a triad is the structure formed by a T tubule with a sarcoplasmic reticulum (SR) known as the terminal cisterna on either side.
Protein that in humans is encoded by the TCAP gene.
Telethonin is expressed in cardiac and skeletal muscle at Z-discs and functions to regulate sarcomere assembly, T-tubule function and apoptosis.
