Title: Long Bone Anatomy

Long Bone Anatomy

Shaft Anatomy
  • Diaphysis Shaft made of compact bone with a
    marrow cavity inside
  • Periosteum a protective, vascular, fibrous
    connective tissue membrane around the diaphysis.
  • Sharpeys fibers connect the periosteum to the
    bone

Ends of the Long Bone
  • Epiphysis the ends of the bone, compact on the
    outside, spongy on the inside
  • Articular Cartilage Slippery hyaline cartilage
    that reduces friction at joints.

Epiphyseal Growth Plate
  • A plate of hyaline cartilage that cause the bone
    to grow lengthwise.
  • As you age, the growth plate stops and is
    replaced with bone (the epiphyseal line)

Medullary (marrow) Cavity
  • Infants Red Marrow that make red blood cells
    fill the cavity
  • Adults Adipose tissue (fat) fills the cavity
  • Red marrow is found in the cavities of the
    spongy bone in flat and long bones.

Marrow

Bone Marrow Transplant
  • While you are awake and pain-free (using local
    anesthesia), bone marrow is removed from the top
    of the hip bone (iliac crest). The bone marrow is
    filtered, treated, and transplanted immediately.
    Other times it's frozen and stored for later use.
    The bone marrow is then transfused through a vein
    (IV line). It naturally transports itself back
    into the intended bone cavities, where it grows
    quickly to replace the old bone marrow
