Previous Year Papers NEET Biology Class 11 – Locomotion and Movement

Locomotion and Movement is an essential chapter of NEET Biology Class 11 that explains the structure and function of the human skeleton, types of muscles, and mechanism of movement at joints. Mastering this chapter is crucial for both theoretical and diagram-based NEET questions.

NEET previous year papers frequently include questions on skeletal bones, joints, muscle types, and muscle contraction mechanisms. Practicing PYQs helps students strengthen understanding of human movement and related anatomy. Studentbro.in provides exam-focused material for effective preparation.

Human Skeletal System – NEET PYQ Focus

The human skeleton consists of axial (skull, vertebral column, ribs) and appendicular (limbs, girdles) components. It provides support, protection, and attachment for muscles.

NEET questions often test identification of bones, structural features, and differences between axial and appendicular skeletons.

Types of Joints – Important NEET Concepts

Joints are connections between bones that allow movement. Types include:

• Fibrous Joints – Immovable (e.g., sutures of skull).

• Cartilaginous Joints – Slightly movable (e.g., intervertebral discs).

• Synovial Joints – Freely movable (e.g., shoulder, knee, elbow).

Previous year papers frequently ask about joint structure, synovial fluid, ligaments, and types of movements (flexion, extension, rotation).

Muscular System – NEET Conceptual Questions

Muscles are responsible for movement. Major types include:

• Skeletal Muscles – Voluntary, striated, attached to bones.

• Smooth Muscles – Involuntary, non-striated, present in internal organs.

• Cardiac Muscle – Involuntary, striated, present in heart.

NEET questions often include structural differences, functions, and examples of each muscle type.

Mechanism of Muscle Contraction

Muscle contraction occurs via sliding filament theory. Actin and myosin filaments slide past each other, shortening sarcomeres and generating movement. ATP and calcium ions are essential for contraction.

NEET PYQs often include steps of contraction, energy requirement, and diagram-based labeling of sarcomere.

Movement at Joints

Movement at joints occurs due to contraction and relaxation of skeletal muscles. Types include flexion, extension, abduction, adduction, rotation, and circumduction.

Previous year questions frequently test types of movement at specific joints (e.g., ball and socket, hinge, pivot).

Disorders Related to Locomotion

Common disorders include arthritis, osteoporosis, muscular dystrophy, and myasthenia gravis. NEET questions may include causes, symptoms, and preventive measures.

Importance of Previous Year Papers for NEET Biology

Practicing previous year papers helps students identify frequently asked topics, reinforce conceptual understanding, and improve speed. PYQs for Locomotion and Movement focus on bones, joints, muscles, and contraction mechanisms, which are commonly tested in NEET.

Conclusion

Previous Year Papers of NEET Biology Class 11 Locomotion and Movement are essential for mastering human anatomy and physiology. This chapter requires clear understanding of skeletal system, muscle types, joint movements, and mechanisms of muscle contraction.

Regular practice of PYQs helps students enhance conceptual clarity, diagram interpretation, and confidence in NEET. Studentbro.in provides structured, reliable, and exam-focused content to help NEET aspirants succeed.
