Ch 9: Joints
Synarthrosis is a _________________ joint.
immovable
Amphiarthrosis is a _______________ joint.
slightly movable
Diarthrosis is a _______________ joint.
freely movable
Suture, Gomphosis, Synchondrosis, and Synostosis are four types of ________________ joints.
synarthrotic
A ___________ is found only between bones of skull. The edges of bones interlock and are bound by dense fibrous connective tissue.
Suture
________________ is a fibrous connection (periodontal ligament) that binds teeth to bony sockets.
Gomphosis
____________ is a rigid cartilaginous bridge between two
bones
found between vertebrosternal ribs and sternum.
Also,
epiphyseal cartilage of growing long bones
Synchondrosis
______________ is created when two bones fuse.
Example: metopic
suture of frontal bone and epiphyseal lines of mature long bones
Synostosis
What is a type of amphiarthroses joint that is bones connected by a ligament?
Syndesmosis
What is a type of amphiarthroses joint that is bones connected by fibrocartilage?
Symphysis
Which type of joint is freely movable?
synovial joint
___________________ has the consistency of egg yolk, contains
proteoglycans and the primary functions include:
Lubrication
Nutrient distribution
Shock absorption
Synovial fluid
___________ is the fibrocartilage pad between opposing bones the medial is most damaged.
Meniscus
Which joint results from the fusion of two bones?
synostoses
The annulus fibrosus and nucleus pulposus are structures that are associated with __________.
intervertebral discs
The metacarpal and metatarsal bones articulate with the fingers and the toes, respectively. This creates what type of synovial joint?
ellipsoid
Hinge is a _______________.
monoaxial joint
Ball-and-socket is a _____________.
triaxial joint
ellipsoidal is a __________________.
Ex: wirst
biaxial joint
Gliding is a _____________________.
nonaxial joint
_______________ is pad of fibrocartilage that may channel the flow of synovial fluid
Meniscus
_______________ protects articular cartilage and acts as packing material for the joint
Fat pad
_________________ interconnects articulating bones and passes outside capsule
Extracapsular ligaments
_____________________ support the wall of the joint from inside the capsule
Intracapsular ligaments
_________________ although not part of the articulation, pass around the capsule and limit the range of motion
Tendons
____________ reduce friction and act as shock absorbers
Bursae
____________ is when bones are separated by a pad of fibrocartilage
Symphysis
_______________ forms when a joint becomes completely converted to bone
Synostosis
____________ is when bones are joined by a rigid bridge of cartilage
Synchondrosis
_____________ joins humerus to scapula
Glenohumeral
________________ joins clavicle to scapula
Acromioclavicular
_____________ joins radius to carpal to radius and ulna
Radiocarpal
Intervertebral articulations are __________.
gliding joints that permit small movements
____________________ joints are found only between thoracic vertebrae and ribs and allow slight elevation and depression of the ribs.
Costovertebral
The ___________________ between the sacrum and coxae are gliding diarthroses that permit only slight movement.
sacroiliac joints
The _________________ joint is an ellipsoidal diarthrosis that allows flexion and extension.
atlanto-occipital
