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.
The acetylcholine diffuses across the synapse and binds to and activates nicotinic acetylcholine receptors on the motor end plate of the muscle cell. Activation of the nicotin â¦ ic receptor opens its intrinsic sodium/potassium channel, causing sodium to rush in and potassium to trickle out. 3 people found this useful.
