How does the membrane action potential get to the sarcoplasmic reticulum?
It travels down a T-tubule.
A tube formed by the inward extension of the cell membrane is called a?
Sieve tube
A folded region of the sarcolemma at the neuromuscular junction?
At the neuromuscular junction (or presynaptic end) of the sarcolemma, it is referred to as end plate synapse potential.
Are T and b cells are two types of phagocytes?
T and B cells are two types of lymphatic cells.
What would happen if acetylcholine was released into a neuromuscular junction?
It attaches to its receptor, and binds. Causes another action potential, (calcium released) and it goes to the T-tubule of the Sarcoplasmic reticulum, and attaches to troponin, which moves the tropomyosin, so the myosin and actin and attach, and cause a muscle contraction.
What is formed by a t tubule and two adjacent terminal cisternae?
Triad
The triads of a muscle fiber consist of?
Two terminal cisternae and a T-tubule
The skeletal muscle complex known as the triad consists of what?
one transverse tubule and two terminal cisternae
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.
What event most directly triggers the release of calcium from the terminal cisternae?
action potential propagating down the T tubule
The enlarged perpendicular chambers of the sarcoplasmic reticulum that store calcium ions lies adjacent to the t tubule at the you band and the a band interface of the skeletal muscle sarcomere?
It is the terminal cisternae
What conducts muscle impulses deep in the sacroplasm of a muscle to the cisternae?
I believe the T-Tubule
Terminal cisternae of the sarcoplasmic reticulum release Ca2 when signaled by the?
T tubules
What does a muscle triad include?
For skeletal muscle, a triad includes a T tubule with a sarcoplasmic reticulum and a terminal cisterna on either side. Within a muscle fiber there are thousands of triads.
What is a T-tubule?
To carry an action potential to the interior of the cell.
What organelle releases calcium ions when an electrochemical message moves down a T-tubule?
Terminal cisterns of the sarcoplasmic reticulum through the Rhynodine receptors release calcium into the skeletal muscle cell when stimulated by an action potential.
How does the membrane action potential get to the sarcoplasmic reticulum?
It travels down a T-tubule.
