Describe the basic process of skeletal muscle contraction, starting with the nerve ending that
meets the muscle cell, and ending with muscle fiber movement. - CORRECT ANSWER✔✔-
Nerve cells are located next to the muscle cells (the neuromuscular junction). An electrical
pulse travels from the spinal cord to the end of the nerve cell, where a neurotransmitter is
released and bonds to a receptor in the muscle fiber, causing an impulse. There's a
"wrapping" around the fiber called the sarcoplasmic reticulum that stores Calcium. The
impulse releases the Calcium ions. The Calcium ions enter the cytoplasm of the cell and bind
with compounds that couple actin and myosin together, called "excitation-contraction
coupling." When actin and myosin "grab" each other, the myofibrils contract and relax.
Calcium releases and moves back into the SR; actin and myosin "release" each other,
resulting in relaxation.
What does #2 represent? - CORRECT ANSWER✔✔- Z disc
