hard protein substance formed when calcium and other minerals mix with osteoblasts and fibers to provide strength to tissues.
mature bone cells made of organic and inorganic material, providing hardness to bone; maintains bone matrix.
epiphyseal plate (growth plate)
area at each end of a long bone responsible for bone growth; bone tissue replaces cartilage tissue, and the bone lengthens.
organic material made of connective tissue and blood vessels that fills the cavities of bones; two types are red marrow, responsible for the manufacture of red and white blood cells, and yellow marrow, composed of fat cells and responsible for white blood cell production
translucent cartilage that covers the ends of bones; also found in locations such as the nasal septum and costal area
outer covering of bone that provides support of blood vessels that nourish the bone and provides attachment of muscles, tendons and ligaments
bones having no distinct shape that make up the spinal column, sphenoid, and ethmoid of the skull, sacrum, coccyx, and the mandible
bones in the central section of the body; skeleton of head, vertebrae, and bony thorax
bones that extends from the top of the eye orbits to the top of the head, forming the forehead
bone that forms the back part of the cranial floor and covers the back part of the brain
facial bones behind the hard palate that help to form the walls of the nasal cavity and the floor of the eye orbits
five vertebrae after the lumbar vertebrae the fuse into one, S1-S5, located between the hipbones
flexible, curved, segmented structure composed of vertebrae that are stacked on one another
bones in the upper and lower limbs and the girdles that attach these to the axial skeleton
place where the ridge of the scapula and the clavicle join, the point of the shoulder
skeletal structure that supports body weight and stretches from the heel bone to the phalanges (toes) formed by tarsals and metatarsals
skeletal structure that supports body weight and extends from one side of the foot to the other side; formed by tarsals and metatarsals
thin layer of cartilage that covers the surface of bones at the point where they come together
combination of flexion, abduction, extension, and adduction; circular motion by a joint
bending motion that brings two close bones together decreasing the angle between articulating bones
imaging technique using x-rays or gamma rays to make a film record (radiograph, x-ray) of internal structures based on changes in tissue density, especially the skeletal system's soft tissue
rheumatoid factor test
test to detect the presence of rheumatoid factor (RF) in the blood; a test for rheumatoid arthritis
cone fractured and bent on one side, but not on the other. children are prone to this type of break because their bones have no completely ossified
bone disease of adults characterized by a deficiency of calcium and vitamin D and the softening of bones
condition caused by more bone cells being destroyed than made; decrease in bone density leaves the bones porous and prone to fracture
slow, progressive disease of bone tissue with excessive and abnormal resorption and formation of bone.
inflammation of one or more joints; usually accompanied by pain, swelling, redness, and stiffness
carpal tunnel syndrome
compression of the median nerve in the wrist causing pain and loss of movement
gouty arthritis (gout)
condition with swelling of joints resulting from uric acid not being metabolized.
condition resulting from cartilage on the end of bones softening and the bones rubbing against each other; deterioration of the joints
condition in which the spinal column in the lumbar and sacral areas does not close completely at birth
