What are the components of the neuromuscular junction Biology Diagrams The neuromuscular junction (NMJ) is a synaptic connection between the terminal end of a motor nerve and a muscle (skeletal/ smooth/ cardiac). It is the site for the transmission of action potential from nerve to the muscle. It is also a site for many diseases and a site of action for many pharmacological drugs.[1][2][3][4] In this article, the NMJ of skeletal muscle will be discussed.
The neuromuscular junction is a synapse for the transmission of a signal from the motor nerve terminal to a postsynaptic region on the muscle fibre. It is the archetypal synapse, in the sense that it is so easy to identify and study that a lot of our understanding of synaptic neurotransmission comes from studies of neuromuscular synapses. The main molecular protagonist is acetylcholine, and it
Neuromuscular junction: Parts, structure and steps Biology Diagrams
A neuromuscular junction is a synapse between a motor neuron and skeletal muscle. Neuromuscular Junction anatomy. consists of the axon terminal of a motor neuron and the motor end plate of a muscle fibre. neurons communicate at junctions called. synapses = communication. The anatomy of a neuromuscular junction can be divided into three parts: the presynaptic terminal (i.e. the motor neuron) the synaptic cleft; the postsynaptic membrane (i.e. the membrane of the muscle cell). Presynaptic Terminal. A motor neuron has a dendritic end and an axonal end. The dendrites receive the signals from adjacent neurons Learn how neurons and muscles communicate through the neuromuscular junction, a type of synapse that uses acetylcholine as a neurotransmitter. Explore the anatomy, histology and clinical significance of this key component of the nervous system.
