  2. Long bone - Wikipedia

    en.wikipedia.org/wiki/Long_bone

    The long bones of the human leg comprise nearly half of adult height. The other primary skeletal component of height are the vertebrae and skull. The outside of the bone consists of a layer of connective tissue called the periosteum. Additionally, the outer shell of the long bone is compact bone, then a deeper layer of cancellous bone (spongy ...

  4. Bone - Wikipedia

    en.wikipedia.org/wiki/Bone

    Most bones of the limbs, including those of the fingers and toes, are long bones. The exceptions are the eight carpal bones of the wrist, the seven articulating tarsal bones of the ankle and the sesamoid bone of the kneecap. Long bones such as the clavicle, that have a differently shaped shaft or ends are also called modified long bones.

  5. Foot - Wikipedia

    en.wikipedia.org/wiki/Foot

    The hindfoot is composed of the talus (or ankle bone) and the calcaneus (or heel bone). The two long bones of the lower leg, the tibia and fibula, are connected to the top of the talus to form the ankle. Connected to the talus at the subtalar joint, the calcaneus, the largest bone of the foot, is cushioned underneath by a layer of fat. [2]

  6. Haversian canal - Wikipedia

    en.wikipedia.org/wiki/Haversian_canal

    Diagram of a typical long bone showing both cortical (compact) and cancellous (spongy) bone. Haversian canals [i] (sometimes canals of Havers, osteonic canals or central canals) are a series of microscopic tubes in the outermost region of bone called cortical bone. They allow blood vessels and nerves to travel through them to supply the osteocytes.

  7. Human musculoskeletal system - Wikipedia

    en.wikipedia.org/wiki/Human_musculoskeletal_system

    The number of bones varies according to the method used to derive the count. While some consider certain structures to be a single bone with multiple parts, others may see it as a single part with multiple bones. [5] There are five general classifications of bones. These are long bones, short bones, flat bones, irregular bones, and sesamoid bones.

  8. Epiphysis - Wikipedia

    en.wikipedia.org/wiki/Epiphysis

    These bones are located just beyond the wrist and serve as a link to the phalanges, or finger bones, at the end of the limbs. In the lower body, the femur is a prominent bone positioned between the hip and knee. As the longest bone in the human body, it plays a pivotal role in forming the upper part of the knee joint.

  9. Osteon - Wikipedia

    Diagram of a typical long bone showing both compact (cortical) and cancellous (spongy) bone. Osteons on cross-section of a bone. In osteology, the osteon or haversian system (/ h ə ˈ v ɜːr. ʒ ən /; named for Clopton Havers) is the fundamental functional unit of much compact bone.
