Sarcolema receptors
The neurotransmitter acetylcholine is released into the synaptic cleft to bind with receptors on muscle cells. Upon binding, the muscle cells contract.
It blocks the nicotinic cholinergic receptors on the muscle that normally bind the acetylcholine released by the motor neuron.
Organopesticides will increase the severity of muscle contraction beyond normal conditions. Acetylcholine esterase inhibition will allow a more than normal amount of acetylcholine to bind to receptors.
acetylcholine as far as i know is a neurotransmitter that ativates the mscle cells.
Acetylcholine.
The presence of an enzyme called acetylcholinesterasethat degrades acetylcholine is what prevents an accumulation of the neurotransmitter and sustained muscle contraction. Acetylcholinesterase is an enzyme that can be found within the neuromuscular junction. Thus, when a nerve impulse causes the release of acetylcholine at the neuromuscular junction, there is a critical time in which the neurotransmitter can bind to receptors on the muscle before it is degraded.
acetylcholine (ACh)
tendons - bind muscle to muscle ligaments- bind muscle to bone
Acetylcholine is the excitatory neurotransmitter released by neurons innervating skeletal muscles. Acetylcholine release stimulates muscle contraction by acting at the nicotinic-acetylcholine receptor on the surface of the muscle cell.
nicotinic and muscarinic
