The investigators could distinguish human hair from animal hair by the patter of pigmentation and by the medullary index.
The pigmentation in human hairs is denser toward the cuticle, whereas in animal hair is denser toward the medulla. Human hairs are usually one colour throughout the whole length, while animal hairs may change colour suddenly.
The medulla in humans is thinner than in animals: the medullary index for human hairs is 0.33 or less; the medullary index for animal hairs is 0.5 or more.
Answer:
<u>B) Polycystic kidney disease</u>
Explanation:
<u>A) Hypospadias</u>
It is a congenital disease characterized by an abnormal urethral opening on the dorsum of penis.
<u>B) Polycystic kidney disease</u>
It is a disease characterized by the multiple cysts in the kidney as implied by the name.
<u>C) Cystitis</u>
It is defined as the infection of urinary bladder.
<u>D) Dysuria</u>
It is defined as painful urination. It can be due to infection or other underlying disease.
<u>E) Epispadias</u>
It is a congenital disease characterized by an abnormal urethral opening on the ventral surface of penis. It is much less common than hypospadias.
<u>CORRECT ANSWER</u>
From the options, the most appropriate answer is <u>B) Polycystic kidney</u> as it is a disease characterized by the formation of cysts in the kidney. These cysts obstruct urinary flow.
They increase the permeability of the lymph capillaries. Interstitial fluid enters the lymphatic vessels through the mini valves (which are overlaps of endothelial cells
from multiple lymph capillaries). The valves also prevent the backflow of the lymph from the vessels back to the tissues.
