| Question | Answer |
|---|---|
| The part of the skeleton composed of the limbs and their attachments | Appendicular Skeleton |
| Another word for joint, the structure created when bones connect to each other. | Articulation |
| The axis of the body, consists of the head, the vertebral column, the ribs, sternum and provides the body with form and protection | Axial Skeleton |
| The hard portion of bone that protects spongy bone and provides the firm framework of the bone & the body. | Compact (dense) bone |
| The bony support structure found inside the human body, it accommodates growth. | Endoskeleton |
| A thin membrane of connective tissue that lines the marrow cavity of a bone. | Endosteum |
| The thin membrane of connective tissue that covers bones except at articulations | Periosteum |
| The quality of bones that allow them to deform slightly & vibrate when electric currents pass through them & to produce minute electric current when deformed or compressed. | Piezoelectric |
| Round bones that often are embedded in tendons & joint capsules. | Sesamoid Bones |
| The lighter-weight portion of bone, which is made up of trabeculae | Spongy (cancellous) bone |
| An irregular meshing of small, bony plates that makes up spongy bone, it's spaces are filled with red marrow. | Trabeculae |
| What makes up the skeletal system? | Bones, joints, connective tissues |
| What are the seven major roles of bones? | 1. Supports soft tissues 2. Provides attachment points for muscles & ligaments 3.Protects internal organs 4.Serves as levers to provide mvmt. 5.Stores calcium & other minerals to release as needed. 6.Stores lipids for energy 7. Produces blood cells. |
| How many bones are in the human body? | 206 |
| What is the connective tissue structure that covers bones and provides vessels for nutrition, bone cells for growth, & attachments for tendons & ligaments? | Periosteum |
| The process of building bone by depositing calcium salts into the tissue. | Ossification |
| Bone building Cells that develop bone tissue from the cartilage model. | Osteoblasts |
| What are two examples of long bones? | Femur & Ulna |
| What are two examples of short bones? | Carpals & Tarsals |
| What are two examples of irregular bones? | Vertebrae & Scapula |
| What is an example of a sesamoid bone? | Patella |
| A tunnel or tube in bone. | Canal |
| A groove or slit between two bones | Fissure |
| An opening or hole in a bone | Foramen |
| A shallow depression in the surface or at the end of a bone. | Fossa |
| A depression in the bone that holds a blood vessel | Groove |
| A tunnel or canal in a bone | Meatus |
| An indentation or large groove | Notch |
| An air cavity within a bone | Sinus |
| A rounded projection at the end of a bone to form a joint | Condyle |
| A rounded projection atop the neck of a bone | Neck |
| A smooth, flat surface | Facet |
| Any prominent bony growth that projects | Process |
| A pulley-shaped structure | Trochlea |
| A ridge on a bone | Crest |
| A projection on a condyle | Epicondyle |
| A ridge that is smaller than a crest | Line |
| A sharp, bony, or slender projection. | Spinous Process |
| One of two large boney processes found only on the femur | Trochanter |
| A small rounded process. | Tubercle |
| A large rounded protuberance | Tuberosity |
| The soft spots of the skull on an infant | Fontanelles |
| Lateral deviation of the spine | Scoliosis |
| A flexion deformity of the spine | Kyphosis |
| An extension deformity of the spine | Lordosis |
| Path. Condt. that occurs when the vertebral arches in a growing fetus do not fuse into the spinous processes. | Spina Bifida |
| Path. Cond. that is a congenital deformity involving a gap in the roof of the mouth from behind the teeth to the back of the mouth. | Cleft Palate |
| A disorder of the bone in which calcium & other minerals are lacking & bone protein is diminished which leaves the bones soft & fragile. Found mostly in postmenopausal women | Osteoporosis |
| Path. Cond which occurs when the bones undergo normal periods of calcium loss followed by periods of excessive new cell growth. Bones become hardened & deformed. | Paget's Disease |
| Path. Cond. which is an inflammation in the bone, bone marrow, or periosteum caused by pus-producing bacteria. | Osteomylelitis |
| Path. Cond which is a childhood disease characterized by numerous bone deformities, is caused by nutritional deficiencies especially with the lack of Vitamin D | Rickets |
| Scurvy is caused by what type of vitamin deficiency? | Vitamin C |
