Chapter 9 - Articulations Notes Flashcards
Chapter 9 - Articulations
joints are named
according to the bones or portions of bones that are united at the joint
Chapter 9 - Articulations
joints are classified by
major connective tissue type that binds
whether or not there is a fluid-filled joint capsule
function
Chapter 9 - Articulations
_____consist of two bones that are united by fibrous connective tissue, have no joint cavity, and exhibit little or no movement
fibrous joints
Chapter 9 - Articulations
fibrous joints are classified by
basis of sutures, syndesmoses, or gomphoses
Chapter 9 - Articulations
_____ are seams between the bones of the skull, and some sutures may be completely immovable.
suture
Chapter 9 - Articulations
_____ results when 2 bones grow together across a joint to form a single bone
synostosis
Chapter 9 - Articulations
a ______ is a type of fibrous joint in which the bones are further apart than in a suture and are joined by ligaments
syndesmosis
Chapter 9 - Articulations
_____ are specialized joints consisting of pegs that fit into sockets and that are held in place by fine bundles of regular collagenous connective tissue
gomphoses
Chapter 9 - Articulations
__________ unite two bones by means of either hyaline cartilage or fibrocartilage.
cartilaginous joints
Chapter 9 - Articulations
__________ consists of two bones joined by hyaline cartilage
synchondrosis
Chapter 9 - Articulations
________ consists of fibrocartilage uniting two bones.
symphisis
Chapter 9 - Articulations
______ those containing synovial fluid, allow considerable movement between articulating bones
synovial joints
Chapter 9 - Articulations
the articular surfaces of bones within synovial joints are covered with a thin layer of hyaline cartilage called
articular cartilage
Chapter 9 - Articulations
additional fibrocartilage _________ are associated with several synovial joints such as the knees and the TMJ. They provide extra strength and support to the joint
articular disks
Chapter 9 - Articulations
asynovial joint is enclosed by ________ which helps to hold the bones together while allowing for movement.
joint capsule
Chapter 9 - Articulations
the joint capsule has an outer layer called
outer fibrous capsule
Chapter 9 - Articulations
the joint capsule has an inner layer called
inner synovial membrane
Chapter 9 - Articulations
in certain synovial joints the synovial membrane may extend as a pocket or
bursa
Chapter 9 - Articulations
there are ___ types of synovial joints
6
Chapter 9 - Articulations
typs of synovial joints
plane (or gliding) saddle hinge pivot ball and socket ellipsoid
Chapter 9 - Articulations
the movements of synovial joints can be describe as occuring on ____ axis
mon
bi
multi
Chapter 9 - Articulations
movement is best described in relation to the anatomic position.
movement away from anat position
movement returning toward anat position

Chapter 9 - Articulations
____ is rotation of palm so that it faces anteriorly
supination
Chapter 9 - Articulations
___ combines flexion, extenion, abduction, and adduction

elevation
Chapter 9 - Articulations
_____ moves inferiorly
depression
Chapter 9 - Articulations
____ consists of moving in an anterior direction
protraction
Chapter 9 - Articulations
______ moves the structure back to anat position or even more posteriorly
retraction
Chapter 9 - Articulations
______ refers to the moving of the mandible right/left
lateral excursion
Chapter 9 - Articulations
_______ returns mandible to neutral position
medial excursion
Chapter 9 - Articulations
_____ unique movement of the thumb and little finger. Occurs when 2 digits are brought toward each other across the palm
opposition
Chapter 9 - Articulations
______ movement of returning thumb and little finger to the neutrall anat position
reposition
Chapter 9 - Articulations
____ turning of the ankle so the plantar side faces medially toward the opposite foot
inversion
Chapter 9 - Articulations
______ turning the ankle so the plantar side faces laterally
eversion
