The Fallopian Tube

pass into the uterus. If this happens, the embryo may implant in the tube causing a tubal

GROSS DESCRIPTION: Exam of the specimen designated “left fallopian tube” reveals the presence of a fallopian tube measuring 6 cm in length and 2.3 cm in average diameter. Sectioning of the tube shows it to be

In the fetal pig, the heart was enclosed in a pericardial cavity, with the right and left lungs on each side of it (Freeman, et. al). The mediastinum, which includes the pericardium, the esophagus, the trachea, and other structures separates the thoracic cavity into right and left sides (Field, pg. 11). The muscular diaphragm separates the thoracic cavity from the abdominal pelvic cavity, where the digestive and urinary systems are located (Field p. 11). As we worked through the dissection we were able to observe each organ system individually and look deeper into all of the anatomical structures that play a role in its function.

into an early stage embryo while still in a test tube. Scientists place the early stage embryo into

After embryo development, endosperm is growth to store nutrients. This happens after double fertilization, when the triploid nucleus of the ovule’s central cell divides. This causes the formation of a milky multinucleate “supercell”. This becomes multicellular after cytokinesis. Finally, when the cell walls are completed, the endosperm becomes solid.

They extend about 4 inches laterally from either sides of the uterus to the ovaries. It is in the fallopian tubes that fertilization normally occurs. The tube transports the ovum, or egg, from an ovary to the uterus, but the tubes do make direct contact with the ovaries.

in a laboratory setting -- an egg with sperm outside of a woman's womb. Once the embryo develops, it is implanted in a woman's uterus.

The Female Reproductive System structures are the egg / ovum. Its created and stored inside the ovaries. The vagina is an elastic, muscular tube that connects the cervix of the uterus to the exterior of the body. The uterus is a hollow, muscular, pear-shaped organ located posterior and superior to urinary bladder. The Fallopian tubes are a pair of muscular tubes that extends from the left and right superior corners of the uterus to the edge of the ovaries. The ovaries are a pair of small glands about the size

http://kidshealth.org/parent/interactive/frs_it.html In this interactive diagram/demonstration we have pictured the vagina, uterus, fallopian tubes, and the ovaries. When you scroll over a particular part of the picture it will give you the name, what it is, and the function of that part. For instance if you scrolled over the Fallopian Tubes it will tell you that it is a thin soft tube that connects the Uterus to the Ovaries. During ovulation the ovaries will release an egg/s and they will travel through the fallopian tube to the uterus. Essentially it’s the road way. I find this valuable because you can tell someone something about their body all day long but it’s nothing like seeing what it is and how it works for you to

The testicles initially develop in the belly (abdomen). The testicles move down into the scrotum before birth. As they do this, some of the lining of the abdomen comes down as a tube with the testes. This tube connects the abdomen to the scrotum but is usually closed at birth. However, sometimes, it remains open.

Conception: Out of hundreds of eggs and millions of sperm, only one egg and sperm join together at conception. This process takes place in women fallopian tube. The fertilised egg moves to towards uterus to implant in it for next nine months. During this journey, the zygote divides into 12 to 16 cells before reaching the uterus.

During embryogenesis, the testes develop retroperitoneally on the posterior wall of the abdominal cavity. Before birth, they normally descend through the inguinal canal into the scrotum. As they descend into the scrotum, they carry with them a portion of the peritoneum. This peritoneal outpouching, the tunica vaginalis, forms a serous cavity that partially surrounds the anterolateral aspect of each

The main purpose of the oviducts is to be the site of fertilization and receive ovulated oocyte. The oviduct includes the fallopian, or uterine tubes. The ovulated oocyte, or ovum, travels from the ovary to the uterus through the oviduct. The fallopian tube is comprised of three parts, the infundibulum, ampulla and isthmus. The infundibulum is comprised of ciliated fimbriae and located at the cranial end of the fallopian tube. The ampulla, the actual site of fertilization, is located between the infundibulum and isthmus. The isthmus, joined to the uterus, functions as a "container" for sperm. Sperm is released from the mucosa layer of the isthmus.

tubes. Using this, attempts to fertilize the egg outside her body. In vitro fertilization can help women with hopelessly blocked fallopian

The uterine wall on the other hand consists of three separate coats or layers of tissue: The Endometrium (inner one of mucous membrane) is a layer of the uterus that is important in terms of menstrual function and childbearing. It is not a single structure but is rather formed by two layers of cells. The layer closest to the uterine wall, or the basal layer, is not much influenced by hormones. The inner second glandular layer is greatly influenced by both estrogen and progesterone. This is the layer that grows and becomes so thick and responsive each month under the influence of estrogen and progesterone that is capable of supporting a pregnancy. If pregnancy does not occur, this is the layer that is shed as the menstrual flow.
