PPT-Joints ( Articulations

Articulation Site where two or more bones meet Functions of joints Give skeleton mobility Hold skeleton together Two classifications Functional Structural Functional Classification of Joints . 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.. (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. Joints in the . H. uman . B. ody. What are articulations?. Articulations are joints. Places where two or more bones meet. There are 3 major categories:. Fibrous joints, aka . synarthrotic. joints. Cartilaginous joints, aka . The “Moving” Part of Anatomy!. Introduction. Many major sports, activities and hobbies require us to be able to move around. These movements define us as human because we have a unique ability to move in the animal kingdom. 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. . JOINTS. ARTICULATIONS. Classifications of Joints. Joints can be classified by function or . structure. Functional classification . is. . based on amount of movement. Synarthroses. —immovable; common in axial skeleton. AP1 Chapter 8. 1. Chapter 8 Outline. Naming joints. Classes of joints. Types of movement. Range of motion. Description of selected joints. Effects of aging on the joints. AP1 Chapter 8. 2. I. Naming of joints. Bone articulations (joints). A. Defined – . place where two bones come together. ; usually considered movable but some are very limited in movement and others are completely or almost completely immovable. 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. 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 . 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 Synovial Joints. What are synovial joints?. Freely movable joints. Contain a cavity filled with thick, slippery fluid (Synovial fluid). Found mostly in articulations of the . appendicular. skeleton. B. Functions – dependent on need for strength and mobility. 1. J. oints . in skull are very strong & immovable. 2. . Joints . in appendages are more flexible but not very strong (surrounding muscles provide the strength).
