Marieb Chapter 8 Joints
Be able to indentify structurs on the Knee Joint, Shoulder Joint, Elbow Joint, and Hip Joint on the study guide.
Terms in this set (66)
Slightly movable joints
Freely movable joints
Movable joints held together by fibrous connective tissue and lack a joint cavity (Sutures, Gomphoses, Syndesmoses)
Thin layer of dense irregular connective tissue bonding articulating bones together. Immovable (Skull)
Root of tooth (no movement)
Collagenous fibers or sheets of fibrous tissue hold bones together at greater distances (Radius and ulna, distal tibia& fibula)
Articulating bones held together by cartilage and lack joint cavities (Synchodroses & Symphyses)
Two bones are joined by hyaline cartilage (epiphyseal plates, 1st rib and sternum <before fusion>)
Two bones are joined by fibrocartilage <pubic symphysis and intervertebral joints>
Movable bones with synovial fluid between the joints. 6 distinguishing features
-Made of dense regular connective tissue that encloses joint cavity
-Lined by synovial membrane that secretes synovial fluid
-Synovial fluid cleans, nourishes and lubricates
Fibrocartilage that cushions and guides articulating bones (knee)
Fibrous sac that contains synovial fluid
Ball and socket joint
Multiaxial; sholder and hip
Biaxial; end of thumb
Biaxial; carpals and tarsels
Monaxial; elbow and knee
Monaxial; ulna and radius & head and atlas vertbre
Decrease the joint angle
Increase joint angle
Extension beyond anatomical position
Away from the midline
Towards the midline
Able to trace a cone-shaped-airspace
Movement around a body part's axis
Movement of body part anteriorly, parallel to the ground
Movement of a body part posteriorly, parallel to the ground
Elevation and depression
Lifting part superiorly or inferiorly
Covers the ends of the articulating bones hyaline cartilage
Space in joint that is filled with synovial fluid
Two-layered structure around joint; consisting of a tough external fibrous layer and an inner synovial layer (makes synovial fluid)
Viscous, slippery fluid that fils all fee space within the joint cavity
Cross synovial joint to strengthen it (capsular, extracapsular, intracapsular)
Elongated bursa that wraps around tendon subjected to friction.
Movements in which flat or nearly flat bone surfaces glide over another.
Movements that increase or decrease the angle between two bones.
Rotation of forearm so that palm faces superiorly. (eat the "soup")
Rotation of forearm so that palm faces inferiorly. ("pro" basketball player)
Upward movement of the foot.
Downward movement of foot.
Turning the sole of the foot medially.
Turning the sole of the foot laterally.
Occurs when you touch your thumb to the fingers on the same hand.
Sleeve-like covering over the synovial cavity
Inner layer; loose areolar CT; Covering joint surface not covered in hyaline
External layer; Dense irregular CT; strengthens so won't pull apart
Attachment of a muscle that remains relatively fixed during muscular contraction. Attached to movable joints
Distal. The more movable of the attachment sites of the muscle. Attached to immovable joints.
small gliding movements, slipping movements of synovial joints, plane
movement in one plane, , Hinge (ginglymus)
movement in two planes , Flexion/Extension and Rotation
One of the range of motions allowed by synovial joints, movement in or around all three planes. Ball- and-socket
Stability sacrificed to make most freely moving joint in the body.
Ball and socket: recall rotator cuff surgery at joint where the humerus head articulates with the glenoid cavity of scapula
Largest most complex joint in the body; allows extension, flexion, some rotation.
Extracapsular: fibular and tibial collateral ligaments( prevent lateral/ medial rotation of knee)
~Medial collateral ligament: prevents lateral movemen
~Lateral collateral Ligament: prevents medial movement
Intracapsular ligaments: cruciate ligaments (cruci=cross; they cross each other forming an x)
~Anterior cruciate ligament: attaches to anterior intercondylar area of tibia
~posterior cruciate ligament: attaches to posterior intercondylar area of tibia
Rheumatoid arthritis, , Granulation tissue that forms over the inflamed synovium and cartilage as a result of accelerated angiogenesis.
inflammation of a joint
An injury to a joint caused by the moving of the joint, such as an ankle or a knee, past its normal and safe end range of motion. With a sprain, ligaments are stretched forcefully, causing tears.
Displacement of a bone from a joint
Inflammation of a tendon
- A bursa is a small, closed bag with a minimum amount of lubricatory fluid that serves as a shock absorber where bones make close contact and to minimize trauma and friction where tendons cross bones and joints. Inflammation leads to pain and immobility in a joint area.
Rest, Ice, Compression, Elevation
INFLAMMATION OF THE BONE AND JOINT
chronic systemic disease characterizd by inflammation of joints, stiffness, pain and swelling
Inflammation and painful swelling of joints caused by excessive uric acid in the body. , Crystals of uric acid form within synovial fluid or joints; interferes with movement
