The Skeletal System Flashcards
Slightly moveable joint
Amphiarthroses
The cup like cavity on the lateral surface of the hip bone that receives the head of femur bone
Acetabulum
Bones of the limbs and limb girdles that are attached to the axial skeleton
Appendicular skeleton
Membrane that covers the ends of bones forming a joint
Articular cartilage
The skull, vertebrae and ribs and sternum
Axial Skeleton
A small sac filled with fluid and located at friction points, especially joints.
Bursa
Tiny canals in bones that radiate outward from the central canals to all lacunae.
Canaliculi
Elastic end of bone
Cartilage
A mature cartilage cell.
Chondrocytes
The bone material that makes up the diaphysis or shaft section of the bone
Compact bone
The shaft section of a long bone.
Diaphysis
A freely movable joint.
Diathroses
Fetal and newborn bone growth and formation.
Endochondrial ossification
Membrane lining a bone cavity.
Endosteum
The end of a long bone.
Epiphyses
The growth plate at the end of a long bone.
Epiphyseal plate
Bones that are flat - sternum.
Flat bones
Openings in newborns skill (soft spot).
Fontanels
Formation of blood cells.
Hematopoiesis
A section of the coxal bone or hip bone.
Ilium
Space between ribs.
Intercostal space
Bones that are not flat, long or short
Irregular bones
The sit down bone (part of the coxal bone).
Ischium
Holes in the osteon (bone).
Lacuna
Outer layer of osteon.
Lamella
Fibers that join bone to bone.
Ligaments
Bones that are long in shape.
Long bones
The center bone of the sternum.
Manubrium
In adults, the cavity of the shaft if primarily a storafe area for fat tissue called yellow marrow or medullary cavity. In infants red marrow is found in this cavity
Medullary cavity
Building up of cells.
Osteoblast
Breaking down of cells.
Osteoclast
Location where cells are built or broken down.
Osteocyte
Structural unit of compact bone.
Osteon
A flat triangular bone located in the combined tendon of the extensors of the leg and covering the front surface of the knee joint. Also called kneecap .
Patella
Shoulder girdle
Pectorial Girdle
Frame of the pelvis.
Pelvic Girdle
Outer membrane on the shaft of the long bone.
Periosteum
Lower ridge of Coxal bone in the pelvis.
Pubis
Any of several small round bones formed in a tendon where it passes over a joint. Example: patella
Sesamoid bone
The bony framework of the head, enclosing the brain and supporting the face; the skeleton of the head. Also known as: cranium.
Skull
Carpals, phalanges, etc
Short bones
Located in the proximal epiphysis of long bone, where bone marrow is formed.
Spongy bone
An immovable joint.
Synarthroses
Membrane that lines a fibrous capsule of a synovial joint.
Synovial membrane
Chest
Thorax
