Which bone disease is characterized by low bone mass and microarchitectural deterioration, increasing fracture risk?
Answer: Osteoporosis
Osteoporosis is defined by reduced bone mineral density and deteriorated bone microstructure, leading to fragility fractures with minimal trauma.
The synovial membrane lines which aspect of a joint?
Answer: The fibrous joint capsule inner surface
The synovial membrane lines the inner surface of the fibrous joint capsule and produces synovial fluid for joint lubrication and nutrition.
Which type of bone fracture in children occurs on one cortex only, with the other side bending but not breaking?
Answer: Greenstick fracture
A greenstick fracture affects one cortex while the opposite cortex bends, occurring in children whose bones are more flexible than adult bone.
Subluxation of a joint refers to which condition?
Answer: Partial displacement of joint surfaces with some contact remaining
Subluxation is an incomplete or partial dislocation where joint surfaces are misaligned but maintain some contact, distinguishing it from a full dislocation.
Which structure separates the epiphysis from the diaphysis in growing bone and is the site of longitudinal bone growth?
Answer: Physis (growth plate)
The physis, or growth plate, is the cartilaginous zone between the epiphysis and diaphysis where ossification drives longitudinal bone growth until skeletal maturity.
The patella is classified as which type of bone?
Answer: Sesamoid bone
The patella is the largest sesamoid bone in the body, embedded within the quadriceps tendon to improve mechanical advantage at the knee.
