Skeletal and Muscular System

Body height is determined by epiphyseal or growth plate.

A ligament is a flexible, dense fibrous connective tissue that connects bones to other bones or bones to cartilage. They provide stability and limit excessive movement at joints. Xylem transports water in plants, bone is hard tissue, and tendons connect muscle to bone.

Osteoma is a benign neoplasm and is characterised by a proliferation of either compact or cancellous bone, usually in an endosteal or periostial location.

The human pelvis has several distinctive features: deep concavity (acetabulum), broad structure to support abdominal organs, and expanded ilium (the upper, wing-shaped portion). These adaptations are related to bipedal locomotion and organ support.

Bone cells are embedded in a hard matrix that is composed of calcium and phosphorus compounds

Two bones can be connected to each other by another type of connective tissue called the ligament.

The bregma is known as anterior fontanelle during infancy.

Common peroneal nerve dysfunction is due to damage to the peroneal nerve resulting in the loss of movement in the foot and leg. It supplies movement and sensation to the lower leg, foot and toes. When Raman met with an accident and had a fracture at the neck of fibula, the common peroneal nerve must have been damaged.

The entire skeleton of cartilaginous fishes (sharks, rays, skates) is composed of hyaline cartilage, which is a flexible, translucent cartilage type. Unlike bony fishes, their skeletons never ossify into bone. Hyaline cartilage provides both structural support and flexibility, allowing these fishes to maintain their streamlined shape while being lightweight.

The pygostyle is the fused terminal caudal vertebrae in birds, forming a supportive structure for tail feathers and tail muscles. It is not found in frogs or rabbits - their tails contain unfused vertebrae or different skeletal structures.

Violent inversion of the foot causes avulsion fracture of the 5th metatarsal tuberosity because the peroneus brevis tendon inserts there. This injury is common in ankle inversion injuries and is sometimes called a 'Jones fracture' though true Jones fractures are more proximal.

Perforating veins connect superficial to deep venous systems and are found throughout the lower limb (ankle, calf, thigh). However, they are absent below the inguinal ligament in the region of the saphenofemoral junction, making this the correct answer.

Hyaline cartilage is composed primarily of Type II collagen, which provides tensile strength to the cartilage matrix. This is distinct from Type I collagen (found in bone and tendons), Type III collagen (reticular fibers in soft tissues), and Type IV collagen (basement membranes). The Type II collagen is characteristic of all hyaline cartilage including articular surfaces.

Canaval sign (likely a variant or regional term for Finkelstein's maneuver/test) is used to diagnose de Quervain's tenosynovitis. The test involves flexing the thumb into the palm, grasping it with the fingers, and then ulnarly deviating the wrist. Pain over the radial styloid process indicates a positive test, suggesting inflammation of the abductor pollicis longus and extensor pollicis brevis tendons. Dupuytren's contracture involves palmar fascia, carpal tunnel involves median nerve compression, and trigger finger involves flexor tendon locking.
