The bodily system that consists of the bones, their associated cartilages, and the joints, and supports and protects the body, produces blood cells, and stores minerals.
the bony skeleton of the head of vertebrates; consists of the eight bones that form the cranium, 14 bones that form the face, and six bones in the middle ear
substances that the body cannot manufacture but that are needed for forming healthy bones and teeth and regulating many vital body processes
A mineral that is essential for bone growth, teeth development, blood coagulation, and many other functions
ground substance; crystalline matrix of bone; very rigid structure ~ gives bone excellent support & protection
abnormal loss of bony tissue resulting in fragile porous bones attributable to a lack of calcium
a fat-soluble vitamin that prevents rickets; promotes growth and health of bones; works with calcium and phosphorus to build bones and teeth
disease caused by deficiency of vitamin D and sunlight associated with impaired metabolism of calcium and phosphorus
membrane surrounding bones; rich in blood vessels and nerve tissue; serves as an attachment for tendons and muscles
process that ensures bone maintenance through simultaneous bone resorption and formation
layer of bone tissue having many small spaces and found just inside the layer of compact bone
red bone marrow
involved in blood cell formation; located in the cavities between the spicules in spongy bone
yellow bone marrow
gradually replaces red bone marrow in adult bones; functions as storage for fat tissue and is inactive in the formation of blood cells
works like a shock absorber; keeps your bones from hurting when they rub against one another
bones that are generally small and cube shaped and contain multiple articulating surfaces; examples are the carpals and tarsals.
thin, flattened, and usually curved, two thin layers of compact sandwiching spongy bone (skull, ribs, sternum)
small, round bones that are embedded in certain tendons; often found in the hands and feet; the largest is the patella
bone that doesn't fit in any other category;
mostly spongy bone with thin compacty outer layer; e.g. vertebrae, facial bones
animals having a bony or cartilaginous skeleton with a segmented spinal column and a large brain enclosed in a skull or cranium
spinal / vertebral column
the group of bones that extends from the base of the skull to the hips and surrounds the spinal cord
the first set of seven vertebrae that form the neck; also known as C1 through C7
the second set of 12 vertebrae; form the outward curve of the spine and are known as T1 through T12
column of nervous tissue from the brainstem through the vertebrae, responsible for nerve conduction to and from the brain and the body
consists of the clavicle and scapula; functions to attach the upper extremity to the axial skeleton
shin bone; the inner and thicker of the two bones of the human leg between the knee and ankle
viscid lubricating fluid secreted by the membrane lining joints and tendon sheaths etc.
joints that move back and forth like the movement of a door hinge; these joints are located at your fingers, toes, elbows, and knees.
most movable joint, ball shaped head of one bone fits in another concave depression; shoulder and hip
permit one bone to slide in two directions; only one pair exists and it is between the thumb and wrist
