the skeleton system Flashcards

The bones that form the longitudinal axis of the body

The bones of the limbs and girdle

Includes the joints cartilage and ligaments

Support, protection, movement, storage and blood cell formation

Compact bone spongy bone long bones, short bones, flat bones irregular bones

Dense and looks smooth and homogeneous

Composed of small needle like pieces of bone and lots of holes

Longer than they are wide and are mostly compact bone. All bones of the limbs except the patella and the wrist and ankle bones

Thin, flattened and usually curved. Most bones of the skull, the ribs, and the sternum are flat bones

The vertebrate, which make up the spinal column, and the hip bones.

Muscles use bones as levers to bring about body movement

Or shaft makes up most of the bone's length and is composed of compact bone

The diaphysis is covered and protected by a fibrous connective tissue membrane

Hundreds of connective tissue fibers

Ends of long bone

Covers the external surface of the epiphysis. Glassy hyaline cartilage, it provides a smooth, slippery surface that decreases friction at joint surfaces

In adult bone there is A thin line spanning the epiphysis that looks a bit different from the rest of the area.

A flat plate of hyaline cartilage seen in young growing bone. Causes the lengthwise growth of a long bone

In adult cavity of the shaft is primarily a storage of adipose tissue.

In infants this area forms blood cells

Mature bone cells

Osteocytes are found within the matrix in tiny cavities

The lacunae are arranged in concentric circles

Surrounds the lamellae

Complex consisting of central canal and matrix rings

Tiny canals. Radiate outward from the central canals to all lacunae

Diaphsis

They carry nutrients to the bone cells

Bones form using hyaline cartilage structures as their models

Bone forming cells

Bone-destroying cells in bones

Membranes or cartilage

Large, rounded projection may be roughened

Narrow ridge or bone; usually prominent

Very large, blunt, irregularly shaped process ( the only examples are on the femur)

Narrow ridge of bones; less prominent than a crest

Small, rounded projection or process

Sharon, slender, often pointed projection

Any bony prominence

Bony expansion carried on a narrow neck

Smooth, nearly flat articular surface

Rounded articular projection

Armlike bar of bone

Furrow

Narrow, slitlike opening

Round or oval opening through a bone

Indentation at the edge of a structure

Canal-like passageway

Cavity within a bone, filled with air and lined with mucous membrane

Shallow, baseline depression in a bone, often serving as an articular surface

Formed by 2 sets of bone. Facial and cranium

Frontal bone, parietal bone, temporal bone,occipital bone, sphenoid bone and ethmoid bone

Maxillae, palatine bones, zygomatic bones, lacrimal bones, nasal bones, vomer bone, inferior nasal conchae, and mandible

Closely related to the mandible and temporal bones. It is unique in that it is the only bone that does not articulate directly with any other bone. Moveable base for the tongue

Fibrous membranes connecting the cranial bones

Skull, vertebral column, and bony thorax

These are the temporomandibular joints

Maxillae

Ethmoid bone

Frontal joins with the parietals at the coronal suture. Parietals joins one another at the sagittal suture
