Development and Aging of Skeletal Systems Quiz

Vertebrae are part of the axial skeleton and contain red bone marrow, where blood cells are produced.

Ossification is the process by which bones are formed, involving the deposition of calcium salts.

Ball-and-socket joints allow for the widest range of motion in all directions.

Parathyroid hormone regulates blood calcium levels by stimulating bone resorption and increasing calcium absorption in the intestines.

Collagen is the main protein component of the bone extracellular matrix, providing strength and flexibility.

The skeletal system provides structural support and protects vital organs.

Growth hormone stimulates bone growth and development, particularly during childhood and adolescence.

Vitamin D is essential for the absorption of calcium in the bones, aiding in bone mineralization.

Synovial fluid lubricates and cushions the joints, reducing friction and providing shock absorption.

Scoliosis is a condition characterized by an abnormal sideways curvature of the spine.

Osteoporosis is a condition characterized by low bone density, resulting in weak and brittle bones.

A decrease in collagen production is a factor contributing to the aging of the skeletal system, leading to weaker bones.

Rheumatoid arthritis is an autoimmune disorder causing inflammation in the joints and surrounding tissues.

Wolff's Law states that bones remodel and adapt in response to the stress and loads placed upon them.
