  2. Osteon - Wikipedia

    en.wikipedia.org/wiki/Osteon

    The Haversian canal contains the bone's blood supplies. The boundary of an osteon is the cement line. Each Haversian canal is surrounded by varying number (5-20) of concentrically arranged lamellae of bone matrix. Near the surface of the compact bone, the lamellae are arranged parallel to the surface; these are called circumferential lamellae.

  3. 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.

  4. Volkmann's canal - Wikipedia

    en.wikipedia.org/wiki/Volkmann's_canal

    Volkmann's canals, also known as perforating holes or channels, are anatomic arrangements in cortical bones that allow blood vessels to enter the bones from periosteum.They interconnect the Haversian canals (running inside osteons) with each other and the periosteum.

  5. Bone canaliculus - Wikipedia

    en.wikipedia.org/wiki/Bone_canaliculus

    Diameter of canaliculi in human bone is approximately 200 to 900 nm. [1] In bovine tibia diameter of canaliculi was found to vary from 155 to 844 nm (average 426 nm). [ 2 ] In mice humeri it varies from 80 to 710 nm (average 259 nm), while diameter of osteocytic processes varies from 50 to 410 nm (average 104 nm).

  6. Long bone - Wikipedia

    en.wikipedia.org/wiki/Long_bone

    The long bone category includes the femora, tibiae, and fibulae of the legs; the humeri, radii, and ulnae of the arms; metacarpals and metatarsals of the hands and feet, the phalanges of the fingers and toes, and the clavicles or collar bones. The long bones of the human leg comprise nearly half of adult height.

  7. Diaphysis - Wikipedia

    en.wikipedia.org/wiki/Diaphysis

    The diaphysis (pl.: diaphyses) is the main or midsection (shaft) of a long bone. It is made up of cortical bone and usually contains bone marrow and adipose tissue (fat). It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow. In diaphysis, primary ossification occurs.

    Harris presided over the joint session of Congress for the certification. But the encounter between Bruce and Harris started to go viral days after it occurred.

  9. Diploë - Wikipedia

    en.wikipedia.org/wiki/Diploë

    It is a subclass of trabecular bone. [2] In the cranial bones, the layers of compact cortical tissue are familiarly known as the tables of the skull; the outer one is thick and tough; the inner is thin, dense, and brittle, and hence is termed the vitreous table. The intervening cancellous tissue is called the diploë.
