What structure is part of a muscle cells membrane that delivers signals to sarcomere?

The transverse (T) tubules are structures in a muscle cell's membrane that deliver signals from the cell surface to the sarcomeres, which are the contractile units of the muscle cell. These T-tubules help coordinate muscle contraction by allowing the signal for muscle contraction to penetrate deeply into the cell.


Two terminal cisternae and a T- tubule?

This is a structure found in skeletal muscle cells known as a triad. It consists of two terminal cisternae (enlarged regions of the sarcoplasmic reticulum that store and release calcium ions) and a T-tubule (invagination of the sarcolemma that helps transmit action potentials deep into the muscle cell). The triad plays a crucial role in excitation-contraction coupling, where the action potential triggers the release of calcium ions for muscle contraction.


How does the membrane action potential get to the sarcoplasmic reticulum?

The membrane action potential triggers the release of calcium ions from the sarcoplasmic reticulum through a process called excitation-contraction coupling. This is mediated by the protein complex known as the ryanodine receptor, which allows calcium to flow out of the sarcoplasmic reticulum and into the cytoplasm upon stimulation by the action potential.


A tube formed by the inward extension of the cell membrane is called a?

A tube formed by the inward extension of the cell membrane is called a pseudopod. This structure is used by cells for processes such as engulfing particles or migrating.

What is a T-tubule?

A T-tubule is a small, tube-like invagination of the cell membrane in muscle cells, particularly in cardiac and skeletal muscle. T-tubules help to transmit action potentials quickly into the cell interior, allowing for synchronous contraction of muscle fibers.


What is the difference between a dyad and triad in skeletal cardiac muscle?

In skeletal muscle, a triad is formed when a T-Tubule is flanked on either side by the calcium containing Terminal Cisternae of the Sarcoplasmic Reticulum, at the level of the Z-line. The intimate association of these three membranous sturctures (Terminal Cisternae---T-Tubule---Terminal Cisternae) for a Triad. This differs from a diad (or Dyad), in cardiac muscle where the T-Tubule is only intimately associated with ONE Terminal Cisternae.
