Structure and Function of Skeletal Muscles

Answer 1

Structurally, the skeletal muscle consists of a large number of muscle fibres and a connective tissue framework organized as :

• Each muscle fibre is surrounded by a delicate connective tissue called endomysium which contains large quantity of elastic tissue arranged longitudinally.
• The muscle fibres are grouped into a number of bundles called fasciculi. Each fasciculus is surrounded by a stronger sheath of connective tissue called perimysium.
• All the fasciculi collectively form the muscle belly. The connective tissue that surrounds the entire muscle belly is called epimysium.
• At the junction of the muscle with its tendon, the fibres of endomysium, perimysium and epimysium become continuous with the fibres of the tendon.
• Tendons are fibrous terminal ends of the muscles made up of collagen fibres.   
  

Functions:

1. Produce skeletal movement.

2. Maintain body posture and position.

3. Supports the soft muscle tissues

4. Guard the enterance and exit .

5. Maintain body temperature.

6. Store nutrient reserves.
