The major constituent of connective tissue is the extracellular matrix (ECM). ECM is comprised of
Protein fibres
Ground substance
Epithelial cells
Fibroblasts
The major functions of connective tissue include
binds, supports and strengthens other body tissues.
protects and insulates internal organs.
storage for energy reserves.
provide transport system within the body.
provides sensation through sensory receptors underneath the skin.
Connective tissue is the main source of various immune responses.
Yes
No
What are the main components of connective tissue?
Protein fibres
Cells
Ground substance
Fats
There are three types of protein fibres. These include
Nano fibre
Reticular fibre
Elastic fibre
Collagen fibre
The fibrous components of connective tissue is secreted by
connective cells.
macrophages.
fibroblasts.
epithelial cells.
Collagen protein is the most abundant protein in human body and there are around 28 types. Which type is the mostly found?
Type I
Type III
Type V
Type VII
Sheet-forming collagen that assembles as a lattice-like network in epithelial basal lamina.
Type I
Type II
Type III
Type IV
Which is/are NOT TRUE about collagen fibre?
The strongest and most abundant of all the connective tissue fibres.
Non-elastic but flexible fibre that provides high tensile strength to the matrix.
Has a rubber-like property with significant elasticity.
Renewal of the fibres involve degradation by collagenases.
Occur in organs that require rapid changes of shape/volume e.g. artery, uterus, lymph and GIT layers.
This is a feature of
collagen fibre.
elastic fibre.
reticular fibre.
Elastic fibre is also termed as argyrophilic fibre.
Yes
No
Elastin polypeptides are the major components of elastic fibres.
Yes
No
The cellular components in connective tissue include
fibroblasts.
adipocytes.
chondrocytes.
leukocytes.
Fibroblast refers to the quiescent cell whereas fibrocyte is the active form of fibroblast.
Errrr I'm not sure!
Yes!
Emm..emmm. no...
Monocytes differentiate into macrophages.
Yes!
Nooooo..
Has secretory granules that contain heparin, histamine, serine proteases, cytokines and phospholipid.
Which cell has this feature?
Macrophage
Adipocyte
Mast cell
Fibroblast
The cytoplasma of this cell contain significant amount of neutral fats. This cell refers to
fibroblast
adipose cell.
plasma cell.
macrophage.
Which of the following statements is/are NOT TRUE regarding loose connective tissue?
Forms a layer beneath the epithelial lining of many organs.
Has Type I collagen bundle fibres only.
Contains cells, fibres and ground substance in equal parts.
A flexible tissue and very resistant to stress.
Which of the following statements is/are TRUE regarding dense connective tissue?
Less flexible, hence, not very resistant against stress.
Has high number of fibroblasts that actively secreting the ground substance proteins.
The collagen bundles are aligned in parallel in dense regular connective tissue.
The collagen fibre bundles appear randomly interwoven, with no definite orientation in dense irregular connective tissue.
Leukocytes, also known as migrating cells, are usually not in significant numbers in healthy connective tissue.
Yes
No
