3?

Definition

A.  Synarthrosis-  immovable joint 

 

B. Amphiarthrosis-  Little movement joints 

 

C.  Diarthrosis -  highly removable joint 

Term
Structural classifications
Definition

 Syndesmosis 

 

 Suture 

 

 Gumphosis

 

Schindylesis

Term
Syndesmosis
Definition

 -Considerable space between bones 

 

- United by inter interrosseous membrane or ligament 

 

-  Little movement possible 

 

-distal tibiaofibula joint

Term

 Suture 

 

 Classify 

&

5 types

Definition

= to sew

 

-  bones are very close together 

 

-  United by a small amount of dense connective tissue 

 

-  immovable?? 

 

-Serrate, Denticular, Squamous, Limbus, and Plane

Term
Serrate
Definition

 Edges are serrated 

 

 Sagittal suture -  parietal bones 

Term
Denticular
Definition

 Tooth like

 

 Lambdoidal -  parietal and occipital bones 

Term
Squamous
Definition

 Bones overlap 

 

Squamous surure -  temporal and parental 

Term
Limbus
Definition

 Overlap and serrated 

 

 Parietal and frontal bone 

Term
Plane
Definition

Apposition of rough surfaces

 

 Maxilla and zygomatic 

Term
Gomphosis
Definition

(gomphos = nail)

 

 Peg and socket held together by fibrous connective tissue 

 

 Roots of the teeth in the maxilla and mandible 

Term
Schindylesis
Definition

( splintering )

 

 Rigid bone fits into a groove 

 

Vomere and sphenoid

Term
Cartilaginous joints
Definition
Bones joined by cartilage ( hyaline, elastic, fibrous)
Term
Hyaline cartilage joints
Definition

(synchondrosis)

 

 Usually primarily cartilaginous joints that appear in the up at the epiphyseal plate. They are temporary joints that are later replaced by bone.

Term
Fibrocartilageous Joint
Definition

(Symphsis)

 

grown together

Term
This is the secondary cartilaginous joint for the bones are united by fibrocartilage that persists throughout life
Definition

 Pubic synthesis 

 

 Vertebral disc 

Term
Synovial joints
Definition

( Diarthrosis )

 

 Contains a joint cavity that separates bones 

Term
Types of synovial joints
Definition

 Simple =  two articulating surfaces 

 

 Compound = more than two 

 

complex = includes a meniscus

Term
Translocation = ?
Definition

 

gliding joint, plane joint

 

services are flat or slightly concave / convex

 

-  vertebral column 

-  Intercarpal / intertarsal joints 

Term

 

Another name for hinge joint

Definition

Ginglymus joint

 

 Movement is limited to one plane, flexion and extension 

 

- Humeroulnar joint

- Interphangeal

- Knee - sort of.....  It actually has a small amount of rotation 

Term
Longitudinal axis
Definition

Torchoid joint (pivot joint)

 

 Central bony pivot surrounded by an osteoligamentous ring.

 

- movement is rotations around a longitudinal axis which passes through the pivot. Movement is rotations around a longitudinal axis which passes through the pivot 

 

 pivot rotates - example;

 Radial ulna joint

ring rotates around pivot - example - Alantoaxial joint

 

 

Term
Biaxial
Definition
Movement can occur around two axis at right angles to one another
Term
Condyloid joint
Definition

 Hey convex surface articulates with the concave surface. The main movement is flexion and extension. However there may be a small amount of rotation 

 

- Metacarpalphangeal

-Atlanto-occipital (sometimes)

 

Biaxial 

Term
Ellipsoid joint
Definition

 Similar to a condyloid except surfaces are elliptical. Movements include; flexion\extension, abduction/abduction and in circumduction but NO rotation 

 

-radio-carpal joint

-Atlanto-occipital (sometimes)

Term
Sellar joint
Definition

(Saddle joint)

 

 Shaped like a saddle with both a concave convex surface. Movements are the same as ellipsoidal but seller has greater amount of movement .

Term
Multiaxial
Definition
Movement can occur around three axes
Term

Spheroid joint (Ball and socket)

 

 Roundhead that fits into a cup like cavity. Movement includes; flexion/extension, abduction/adduction, circumduction and rotation.

 

 Glenohumeral joint and Femoroacetabular joint
