Terms in this set (43)
Functional Classifications of Joints
Synarthrosis (no movement), amphiarthrosis (little movement), diarthrosis (free movement)
Structural Classifications of Joints
Fibrous, Cartilaginous, Synovial
Joints that are Synarthrodial in function have what structural classifications?
Joints that are Amphiarthrodial in function have what structural classifications?
Joints that are Diarthrodial in function have what structural classifications?
Types of Synovial Diarthroses
Monaxial, biaxial, triaxial
Syndesmosis joint description
Type of joint held together by strong ligamentous structures that allow minimal movement between the bones.
Type of joint separated by a fibrocartilage pad that allows very slight movement between the bones.
Diarthrosis: complex joint bounded by joint capsule and containing synovial fluid, monaxial (elbow, ankle), biaxial (ribs, wrist), triaxial (shoulder, hip)
Types of Fibrous joints
Suture (type of synarthrosis), gomphosis (type of synarthrosis), syndesmosis (type of amphiarthrosis)
Types of Cartilaginous joints
Synchondrosis (amphiarthrosis), Symphysis (amphiarthrosis)
Types of Synovial Joints
mon, bi, triaxial (diarthrosis)
Structural Categories of Synovial Joints (common names)
Gliding, hinge, pivot, ellipsoidal, saddle, ball-and-socket
Structural Categories of Synovial Joints (scientific names)
Ginglymus, Sellar, Trochoidal
Diarthrodial Joint types that move in one axis - one degree of freedom
Diarthrodial Joint types that move in two axes- biaxial -two degrees of freedom
Diarthrodial Joint types that move in three axes-Multiaxial-Three degrees of Freedom
Arthrodial, Enarthrodial, Sellar
Common name for joint classification Ginglymus
Common name for joint classification Trochoidal
Common name for joint classification Condyloidal
Ellipsoid, biaxial ball-and-socket,ovoid
Common name for joint classification Arthrodial
Common name for joint classification Enarthrodial
Ball and Socket, spheroidal
Common name for joint classification Sellar
Arthrodial joint example
carpal bones of the wrist and the tarsometatarsal joints of the foot. ends of clavicles, between carpals, tarsals, cartilage of ribs 2-7 and sternum, and articular facets of adjacent vertebrae
Condyloidal joint example
wrist (radiocarpal joint) between the radius and the proximal row of the carpal bones or the second, third, fourth, and fifth metacarpophalangeal joints
Enarthrodial joint example
shoulder (glenohumeral) and hip (acetabular femoral) joints
Ginglymus joint example
elbow (humeroulnar), ankle (talocrural), and knee (tibiofemoral) joints interphalangeal joints
Sellar joint example
ONLY one example, thumb at carpometacarpal joint.
Trochoidal joint example
rotation of the radius on the ulna at the proximal and distal radioulnar joints.(pronation, supination). atlas and axis (saying no),
Arthrodial joint description
characterized by two flat, or plane, bony surfaces that butt against each other, permits limited gliding movement
Condyloidal joint description
bones permit movement in two planes without rotation.
Enarthrodial joint description
most like a true ball-and socket in that it permits movement in all planes.
Ginglymus joint description
permits a wide range of movement in only one plane
Sellar joint description
This type of reciprocal reception is found only in the thumb at the carpometacarpal joint and permits ball-and-socket movement, with the exception of slight rotation.
Trochoidal joint description
rotational movement around a long axis.
Describe suture joints
Synarthroidal, found in the sutures of the cranial bones. The sutures of the skull are truly immovable beyond infancy.
Describe Gomphosis joints
(type of joint in which a conical peg fits into a socket). Sockets of the teeth. Normally, there should be an absolutely minimal amount of movement of the teeth in the mandible or maxilla.
Describe Syndesmosis joints
Type of amphiarthrodial joints. held together by strong ligamentous structures that allow minimal movement between the bones
Example of Syndesmosis joints
the coracoclavicular joint and the inferior tibiofibular joint.
Describe Symphysis joints
Type of amphiarthrodial joint. Joint separated by a fibrocartilage pad that allows very slight movement between the bones.
Example of Symphysis joints
symphysis pubis and the intervertebral disks.
Describe Syndochrosis joints
Type of amphiarthrodial joint. Type of joint separated by hyaline cartilage that allows very slight movement between the bones.
Example of Syndochrosis
Examples are the costochondral joints of the ribs with the sternum.
