FA - Connective Tissue Flashcards
(22 cards)
Name some examples of connective tissue
Bone, ligament, fat, blood
Describe the structure and function of collagen
Consists of protein - collagen
Resistant to tension
Arranged in bundles
Allows some flexibility as not taut
Describe some features of Elastic Fibres
Made of Elastic
Can be stretched to 150% of relaxed length without breaking
What suffix is used to describe the immature class of cell
Blast
WHat suffix is used to name the mature class of cell
Cyte
What is the function of chondroblasts
To secrete the matrix
What is the function of Chondrocytes
To maintain the matrix
What is the Matrix
The Matrix is a non- cellular substance and is made up of ground substances and protein fibres
What is the structure of the ground substance
Can be fluid or solid, composed of proteogylcans and water and is amorphous
What is the purpose of the ground Substance
It supports cells by providing a medium for substance exchange and binding cells together
Where would Hyaline Cartilage be found
At the ends of bones e.g. at the bottom of the femur
And it also lines joints such as the knee joint
Where would Fibrocartilage be found
Forming discs and rings between joints e.g. the spinal chord
Name the other type of Cartilage
Elastic Cartilage
Describe the function of Hyaline cartilage
Covers articulai surfaces at joints
Reduces Friction,
Absorbs shock
Describe the features of Fibrocartilage
Has great strength, some elasticity and bundles of thick collagen fibres provide strength
Name the 2 Types of Dense connective tissue
Dense regular
Dense irregular
What is the role of Dense Regular Connective Tissue
Provides strong attachments between structures
Provides great tensile strength in 1 direction
What is the structure of dense regular connective tissues
Collagen fibres in parallel bundles
A few elastin fibres
Give examples of Dense regular connective tissue
Ligaments - bone to bone - stabilise joints
Tendons - muscles to bone - transmits tensile load form muscle to bone
What is the role of Dense irregular connective Tissue
Provides strength in multiple directions, holds muscle together and separates muscles into functional groups
What is the structure of Dense irregular connective tissue
Collagen fibres randomly arranged, a few elastin fibres
Name 2 examples of dense irregular Connective Tissue
deep fascia - sheet of connective tissue surrounding and protecting muscles
Joint Capsule - envelope surrounding synovial joint
