The muscle are biological motors which convert chemical energy into force and mechanical work.
This biological machinery is composed of proteins – which is actomyosin and the fuel is ATP.
With the use of muscles we are able to act on our environment.
Skeletal muscle is one of the three significant muscle tissues in the human body. Each skeletal muscle consists of thousands of muscle fibers wrapped together by connective tissue sheaths. The individual bundles of muscle fibers in a skeletal muscle are known as fasciculi.
Muscles is a contractile tissue which brings about movement.
Muscle cell responsible for our movement both visible and invisible, example walking, talking, bowel movement ,urination, breathing, heartbeats, the dilation and constriction of the pupils of our eyes and many other.
When we are still sitting or standing muscle cells keep us erect.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2. ORGANIZATION OF SKELETAL MUSCLE
• All activities that involve movement depend on muscles
• 650 muscles in the human body
• Various purposes for muscles for:
• Locomotion
• Upright posture
• Balancing on two legs
• Support of internal organs
• Controlling valves and body openings
• Production of heat
• Movement of materials along internal tubes
• Three types of muscles in the human body
• Skeletal
• Cardiac
• Smooth
3. ORGANIZATION OF SKELETAL
MUSCLE
•Skeletal muscles are muscles which are attached
to the skeleton.
•40% of human body mass
•Skeletal muscles are mainly responsible for
locomotion, and voluntary contraction and
relaxation.
4. ORGANIZATION OF SKELETAL
MUSCLE
•Muscle (whole organ)
•Fascicle (portion of muscle)
•Muscle Fiber (single muscle cell)
•Myofibril (muscle cell organelle)
•Sarcomere (portion of myofibril)
•Myofilament (part of sarcomere)
5. STRUCTURE OF SKELETAL MUSCLE
• Skeletal muscles are composed of clusters of muscle
cells.
•Muscle fibers
•Myofibers
•Myocytes
• A muscle consists of packages of muscle cells called
fascicles
• A muscle cell is long and spindle shaped
6. STRUCTURE OF SKELETAL MUSCLE
• Cell structure
• Muscles cells contain many nuclei
• The plasma membrane→ sarcolemma
• The cytoplasm→ sarcoplasm
• Length
• ranges from 0.1cm to more the 30cm in length
• Diameter
• ranges from 0.001cm to 0.01cm in diameter
• Myofibrils→
• elongated protein molecules
• aligned in parallel arrangements
• extend the full length of the cell.
9. STRUCTURE OF SKELETAL MUSCLE
• The myofibril consists of protein chains
called myofilaments.
• Myofilaments have a symmetrical,
alternating pattern of thick and thin
elements.
10. STRUCTURE OF SKELETAL MUSCLE
• Thick myofilament
• consists of a large number of bundled myosin molecules aligned in overlapping arrays.
• hexameric proteins with two identical heavy chains and two pairs of different light chains.
• regulatory light chain (RLC)
• essential light chain (ELC)
11. STRUCTURE OF SKELETAL MUSCLE
• The thin myofilament (F-actin, filamentous actin)
• made up of two helically intertwined chains of G-actin (globular actin)
units.
• Other proteins that bind to the actin molecules:
• Tropomyosin
• The Troponin complex→ made up of three members
12. PHYSIOLOGY OF MUSCLE
CONTRACTION
• SLIDING FILAMENT MECHANISM :
• The length of skeletal muscle shortens during contraction because the
thick and thin filaments slide over one another. The process is known
as the sliding filament mechanism.
• The thick filament contains 300 myosin molecules.
• It contain two parts:
1. Myosin tail
2. Myosin heads
• Myosin tail forms the shaft of the thick filament and heads projects
towards the thin filament.
• Thin filament contain actin, troponin and tropomyosin.
13. PHYSIOLOGY OF MUSCLE
CONTRACTION
• Myosin tail forms the shaft of the thick filament and heads projects
towards the thin filament.
• Thin filament contain actin, troponin and tropomyosin.
• At the onset of contraction, the sarcoplasmic reticulum release calcium
ions into cytosol
• There they bind to troponin and cause troponin-tropomyosin
complexes to move away from binding site on actin.
• Once the binding sites are free, the repeating sequence of events of the
contraction cycle occurs that causes the filaments to slide on each
other.
14. PHYSIOLOGY OF MUSCLE
CONTRACTION
• The contraction cycle consists of 4 steps
1. ATP hydrolysis.
2. Attachment of myosin to actin to form cross-bridges.
3. Power stroke.
4. Detachment of myosin from actin.
15. PHYSIOLOGY OF MUSCLE
CONTRACTION
1. ATP hydrolysis :
•The myosin head includes an ATP- binding site
and an ATPase, an enzyme that hydrolyses ATP
into ADP and phosphate group.
•This hydrolysis gives energy to myosin head.
•ADP and a phosphate group remain attached to
the myosin head.
16. PHYSIOLOGY OF MUSCLE
CONTRACTION
2. Attachment of myosin to actin to form cross-
bridges:
• The energized myosin head attaches to the myosin binding
site on actin and releases the previously hydrolyzed
phosphate group.
• When the myosin head attach to actin during contraction,
they are referred to as cross-bridges.
17. PHYSIOLOGY OF MUSCLE
CONTRACTION
3. Power stroke :
• Once the cross bridges are formed, the power stroke
occurs.
• The cross-bridge rotate towards the center of the
sarcomere and release the ADP molecule.
• The cross-bridge generates a force which slides the
thin filament over the thick filament.
18. PHYSIOLOGY OF MUSCLE
CONTRACTION
4. Detachment of myosin from actin:
• At the end of power stroke, the cross-bridge remains firmly
attached to actin until it binds another molecule of ATP.
• As ATP binds to the ATP binding site on the myosin head, the
myosin head detaches from actin.
