A motor neuron and all of the skeletal muscle cells it stimulates is called a motor unit. The axon of each motor neuron has numerous endings called axonal terminals. The actual gap between an axonal endings and the muscle cell is called a synaptic cleft. Within the axonal endings are many small vesicles containing a neurotransmitter substance called __________.

When the _________ reaches the end of the axon, the neurotransmitter is released, and it diffuses to the muscle cell membrane to combine with receptors there.

When the nerve impulse reaches the end of the axon, the neurotransmitter is released, and it diffuses to the muscle cell membrane to combine with receptors there. Binding of the neurotransmitters with muscle membrane receptors cause the membrane to become permeable to sodium, resulting in the influx of sodium ions and ________ of the membrane. Then contraction of the muscle cell occures.

"Acetylcholine is released into the neuromuscular junction by the axonal terminal" is the _______ step out of seventh in muscular contraction in a skeletal muscle cell.

"The action potential, carried deep into the cell, causes the sarcoplasmic reticulum to release calcium ions." is the ______ step out of seventh in muscular contraction in a skeletal muscle cell.

"The muscle cell relaxes and lengthens" is the ______ step out of seventh in muscular contraction in a skeletal muscle cell.

"Acetylcholine diffuses across the neuromuscular junction and binds to receptors on the sarcolemma." is the _______ step out of the seventh in muscular contraction in a skeletal muscle cell.

"The calcium ion concentration at the myofilaments increases; the myofilaments slide past one another, and the cell shorts." is the _______ step out of the seventh in muscular contraction in a skeletal muscle cell.

"Depolarization occurs, and the action potential is generated." is the ________ step out of the seventh in muscular contraction in a skeletal muscle cell.

"As calcium is actively reabsorbed into the sarcoplasmic reticulum, its concentration at the myofilaments decreases." is the ________ step out of the seventh in muscular contraction in a skeletal muscle cell.

What region of the sarcomere shortens during contraction Light or Dark band?

There is a greater concentration of NA+ Outside the cell, and there is a greater concentration of K+ Inside the cell. When the stimulus is delivered, the permeability of the membrane is changed, and NA+ diffuses into the cell, initiating the depolarization of the membrane. Almost as soon as the depolarization wave begins, a repolarization wave follows it across the membrane. This occurs as K+ diffuses out of the cell. Repolzarization restores the Electrical conditions of the resting cell membrane. The Relative ionic concentrations on the 2 sides of the membrane during rest.
