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 is the plasma membrane of the muscle fiber?
Sarcolemma
What is a cell membrane of a muscle fiber called?
what is the plasma membrane of the muscle cell
Is sarcolemma a ligament?
No, the sarcolemma is the plasma membrane of a muscle cell.
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.
What is the difference between endomysium and sarcolemma?
Sarcolemma is the equivalent of the plasma membrane of the muscle fiber (aka muscle cell). The endomysium is a connective tissue that bounds around the sarcolemma.
What connects the sarcolemma and the sarcoplasmic reticulum?
They connect to the transverse tubules of the the sarcolemma at triad junctions.
Where are acetycholine receptors found?
In the Sarcolemma
What is that thin membrane surrounding a muscle fiber called?
its called the plasma membrane or cell membrane. sometimes the semi-permeable plasma membrane. The Sarcolemma is the plasma membrane specifically surrounding a muscle fiber.
Irregular transverse thickenings of the sarcolemma?
Irregular transverse thickenings of the sarcolemma connect cardiac muscle fibers to neighboring muscle fibers. The gap junctions that occur with irregular transverse thickening of the sarcolemma allow the myocardium to contract as a single unit.
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+).
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.
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?
Chemically gated Na+ ions.
