The neuromuscular junction (NMJ) is the site of communication, a chemical synapse, between motor nerve axons and muscle fibers. This junction transmit ssignals from the motor neuron to the skeletal muscle fibre quickly and reliably. The goal is to ensure precise control of skeletal muscle contraction and therefore voluntary movement. The correct order of a signal being transmitted across a neuromuscular junction is the following: Neuron-neurotransmitter-receptor protein-motor end plate.
Answer:
Neuron - neurotransmitter - receptor protein - motor end plate
The answer about cardiovascular endurance is explained below.
Explanation:
When a body is doing a high intensity activity, the cardiorespiratory system works to provide oxygen to the muscles of the body. This ability of providing oxygen rich blood to the heart, blood vessels and lungs efficiently, is called as the Cardiovascular endurance.
