Lesson 8 arthrology Flashcards
science of figment systems, also a scientific study of joints and articulations
Arthrology or syndesmology
Form when two or more bones are united by fibrous, elastics or cartilaginous
Articulations or joints
Connective tissue bands that connects muscle to bone
Tendon
Connective tissue that extends from bone to bone
Ligament
Two types of ligament
Intracapsular ligament (intra-articular)
Extracapsular ligament (periaticular)
It is found within joints and surrounded by the synovial membrane
(Cruciate ligaments of stifle)
Intrcapsular ligament
One example of intracapsular ligament
Menisci (fibrocartilage disk)
External to the joint capsule also include collateral, dorsal Palmer, plantar, and annular ligaments
Extracapsular (periarticular) ligaments
Types of extracapsular (periarticular) ligaments
Collateral ligaments
Dorsal and Palmar or plantar ligaments
Annular ligaments
It lies on the medial and lateral aspects of a joint
Collateral ligament
It lies in front of and behind the joint
Dorsal and Balmar or plantar ligaments
Surrounds the joints. Generally circle the joint to strengthen and protect the capsule.
Annular ligaments
Two types of joints
Simple joints (articulation w/ two articulating bones)
Compound joints (articulation with more than two articulating bones)
Three classification on the basis functions of joints
Fibrous joint
Cartilaginous joint
Synovial joint
Give the types of fibrous joint (synarthrosis)
- syndesmosis
- suture
- gomphosis
It is considerable amount of intervening connective tissue also white fibrous or elastic tissue
Give one example
Syndesmosis
Temporohyoid joint
Joints of flat bones of the skull
Suture
Give the types of suture
Serrated suture
Squamous suture
Plane suture
Foliate suture
Schindylesis
If articulates by means reciprocally alternating processes and depression
Serrated suture
Reciprocally beveled edges. Slight degree of compressibility
Give the types of this suture
Squamous suture
- Frontonasal
- Frontomaxillary
- parieto-temporal suture
This which the bones meet at an essentially right angled edge or surface
Give the types of this suture
Plane suture
- Internasal suture
- interincisive suture
This in which the edge of one bone fits into a fissure of an adjacent bone
Give the types of this suture
Foliate suture
-zygomaticomaxillary suture
Uneven jagged edges of bones interlock
Schindylesis
