Muscle

Smooth Muscle
Smooth Muscle

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.

Cardiac Muscle
Cardiac 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.

Neuromuscular Transmision
Neuromuscular Transmision

Muscle fibers are innervated by the axons of motor neuron. Each axon supplies a single muscle fiber, forming one to one relationship called neuromuscular.

Motor Unit
Motor Unit

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.

Energy Mechanism During Muscle Contraction
Energy Mechanism During Muscle Contraction

Muscle shortening requires energy and this comes from the hydrolysis of ATP. The hydrolysis of ATP yields ADP, inorganic phosphate, and energy. The energy.

Mechanics Of Muscle Contraction
Mechanics Of Muscle Contraction

There are two types of muscle contractions, namely isotonic and isometric.In isotonic contraction, the muscle is allowed to shorten, but the tension in.

Molecular Events During Muscular Contraction
Molecular Events During Muscular Contraction

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.

Skeletal Muscle
Skeletal 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.
