background image Lecture Exam 3 Review Chapter 9: Joints 1. Functional Classification of Joints: A. Syanthrosis- immovable (suture, gomphosis, synchondrosis, synostosis) i. suture: bones interlocked, are bound by dense fibrous CT (skull) ii. gomphosis: fibrous connection (periodontal ligament) (binds teeth  into sockets) iii. synchondrosis: rigid cartilaginous bridge between two bones, 
epiphyseal cartilage of long bones (between vertebral sternal (true) 
ribs and sternum)
iv. synostosis: fused bones, immovable, metopic suture of skull 
(epiphyseal plate)
B. Amphiarthrosis- slightly movable (syndesmosos, symphysis) i. syndesmosis: distal joint between tibia and fibula  ii symphysis: separated by fibrocartilage 9pubic symphysis) C. Diarthrosis- highly moveable, synovial joints (knee) I. planes of movement:  Monaxial- movement in one plane, elbow and  ankle Biaxial- movement in two planes, ribs and wrist Triaxial- movement in three planes, shoulder and  hip 2. Structural Classification of Joints: A. Bony B Synovial C. Fibrous D. Cartilaginous 3. Synovial Joints:  A. function: lubrication, nutrient distribution, and shock absorption B. moveable joints at ends of long bones C. within articular capsules, lined with the synovial membrane which  produces synovial fluid D. Synovial Fluid- contains slippery proteoglycans secreted by fibroblasts
background image 4. Joint Movements: A. Dynamic movements- linear (gliding), angular, and rotation i. planes or axes of dynamic motion: monaxial (one plane), biaxial (two 
planes), triaxial (three planes)
B. Movement at synovial joints- gliding: two surfaces slide past each other 
(carpal and tarsal bones)
C. Angular movement i. flexion: anterior- posterior plane, decreases the angle between  articulating bones ii. extension: anterior-posterior plane, increases the angle between  articulating bones iii. hyperextension: extension past the anatomical position iv. abduction: frontal plane, movement away from the midline v. adduction: frontal plane, movement towards the midline vi. circumduction: moving your arm in a loop D. Rotation- direction of rotation from anatomical position i. left or right rotation: rotation of the head ii. medial rotation or inward rotation iii. lateral rotation or outward rotation iv. pronation: turns the wrist and hand from facing front to palm back v. supination: palm is turned anteriorly, in anatomical position E. Special movements i. inversion: twisting movement of the foot that turns the sole inward ii. eversion: twisting movement of the foot that turns the sole outward  iii. dorsiflexion: flexion at the ankle joint and elevation of the sole , as 
when you dig in your heel
iv. planter flexion: extends ankle joint and elevate the heel, when you  stand on tip toes v. opposition: movement of thumb toward the surface of the palm or 
pads of other fingers, enable you to grab or hold objects between your 
thumb and palm
background image vi. reposition: movement of the thumb that returns the thumb and 
fingers from opposition
vii. protraction: in the horizontal plane, pushing forward, pushing jaw 
forward
viii. retraction: moving anteriorly, pulling back, pulling jaw back  ix. elevation: when closing your mouth x. depression: when opening mouth  5. Axial movement:  A. nonaxial B. monoaxial: one plane C. biaxial: two planes D. triaxial: three planes 6. Structures of Joints A. Shoulder Joint- also called the glenohumeral joint, allows more motion than
other joints, is the least stable, suppoted by skeletal muscles, tendons and 
ligament
i. glenoid labrum: socket of the shoulder joint, fibrocartilage lining, 
extends past the bone, deepens the socket of glenoid cavity
ii. acromion (clavicle) and coracoid process( scapula): help stabilize the
joint, superior to the humerus, 
iii. shoulder ligaments:  a. glenohumeral  b. coracohumeral c. coracoacromial d. coracoclavicular e. acromioclavicular iv. shoulder muscles- SITS a. supraspinatus b. infraspinatus c. teres minor d. subscapularis
background image v. shoulder bursae: a. subacromial b. subcoracoid c. subdeltoid d. subscapular B. Elbow Joint- with articulations involving humerus, radius, and ulna i. humeroulnar joint: largest joint, limited movement, trochlea of humerus and
trochlear notch of ulna
ii. uneroradial joint: smaller joint, capitulum of humerus and head of radius iii. elbow ligaments a. radial collateral b. annular c. ulnar collateral C. Hip Joint- also called the coxal joint, wide range of motion i. ligaments of the hip joint: a. iliofemoral b. pubofemoral c. ischiofemoral d. transverse acetabular e. ligamentum teres D. Knee joint i. artculations: two femur-tibia articulations a. at medial and lateral condyles b. one between patella and patellar surface of femur c. medial and later menisci- fibrocartilage pads, cushion and stabilize 
joint, give lateral support
ii. supporting ligaments a. quadriceps femoris (responsible for extending the knee passes over 
the anterior surface of the joint) 
b. patellar ligament, is made up of patellar retinaculae (two 
ligamentous bands that support the anterior surface of the knee)
