Arthrology - Adding Complexity Flashcards
How much movement is common for a synarthrosis?
No movement - considered immovable
How much movement is common for an amphiarthrosis?
Very little movement but some movement possible
How much movement is common for a diarthrosis?
Highly moveable
What functional classification is a fiberous joint?
Synarthrosis
What are the types of fiberous joints?
Syndesmosis
Suture
Gomphosis
Schindylesis
What is characteristic of a syndesmosis?
United by interosseous membrane
Considerable space between articulating bones
Little movement allowed
What is characteristic of suture joints?
Bones are united by dense connective tissue are are very close together.
Considered immovable
What are the different types of suture joints?
Serrate Denticular Squamous Limbus Plane
Describe the characteristics of a serrate suture joint.
Edges are primarily serrated along joint
Describe the characteristics of a denticular suture joint.
Edges are primarily smooth with (a) toothlike projection(s)
Describe the characteristics of a squamous suture joint.
Bones are quite thing and are overlapping
Squamosal suture
Describe the characteristics of a limbus suture joint.
Overlapping and serrated bone
Describe the characteristics of a plane suture joint.
Apposition of rough surfaces
What is an example of a serrate suture joint?
Parietal Bone
What is an example of a denticular suture joint?
Parietal and Occiptal Bone
What is an example of a squamous suture joint?
Temporal and Parietal
What is an example of a limbus suture joint?
Parietal and Frontal
What is an example of a plane suture joint?
Maxilla and Zygomatic
What is characteristic of a gomphosis joint?
Peg and socket - held together by fibrous connective tissue
What is an example of a gomphosis joint?
Roots of teeth in mandible and maxilla
What is characteristic of a schindylesis joint?
Ridged bone that fits into a groove
What is an example of a schindylesis joint?
Vomer and sphenoid
What is another name for a serrate suture joint?
Sagittal Suture
What is another name for a denticular suture joint?
Lamdoidal Suture
What is another term for a squamous suture joint?
Squamosal Suture
What is characteristic of a hyaline cartilage joint?
Primary Cartilagenous
At a later point - ossifies
What is characteristic of a fibrocartilagenous joint?
Secondary Cartilagenous
Maintains Cartilagenous articulation even after full development
What is an example of a hyaline cartilage joint?
A primary Cartilagenous joint that later ossifies - epiphyseal plate in bone
What are a few examples of a fibrocartilagenous joint?
Pubic symphysis
Intervertebral Discs
What are the classifications of synovial joints?
According to the articulating surfaces
According to the amount of movement/shape
What are the types of synovial joints according to the amount of movement in the joint and its shape?
Translocation
Uniaxial
Biaxial
Multiaxial
What are the types of synovial joints according to the articulating surfaces?
Simple
Compound
Complex
