• A. Healing properties.
• B. Destructive properties.
• C. Neutralizing properties.
• D. Dead cells

Explanation: A fracture hematoma contains pooled blood, damaged tissue and dead cells produced when blood vessels and bone are torn.

• A. They are more common than in adult age.
• B. Occur as a result of bone being thin and weak.
• C. Due to good blood supply it results in quick healing.
• D. It involves osteoblasts and osteocytes.

Explanation: Fractures heal more slowly in old age because bone is weaker and repair activity and blood supply are generally reduced, not improved.

• A. It results from estrogen deficiency.
• B. Bone eating process takes over bone formation process.
• C. There is reduction of bone mass and change in chemical composition of the matrix
• D. It is common in old age.

Explanation: Osteoporosis reduces bone mass, but the remaining bone matrix generally has normal chemical composition; its amount and microscopic…

• A. Hypocalcaemia Tatanic spasms.
• B. Osteomalacis.
• C. Rickets.
• D. Tetany

Explanation: Calcium deficiency during childhood weakens the developing bones and causes rickets, often with bowed legs and poor mineralisation.

• A. 5
• B. 7
• C. 9
• D. 12

Explanation: The cervical region of the human vertebral column contains seven vertebrae, labelled C1 to C7.

• 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.

• A. Fibrous joints
• B. Cartilaginous joints
• C. Synovial Joints
• D. Slightly moveable joints

Explanation: The joints between the bones of the skull are sutures, in which the bones are joined by dense fibrous connective tissue, so they are…

• A. Acidic acid
• B. Butyric acid
• C. Citric acid
• D. Lactic acid

Explanation: During intense exercise, oxygen delivery may not meet demand, so muscle cells rely more on anaerobic glycolysis and convert pyruvate to…

• A. Hypocalcemia
• B. Hypercalcemia
• C. Clostridum tetani.
• D. Low O2 level

Explanation: Tetany is caused by hypocalcemia, or a reduced concentration of calcium ions in the blood, which increases nerve and muscle excitability…

• A. The major event in it is accumulation of lactic acid.
• B. Lactic acid accumulation turns pH in acidic range leading to muscle ache.
• C. Ionic imbalance may also cause it.
• D. All of these

Explanation: Muscle fatigue may involve lactate and hydrogen ion accumulation, changes in pH, and ionic disturbances that interfere with excitation and…

• A. Accunulation of rigid proteins molecules in sarcoplam.
• B. Unavailability of ATP, which is necessary to break the link between actin and myosin.
• C. Decrease in body temperature after death.
• D. Death of tissue due to unavailability of O2.

Explanation: After death, ATP production stops, so myosin heads cannot detach from actin because ATP is required for their release.

• A. Z- lines get closer
• B. A band becomes short
• C. 1 band elongates
• D. There is no change in sarcomere

Explanation: During contraction, actin slides over myosin without either filament changing length, bringing the two Z-lines closer together.
