What is implantation class 12

Implantation is the process that occurs in the female after fertilisation. Mostly, implantation takes place on the 7 th day after fertilisation. A woman is not said to be pregnant when there is successful implantation. If implantation does not occur, the thickened endometrial lining sheds off to form a woman’s menstrual period. Implantation takes place in five stages namely, hatching, adplantation, apposition, adhesion, and invasion. The symptoms of implantation are observed after 6−10 days generally after conception. In this article, we will provide detailed information about Implantation. Read on to find out! Fig: Fertilized Egg Development What is Implantation? After fertilisation, i.e., the fusion of male and female gametes, a female is said to be conceived and the zygote formed travels down into the uterus, which after a series of cleavage divisions becomes the morula. Typically, morula or little mulberry is a \(16\)-celled stage. Fig: Blastocyst Morula changes to the blastocyst, which burrows itself into the lining of the uterus and forms a connection with the maternal tissue to get nourishment for its growth and development. This process is called implantation. Progesterone Hormone will remain high throughout the gestation period which is responsible for further thickening (up to \(5\)) of the endometrial lining. Blastulation is the process of development of the morula prior to implantation. The young embryo (morula) reaches the uterus; its outer cell begins to abso...

The fertilised egg (zygote) soon starts developing and by the time it reaches the uterus, a small ball of numerous cells is already formed. This is a kind of embryo which forms a pit in the wall of the uterus and gets fixed in it. This natural way of fixing of the embryo in the wall of the uterus is called implantation. This produces the state of pregnancy.

Hint: Implantation is the term which is for the process of attachment of blastocyst, which is the stage of an embryo formed in the fallopian tube travels to the uterus and attached to the endometrium of the uterine wall, and this happens after 7th day of fertilization. What is significance of implantation class 10? Complete answer: Implantation refers to the attachment of the fertilized egg to the uterine lining and it is also defined as the stage of parental development. It is the movement of the cells to a new region. In terms of embryology, the attachment of the early embryo to the lining of the uterus. What is implantation explain? Implantation: The act of setting in firmly. In embryology, implantation refers specifically to the attachment of the fertilized egg to the uterine lining, which occurs approximately 6 or 7 days after conception (fertilization). Many medical devices or materials may be implanted (embedded). What does implantation mean in science? Implantation is defined as the process by which the embryo attaches to the endometrial surface of the uterus and invades the epithelium and then the maternal circulation to form the placenta. What is implantation by Ncert? After attachment, the uterine cells divide rapidly and covers the blastocyst. As a result, the blastocyst becomes embedded in the endometrium of the uterus (Figure 3.11h). This is called implantation and it leads to pregna...

On the sixth day following fertilisation, the blastocyst gets attached to the wall of uterus in such a way that the side of inner cell mass is positioned against the endometrium. The trophoblast cells produce some enzymes that help the embryo to 'eat its way' into the thick endometrium. This begins the process of implantation. By the seventh to tenth day following implantation, the blastocyst is completely embedded or implanted in the endometrium.

Fertilization and implantation 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.

They have their whole life ahead of them! Actually, that’s not really true. While most of their life is still ahead of them — including life stages of infancy, childhood, adolescence, and adulthood — this newborn baby is not just starting out in life. They are already nine months old, and what happened to them during those nine months will help shape the rest of their life. Some of the shortest — but most important — life stages occur before birth. These stages include the germinal, embryonic, and fetal stages. This concept focuses on the earliest of all human life stages: the germinal stage. Figure \(\PageIndex\): newborn What Is the Germinal Stage? Figure \(\PageIndex\) and described in detail in the rest of this concept. The germinal stage lasts a total of eight to nine days. It begins in a Fallopian tube when an ovum is fertilized by a sperm to form a zygote (day 0). The germinal stage continues as the zygote undergoes several initial cell divisions to form a solid ball of cells called a morula (days 3-4). It then continues as the mo...
