The spelling of the term "canalis obturatorius" is rather complex, with many Latin-rooted syllables that can be challenging to decipher. The correct pronunciation of this word is [kəˈnaːlɪs ɒb.tuːˈraː.tɔ.ri.ʊs], with emphasis on the second, fourth, and seventh syllables. The word refers to an anatomical structure in the pelvic region, and it can be broken down into parts that represent its meaning: "canalis" means "canal," "obturatorius" means "related to or affecting the obturator muscle," which is near this canal.
The term "canalis obturatorius" refers to a specific anatomical structure found in the human body. It is derived from Latin, divided into two words: "canalis," which means "channel" or "canal," and "obturatorius," which is derived from "obturator" meaning "to stop up or block."
In anatomy, the canalis obturatorius is a narrow passageway situated in the upper region of the medial part of the thigh. It is formed by the obturator membrane, a fibrous sheet of connective tissue that fills the obturator foramen, a large hole in the pelvic bone. This membrane forms a partition between the pelvic region and the area of the thigh known as the medial compartment.
The canalis obturatorius serves as a conduit for vital structures, including the obturator artery and vein, as well as the obturator nerve. The obturator nerve is a major nerve that arises from the lumbar plexus and is responsible for innervating the adductor muscles of the thigh, allowing for movement of the legs. The artery and vein provide blood supply and drainage to the structures of the medial thigh.
Understanding the anatomy of the canalis obturatorius is crucial in surgical procedures involving the pelvic region or the medial compartment of the thigh. By knowing its location and the important structures that pass through it, medical professionals can navigate through the area more accurately, reducing the risk of complications during procedures such as hip replacements or hernia repairs.
An opening due to a defect in the upper part of the obturator membrane which closes the obturator foramen.
