AAO Exam 1 Objectives Questions with 100% Correct Answers | Verified | Updated Describe how the body is divided into segments and how that relates to the concept of arthrokinematic motion. - answerBody is divided into segments according to bones (e.g. head, neck, trunk, thorax, abdomen, UE, LE) Arthrokinematic motion: the relationship of joint surface movement (e.g. spin, glide, and roll) Describe and give examples (both inside and outside the body) of both linear and angular motion. - answerLinear motion: sprinter running in a straight line and the diaphragm moving downwards during inhalation Angular motion: LAQ Define osteokinematics as it relates to joint motion and differentiate the terms used to describe joint motion throughout the body (e.g., flexion, extension). - answerOsteokinematics is the relationship of movement of bones around a joint axis e.g. humerus moving on scapula Differentiate the axial and appendicular skeletons. - answerAxial: cranium, face, vertebral column, and thorax Appendicular: UE and LE Recognize the different types of bones found in the body - answerLong bones: clavicle, humerus, radius, ulna, metacarpals, phalanges, femur, fibula, fibula, metatarsals and phalanges Short bones: carpals and tarsals Flat bones: scapula, cranial bones (frontal, parietal, occipital, temporal), ribs, sternum Irregular bones: innominate, vertebrae, sacrum, coccyx, mandible and facial bones Sesamoid: Patella define broad categories of bone markings (depression and openings, projections or processes). - answerDEPRESSION/OPENINGS 1. FORAMEN: hole thru blood vessels, nerves and ligaments pass 2. FOSSA: hollow or depression 3.GROOVE: ditchlike groove containing a tendon or blood vessel 4.MEATUS: canal or tubelike opening in a bone 5.SINUS:air-filled cavity within a bone PROJECTIONS/PROCESSES (FIT INTO JOINTS) 1. CONDYLE: rounded knuckle like projection 2. EMINENCE: projecting, prominent part of bone 3.FACET: flat or shallow articular surface 4.HEAD: rounded articular projection beyond a narrow, necklace portion of bone PROJECTIONS/PROCESSES (ATTACH TO TENDONS, LIGAMENTS, CONNECTIVE TISSUES) 1. CREST: sharp ridge or border 2. EPICONDYLE: prominence above or on a condyle 3.LINE: less prominent ridge 4.SPINE: long, thin projection 5.TUBERCLE: small rounded projection 6.TIBEROSITY: large rounded projection 7.TROCHANTER: very large prominence for muscle attachment Osteoporosis - answera condition characterized by loss of normal bone density. More severe than osteopenia Osteomyelitis - answeran infection of the bone usually caused by bacteria. Open fractures cause a greater risk of developing this than closed fxs Slipped capital femoral ephysis - answeroccurs when the head of the femur becomes displaced due to a separation at the growth plate Legg-Calve-Perthes disease - answerHappens when blood supply is interrupted to the femoral head, causing necrosis of the bone at the pressure epiphysis in growing children Identify joint anatomy and the function of the articular system. - answerfunction of articular system is to allow motion of the musculoskeletal system Define and give examples of the different types of joints found in the body. - answerSynarthrosis: suture joints of th
