Connective tissue in skeletal muscle

Each skeletal muscle consists of two kinds of tissue: connective tissue, and muscle tissue. Connective tissue of skeletal muscle contains:

The layers of connective tissue have a major role in protection and covering of muscle fibers, muscle fascicles, and an entire skeletal muscle. Tendons attach the skeletal muscles to bones. Aponeurosis is structurally as tendon that connects the muscles together, or to bone.

Layers of connective tissue[edit]

There are three layers of connective tissue in a skeletal muscle:

  • Epimysium
  • Perimysium
  • Endomysium

These layers are considered as part of each skeletal muscle.

Epimysium[edit]

The epimysium surrounds the whole skeletal muscle. This is the outer layer which protects and strengthens the skeletal muscle which at the end, surrounds the entire muscle

Perimysium[edit]

The perimysium encompasses the muscle fascicles. A fascicle contains a group of muscle fibers (or muscle cells). There are blood vessels and nerves in the perimysium to muscle fascicles.

Endomysium[edit]

The endomysium surrounds each single muscle fiber. A muscle fiber is known as a muscle cell. The endomysium separates the muscle fibers of a fascicle. This is a thin, delicate covering of connective tissue.

Layers of a tendon[edit]

Tendon is a dense connective tissue that attaches the muscle to bone, or to other muscles. Their collagen fibers contain the primary and secondary fascicles. The layers of connective tissue in each tendon from outside to inside include:

Features[edit]

Some Important characteristics of skeletal Connective tissue

  • Extensibility (ability to stretch)
  • Elasticity (ability to return to its original shape after stretching)
  • Providing each muscle a way to slide close to other structures, thus allowing for efficient movement that is unique and less affected by neighboring muscles and bone.
  • Irritability
  • Contractility (ability to contract)
  • and to assist in providing general structural integrity to all forms in the body
