The term "membrana sterni" refers to a thin layer of tissue that connects the sternum or breastbone to the chest. The spelling of this word is based on its Latin origin and consists of two words: membrana, meaning membrane and sterni, meaning pertaining to the sternum. The correct pronunciation of this term is /ˌmɛm.brə.nə ˈstɜr.ni/, with the emphasis on the second syllable of each word. The IPA phonetic transcription accurately represents the sounds in this term and helps to ensure proper spelling and pronunciation.
Membrana sterni, also known as the sternopleural membrane or the anterior thoracic membrane, is a thin connective tissue that serves as a structural component of the thoracic cavity in humans and other animals. It is a band of firm tissue that spans the space between the sternal ends of the ribs and helps to reinforce the chest wall.
The membrana sterni is primarily composed of dense fibrous connective tissue that provides strength and support to the sternum and ribcage. It acts as a type of ligament, holding the ribs firmly in place and stabilizing the chest during movements such as breathing or physical activity.
This membrane is located on the anterior side of the thoracic cavity, between the costal cartilages of the individual ribs and the sternum. It extends from the costal cartilage of the first rib to the costal cartilage of the seventh rib, although there may be slight variations between individuals.
The membrana sterni plays a crucial role in protecting the underlying organs of the thoracic cavity, such as the heart and lungs. Additionally, it helps maintain the structural integrity of the chest wall, ensuring the proper functioning of the respiratory system.
In conclusion, the membrana sterni is a connective tissue membrane that reinforces the chest wall, providing stability and support to the ribs and sternum.
Sternal membrane, interlacing fibers from the anterior costosternal ligaments covering the anterior surface of the sternum.
