What is caudal margin placenta?
The caudal margin placenta, also known as the caudal placenta, refers to a type of placentation where the placenta is positioned towards the back (caudal) end of the developing embryo. This term is often used in the context of certain species in veterinary medicine, particularly in the study of animal reproductive biology. The arrangement can influence nutrient transfer and overall fetal development, depending on the species and its reproductive adaptations.
Do sponge have a placenta?
No, sponges do not have a placenta. Sponges are simple, multicellular organisms that belong to the phylum Porifera and lack complex organ systems, including reproductive structures like a placenta. They reproduce primarily through asexual means or by releasing sperm and eggs into the water for external fertilization. As a result, their reproductive processes are very different from those of more complex animals that do have placentas.
When and by whom placenta was invented?
The placenta is a part of the female reproductive system and was not invented by anyone. The first mammals known to have had placentas lived about 160 million years ago in the late Jurassic period.
What place where the embryo develops?
The embryo develops in the uterus of the female reproductive system. It implants into the lining of the uterus and receives nutrients and oxygen from the mother through the placenta.
What is the medical term meaning abnormal implantation of the placenta?
Placenta previa, placenta accreta, placenta increta, and placenta increta are all conditions stemming from abnormal implantation of the placenta.
What type of placenta does an orange have?
Oranges do not have placentas. Placentas are only found in mammals, where they play a crucial role in providing nutrients and oxygen to the developing fetus. Fruits such as oranges have a different type of reproductive structure called ovary or carpel, which protects the seeds and aids in their dispersal.
Do platypuses have a placenta?
Male lizards have two reproductive organs, called hemipenes. Only one at a time is used during mating. The male simply mounts the female, often grabbing her by the neck or side, and inserts one into her cloaca, then they remained locked together for a while. It is a much less active affair than what is seen in mammals or birds. Some species lay leathery or hard-shelled eggs, while others give live birth.
Do cats have a placenta?
Placenta comes out after each kitten.
Do earthworms have a placenta?
Nope - Earthworms are hermaphrodites - in that they have both male and female reproductive organs. During mating they exchange sperm - and lay eggs a few days later which hatch into tiny earthworms.
To which structure does the umbilical cord connect the embryo?
The umbilical cord is attached to the placenta and the placenta is attached to the wall of the uterus
Can the placenta move during pregnancy?
Yes. But the movement is relative. Placenta does not change the position. But lower placenta may move up. So that placenta previa may become normal placenta.
