Skeletal Muscle Organization Structure — NEET Biology
📚 Practice ConceptLet us examine a skeletal muscle in detail to understand the structure and mechanism of contraction. Each organised skeletal muscle in our body is made of a number of muscle bundles or fascicles held together by a common collagenous connective tissue layer called fascia. Each muscle bundle contains a number of muscle fibres. Each
Arrange the following in the correct sequence from smallest to largest structural unit of skeletal muscle: 1. Myofibril 2. Muscle fibre 3. Sarcomere 4. Fascicle 5. Whole muscle
View solution & NCERT explanation
Correct answer: A — 3 → 1 → 2 → 4 → 5
Sarcomere is the functional unit inside a myofibril. Many sarcomeres together form a myofibril. Several myofibrils are packed into a muscle fibre (cell). Groups of fibres form a fascicle, surrounded by connective tissue. Many fascicles together make up the whole skeletal muscle.
