Liver
The tissue which forms the basic structure of lymphoid organs, like bone marrow, spleen, etc. is
Reticular tissue
Which is the principle cation in the plasma of blood?
Sodium
Polycythemia is the abnormal increase in? problematic how?
Erythrocytes. Increased number makes blood viscous and can precipitate heart failure.
WBCs are more in number or RBCs?
600:1 ratio. RBC more in number.
Would it be wrong to say that ciliated epithelium is found in trachea and Fallopian tubes
Ciliated epithelium (simple) is found in bronchioles and Fallopian tubes whereas Ciliated pseudostratified columnar is specifically present in trachea and bronchi, pharynx.
Sesamoid bone example
Patella
TENDON IS
WHITE FIBROUS CONNECTIVE TISSUE (collagen)
Stratum germinatum has?
Columnar cells
Hair loss is more in old age due to?
Decreased blood supply
When muscles contract, which zone’s length decreases
H- Zone
Give different types of globulin
there’s alpha, beta and gamma.
interestingly, antibody is another name given to gamma globulins.
Two reasons why nucleus and organelles are absent in RBCs. what’s the irony?
obviously 1). to increase oxygen carrying capacity
2). to decrease oxygen consumption
the one which is tasked with supplying oxygen doesn’t get to use it
From evolutionary point of view which tissue originated first?
Epithelial tissue
The gall bladder and bile duct are lined by?
Simple columnar epithelium
Describe the germinative layer of transitional epithelium
TRICK OR TREAT
Transitional epithelium lacks both basement membrane and germinative layer.
True coelom is covered by
Mesoderm
Zymogen cells are found in
Stomach
(Zymogen is an inactivated precursor of an enzyme and is stored in zymogen granules which are found in acinar cells of pancreas and salivary glands also/ zymogen granules are found in the cytoplasm of secretory cells)
~acinus (pl. Acini): small sac like cavity in a gland which is surrounded by secretory cells

Do frogs have brown fat?
No, humans and small rodents do.
Describe brown fat cells. Comment on their oxidation power wrt yellow fat
They are multilocular with a looot of mitochondria and are polygonal in appearance. They are found in hibernating mammals like rat and other rodents and in new born humans.
~their oxidation power is 20 times more than that of yellow fat
Collagen fibres are found maximum in? (Ligaments, tendons, cartilage, bone)

Seen in: tracheal and bronchial rings, larynx, nasal septum, coastal end of ribs, articular surfaces at joints of long bones
Sternum, sternal part of ribs too
Vertebrae of shark has which cartilage
Calcified cartilge (also: suprascapula of frogs)
Hyoid apparatus is made
Hyaline
Bone marrow is composed of
Adipose, Areolar tissue and blood vessels
Normal haemopoiesis in frogs occurs in

MESENCHYME refers to
Term coined by Hertwig, refers to all tissues in adult body derived from mesoderm
Superficial layer of dead cells in skin is called
Stratum corneum
FUN FACT: Horns of mammals are formed by stratum corneum of the skin
Why does ageing occur
Due to deterioration of connective tissue
Why do ancient mummies still have their arteries intact?
Due to well preserved elastic fibres
