  2. Anatomical variation - Wikipedia

    en.wikipedia.org/wiki/Anatomical_variation

    Anatomical variations are mainly caused by genetics and may vary considerably between different populations. The rate of variation considerably differs between single organs, particularly in muscles. [2] Knowledge of anatomical variations is important in order to distinguish them from pathological conditions.

  3. Bone malrotation - Wikipedia

    en.wikipedia.org/wiki/Bone_malrotation

    Bone malrotation refers to the situation that results when a bone heals out of rotational alignment from another bone, or part of bone. It often occurs as the result of a surgical complication after a fracture where intramedullary nailing (IMN) occurs, [ 1 ] especially in the femur and tibial bones, but can also occur genetically at birth.

    The end regions of a long bone; regions of secondary ossification. epi-+ physis, "on top of the growth part" physis (epiphyseal plate) Also known as the growth plate. In a long bone it is a thin disc of hyaline cartilage that is positioned transversely between the epiphysis and metaphysis. In the long bones of humans, the epiphyseal plate ...

  6. Osteosclerosis - Wikipedia

    en.wikipedia.org/wiki/Osteosclerosis

    Osteosclerosis is a disorder characterized by abnormal hardening of bone and an elevation in bone density. It may predominantly affect the medullary portion and/or cortex of bone. Plain radiographs are a valuable tool for detecting and classifying osteosclerotic disorders. [1] [2] It can manifest in localized or generalized osteosclerosis.

  7. List of abnormal behaviours in animals - Wikipedia

    en.wikipedia.org/wiki/List_of_abnormal...

    Some abnormal behaviours may be related to environmental conditions (e.g. captive housing) whereas others may be due to medical conditions. The list does not include behaviours in animals that are genetically modified to express abnormal behaviour (e.g. reeler mice). A polar bear performing stereotyped pacing.

  8. Fibrous dysplasia of bone - Wikipedia

    en.wikipedia.org/wiki/Fibrous_dysplasia_of_bone

    Fibrous dysplasia is a very rare [2] nonhereditary genetic disorder where normal bone and marrow is replaced with fibrous tissue, resulting in formation of bone that is weak and prone to expansion. As a result, most complications result from fracture , deformity, functional impairment, pain, and the impingement of nerves. [ 3 ]

  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).
