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.
1 A key function of nicotinic receptors is to trigger rapid neural and neuromuscular transmission. 2  Nicotinic receptors are found in: 3  The somatic nervous system (neuromuscular junctions in skeletal muscles).4  The sympathetic and parasympathetic nervous system (autonomic ganglia).ey Function of Nicotinic Receptors. The key function of nicotinic receptor proteins is to trigger rapid neural and neuromuscular transmissions. For those interested in learning about the molecular physiology of nicotinic receptors, the subject is discussed as optional reading below.
