Formation of collagen fibres Flashcards
What type collagen fibres are for bone, tendons and ligaments?
Type 1
What type collagen fibres are for cartilage?
Type 2
What are collagen fibres made of?
Water Fibroblasts Fibrocytes Elastin Collagen Ground substances
What are fibroblasts?
Collagen producing cells
What are fibrocytes?
Mature cells
What are elastin?
Protein with elastic quality
What is collagen?
Great tensile strength
What do the ground substances provide?
Structural stability
Which junction can connective tissue increase strength and load bearing capacity?
Junction between the tendon and the bone surface.
Which body can the connective tissue increase strength and load bearing capacity?
The body of the tendon or ligament
What network can the connective tissue increase strength and load bearing capacity?
Network of fascia within skeletal muscle
TRUE or FALSE. Tendons, ligaments and fascia all respond to resistance training?
TRUE
What is the primary stimulus for growth of the tendons, ligaments and fascia?
Mechanical forces created during exercise
What is the degree of tissue adaptation proportional to?
The intensity of exercise
What does consistent anaerobic exercise that exceeds the threshold of strain stimulate?
Connective tissue changes
Connective tissue increases in size and strength are contributed by what factors?
Increase in collagen fibril diameter
Greater number of covalent cross links within the hypertrophied fibre
Increase number of collagen fibrils
Increased packing density of collagen fibrils
An increase in the size and strength of connective tissues through the contributing factors does what as an overall positive?
Increases tendon stiffness which aids increasing ground reaction force.
What intensity of exercise needs to be performed to stimulate connective tissue adaptations?
High intensity - results in net growth of connective tissue.
