Question | Answer |
Humerus | Long bone of the upper arm. Contains a head, which fits in the glenoid cavity on the scapula. |
Maxilla | Two bones fused to form the upper jaw. Carries the upper teeth. |
Mandible | Lower jaw bone. Carries the lower teeth. |
Occipital | Located at the back and base of the skull. |
Foramen Magnum | Large hole in the occipital bone. Allows the brain stem to extend downward as the spinal cord. |
Zygomatic | The cheekbones. Form part of the orbits of the eyes. |
Atlas | Supports the skull and allows us to nod "yes". First cervical vertebra. |
Axis | Allows your head to rotate from side to side as we say "no". Second cervical vertebra. |
True Ribs | Anteriorly the top seven pair of ribs that attach to the sternum by costal cartilage. |
False Ribs | The next five pair of ribs that follow the true ribs, attach indirectly to the sternum or do not attach at all, the floating ribs. |
Floating Ribs | The bottom two pair of false ribs lack sternal attachment. |
Fontanels | Soft fibrous membrane (soft spots) and the pulse can be felt in the soft spots.Infants skulls have not been converted to bone. |
Tibia | Is the shinbone and articulates with the femur at the knee. |
Fibula | The long thin bone that is positioned laterally along side the tibia in the lower leg. |
Patella | The kneecap. Triangular bone that is located within a tendon that passes over the knee. |
Vertebral Column | Also called the backbone, extends from the skull to the pelvis. Consist of 26 bones called vertebrae. |
Bones of the Hands | Carpals, Metacarpals and Phalanges. |
Bones of the Feet | Tarsals, Metatarsals and Phalanges. |
Periosteum | Tough fibrous connective tissue membrane that covers the diaphysis. |
Osteons | The microscopic unit of compact bone. Consists of mature osteocytes arranged in concentric circles around large blood vessels. |
Frontal | Forms the forehead and upper part of the bony structure surrounding the eyes. |
Foramen Magnum | The large hole in the occipital bone. |
Meatus | A tunnel or tubelike passageway. |
Epiphyseal Disc | The growth bone. Longitudinal bone growth. |
Ulna | The second bone of the forearm. The bone on the pinkie side of the forearm. |
Radius | The first bone of the forearm. The bone on the thumb side of the forearm. |
Joints (Articulations) | Is the site where two bones meet. Joints perform two functions: they hold the bones together and they provide flexibility to a rigid skeleton. |
Hematopoiesis | Process of blood cell production. |
Red Bone Marrow | Produces blood cells. |
Long Bones | Longer than they are wide. |
Short Bones | Shaped like cubes and are found primarily in the wrists and ankles. |
Flat Bones | Thin, flat and curved: ribs, breastbone and the skull. |
Irregular Bones | Differently shaped: hip bones, vertebrae, etc. |
Scoliosis | Lateral curvature, usually involving the thoracic vertebrae. |
Kyphosis | Exaggerated thoracic curvature, also known as hunchback. |
Lordosis | Exaggerated lumbar curvature, also know as swayback. |
Acetabulim | Three bones joined together to form a depression. It receives the head of the femur, allowing the thigh to rotate at the hip joint. |
Olecranon Process | Depression of the ulna when the elbow is extended (arm is straight). |
Ischial Tuberosity | Part of the coxal bone you sit on. |
Obturator Foramen | A large hole that is formed as the pubic bone fuses with a part of the ishium. |
Greater Trochanter | Bony process on the femur, provide sites of attachment for many muscles. |
Lesser Trochanter | Bony process on the femur, provide sites of attachment for many muscles. |
Immovable Joints | The sutures of the skull are immovable joints. |
Slightly Movable Joints | Permit limited movement, usually achieved by bones connected by a cartilaginous disc. |
Freely Movable Joints | Synovial Joints. Provide much more flexibility and movement. |
Diaphysis | Long shaft of the bone. |
Epiphysis | Enlarged ends of the long bone. |
Ossification | Formation of bone. When cartilage and connective tissue change into bone. |
Osteoblast | Bone forming cells. |
Osteoclast | Bone destroying cells. |
Ilium | Flared upper part of the bone and can be felt at the hip. |
Ischium | Most inferior part of the coxal bone. |
Pubis | Most anterior part of the coxal bone. |
Spongy Bone | Soft bone. |
