Document Summary
Produce red blood cells from bone marrow (hemopoietic tissue blood-cell forming tissue) Acts as a storage medium and buffer system for calcium (homeostasis) Classification: classified according to the type of bone tissue (compact or spongy) Classified by the morphology of the bone (short hands, irregular vertebrae, long tibia, flat skull) Cranial cavity: cavity created by the skull bones, where the brain sits. Sutures: joints where skull bones articulate (synarthrodial articulation) Diarthrodial: joint that permits lots of movement. Foramen: naturally occurring holes within a bone. Divided into cranium bones and facial bones. Parietal (2): two bones that cover the parietal region of the brain connected by the sagital suture. Temporal (2): two bones that cover the temporal region of the brain. Contains external ear, mastoid process (larger bump), styloid process (pen-like. Mastoid and styloid processes serve as places where muscles attach. Frontal: bone that covers the frontal region of the brain, separated by parietal bone by frontal suture.
