Musculoskeletal 68Q
Therapeutics Intro
| Question | Answer |
|---|---|
| 3 muscle tissue types | Skeletal, smooth, and cardiac |
| Dark myofilament bands | Myosin |
| Light myofilament bands | Actin |
| how many bones are in the adult human body? | 206 |
| What is the bone process at birth? | Ossification, cartilage changing to hardened bones. |
| Bones found in the arms and legs | Long |
| Bones found in the wrists and ankles | Short |
| Bones found in the skull and shoulder blades | Flat |
| Bones found in the face and vertebra | Irregular |
| Bone Shaft | Diaphysis |
| Enlarged end of a long bone | Epiphysis |
| Disc of cartilage separating the epiphysis from the diaphysis | Epiphysis Plate |
| Hollow cavity in the diaphysis of a long bone where yellow marrow is stored | Medullary Cavity |
| Tissue that produces blood cells | Red bone marrow |
| Membrane covering the outside of all bones | Periosteum |
| Spongy bone found in the ephiphysis and contains bone cells | Cancellous Bone |
| Bone builders, form a bone matrix that becomes enclosed as an osterocyte | Osteoblasts |
| Mature bone cells within the compact bone matrix. Maintain bone as living tissue and sustain daily bone. | Osteocytes |
| Large multinucleate cells that break down bone and play a role in mineral homeostasis | Osteoclasts |
| White fibrous connective tissue, cartilage, and bone | Collagen |
| Consists of Calcium and phosphate, weight-bearing strength | Hydroxyapatite |
| Necessary for collagen synthesis by the osteoblasts | Vitamin C |
| Necessary for the normal absorption of calcium from the intestines | Vitamin D |
| Junction between 2 or more bones where bones are connected together, aka articulations | Joint |
| Connective membrane that lines joints and produces a clear lubricating liquid | Synovium |
| A closed sac containing synovial fluid | Bursa |
| A group of collagen fibers connecting bone to bone | Ligament |
| Connect muscles to bone | Tendons |
| Consists of a single neuron and all muscle fibers that the neuron's branches innervate | Motor Unit |
| Constant tension produced by muscles for long periods of time | Muscle tone |
| Functions in movement, posture, and heat production | Skeletal Muscle |
| When a chemical energy stored in cells breaks down. | Heat production |
| The thick filament responsible for contraction | Myosin |
| The filament responsible for contraction and relaxation | Actin |
| What slides inward along myosin, shortening the muscle fiber as contraction occurs? | Actin filaments |
| Functions in peristalsis and blood pressure regulation | Smooth Muscle |
| Smooth muscle contraction results in the movement of materials inside the body, such as the propulsion of food and liquid through the digestive tract. | Peristalsis |
| Contracts rhythically and acts as a pump to move blood through the cardiovascular system | Cardiac muscle |
| Functions are hematopoiesis, protection of vital organs, and storage of calcium and phosphate | Skeletal system |
| Production of red and white blood cells within the red bone marrow found in spongy bone | Hematopoiesis |
