Myasthenia gravis
skeletal muscle
Neuromuscular junction or neuromuscular synapse
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.
Curare acts by blocking nicotinic acetylcholine receptors at the neuromuscular junction, preventing the binding of acetylcholine to these receptors. This leads to muscle paralysis since acetylcholine is unable to initiate muscle contraction.
Neuromuscular blocking agents are medications that work by blocking the transmission of nerve signals to the muscles, resulting in muscle paralysis. They are used during surgical procedures to facilitate intubation, reduce muscle movements, and provide muscle relaxation. These medications are administered by anesthesiologists and require monitoring to prevent complications.

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.
This point is often called the neuromuscular junction or motor end plate. ?The neurotransmitter used here is acetylcholine.Many diseases occur with dysfunction at this junction, like Myesthenia Gravis, botulism, or Lambert Eaton Myasthenic Syndrome.
The axon terminals of a nerve cell and the sarcolemma of a skeletal muscle cell join at the neuromuscular junction. This is where the nerve impulse triggers the release of neurotransmitters, such as acetylcholine, which initiate muscle contraction by binding to receptors on the sarcolemma.
