Describe how the sliding filament model explains the
contraction of muscle fibers.
The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control. Smooth muscle fibers are found in walls of hollow visceral organs, except the heart, and appear spindle-shaped, this also works under involuntary control. The skeletal muscle fibers occur in muscles which are attached to the skeleton. They are striated in appearance and are under voluntary control. An action potential occurs when a neuron sends information down an axon, away from the cell body. The action potential is referred to as an explosion of electrical activity that is created by a depolarizing current.
