The sites where a chemical substance is transmitted from the presynaptic terminal of an axon to the postsynaptic membrane of a muscle fiber are called neuromuscular junctions. At these junctions, the neurotransmitter acetylcholine is released from the presynaptic terminal and binds to receptors on the postsynaptic membrane, initiating muscle contraction.
Acetylcholine is the chemical that transmits signals across the neuromuscular junction. It binds to receptors on the muscle cell membrane, leading to muscle contraction.
Muscle cells generate potential difference through the movement of charged ions across their membrane. This is achieved by opening and closing ion channels in response to stimuli, such as nerve signals or changes in membrane potential. The movement of ions, such as sodium and potassium, creates an imbalance in charge that results in a potential difference across the cell membrane, which is essential for muscle contraction.
Acetylcholine is the primary chemical transmitter released at the neuromuscular junction. It binds to acetylcholine receptors on the muscle cell membrane, leading to muscle contraction.

The way in which alcohol destroys muscle tissue is still not well understood. Proposed mechanisms include muscle membrane changes affecting the transport of calcium, potassium, or other minerals; impaired muscle energy.
Acetylcholine is the chemical that transmits signals across the neuromuscular junction. It binds to receptors on the muscle cell membrane, leading to muscle contraction.
Acetylcholine binds to the muscle cell membrane, causing a temporary rush of calcium ions into the muscle cell. This influx of calcium triggers muscle contraction.
The combining of the neurotransmitter with the muscle membrane receptors causes the membrane to become permeable to sodium ions and depolarization of the membrane. This depolarization triggers an action potential that leads to muscle contraction.
Yes, even though the human membrane is not a muscle.
The graded potential generated along the muscle cell membrane is known as an action potential. This is an electrical signal that travels along the membrane of the muscle cell, leading to muscle contraction. It is initiated by the movement of ions across the membrane in response to a stimulus.

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.
Ability to conduct impulses along the muscle membrane.
sarcolemma is the plasma membrane of the muscle fiber (muscle cell)
