  2. Human musculoskeletal system - Wikipedia

    en.wikipedia.org/wiki/Human_musculoskeletal_system

    The skeletal system serves many important functions; it provides the shape and form for the body, support and protection, allows bodily movement, produces blood for the body, and stores minerals. [4] The number of bones in the human skeletal system is a controversial topic.

  3. Human skeleton - Wikipedia

    en.wikipedia.org/wiki/Human_skeleton

    It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. [1] The bone mass in the skeleton makes up about 14% of the total body weight (ca. 10–11 kg for an average person) and reaches maximum mass between the ages of 25 and 30. [ 2 ]

  4. Human body - Wikipedia

    en.wikipedia.org/wiki/Human_body

    The human body consists of many interacting systems of organs. These interact to maintain homeostasis, keeping the body in a stable state with safe levels of substances such as sugar and oxygen in the blood. [58] Each system contributes to homeostasis, of itself, other systems, and the entire body. Some combined systems are referred to by joint ...

  5. Bone resorption - Wikipedia

    en.wikipedia.org/wiki/Bone_resorption

    Bone tissue is a dynamic system with active metabolism. [24] Bone tissue remodelling or bone remodeling is a successive chain of old bone matrix removal and its replacement with a new one. [25] These processes make a child’s skeleton grow and extend, while childhood is characterized by bone tissue growth rather than its resorption.

  6. Joint - Wikipedia

    en.wikipedia.org/wiki/Joint

    A joint or articulation (or articular surface) is the connection made between bones, ossicles, or other hard structures in the body which link an animal's skeletal system into a functional whole. [1] [2] [3] They are constructed to allow for different degrees and types of movement.

  7. Ligament - Wikipedia

    en.wikipedia.org/wiki/Ligament

    A ligament is the fibrous connective tissue that connects bones to other bones. It also connects flight feathers to bones, in dinosaurs and birds. All 30,000 species of amniotes (land animals with internal bones) have ligaments. It is also known as articular ligament, articular larua, [1] fibrous ligament, or true ligament.

  8. Bone - Wikipedia

    en.wikipedia.org/wiki/Bone

    In the human body at birth, approximately 300 bones are present. Many of these fuse together during development, leaving a total of 206 separate bones in the adult, not counting numerous small sesamoid bones. [3] [4] The largest bone in the body is the femur or thigh-bone, and the smallest is the stapes in the middle ear.

  9. Bone remodeling - Wikipedia

    en.wikipedia.org/wiki/Bone_remodeling

    Bone tissue is removed by osteoclasts, and then new bone tissue is formed by osteoblasts. Both processes utilize cytokine (TGF-β, IGF) signalling.In osteology, bone remodeling or bone metabolism is a lifelong process where mature bone tissue is removed from the skeleton (a process called bone resorption) and new bone tissue is formed (a process called ossification or new bone formation).
