CONNECTIVE TISSUE Flashcards
In which connective tissue matrix, fibers are not a present?
Fluid connective tissue
Statement1: Adipose tissue is also specialised tissue.
Statement2: Adipose tissue stores fats.
Both statement are correct
Choose the odd one out.
Bone, blood, cartilage, adipose
Adipose
What is the function of Macrophage?
Plays a defensive role. (Second line of defence).
What are the two types of fibre in fibroblast?
Collagen fibre and elastic fibre.
What is collagen fiber made up of?
Made up of collagen protein.
What is elastic fibre made up of?
Elastic protein.
What are the features of collagen fibre?
Inelastic
White fibre
Made of collagen protein
Thick and unbranched
Yields gelatin after boiling
Less resistant to chemical change
What are the features of elastic fibre?
Elastic in nature
Yellow fibre
Thin and branched
Donot yeild gelatin after boiling
More resistance to chemical change
Mast cells are the modified form of what?
Basophill cells (a type of WBC)
What are the different types of secretion of mast cells ?
3 types:
Heparin
Histamin
Serotonine
What is the Chemical nature and function of heparin?
Heparin is chemically polysaccride.
Acts as anti cogulant.
What is the chemical nature and function of histamine?
It is chemically peptide.
Acts as vasodialator.
It’s secretion increases during allergy and causes inflammation.
What is the chemical nature and function of serotonine?
It is chemically peptide.
Acts as vasoconstrictor.
What is the function of plasma cell or cartwheel cell?
It forms antibody and hence plays defensive role.
What is the function of areolar tissue?
- Responsible for framing and packing of visceral organs.
- Connects skin (integument) to muscle.
What are the functions of adipose tissue?
- Primary depot of fat in body.
- Source of energy in animals.
- In warm blooded animals, acts as thermoinsulator.
- protects soft organs from external shock.
What is the location of Adipose tissue?
Located beneath the skin.
How many types of adipose tissue are there?
There are two types of adipose tissue , white adipose and brown adipose.
What are the specialities of white adipose tissue?
- monolocular (single fat droplet)
- cytoplasm is less
- appears like signet ring.
- mitochondria is less
- less energy is produced.
what are the specialities of brown adipose tissue?
- multilocular (multiple small fat droplets)
- cytoplasm is more with cytochrome pigment.
- no change in shape.
- more mitochondria.
- produces 14 to 18 times more energy.
appears in infants, rodents and hibernating mammals.
what is the fat storage site in frogs?
corpus adiposem
fat storage site in camel?
hump
fat storage site in whale?
blubber
fat storage site in leech
botryiodal tissue
fat storage site in humans?
panniculus adiposem
Which fibre is present in tendons?
white fibre
what is the function of tendons?
connects muscle to bone.
which fibre is present in ligament?
white as well as yellow.
what are the functions of ligament?
- connects bone to bone as well as cartilage to bone.
- maintains the position of the bones at joints.
in which part of the body bone to bone connection is not made by ligament?
cranium (they are connected by white fibers)
if ligament is cut down then what will happen?
bone will be unfixed.
what is the location of connective tissue proper?
in the dermis of skin.
which tissues are included in connective tissue proper?
loose tissue, dense tissue and few embryonic tissue like mucuos and reticular tissue
