Pars membranacea

Pars membranacea is a term used in anatomy to refer to the membranous part of various structures in the human body. It is derived from Latin, where "pars" means part and "membranacea" means membranous. This term is often used to describe parts of the body that are thin, flexible, and often semi-transparent, similar to a membrane.

Anatomy[edit | edit source]

In anatomy, the term pars membranacea is used to describe the membranous part of various structures. For example, the trachea has a pars membranacea, which is the posterior part of the trachea that is not supported by cartilaginous rings. This part of the trachea is flexible and allows for the expansion and contraction of the trachea during breathing.

Another example is the pars membranacea of the fallopian tubes, which is the part of the fallopian tubes that is closest to the ovary. This part of the fallopian tubes is thin and flexible, allowing for the movement of the egg from the ovary to the uterus.

Clinical significance[edit | edit source]

The pars membranacea of various structures in the body can be affected by various diseases and conditions. For example, the pars membranacea of the trachea can be affected by tracheomalacia, a condition where the trachea collapses due to the weakening of the tracheal walls. This can lead to difficulty breathing and other respiratory symptoms.

The pars membranacea of the fallopian tubes can be affected by ectopic pregnancy, a condition where a fertilized egg implants outside of the uterus, often in the fallopian tubes. This can lead to severe abdominal pain and other complications.
