izomimpulzusok
Izomimpulzusok, often translated as muscle impulses or nerve impulses to muscles, refer to the electrical signals that travel along motor neurons to initiate muscle contraction. These impulses are fundamental to all voluntary and involuntary movements in the body. When a nerve cell, specifically a motor neuron, is stimulated, it generates an electrical impulse that propagates down its axon. This axon terminates at the neuromuscular junction, which is the specialized synapse between the motor neuron and a muscle fiber.
At the neuromuscular junction, the arrival of the electrical impulse triggers the release of neurotransmitters, most
This electrical signal ultimately leads to the release of calcium ions from the sarcoplasmic reticulum within
