Tendons and Ligaments Flashcards
What is the role of a ligament and its attachment
Attachment: Bone to Bone
Role: Aid mechanical joint stability, guide joint motion and prevent excessive motion
What is role of tendon and attachment?
A: Muscle to Bone
Role: Transmit tensile strength and help with joint stability
What has more elastin out of the two?
Ligament
Which has more type 1 collagen?
Tendon
How are fibres organised in each connection?
Lig: Random fibre organisation
Ten: Organised fibres
What is the composition of tendon and ligaments?
Dense CT of parallel fibres with fibroblasts synthesising and remodelling ECM
(Tissue sparsely vascularised)
What percentage of ligament and tendons is the ECM?
80%
What surrounds fascicles?
What surrounds tendons?
Endotenon
T: Epitenon
What is the purpose of entheses?
Site of tendon/ligament inserting onto bone
What are 2 types of insertion into entheses and how are they formed?
1) Fibrous: I-M Ossification
2) Fibrocartilage: Endochondral Ossification (Gradual change)
What 3 factors decrease tendon tensile strength?
1) Ageing
2) Immobilisation
2) Pregnancy/Postpartum
How can tensile strength of tendons and ligaments be increased?
Physical Training
