TOPIC 3 - CONNECTIVE TISSUE (INTRODUCTORY) Flashcards
Give the 5 types of connective tissue.
- Embryonic
- Connective tissue proper
- Cartilage
- Bone
- Blood
It is a type of connective tissue formed during the development of the embryo.
Embryonic connective tissue
Sub-divisions of embryonic connective tissue
- Mesenchyme (in embryos)
- Mucoid connective tissue (umbilical cord)
This embryonic connective tissue develops into the various connective tissues of the body.
Mesenchyme
This embryonic connective tissue is a gelatinous substance.
Mucoid connective tissue
Which embryonic germ layer is mesenchyme part of?
Embryonic mesoderm
What are the functions of connective tissues?
- Binding and support
- Protection
- Insulation
- Transportation
Give the 3 characteristics of connective tissue.
- Mesenchyme as their common tissue of origin
- Varying degrees of vascularity
- Nonliving extracellular matrix, consisting of ground substance and fibers
Give the 3 structural elements of connective tissue.
- Ground substance
- Fibers
- Cells
This is unstructured material that fills the space between cells.
Ground substance
What are the three types of fiber?
- Collagen
- Elastic
- Reticular
What is the composition of ground substance of connective tissue?
Note: 3 answers
- Interstitial fluid
- Adhesion proteins (fibronectin and laminin)
- Proteoglycans (glycosaminoglycans)
This type of fiber is tough and provides high tensile strength.
Collagen
This type of fiber is long and thin that allows for stretching.
Elastic
This type of fiber is a branched collagenous fiber that form delicate networks.
Reticular
These cells of connective tissue is found in connective tissue proper.
Fibroblasts
These cells of connective tissue is found in cartilages.
Chondroblasts
These cells of connective tissue is found in bones.
Osteoblasts
