Question

Which one of the following hormones is not secreted in any human chorionic placenta?
A. Progesterone/pregnancy hormone
B. Estrogen and hPL
C. PRL/LTH
D. HCG

Answer 1

Hint:-LH hormones are secreted by the pituitary. That is not secreted by the human placenta. These are hormones initially used in the pregnancy period. LH hormones maintain a corpus luteum. For the LH hormone secretion in progesterone.

Complete answer:
The hormone Prolactin is typically produced by the anterior hypophysis gland. This hormone normally inspires the development of the mammary gland in the duration of pregnancy. It also involves the process of lactation after the birth of the child takes place.
Human chorionic gonadotropin (hCG) is one of the hormones which is secreted by the placenta in a woman while she is pregnant. Human chorionic gonadotropin is a hormone that is produced by the cells that border the budding embryo in a human being. These cells will go on to form the placenta in due course.
Human placental lactogen (hPL) which is also known as human chorionic somatomammotropin, is formed and concealed by the syncytiotrophoblast which is a part of the placenta. The major amount of the hormone Estrogen is typically produced by the placenta and it is estriol. Also, the equestrian placenta which normally synthesizes a unique group of Estrogen hormones is not seen in other animals other than female human beings.
The human chorionic gonadotropin (hCG) (also called as Human chorionic gonadotropin) is a placental hormone which is originally secreted by cells (of syncytiotrophoblasts) from the embedding conceptus during week 2.
Hence, option C is the correct answer.

Note:- The hormone prolactin is also known to be lactotroph. Prolactin is one of the proteins which is known as the best for empowering mammals which are habitually females to produce milk. In over 300 separate processes in various vertebrates which include human beings, it is an influential process.
