What is a cell membrane of a muscle fiber called?
what is the plasma membrane of the muscle cell
What is the plasma membrane of the muscle fiber?
The plasma membrane of a muscle fiber is called the sarcolemma. It surrounds the muscle cell and is responsible for controlling the passage of substances in and out of the cell, as well as transmitting signals for muscle contraction. The sarcolemma is essential for maintaining the integrity and function of the muscle fiber.
The plasma membrane of muscle cells is called the?
the sarcolemma encloses the muscle cell
When the chemically gated ion channels open which ion is mainly responsible for depolarizing the sarcolemma?
The main ion responsible for depolarizing the sarcolemma is sodium (Na+).
When acetylcholine diffuses across the synaptic cleft and binds to receptors on the folded sarcolemma it initaly causes what channels to open in the sarcolemma?
Acetylcholine binding causes nicotinic acetylcholine receptors on the folded sarcolemma to open, allowing the influx of sodium ions into the muscle cell. This initiates an action potential that propagates along the sarcolemma and into the T-tubules, triggering muscle contraction.
What is the irregular traverse thickenings of the sarcolemma that contain gap junctions which allow muscle action potentials to spread quickly from one cardiac muscle fiber to another?
Intercalated Discs
What are the tunnel-like extensions of the sarcolemma into the muscle fiber?
transverse tubules transverse tubules
What is name given to the regularly spaced infoldings of the sarcolemma?
transverse or T tubules
What connects the sarcolemma and the sarcoplasmic reticulum?
The T-tubules, or transverse tubules, connect the sarcolemma (muscle cell membrane) to the sarcoplasmic reticulum (membrane network within muscle cells). T-tubules allow for the rapid transmission of action potentials generated at the sarcolemma to the interior of the muscle cell, triggering the release of calcium from the sarcoplasmic reticulum to initiate muscle contraction.

Is sarcolemma a ligament?
No, the sarcolemma is the plasma membrane of a muscle cell.

The sarcolemma is essential for maintaining the integrity and function of the muscle fiber.
Is Sarcomere and sarcolemma the same thing?
sarcomere and sarcolemma are two different things. a sarcomere is between two d zisks of a myofiber (muscle fiber). a sarcolemma is a plasma membrane. there are many sections of sarcomere under the layer of sarcolemma.
The plasma membrane of muscle cells is called the?
the sarcolemma encloses the muscle cell
What is the treatment for sarcolemma?
Sarcolemma is defined as a thin membrane encasing a muscle fiber. This has no treatment as it is not an illness, injury or problem.
What are the thickenings that occur to the lenses of the eye affecting vision especially in the elderly?
cataracts
Where are acetycholine receptors found?
In the Sarcolemma
