ANTR 350 1st Edition Lecture 6Outline of Last Lecture I. The skullII. Features of the craniumOutline of Current Lecture II. Joint overviewIII. Functional classificationIV. Structural classificationV. Bursa Current Lecture-joint overview-articulation: joint-arthrology: the study of joints-there is an inverse relationship between joint stability and joint mobility-joint stability is determined by-the distance between the bones-the shape of the bone surfaces-the surrounding ligaments, tendons, and muscles-functional classification: based on degree of mobility1. synarthrosis: no mobility (very strong and stable); bones held close to one another, space filled by cartilage or fibrous connective tissue2. amphiarthrosis: limited mobility3. diarthrosis: highly mobileThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.-structural classification1. fibrous joint-bones are held together by fibrous connective tissue-mostly synarthrodial – no movement-cranial sutures: between bones of skull-syndesmoses: tight ligaments hold together bones-gomphoses: between tooth and its socket2. cartilaginous joint-bones are held together by cartilage-range from synarthrodial to amphiarthrodial3. synovial joint: mostly diarthrodial – lots of mobility-bursa: fluid filled synovial sacs-protects structures from excessive friction; found where tendons glide over a bone or between bone and skin-bursitis: inflammation of bursa; causes joint
