⏱️ Save ~25 seconds

Fibrous = Skull sutures (immovable III); Cartilaginous = Intervertebral discs (limited movement I); Hinge = Knee joint (IV); Ball and socket = Shoulder / Humerus & Pectoral girdle (rotational II)! Match: A-III, B-I, C-IV, D-II!

1 A. Fibrous joints: Immovable joints between cranial bones of skull (III).

2 B. Cartilaginous joints: Joint between adjacent vertebrae permit limited movement (I).

3 C. Hinge joints: Synovial joint at knee helping in locomotion (IV).

4 D. Ball and socket joints: Between humerus and glenoid cavity of pectoral girdle permitting multiaxial rotational movement (II).

5 Matching order: A-III, B-I, C-IV, D-II -> Option (2) / B.

Step-by-Step Rigorous Workflow & Mathematical Proof

Step 1

Review Immovable and Slightly Movable Joints

Fibrous joints do not allow any movement. This type of joint is shown by the flat skull bones which fuse end-to-end with the help of dense fibrous connective tissues in the form of sutures (A -> III). In cartilaginous joints, the bones involved are joined together with the help of cartilages. The joint between the adjacent vertebrae in the vertebral column is of this pattern and it permits limited movements (B -> I).

Step 2

Review Synovial Joints and Mobility

Hinge joint (knee joint) permits movement primarily in one plane helping in walking/locomotion (C -> IV). Ball and socket joint between humerus and pectoral girdle allows rotational, wide-range movement (D -> II).

Step 3

Select Final Match

A-III, B-I, C-IV, D-II corresponds to Option (2).

⚠️

Student Fallacy (Why candidates pick this trap): Mismatches Fibrous joints with Knee.

4 (4)

✗ Incorrect

Verdict & Scientific Reason:

Mismatches Fibrous joints with vertebrae.

⚠️

Student Fallacy (Why candidates pick this trap): Mismatches Fibrous joints with vertebrae.

⚠️

NTA Trap Alert: Cartilaginous vs Synovial Movement

Thinking intervertebral joints are freely movable synovial joints.

🛡️ How to avoid the -1 mark: Intervertebral discs are cartilaginous (symphysis) allowing only limited, cumulative flexibility.
