- A point of contact b/t two bones, b/t bone and cartilage, or b/t bone and teeth?
-
a joint
AKA: articulation & arthrosis - Bones that are held together by fibrous connective tissue (that is rich in collagen fibers) are what type of joint?
- fibrous joints
- The bones are held together by cartilage; there is no synovial cavity?
- cartilaginous joints
- The bones forming the joint have a synovial cavity & are united by the dense irregular connective tissue of an articular capsule, and often by accessory ligaments?
- synovial joints
- The functional classification of joints relates to the degree of movement they permit? T/F
- TRUE
- An immoveable joint?
- synarthrosis
- A slightly moveable joint?
- amphiarthrosis
- A freely moveable joint?
- diarthrosis
- The structural classification of joints is based on the presence or absence of a space b/t the articulating bones;synovial fluid, and the type of connective tissue that binds bones together? T/F
- TRUE
- A fibrous joint that only occurs between bones of the skull?
- sutures
- Functionally, sutures are classified as what type of joint?
- synarthrosis
- A fibrous joint in which there is a greater distance b/t the articulating bones and more fibrous connective tissue than a suture?
- syndesmoses
- What is an example of a syndesmosis joint?
-
interosseous membrane
(and the anterior tibiofibular ligament) - Functionally, syndesmosis is classified as what type of joint?
- amphiarthrosis
- A type of fibrous joint in which a cone-shaped peg fits into a socket?
- gomphosis
- An example of a gomphosis joint would be?
- the articulations of the roots of the teeth w/ the sockets of the aveolar processes
- Functionally, gomphosis is classified as what type of joint?
- synarthrosis
- Lacks a synovial cavity and allows little or no movement?
- cartilaginous joint
- A type of cartilaginous joint in which the connecting material is hyaline cartilage?
- synchondrosis
- One example of a synchondrosis joint would be?
- the epiphyseal plate that connects the epiphysis & diaphysis of a growing bone
- Functionally, a synchondrosis joint is classified as what?
- synarthrosis
- A cartilaginous joint in which the ends of the articulating bones are covered w/ hyaline cartilage, but a broad, flat disc of fibrocartilage connects the bones?
- symphysis
- An example of a symphysis joint could be found at the intervertebral joints or at the junction of the manubrium and the body of the sternum? T/F
- TRUE
- Functionally, a symphysis jont is classified as what type of joint?
- amphiarthrosis
- What is the unique characteristic of a synovial joint?
- a space called a synovial (joint) cavity
- Functionally, a synovial joint is classified as what type of joint?
- diarthrosis
- Bones at a synovial joint are covered by by a layer of hyaline cartilage called?
-
articular cartilage
i.e; covers articulating surface but does not bind them.-reduces friction. - Surrounds a synovial joint, encloses the synovial cavity, and unites the articulating bones?
- articular capsule
- The articular is composed of two layers, what are they called?
-
1. outer fibrous capsule
2. inner synovial membrane - Ligaments are found in a fibrous capsule? T/F
- TRUE
