| Question | Answer |
|---|---|
| Name the 5 Skeletal system functions | 1. Structural support to the body 2. Protection of the organs 3. Movement 4. Stores calcium 5. Forms blood cells in the red bone marrow |
| Name the 5 types of bones | 1. Long 2. Short 3. Flat 4. Irregular 5. Sesamoid |
| What is the functional unit of compact bone? | Osteon |
| What does an osteon look like? | It has layers of rings called lamellae |
| What is the shaft of a long bone called? | Diaphysis |
| What is the hollow center of the bone? | Medullary canal |
| What is the medullary (“middle”) canal filled with? | Yellow marrow (adipose tissue) |
| What is the function of yellow marrow? | Function is to store fat |
| What is the end of the long bone called? | Proximal and distal epiphysis (where spongey bone is) |
| What is the thin layer that covers each epiphysis, provides a cushion? | Articular cartilage |
| What tissue surrounds the whole bone, and what is its function? | Periosteum: serves as the attachment site for tendons and ligaments |
| What is the thin membrane that lines the medullary cavity? | Endosteum |
| What type of bone is a thin layer of compact bone surrounding spongey (cancellous) bone? | Flat bone |
| What type of bone occurs within a tendon, such as the patella (kneecap)? | Sesamoid bones |
| What are the two types of bone tissue? | Spongey (aka cancellous) compact |
| Where is spongey bone found? | In the epiphyses of bones |
| What does spongey bone contain? | Red bone marrow |
| What is the medical term for a mature bone cells? | Osteocyte |
| What is the medical term for a cartilage cell? | chondrocyte |
| What skeletal tissue lacks blood vessels? | Cartilage |
| What is the name of cells that form new bone? | Osteoblasts |
| What is the name of cells that reabsorb bone? | Osteoclasts |
| What is the term for cartilage between epiphyses and diaphysis that remains until skeletal maturity? | Epiphyseal plate |
| What is the medical term for the process by which cartilage is gradually replaced by bone? | Endochondral ossification |
| What are the 2 divisions of the skeleton? | 1. Axial 2. Appendicular |
| What are the bones in the axial skeleton? | 1. Skull 2. Vertebral column 3. Thorax (rib cage) |
| What are the bones of the appendicular skeleton? | 1. Upper extremities 2. Shoulder (pectoral) girdle 3. Lower extremities 4. Hip (pelvic) girdle |
| What are the 4 normal curves of the vertebral column? | 1. Cervical 2. Thoracic 3 Lumbar 4. Sarcal |
| Name 3 abnormal spinal curvatures? | Lordosis (swayback) Kyphosis (hunchback) Scoliosis (side-to-side curve) |
| What bones are part of the thorax? | 12 pairs of ribs Sternum (breastbone) 12 Thoracic vertebrae (those that have ribs) |
| What are 3 types of ribs? | True ribs (the first 7 pairs) False ribs (the other 5 pairs) Floating ribs (the last two pairs of false ribs) |
| what is the name of the shoulder blade? | Scapula |
| What is the name of the collar bone? | Clavicle |
| What is the name of the bone in the arm? | Humerus |
| What is the name of the smaller bone of the forearm? | Radius |
| What is the name of the larger bone of the forearm? | Ulna |

| What is the name of the bone of the thigh? | Femur |
| What is the name of the larger bone of the leg? | Tibia |
| What is the name of the heel bone? | Calcaneus |
| What are 4 differences between a male and female skeleton? | Size (females are smaller) Shape (females are broader) Size of pelvic inlet (hole where baby passes through; females are wider) Pubic angle (females are wider |
| What is different about the hyoid bone? | It does not connect to any other bone. It is above the adam's apple, and anchors the tongue |
| What are 3 types of movement by which joints are classified ? | Synarthrosis ( no movement) Amphiarthrosis (slight movement) Diarthrosis (freely moveable) |
| Describe a synarthrosis joint and give an example | 1. Connective tissues between the bones 2. Skull sutures |
| Describe an amphiarthrosis joint and give an example | Cartilage between the bones Symphysis pubis (joints pelvic bones) |
| Describe a diarthrosis joint and give an example | Has a joint capsule with fluid inside and ligaments outside Shoulder, knee, hip, fingers, elbow |
| What lines joint capsules and secretes a lubricating fluid? | Synovial membrane |
| What are the 6 categories of freely moveable joints? | 1. Ball and socket 2. Hinge 3. Pivot 4. Saddle 5. Gliding 6. Condyloid |
| What are examples of ball and socket joints | Hip and shoulder |
