Articulations 8: Joints Articulations Terms articulation synarthroses amphiarthroses diarthroses synovial joint ball and socket joint condyloid joint gliding joint hinge joint Short Answer 1. For the following functional categories, define and give an example: synarthroses, amphiarthroses, diarthroses. For the following structural categories, define and give several examples: fibrous joints, cartilaginous joints, synovial joints. For the following synovial joints, define and give several examples: plane or gliding, hinge, pivot, condyloid, saddle, ball and socket. Be able to draw and label the structures of a knee joint. Know functions. Include: fibrous (joint) capsule, joint cavity, synovial membrane, synovial fluid, articular cartilages, semilunar cartilages (menisci), bursa, fatty pad, patellar ligament, medial collateral ligament, lateral collateral ligament, anterior cruciate ligament, posterior cruciate ligament. pivot joint daddle joint first class lever second class lever third class lever intrinsic or capsular ligament extracapsular ligament intracapsular ligament tendon sheath

Long Answer 1. Be able to draw and explain the following levers. Label the fulcrum or pivot, force or effort and weight or resistance. Give examples from common household items (i.e., scissors). Include: first class lever, second class lever, third class lever. Analyze muscle/bone systems as levers. Show by drawing or word explanation which is the fulcrum, force and weight. Know which type of lever is being used. Include these movements: flexion of the lower arm (biceps contraction), extension of lower arm (triceps contraction), going up on toes, lifting head from a bowed position. 1
