Some Surface Features of Bones • Processes • Lines • Foramina • Sinuses • Fossa • Sutures
Bone Process • Area where the bone has extra tissue • Projections • Can help form joints • Can provide attachment sites for muscles and ligaments
Bone line • Groove in the bone from other developmental processes • A narrow, low ridge
Bone Foramina • Holes in the bones through which nerves and blood vessels pass • Ligaments may also pass through
Bone sinuses • Empty spaces in the bones that make the skull lighter • Cavity within a bone
Bone fossa • A relatively deep pit or depression
Bone sutures • An interlocking line of union between bones
Muscle features (skeletal) • Striations • Tendons • Origin • Insertion
Muscle striations • Skeletal & cardiac muscle only • The striations seen in skeletal muscle fibers are the result of the alignment of hundreds of myofibrils (long protein strands) within each muscle fiber.
Tendons • A tough band of fibrous connective tissue that usually connects muscle to bone.
Origin • Where the muscle attaches to the bone
Insertion • Where the muscle meets a tendon
