how many different types of bones are there? name them.
the point of connection between two bones
what are the three types of joint movability
what are three types of bone cells
principle bone-building cells that produce hard calcium compounds and flexible collagen
mature bone cells that help maintain the hard bone tissue by removing and replacing calcium compounds in a bone
bone-destroying cells that break down bone and release calcium and phosphate ions into the blood
Sac filled with synovial fluid that decreases friction between a tendon and a bone.
Shaft of a long bone containing a narrow canal filled with yellow bone marrow.
end of a long bone
fibrous connective tissue between flat bones in the developing cranium.
fibrous connective tissue that connects bone to bone
process of bone formation
Dense fibrous membrane covering the surface of bones except at the joints.
Connective tissue membrane that lines joint cavities and secretes synovial fluid.
Tough, white, cordlike tissue that attaches muscle to bone.
what are the five types of freely movable joints? and give examples of each.
ball-and-socket joint (shoulder)
saddle joint (base of the thumb)
hinge joint (knees)
pivot joint (the vertebrae that lets the head turn)
gliding joint (the joints between the carpals in the wrist)
provides the most freedom of movement of any joint. In this type of joint, the round head of one bone fits into a cup-shaped depression in another bone.
A saddle joint allows the next greatest amount of movement. All movement except rotation is possible with this type of joint.
A hinge joint allows backward and forward movement in only one direction
A pivot joint consists of a cylinder of one bone rotating within a ring formed by another bone. Movement occurs only around a single axis.
A gliding or plane joint allows only a small amount of movement as the flattened or slightly curved surfaces of bones slide or glide over each other in various directions.
