Overview of the skeleton - lab
Constructed of two of the most supportive tissues found in the human body: cartilage and bone.
In embryos, the skeleton is composed mainly of______ cartilage
Site for blood cell formation
Red marrow cavities
Bones that form the body's longitudinal axis
Bones of the girdles and limbs
Bumps, holes, and ridges
Large rounded projection; may be roughened
Narrow ridge of bone, usually prominent
Very large, blunt, irregularly shaped process. Only on the femur.
Narrow ridge of bone; less prominent than a crest
Small rounded projection or process
Raised area on or above a condyle
Sharp, slender, often pointed projection
Arm-like bar of bone
Boney expansion carried on a narrow neck
Smooth, nearly flat articular surface
Rounded articular projection
Cavity within a bone, filled with air and lined with mucous membrane
Shallow, basin-like depression in a bone, often serving as an articular surface
Narrow slit-like opening
Round or oval opening through a bone
Dense and looks smooth and homogenous. Riddled with passageways carrying blood vessels and nerves that provide the living bone cells with needed substances and a way to eliminate wastes.
Composed of small trabeculae of bone and lots of open space
Longer than they are wide, made mostly of compact bone. Example :the femur
Typically cube shaped, contain more spongy bone than compact bone. Example: the tarsals and carpels
Generally thin, with a layer of spongy bone sandwiched between two wafer like layers of compact bone. Example: Bones of the skull
Fibrous membrane that covers the bone surface. Many fibers of the _____ (Sharpey's fibers) penetrate into the bone.
The end of the long bone, composed of a thin layer of compact bone enclosing spongy bone
Covers the epithelial surface in place of the curiosity periosteum . Composed of glassy hyaline cartilage, provides a smooth surface to prevent friction at joint surfaces.
A thin layer of hyaline cartilage that provides for growth in bone length. When bone growth ends, these areas are replaced with bone and called epiphyseal lines.
Adipose tissue inside the medullary cavity. In babies the red marrow fills this central cavity.
Lines the medullary cavity
Composes spongy bone
Central Haversian canal
Runs parallel to the long axis of the bone and carries blood vessels and nerves through the bony matrix
Chambers where osteocytes are found in living bone
Arranged in concentric circles around the central canal
Osteon or Haversian system
A central canal and all the lamellae surrounding it
Tiny canals running from a central canal to the lacunae of the first lamella and then from lamella to lamella.
These canals run into the compact bone and marrow cavities from the periosteum, at right angles to the bone shaft.
