Plane terminology: sagittal: a plane that divides the body into left and right parts, coronal: a plane that divides the body into dorsal and ventral parts, transverse: a plane that divides the body into superior and inferior parts. Cartilaginous joints: cartilaginous joint (synchondrosis): bones united by cartilage, little movement, symphysis: cartilage between bones covered with hyaline cartilage. Other joints: fibrous joint (syndesmosis): tight and inflexible, bones united by bands of dense fibrous tissue, cranial sutures: fibrous joints of skull, synostosis: two bones fuse together. Bone types: compact or cortical bone, solid/dense, in walls of bone shaft, subchondral bone: bone that"s under cartilage, cancellous, trabecular, spongy bone, lightweight and honeycombed. Bone remodeling: wolff"s law: bone deposited where its needed and removed where its not, remodeling of bone continues throughout life. Osteological variation: ontogenetic: growth, age diff, sexual dimorphism: sex diff, geographic: regional diff, individual: diff between individuals, phylogenetic: species diff.
