Lecture 9 Flashcards
What is fibrous joint and what is its role?
A fibrous joint is made 2 bones bound together via ligaments, and allows for little movement and aims to hold structures together, an example of a fibrous joint is the cranial suture.
What is a cartilaginous joint and what is its role?
A cartilaginous joint is a joint made up of fibrous cartilage, and its primary role is keep structures stable but allow for some movement. e.g. the intervertebral discs (structure) and pubic symphysis (joint)
what is a synovial joint and what is its role?
Allows for movement and is mostly located at the limb joints.
What is the capsular ligament, where is it found and what does it provide.
The capsular ligament is a DFCT that runs from one bone to another, and is thick and tight where more support is required, and loose where movement is allowed (joints).
What is the ‘space’ between the articular cartilage of 2 bones called and what purpose does it serve?
This space is called potential space or cavity, and is not really empty, but filled with synovial fluid which helps the articular cartilage of the 2 bones on the joint to run smoothly across one another.
Where is synovial fluid secreted from?
From the synovial membrane which lines the inner surface of the capsule.
What are the collateral ligaments of the knee and what do they do?
The ligaments on the medial and lateral side of the knee joint.
The medial restricts abduction.
The lateral restricts adduction.
What is the cruciate ligament and which direction does that posterior and anterior ligament restrict movement in?
Located in the middle between the two heads of the Femur, and stops the Femur from rubbing anteriorly and posteriorly against the Tibia and Fibula.
The anterior cruciate ligament restricts posterior movement of the Femur.
The posterior cruciate ligament restricts anterior movement of the Femur.
