It is a plain muscle or unstriated muscle and involuntary in nature. They are spindle shaped, 2.5 μ in diameter and 20 to 500 μ in length. Smooth muscle.
It is striated like skeletal muscle, but, involuntary in nature. The muscle fiber has branches and interdigitate with each other. Each fiber forms a separate.
Muscle fibers are innervated by the axons of motor neuron. Each axon supplies a single muscle fiber, forming one to one relationship called neuromuscular.
A motor neuron supplying a group of muscle fibers forms the motor unit. The number of muscle fibers innervated by the motor neuron varies depending upon.
Muscle shortening requires energy and this comes from the hydrolysis of ATP. The hydrolysis of ATP yields ADP, inorganic phosphate, and energy. The energy.
There are two types of muscle contractions, namely isotonic and isometric.In isotonic contraction, the muscle is allowed to shorten, but the tension in.
Skeletal muscle contraction is preceded by the excitation of the muscle by the nerve fiber. The events that occur from the point of excitation of the muscle.
the skeleton enables us to do voluntary movements. Skeletal muscle is covered by a connective tissue called epimysium. The muscle contains a number of.
