Skeletal muscle is one of three muscle types (the others are smooth and cardiac) and is striated, voluntary, and usually attached to bones. A muscle is made of bundles called fascicles, each containing long, cylindrical muscle fibres enclosed by a plasma membrane, the sarcolemma, surrounding sarcoplasm packed with numerous myofibrils. Each myofibril shows alternating dark and l

1. Skeletal muscle and mechanism of contraction
Exam focus: The sliding filament model's classic trap is which band changes: during contraction the A band (myosin's length) stays constant while the I band and H zone shrink as actin slides inward — the filaments don't shorten, the sarcomere does. ATP is needed not just for the power stroke but to detach the myosin head from actin afterward, which is why its absence after death causes rigor mortis.

ZoologyNEET 2023show ▾Which of the following statements are correct regarding skeletal muscle?
A. Muscle bundles are held together by a collagenous connective tissue layer called the fascicle.
B. The sarcoplasmic reticulum of the muscle fibre is a store house of calcium ions.
C. The striated appearance of the skeletal muscle fibre is due to the distribution pattern of actin and myosin proteins.
D. The M line is considered the functional unit of contraction, called the sarcomere.

2. Skeletal system and joints
Exam focus: The skeleton's numbers are exact and tested as-is: 206 bones total, split into 80 in the axial skeleton (skull, vertebral column, ribs, sternum) and 126 in the appendicular skeleton (limbs and girdles). Among joints, NEET likes naming the less obvious synovial types by example — the saddle joint between the thumb's carpal and metacarpal, not just the familiar hinge and ball-and-socket.

- D.A-IV, B-II, C-III, D-I
Solution
Fibrous joints in the skull allow no movement (III); cartilaginous joints between vertebrae allow limited movement (I); the knee is a hinge joint (IV); the shoulder (humerus–pectoral girdle) is a ball-and-socket joint allowing rotation (II).

3. Disorders
Exam focus: The muscular-disorder pair NEET likes to swap is myasthenia gravis (autoimmune — antibodies attack acetylcholine receptors at the neuromuscular junction, causing fatigue) against muscular dystrophy (genetic, progressive degeneration of skeletal muscle, no immune component at all). Tetany is a different mechanism again — spasms from low blood Ca2+, not muscle wasting.
