Arthrology Flashcards
Science of the ligamentous system
Science study of joints and articulations
Arthrology
Other term or synonym of arthrology
Syndesmology
They are formed when 2 or more bones are united by FIBROUS, ELASTIC, OR CARTILAGINOUS or by the combination of the three
Articulation or Joints
A connective tissue bonds that connect muscle to bone
Tendon
A connective tissue bonds that extends from bone to bone
Ligament
It is found within the joints and are surrounded by the synovial membrane
Intracapsular (intra-articular) ligaments
Menisci is found
Intracapsular (intra articular) ligament
It is external to the joint capsule.
It includes collateral, dorsal, palmer, plantar and annular ligaments
Extracellular (periarticular) ligaments
It lies in the medial and lateral aspect of a joint
Collateral ligament
It lies in front of and behind the joint
Dorsal and Palmar (plantar) ligaments
It surrounds the joint and their fibers generally circle the joint to strengthen and protect the capsule
Annular ligament
What are the 2 classification of joints according to number of articulations
Simple joints
Compound bones
- Articulation of more than 2 articulating bones
- Articulation of 2 articulating bones
- Compound joints
- Simple joints
What are the classification of joints based on function
Fibrous joints
Cartilaginous joints
Synovial joints
It has no joint cavity and it is United by fibrous tissue
Fibrous joint ( Synarthrosis)
The three types of fibrous joints
Syndesmosis
Suture
Gomphosis
It has a considerable amount of intervening connective tissue
Ex is the temporohyoid joint
Syndesmosis
It is the joints of the flat bones of the skull
Suture
It is the joints of the flat bones of the skull
Suture
What are the types of suture
Serrated suture
Squamous suture
Plane suture
Foliate suture
Schindylesis
They articulates by means of reciprocally alternating processes and depressions
Serrated suture
One that articulates by reciprocally beveled edges wherein it is a fetal cranium at birth and absorbs shock
Squamous sture
One in which bones meet at an essentially right angled edge or surface
Plane suture
Uneven jagged edges of bones interlock
Schindylesis
A suture with extreme stability
One in which the edge of one bone fits into a fissure or recess of an adjacent bone
Foliate suture
The implantation of teeth in the alveoli
Gomphosis
United by cartilage with no intervening joint cavity
Cartilaginous joint
A type of cartilaginous joint wherein it is usually temporary and is a hyaline cartilage that unites the bone
Synchondrosis, Hyaline cartilage joints/ Primary joints
A fibrocartilage that unites the bone
Symphyses
It facilitates mobility and it is the movable joint in the body
Synovial joint (True joint / Diarthrosis)
Other name for synovial joint
True joint or diarthrosis
the uniting medium of a synovial joint
Joint capsule
Characteristics of joint
Joint capsule
Joint cavity
Articular cartilage
Inner vascular connective tissue
Synovial membrane
Outer and is mainly of yellow elastic tissue collateral ligaments thickening of fibrous layer
Fibrous membrane
It is usually hyaline and it covers articular surfaces with no blood vessels and nerves
Articular cartilage
It is usually hyaline and it covers articular surfaces with no blood vessels and nerves
Articular cartilage
Articular surfaces are plane and allow gliding movement
Plane joints
Articular surfaces are plane and allow gliding movement
Plane joints
A cylindrical surface of one joint fits in the through shape of the other
Ex is the elbow joint.
Hinge joint
The rounded end of one bone forms into a ring formed by the other bone plus a ligament
Trochoid / Pivot joint
The egg-shaped surface of one bone fits into the concave surface of the other
Condylar joint
Opposing joint surfaces are concavo-convex
Saddle joint
Spherical head or one bone fits into the socket of the other
Aka multi axial bone
Ex. Hipjoint and shoulder joint
Ball and socket
And elongation of one surface at a right angle to the other forming an ellipse
Ellipsoidal joint
Rotation of the appendage from the supine position so the palmer or plantar surfaces of the paw faces ventrally
Pronation
Rotation of appendage so the palmer or plantar surface faces medically and dorsally
Supination
2nd most common hick problem
Osteochondrosis
Removal of the distance phalanges through the distal interphalangeal joint in cats
Dewclawing or onychectomy
Formerly known as round ligament of the femur
Ligament of the head of femur
A pathological movement of the tibia cranial to the femur due to rupture of the cranial cruciate ligament
Cranial (anterior) drawer design
The inflammation of stifle
Gonitis
The yes joint
Atlanto-occipital joint
No joint
Atlantoaxial joint
Hock joint
Tarsal joint
