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
Moves structure inferiorly, open mouth
depression
When “nucleolus pulposes” (inner layer of disk) breaks through “annulus fibroses”
Herniated disk
Arm moves lateral, medial
Lateral or medial rotation
Immovable joints
Synarthrosis
Permits movement along 3 axis forward/backward and left/right and rotation.
Triaxial
Spint or twist
Rotation
(Moves toes upward) and plantar flexion (move toes downward)
Dorisflexion
(Bind bone to bone) around outside of joint for strenth; sprain ligaments are stretched
Ligaments
Function is shock absorption
Synovial fluid
Provides nutrients and waste disposal for “chondrocytes”
Synovial fluid
Bones connected by ligaments
Syndesmosis
Adipose tissue that act as packing material that fills space as joint moves (near point)
Fat pad
Bends vertebrae to one side
Lateral flexion
When “anulus fibrosis” Outer layer of disk, is forced out from between vertebrae
Slipped disk
When “nucleolus pulposes” (inner layer of disk) breaks through “annulus fibroses”
Herniated disk
When “anulus fibrosis” Outer layer of disk, is forced out from between vertebrae
Slipped disk

Gomphosis
____________ two bones bound together by cartilage; cartilage bridges ribs and sternum (Cartilage)
Synchondrosis
_________ two bones fuse together (Bony fusion)
Syntosis
_________ is bones connected by ligaments
Syndesmosis
_________ is bones separated by pad of fibrocartilage
Symphysis
Diarthrosis is surrounded by a ________ _______ which contains “synovial fluid” and covered by articular cartilage.
Articular capsule
True or false. Cells do not create waste.
False, all cells create waste
_______ is the pad of cartilage
Meniscus
_______ is adipose tissue that act as packing material that fills space as joint moves
Fat pad
________ bind bone to bone around outside of joint for strength.
Ligaments
________ bind bone to bone around outside of joint for strength.
Ligaments
________ bind muscle to bone, pass around joint and limit the joints range of muscle
Tendons
________ is fluid containing pockets in connective tissue that contain synovial fluid to reduce friction and act as shock absorbers.
Bursae
_________ Permits movement along only ONE axis.
Monaxial
_________ Permits movement along only TWO axis
Biaxial
_________ Permits movement along only THREE axis
Triaxial
_________ Permits movement along only THREE axis
Triaxial
_________ is when Two surfaces move past each other in a single plane. Example?
Gliding
Carpal bone articulations.
_________ is movement in anterior/posterior plane that reduces the angle between the articulating elements
Flexion
________ Occurs in the same plane, but increases angle between articulating elements
Extension
________ is extension past the anatomical position
Hyperextension
________ is extension past the anatomical position
Hyperextension
________ Moves structure superiorly, bite teeth.
Elevation
