PPT-Articulations

The Skeletal System Articulations Articulations Introduction Joints or articulations are connections between bones that may or may not permit movement Cartilage fluid or dense connective tissues is usually involved in holding joints together. washingtonedu Ivan Beschastnikh Computer Science and Engineering University of Washington ivancswashingtonedu David W McDonald The Information School University of Washington dwmcuwashingtonedu ABSTRACT Successful online communities have complex coop (Joints). Articulations. Body movement occurs at joints (articulations) where 2 bones connect. Joint . Structure. Determines direction and distance of movement (range of motion). Joint strength decreases as mobility increases. Chapter 11 Joints. Joints. b) . Fibrous Joints. 1) connections between adjacent bones. 2) . syndesmoses. . to . gomphoses. 3) . ex.suture. . c) . Cartilagenous. Joints. 1) cartilage joins bones. Classify and describe the general structure of a joint. . Classification of Joints. Fibrous – . joined by fibrous tissue; no joint cavity. Mostly immovable. . Cartilaginous- . joined by cartilage; no movement. No movement. . Introduction For simplicity’s sake, this experiment examines the most significant set of articulations in the body. You will also have the opportunity to explore six various types of articulatio Baraniuk. . Chinmay. . Hegde. . . Sriram. . Nagaraj. Go With The Flow.

Joints can be classified by function or . structure. Functional classification . is. . based on amount of movement. Synarthroses. —immovable; common in axial skeleton. Place features.

Effects of aging on the joints. AP1 Chapter 8. 2. I. Naming of joints. Articulation. – A joint, or point of contact between bones. 3 major categories based on function or structure.. For this class we will focus on structure.. 3 types of joints. Fibrous . Joints with differing amounts of connective tissues. Some of these joints have limited movement but most are fixed and have no movement. Articulations!! (the Joints) Section 1: Joint Design and Movement Articulations (_____________________) Where two bones interconnect Bones are relatively inflexible so necessary to allow movement Reflect compromise between need for strength versus need for ). Articulation. Site where two or more bones meet. Functions of joints. Give skeleton mobility. Hold skeleton together. Two classifications. Functional. Structural. .
