Neuromuscular junction A neuromuscular junction (sometimes called a myoneural junction) is a junction between nerve and muscle; it is a chemical synapse formed by the contact between the presynaptic terminal of a motor neuron and the postsynaptic membrane of a muscle fiber.ChRs at the skeletal neuromuscular junction form heteropentamers composed of two α, one β, one ɛ, and one δ subunits. When a single ACh ligand binds to one of the α subunits of the ACh receptor it induces a conformational change at the interface with the second AChR α subunit.

Answer this questWhen the motor neuron releases acetylcholine into  the neuromuscular junction, the acetylcholine binds to receptors in  the muscle fiber that allows positiv…ely charged ions to enter the  muscle fiber, which results in the muscle fiber contracting. 6 people found this useful.

What is a Neuromuscular Junction? Adorable animal families that will make you aww. A neuromuscular junction is a place in the body where the axons of motor nerves meet the muscle, allowing them to transmit messages from the brain that cause the muscle to contract and relax.Every organism has thousands of these junctions that control the movements of the body and cause the heart to beat.n the instance of a neuromuscular junction, one neuron can control many muscle cells, but each muscle cell only responds to one neuron. At this junction, the motor neuron meets muscle tissue at an axion terminal.

Skeletal Muscle Anatomy & Physiology. THE ROLE OF THE NEUROMUSCULAR JUNCTION IN MUSCLE CONTRACTION. As the axon of a motor neuron approaches a muscle that it innervates, it divides into multiple branches, each of which makes a synapse called a neuromuscular junction with an individual muscle fibre. It thus follows that any one muscle fibre is innervated by only one motor neuron.

Describe the ionic and other events leading up to the release of neurotransmitter at the vertebrate neuromuscular junction. The motor end plate is the highly-excitable region of muscle fiber plasma membrane responsible for initiation of action potentials across the muscle's surface, ultimately causing the muscle to contract. In vertebrates, the signal passes through the neuromuscular junction via the neurotransmitter acetylcholine. The neuromuscular junction is the location where the neuron activates muscle to contract, by releasing neurotransmitter.

Neuromuscular Junction Neuromuscular junction can be defined as a synapse the motor neuron and the muscle fiber. Actually the synapse occurs between the “synaptic end bulbs” of the motor neuron and “motor end plate ” of muscle fiber.ynaptic end bulbs: As the axon of the motor neuron enters the skeletal muscle, it forms many branches called axon terminals. At the end of each axon terminal, there is a bulbous swelling called “synaptic end bulb”.

- A neuromuscular junction (sometimes called a myoneural junction) is a junction between nerve and muscle; it is a chemical synapse formed by the contact between the presynaptic terminal of a motor neuron and the postsynaptic membrane of a muscle fiber.he binding of ACh to the receptor can depolarize the muscle fiber, causing a cascade that eventually results in muscle contraction. Neuromuscular junction diseases can be of genetic and autoimmune origin.

Neuromuscular Junction Synaptic cleft is the space between the motor end plate (muscle fiber part) and synaptic end bulb (motor neuron part) of the neuromuscular junction. It is 20 to 30 nanometers wide. Because of this cleft, the connection between the motor neuron and the muscle fiber is not continuous and there is a break.ifference between synapse and neuromuscular junction: Synapses and neuromuscular junctions are physiologically the same, however, the neuromuscular junction is a specific type of synapse that occurs between motor neuron and muscle fiber.
