Types of Bone
What are sesamoid bones?
The part of the bone that is a bony outgrowth to which muscles attach.
What is apophysis?
Standing upright, head faces forward, arms at side, palms face forward, thumbs pointed outward, feet flat and toes pointing outward.
What is the standard anatomical position?
The helper muscle that keeps range of motion in line.
What is the stabilizer?
Immovable joints of the skull.
What are sutures?
Also called supernumerary, they are extra bones in the body.
What are accessory bones?
The part of the bone that is the shaft.
What is diaphysis?
Away from the midline of the body.
What is lateral?
The muscle helps stabilize movement so there will be no dislocation.
What is synergist?
An immovable joint.
What is synarthrodial?
These bones are sometimes the result of bone not fusing or differential development. For example an unfused frontal bone.
What are bipartite bones?
The membranous surface that covers the outside of the bone.
What is the periosteal surface?
Nearest articulation with the axial skeleton.
What is proximal?
Connects bone to bone OR bone to cartilage.
What is a ligament?
Rotating to a prone position (like palm facing backwards)
What is pronation?
These bones are solid, dense, and very strong. They are the outer edges of all bone.
What is compact bone? OR What is cortex?
The 30% organic component of bone.
What is collagen?
Divides the body into anterior and posterior halves.
What is coronal?
The primary moving muscle and the opposing mover to that primary.
What are the agonist and antagonist muscles?
What flexing occurs when you point your toes upward?
what is dorsiflexion?
This bone structure lies under articular cartilage and contains marrow. It also contains microscopic vascular canals that nourish said cartilage.
What is a subchondral bone?
The supporting bundles of bony fibers in cancellous bone.
What are trabeculae?
A horizontal cut anywhere there is perpendicular to sagittal and coronal planes.
What is transverse?
Connects muscle to bone.
What are tendons?
Slightly movable joints like the pubis symphysis.
What are cartilaginous joints?
