Chapter 9 Flashcards
Movement away from longitudinal axis of the body.
Abduction
(Bind muscle to bone) pass around joint and limit the joints range of muscle.
Tendons
Occurs in the same plane, but increases angle between articulating elements.
Extension
Freely movable joint
Diarthrosis
Movement toward longitudinal axis of the body
Adduction
Permits movement along only one axis-backward
Monaxial
Movement in anterior/posterior plane that reduces the angle between the articulating elements
Flexion
Pad of cartilage (in joint)
Meniscus
Moves structure posteriorly, slide bottom jaw posteriorly.
Retraction
Moves structure posteriorly, slide bottom jaw posteriorly.
Retraction
Moves structure anteriorly, slide bottom jaw forward.
Protraction
Moves structure anteriorly, slide bottom jaw forward.
Protraction
Lubrication to prevent friction between surfaces
Synovial fluid function (Used 3 times)
Opposition (touch fingers with thumb) allows a person to hold an object
Thumb
Head moves left/right
Left or right rotation
Moves structure superiorly, bite teeth.
Elevation
Attatches coracoids process to the humerus
Coracohumeral ligament
Moving your arm in a circle/loop.
Circumduction
Attatches coracoids process to the clavicle
Coracoclavicular ligament
Has widest range of movement but not very strong; is a ball and socket joint
Glenohumeral joint
Fluid containing pockets in connective tissue that contain synovial fluid reduce friction and act as shock absorbers
Bursae
Extension past the anatomical position
Hypertension
Lubrication to prevent friction between surfaces
Synovial fluid
Extension past the anatomical position
Hypertension
Bones in forearm only (palm face down/face up)
Pronation or suppination
Attatches acromion process to the clavicle
Acromioclavicular ligament
Inversion (foot moves medially) eversion (lateral)
Foot
Bones separated by pad of fibrocartilage
Symphysis
Permits movement along two axis forward/backward and left/right.
Biaxial
Attatches humerus to glenoid cavity/fossa.
Glenohumeral ligament
Movement at an angle
Angular motion
Slightly movable joints
amphiarthrosis
Attaches coracoid process to the acromial process
coracoacromial ligament
