4 major types of joints | Bony (synotosis), fibrous, Cartiloginous, synovial |
Bony joints | 2 separate bones fuse to become one |
Fibrous joints | connect one bone to another with collagenous fibers |
Cartilogious joints | bones held together by cartilage |
Synovial joints | two bones in capsule that contains synovial fluid |
types of fibrous joints | suture; gomphosis, syndemosis |
example of suture (fibrous joint) | frontal and parietal bones |
example of gomphosis (fibrous joint) | teeth and mandible |
example of syndemosis (fibrous joint) | inerosseous membrane between tibia and fibula or ulna and radius |
2 types cartilaginous joints | synchodrosis and symphysis |
synchrodosis joint | composed of hyaline cartilage |
symphysis joint | composed of fibrocartilage; example pubic synthesis and bodies of vertebrae and vertebral discs |
Serrate sutures | wavy line like jigsaw puzzle |
Examples of serrate sutures | coronal, sagital and lamboidal joints |
lap (squamous) | 2 bones hav e overlapping beveled edges |
example of lap (squamous) suture | where temporal bone meets sphenoid and temporal bones |
Plane (butt) sutures | 2 bones have straight non-overlapping edges |
Example of plane (butt) suture | intermaxillary suture in the roof of the mouth |
Label synovial joint |  |
6 types of synovial joints | Plane, hinge, pivot, condylar, saddle, ball and socket |
example of plane joint (synovial joint) | allow movement between 2 flat surfaces; intertarsal or intercarpal joints |
example of hinge joint (synovial joint) | allows for angular movement (elbow, knees, phalanges of fingers |
example of pivot joints (synovial joint) | allow for rotational movement between 2 bones; atlas and axis of neck |
example of condylar joints (Synovial joint) | allow significant movement in 2 planes; convex surface paired with concave; junction between radius and scaphoid and metacarpals and phalnages |
example of saddle joints (synovial joint) | 2 concave surfaces articulate with each other; between tranpezium and 1st metacarpal of thumb |
examples of Ball and socket joints (synovial joint) | consist of spherical head in a round concavity; shoulder and hip joints |
flexion | a movment that DECREASES the joint angle |
Extension | movement that STRAIGHTENS a joint and returns it to zero position |
hyperextension | extension of joint BEYOND ZERO POSITION |
Abduction | body part moves AWAY from the midline of body |
Adduction | body parts moves TOWARD the midline of the body |
elevation | RAISES body part VERTICALLY in FRONTAL plane |
depression | LOWERS a body part VERTICALLY in FRONTAL plane |
Protraction | ANTERIOR movement of body part in TRANSVERSE (horizontal) plane |
Retraction | POSTERIOR movement of body part in transverse plane |
Dosiflexion | elevates toes |
Plantarflexion | movement of foot so toes point downward (pressing a gas peddle) |
tooth held in bone by | peridonatal ligament |
intraosseus membrane | allow radius and ulna to supinate and pronate |
synovial joint is the most ______ joint in the body | movable and most likely to develop painful dysfunction |
prosthesis | artificial joints |
arthritis | painful inflammation of joints |
osteoarthritis | wear and tear arthritis |
rhuematodi arthritis | autoimmune attach on joint tissue |
rheumatologist | specializes in treatment of arthritis and other joint disorders |
