Interkostalnerna

Interkostalnerna is a term that refers to the intercostal spaces, the areas between the ribs in the human body. These spaces are important anatomical features that play a crucial role in various physiological processes.

The intercostal spaces are subdivisions of the thoracic cavity, the space within the thorax that contains the heart, lungs, and other vital organs. The ribs, which are long, flat bones that provide protection for the vital organs, are separated into intercostal spaces by intervening cartilages. There are 11 pairs of ribs, and each pair is separated by an intercostal space.

The intercostal spaces contain a variety of structures, including intercostal muscles, blood vessels, and nerves. The intercostal muscles, which include the external, internal, and innermost intercostal muscles, help to control the expansion and contraction of the lungs during breathing. The blood vessels in the intercostal spaces supply oxygen and nutrients to the surrounding tissues and organs. The nerves in the intercostal spaces transmit sensory information from the skin and internal organs to the brain.

Understanding the intercostal spaces is important in various fields, including anatomy, physiology, medicine, and physical therapy. Knowledge of the intercostal spaces is essential for healthcare professionals to diagnose and treat conditions affecting the thoracic cavity and surrounding tissues.
