Skeletal/Muscular/Integumentary
| Question | Answer |
|---|---|
| What are the 5 functions of muscles? | 1. Thermogensis -Heat production 2. Motion 3. Posture 4. Controls organ volume Protection of internal organs |
| biceps brachii | anterior upper arm |
| triceps brachii | posterior upper arm |
| Trapezius | posterior of neck |
| Deltoid | covers the shoulder |
| Diaphragm | internal muscle that seperates the thoracic and abdominal cavities. Attach to the back of the rib cage |
| pectoralis major | chest |
| latissimus dorsi | superficial muscle of the thoracic and lumbar region of the back |
| rectus abdominis | runs vertically along the abdomen |
| Gastrocnemius | posterior lower leg |
| Hamstring muscle group | Posterior aspect of the thigh |
| Quadriceps muscle group | anterior aspect of the thigh |
| gluetus maximus | buttocks region |
| What are the three types of muscles? | cardiac, smooth, skeletal |
| Tendonitis | inflammation of a tendon |
| strain | A condition resulting from damaging a muscle or tendon |
| Degrees of strains | 1rd degree -muscle is stretched causing micro tears in the muscle fibers 2nd degree- muscle or tendon partially torn 3rd degree- muscle is completely ruptured |
| muscle spasm | involuntary muscle contraction |
| Musclular Dystrophy | Group of inherited muscle-destroying diseases; Muscles enlarge due to fat and connective tissue deposits; Muscle fibers atrophy |
| What are the functions of the skin? | 1- Protection 2- Synthesis of vitamin D 3-Reception of stimuli 4-Temperature Regulation 5-Protection against UV |
| What are the 3 layers of the skin? | epidermis, dermis, subcutaneous |
| Epidermis | outermost layer of skin |
| Dermis | middle layer of skin |
| Subcutaneous | The 3rd layer of skin |
| Nails | Composed of dead skin cells, Helps grabs and manipulates small objects |
| sweat | Produced by sudorfierous glands in order to cool down body |
| oil (sebacous) gland | Hair follicles, keeps hair and skin from drying out |
| hair | Protection, guards scalp, eyebrows and eyelashes protect eyes |
| Acne | inflammatory disease of the skin involving the sebaceous glands and hair follicles |
| jock itch | A group of fungal infections (ring worm, athletes foot) |
| skin cancer | uncontrolled cell growth of the skin |
| Types of Skin cancers | basal cell carcinoma, squamous cell carcinoma, malignant melanoma |
| basal cell carcinoma | Sun exposed to face, ears, neck, scalp, shoulders and back |
| squamous cell carcinoma | chronic overexposure to the sun |
| Melonoma | found on the trunk or the head and neck |
| Assess for skin lesions (ABCDE) | A: Asymmetry B: Border C: Color D: Diameter E Evolution/Elevation |
| Cranium | the portion of the skull that encloses the brain |
| Frontal | forms the forehead |
| Parietal | forms the sides and roof of the cranial cavity |

| cervical vertebrae | vertebrae of the neck |
| Thoracic Vertebrae (T1-T12) | vertebrae to which ribs attach |
| Lumbar Vertebrae (L1-L5) | large, weight bearing vertebrae of the lower back |
| Sacral Vertebrae (S1-S5) | Fused vertebrae which articulate with the pelvic bones |
| coccygeal vertebrae (coccyx) (4) | the vertebrae of the tailbone |
| Bones of the thoracic cavity | enclose and protect the heart and lungs |
| Sternum | breastbone |
| Ribs | 12 pairs attached to the thoracic vertebrae |
| Humerus | upper arm bone |
| Radius | thumb side of lower arm |
| Ulna | medial to radius; lower arm |
| Carpals | wrist bones |
| Metacarpals | hand bones |
| Phalanges | fingers |
| Illium | hip bone |
| Ischium | butt bone |
| Pubis | the bone of the pubic region |
| Femur | thigh bone |
| Patella | kneecap |
| Tibia | shin bone |
| Fibula | Smaller lower leg bone |
| Tarsals | bones of the hind foot |
| Metatarsals | bones of the forefoot |
| Phalanges | toes |
| Articulation | any location where 2 bones meet |
| Functions of the skeletal system | support, protection, movement, storage, blood cell formation |
| scoliosis | abnormal lateral curvature of the spine |
| Osteoarthritis | inflammation of the bone and joint |
| sprain | stretching or tearing of ligaments |
