Question Answer
Synarthroses joints are how moveable? (syn meaning together)immovable
Synarthroses joints are made up of:interosseous tissue ex. skull, radial/ulnar joint, fibula/tibia
Amphiarthroses joints are how moveable?slightly moveable usually
Amphiarthroses joints are made up of: (amphi- meaning bone and tissue)cartilaginous tissue
Diarthroses joints are how movable? Extremely, permit free movement
Diarthroses joints are made up of:synovial fluid (aka synovial joints)
Types of synarthroses joints (2)suture (skull) and syndesmosis (ligament, cord, aponeurotic membrane) all with interosseous membrane/tissue
Types of amphiarthroses (3)symphysis (pubis), synchondrosis (first rib), gomphosis (gums)
Diarthroses (synovial joints) are connected viasynovial joint capsule, ligaments, tendons, designed primarily for mobility
Synovial joints in body are thehip and shoulder
Synovial joints stabilizing structuremenisci, disks, plates, labrum
1 dfmost stable (hinge joint) elbow
2 dfsemi moveable and stable (ankle, CMC of thumb)
3 dfmost movable (shoulder)
joints are either designed for mobility or stability
spheroid aka ______. how many axis?ball and socket (shoulder and hip) tai-axial
hinged joint is ____ axial and allows for what movementsuni- axial, flexion and extension (elbow)
modified hinge joint is ___ axial and allows for what movementsbi-axial, flexion and extension and slight rotations (knee and ankle)
ellipsoid aka _______. is _____ axial and allows for what momentscondyloid. is bi axial, all motions except rotation and opposition (MCP joint in hand)
trochoid aka ______. is _____ axial and allows for what movementspivot. is uni-axial and allows for rotation and pronation and supination (C1/C2 atlantoaxial joint and proximal radial/ulnar joint)
Reciprocal Reception aka_______. is _____ axial and allows for what movements saddle joint. is bi-axial and allows for all motions except rotation (CMC of thumb)
Plane or gliding joint. is ______ axial and allows for what movementsnon-axial. allows for bones to glide on each other. (intercarpals/intertarsals)
Combined ginglymus & gliding is ____ axial and allows for what movementsuni-axial, allows for flexion and extension and gliding (TMJ joint)
Open Chain (think about using core or not) *freeing the chains, moving those distal segments*distal segment is moving in relation to fixed core (think open door, core doesn't move only arm) ex. elliptical equipment, bicep curl, leg press)
Closed Chain (more functional) distal segment is closed and not moving, proximal part is moveable. (pushup, squat )
Loose packed positionmid range of ROM, most joint play, mobilizaiton/ and traction
Closed packed extremes of motion, joint surfaces in maximal contact, least moveable of joints at extremes of ROM
Isometric (no meters, we use feet)tension without change in length (plank)
isotonicincrease tension with change in length (bicep curl)
to get stronger, you should strengthen eccentric/concentric eccentric. !!!! (need to do more than resist bench press weight)
CA: lateral epicondylitis: have them hold weight in hand and flex the wrist on blue pillow in order to strength the _____ contractioneccentric!!
Agonist =prime mover
antagonist = against prime mover
synergiestalong with prime mover
passive insufficiency when the antagonist is crossing over 2 joints and is not at optimal length preventing full ROM (ex. hamstrings when touching toes or when you can do more hip extension with knee flexed than straight)
active insufficiency (active is more important than passive, agonist more imp. than antagonist)when the agonist is of insufficient length preventing full joint ROM (hip flexion better when knee bent than when straightened)
bony end feellike hitting a wall, orthopedic prob
soft end feelelbow flexion, spongy
firm end feelspongy (shoulder flexion) has some recoil
tractionjoint surfaces pulling apart
approximationjoint surfaces pushed together
concave convexbone slide in same direction as joint surfaces
convex concavebone slide in opposite direction as joint surfaces
