skjelettsystem
The skjelettsystem, or skeletal system in English, is a complex biological structure that provides support, protection, and movement for the body. Composed primarily of bones, cartilage, and connective tissues, it plays a crucial role in maintaining the body’s shape and facilitating physical activity. In humans, the skeletal system consists of approximately 206 bones, which vary in size, shape, and function. These bones are categorized into two main types: axial (forming the central axis of the body, including the skull, spine, and rib cage) and appendicular (comprising the limbs and girdles).
Bones serve multiple essential functions beyond structural support. They act as a mineral reservoir, storing calcium
Cartilage, a flexible connective tissue found in areas like the ears, nose, and between bones in joints,
Development of the skeletal system begins during fetal growth and continues through childhood, with bones initially
Diseases and conditions affecting the skeletal system include fractures, osteoporosis (a condition characterized by weakened bones),
