Also known as a myocyte when referring to either a cardiac muscle cell , or a smooth muscle cell as these are both small cells.
This network is composed of groupings of two dilated end-sacs called terminal cisternae, and a single T-tubule (transverse tubule), which bores through the cell and emerge on the other side; together these three components form the triads that exist within the network of the sarcoplasmic reticulum, in which each T-tubule has two terminal cisternae on each side of it.
T-tubules (transverse tubules) are extensions of the cell membrane that penetrate into the centre of skeletal and cardiac muscle cells.
T-tubules in skeletal muscle are associated with two terminal cisternae, known as a triad.
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.
Together, two terminal cisternae and a transverse tubule form a triad.
Activation of tension-generating sites within muscle cells.
After this, cardiac muscle tends to exhibit diad structures, rather than triads.
Terminal cisternae are enlarged areas of the sarcoplasmic reticulum surrounding the transverse tubules.
A T-tubule surrounded by two terminal cisternae is called a triad.
Membrane contact sites (MCS) are close appositions between two organelles.
In muscle cells, at the triad, junctophilin, an integral ER membrane protein, is involved in ER-PM contact stabilization by interacting with PIPs in the PM.
