How Do You Spell PLACENTAL COMMISSURA?

Pronunciation: [pləsˈɛntə͡l kəmˈɪʃəɹə] (IPA)

The word "placental commissura" can be a challenge to spell due to its technical nature. The word refers to the point at which blood vessels merge in the placenta. Its spelling begins with the sound of "pl" and then is followed by "ey" as in "play", and "s" as in "sun". The final part of the word sounds like "al" and then "ko-mih-shur-uh". To make things easier, one could use the phonetic transcription written as /pləˈsɛntəl kəˈmɪʃərə/ to help spell and pronounce it correctly.

PLACENTAL COMMISSURA Meaning and Definition

1. Placental commissura, also known as the placental septum or placental barrier, refers to a specialized anatomical structure found in the placenta of mammals. The placenta is the organ that develops in the uterus during pregnancy, allowing for the exchange of nutrients, gases, and waste products between the mother and the developing fetus. Within the placenta, the placental commissura serves as a dividing wall or septum that separates the maternal blood supply from the fetal blood supply.

   The primary function of the placental commissura is to ensure the necessary exchange of substances between the mother and the fetus while preventing direct mixing of their blood. It consists of layers of cells that create a physical and biochemical barrier between the two circulatory systems. This barrier allows for the diffusion of oxygen, nutrients, and hormones from the mother's blood into the fetal blood, while simultaneously removing waste products such as carbon dioxide and urea from the fetal blood into the maternal blood for disposal.

   The presence of the placental commissura is crucial for maintaining a healthy environment for the developing fetus. It protects the fetus from potential harmful substances in the mother's blood, such as certain drugs or toxins, while also preventing the mother's immune system from recognizing the fetus as foreign and attacking it.

   In summary, the placental commissura is a specialized tissue within the placenta that acts as a barrier between the maternal and fetal blood supplies, allowing for essential exchanges while protecting the fetus and maintaining a healthy pregnancy.

2. Posterior commissure, posterior gray commissure, the portion of the gray commissure of the spinal cord lying posterior to the central canal.
