VETA 101 - General Arthrology Flashcards
Formed by the union of two or more bones by fibrous, elastic or cartilaginous tissue or a combination of these tissues?
Articulation or joint
- Bone segments are united by a fibrous tissue
in such a manner as to preclude movement? - There is NO JOINT CAVITY
Synarthrosis (Fibrous joint)
3 classes in synarthrosis?
Sutures
Syndesmoses
Gomphoses
- A fibrous joint that is largely confined in the bones of the skull?
Sutures
Depending on the shape of the apposed edges,
sutures can be divided into:
Serrate suture (sutura serrata)
Squamous sutures (sutura squama)
Plane sutures (sutura plana)
Foliate suture (sutura foliata)
- Articulates by means of a reciprocally alternating processes and depressions?
- Found where stable and non
compressible joints are needed
Serrate suture (sutura serrata)
- Articulates by overlapping or reciprocally beveled edges
- Slight degree of compressibility is advantageous?
Squamous sutures (sutura squama)
Bones meet at essentially right angled
edge or surface?
Plane sutures (sutura plana)
The edge of the bone fits into a fisure or recess of another bone?
Foliate suture (sutura foliata)
- The connecting medium is a white fibrous or elastic tissue or a combination?
Syndesmosis
In advancing age of animals, there is ossification of the connective tissue. The
process is known as?
Syntosis
- This term is applied to the
attachment of teeth in the
alveoli. - The periodontal ligament is a
specialized fibrous joint that
attaches the enamel of the
tooth to the alveolar bone of
the socket.
Gomphosis
–Union of this type maybe formed by a
fibrocartilage or hyaline cartilage or a
combination of the two.
Classified as: Synchondrosis (Hyaline cartilage joint) and Symphysis (Fibrocartilagenous joints)
Cartilaginous joints (ampiarthrosis)
- It is sometimes called primary cartilagneous joints
- Usually temporary and represent
persistent parts of the fetal skeleton or secondary cartilages of growing bones.
Synchondrosis (hyaline c.j.)
- Sometimes called secondary cartilaginous joints or ampiarthrosis
- Fibrocartilages in between the contiguous bones may ossify.
- Symphysis (fibrocartilagenous joints)
- These are true joints in the extremities that provide greatest degree of movement.
- More commonly involved in dislocations.
Synovial joint (diarthrosis)
- It is a tube attached around the articulating surface.
- Also known as the capsular ligament.
Joint or articular capsule
It is composed of white fibrous tissue containing yellow elastic fibers.
Fibrous membrane
Thickenings of the fibrous layer of the joint?
Collateral ligaments
- It is usually hyaline cartilage.
- It covers the articular surface of the bones.
- Its deepest part maybe calcified.
- Contains no nerves or blood vessels but capable of regeneration to some extent after an injury or removal.
Articular cartilage
- These are plates of fibrocartilages or dense tissues placed between the articular cartilages.
- They divide the joint into compartments partially or completely.
- Only the stifle and and temporomandibular joints in the dogs posses this.
Articular disc/menisci
- A ring of fibrocartilage that encircles the rim of an articular cavity.
- It enlarges cavity and tends to prevent fractures of the margin.
Marginal cartilages
- It is formed by a special dense bone.
- Smooth and vary much in form.
Articular surface
- Cord or band nearly pure collagenous tissue that connects two or more bones.
- Also used to designate remnants of fetal structure and relatively avascular narrow serous membrane connections.
