Laboratory Manual for Anatomy and Physiology: Overview of the skeleton - lab Flashcards

Constructed of two of the most supportive tissues found in the human body: cartilage and bone.

Hyaline

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

Canal-like passageway

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

Slit-like furrow

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

The shaft

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

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

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.
