MEDICAL PHYSIOLOGY

Detailed explanation-1: -Fertilization usually takes place in a fallopian tube that links an ovary to the uterus. If the fertilized egg successfully travels down the fallopian tube and implants in the uterus, an embryo starts growing.

Detailed explanation-2: -During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining-a process called implantation.

Detailed explanation-3: -Fertilization occurs at ampulla isthamus junction due to paracrine signalling from tryosine kinase and lactoferrin which is instrumental in combining sperm with ovum.

Detailed explanation-4: -Fertilization of an egg by sperm normally occurs in the fallopian tubes. The fertilized egg then moves to the uterus, where it implants into your uterine lining.
