Free Joints MCQs with Answers

• A. hinge joint
• B. ball and socket joint
• C. pivot joint
• D. gliding joint

Explanation: The rounded head of the femur sits in the cup shaped acetabulum, which allows movement in all planes plus rotation, the widest range any…

• A. Elbow
• B. Shoulder
• C. Hip
• D. Wrist

Explanation: The elbow is a hinge joint, so it permits flexion and extension but no rotation, in the same way as the knee and the joints of the…

• A. knee joint
• B. shoulder joint
• C. joint between the skull and the atlas
• D. joint between the atlas and the axis

Explanation: The atlas rotates around the odontoid process of the axis, and this pivot joint carries the skull with it.

• A. to lubricate the joint and nourish the articular cartilage
• B. to produce red blood cells
• C. to store calcium for the body
• D. to carry nerve impulses across the joint

Explanation: Synovial fluid is secreted by the synovial membrane into the joint cavity, where it reduces friction between the cartilage surfaces and…

• A. fibrous cartilage
• B. elastic cartilage
• C. calcified cartilage
• D. hyaline cartilage

Explanation: Hyaline cartilage is smooth, glassy and slightly compressible, so it lets bone ends slide over each other with very little friction while…

• A. No movement
• B. Presence of synovial fluid
• C. Cartilage only
• D. Fibrous capsule only

Explanation: Synovial joints (freely movable) contain synovial fluid for lubrication and nutrition of articular cartilage.

• A. Muscle to bone
• B. Bone to bone
• C. Muscle to muscle
• D. Cartilage to cartilage

Explanation: Ligaments connect bone to bone, providing joint stability. Tendons connect muscle to bone.

• A. Hinge
• B. Ball and Socket
• C. Cartilage
• D. Sutures

Explanation: A ball and socket joint such as the shoulder or hip allows movement in every plane including rotation, because the rounded head can turn…

• A. Elastic cartilage
• B. Fibrocartilage
• C. Costal cartilage
• D. Articular cartilage

Explanation: Fibrocartilage is tough and compressible, which suits a slightly movable joint that must bear load, and it is the same tissue found in the…

• A. Fibrous joints
• B. Immoveable joints
• C. Cartilaginous joints
• D. Freely moveable joints

Explanation: The pubic symphysis is a cartilaginous joint, its two bones joined by a pad of fibrocartilage that allows slight movement, which becomes…

• A. Epiglottis & intervertebral disc
• B. Trachea & intervertebral disc
• C. Nose & pinna
• D. Nose & trachea

Explanation: The C shaped rings of the trachea and the supporting plates of the nose are both hyaline cartilage, the smooth glassy type that also…

• A. Fibers
• B. Cells
• C. Laucane
• D. Blood capillaries

Explanation: Hyaline cartilage contains chondrocytes in lacunae and has fine collagen fibres embedded in a smooth matrix, but it is avascular and…

• A. Cartilage
• B. Charades
• C. Charcoal
• D. Chitin

Explanation: The external framework of the nose and the outer parts of the ears are supported mainly by cartilage, a flexible connective tissue that is…

• A. Suture
• B. Sutural joints
• C. Syndesmosis
• D. Both A and B

Explanation: A suture, also called a sutural joint, is an immovable fibrous joint between the flat bones of the skull.

• A. A compact bone.
• B. A spongy bone.
• C. Cartilage
• D. All of these

Explanation: Cartilage is avascular, meaning it has no direct blood vessels and receives nutrients by diffusion.

• A. Ligaments.
• B. Tendon
• C. Muscles.
• D. None of these

Explanation: Tendons are dense connective tissues with tightly packed collagen fibres and very little elasticity, allowing them to transmit muscle…

• A. Between radius and ulna.
• B. Between ulna and scapula
• C. Between humerus and scapula
• D. Between femur and tibia.

Explanation: The femur-tibia joint is the knee joint, a synovial hinge-type joint whose principal movements occur mainly in one plane.

• A. Synovial membrane.
• B. Ligaments.
• C. Muscles.
• D. Tendon

Explanation: The fibrous capsule of a synovial joint may become thickened into strong bands called ligaments, which reinforce and stabilise the joint.

• A. Fibrous joints.
• B. Cartilaginous joints.
• C. Synovial joints.
• D. None of these

Explanation: The suture between the two parietal bones is an immovable fibrous joint in which bones are connected by dense connective tissue.

• A. Immovable joint.
• B. Slightly movable joint.
• C. Freely movable joint.
• D. Fibrous joint

Explanation: The humerus, radius and ulna form the elbow, a synovial hinge joint that permits substantial movement, especially flexion and extension.
