The junction between a motor neruon's axon and the muscle cell membrane is called a neuromuscular junction or a myoneuraljunction?
Junctions among epithelial cells lining the digestive tract.

binding of acetylcholine to membrane receptors on the sarcolemma
At a neuromuscular junction, the motor neuron terminal and the muscle fiber membrane (sarcolemma) approach each other. The motor neuron releases the neurotransmitter acetylcholine, which binds to receptors on the muscle fiber membrane, initiating muscle contraction.
neuromuscular junction
The neurotransmitter used at the neuromuscular junction is acetylcholine. It is released from the motor neuron terminals and binds to receptors on the muscle cell membrane, leading to muscle contraction.
A gap junction forms when a channel is created between two adjacent plasma membranes. This type of cellular junction allows for direct communication and passage of small molecules between the two cells.
The chemical used at the junction with a skeletal muscle is acetylcholine (ACh). It is released from the motor neuron at the neuromuscular junction and binds to receptors on the muscle fiber's membrane, triggering muscle contraction. This process is essential for voluntary movement and is part of the overall neuromuscular signaling mechanism.
