Evidence for the use of low frequency ultrasound to treat wounds is limited and consists of studies that lack adequate. sample sizes and proper control groups. Additional research with larger trials is needed to demonstrate that low. frequency ultrasound is beneficial for health outcomes in patients with wounds.
The neurotransmitter, acetylcholine, once it has diffused into the synapse, binds to the nicotinic acetylcholine receptors, which are found in the motor end plate. These receptors are ligand-gated ion channels, and once acetylcholine has binded to the receptors, it causes the channels to open.
Calcium triggers the release of acetylcholine from the neuron. Acetylcholine then crosses the synapse and binds to acetylcholine receptors on the muscle cell membrane. Like a key in a lock, acetylcholine opens sodium ion channels that depolarize and excite the muscle membrane.he space between the motor neuron and the skeletal muscle cell is simply referred to as a synapse. More specifically, the synapse between a motor neuron and a skeletal muscle cell is referred to as a myoneural or neuromuscular junction.
