What is the intercostal space?

in anatomy is an inter -stands, often shortened ICS, a space between any two ribs. This term comes from the Latin roots "Inter", which means between and "Costa", which means a rib. People have 12 ribs on both sides, which means that there are 11 intercostal spaces on each side of the chest, numbered from the first to eleventh according to the number of ribs above the space. The inter -stands of the universe is located by a number of different anatomical features.

Each of these spaces contains several layers of intercostal muscles, each with a different specific function. The membrane combines with intercostal combining and plays a key role in breathing. These muscles move through the chest, increase and reduce the size of the chest cavity. The expansion and contract on the chest attracts the air into the lungs and push it over again. The intercontal muscles are surrounded by two membranes called external and internal intercostal membranes. Role in the breathing process. The outer internet muscles raise the ribs and expand the chest cavity for inhalaci. The internal internet muscles reduce the ribs as part of the exhalation. The last layer, the innermost intercostal muscles, contains other muscles that also play a role in inhalation, as well as one, the muscles of the subcostalis, whose function is unclear. Intercontal nerves and arteries are associated with intercostal muscles, supply blood and control their action.

In addition to muscle layers, the intercostal space contains bundles of nerves, veins and arteries. They run together in a group called a neurovascular bundle. The neurovascular bundle runs between the inner and innermost intercostal muscles in the upper part of the intercostal space near the rib. The vein occupies the highest part of the neurovascular bundle with the artery below its nerve at the bottom. As a result of this location, surgical advertising to or through intercostal space usually passes between ribs at low angles to prevent the neurovascular bundle.

u otherAnimal than humans differ in the anatomy of intercostaal space. Some, such as dogs, cats, rabbits and monkeys, have an anatomy very similar to people. In others, however, the muscles of the inter -standing space are arranged very differently, although this function seems to be the same. This is the case of goats and sheep that lacks laminated inter -stands found in humans.
