Explanation: Juxtaglomerulus is a part of endocrine gland. It consists of three types of cells. They are present in kidneys.
5. Who is the father of endocrinology?
a) R H Whittakar
b) Pasteur
c) Thomas Addison
d) Einthoven
View Answer
Explanation: Thomas Addison is the father of endocrinology. In 1921 insulin was discovered and endocrinology became popular.
6. Stress hormone is __________
a) Oxytocin
b) Adrenaline
c) Vasopressin
d) Sex hormone
View Answer
