Anatomy Chest Wall

However the muscular layers vary according to the region of the chest wall. Chest wall dysfunction is associated with significant morbidity and rapid life threatening consequences.

Chapter 2 Anterior Thoracic Wall The Big Picture Gross

The chest wall is supplied by the posterior intercostal arteries arising from the aorta the internal thoracic and the highest intercostals given off the subclavian artery and the branches of the axillary artery.

Anatomy chest wall. It originates from the upper borders. The skeleton of the thoracic wall is formed by the twelve thoracic vertebra posteriorly. The chest wall has 10 layers namely skin superficial fascia deep fascia serratus anterior layer for ribs containing intercostal muscles and endothoracic fascia from superficial to deep.

The chest wall is formed from the sternum anteriorly 12 pairs of ribs costal cartilages and intercostal muscles laterally and the thoracic vertebrae posteriorly. Studied the anatomy of the breast its topography innervation vascularization and lymphatic drainage and correlated the anatomical data with the classification of lymph node groups that is frequently utilized by mastologists. Chest wall anatomy the chest is considered to be the area between the neck and the abdomen and contains many major organs as well as muscle groups.

It is made up of the manubrium superiorly the body and the xiphisternum figure 1. The palpable midline sternum is variable in size and shape. The serratus anterior as its name suggests consists of multiple muscle slips that run along the anterolateral chest wall see figure 1 for surface anatomy.

This mri chest thorax axial cross sectional anatomy tool is absolutely free to use. The thoracic wall consists of the osseo cartilaginous throacic cage the interconnecting muscles the muscles on top the fascia the nerves and vasculature the subcutaneous tissue the skin and the mammary glands that lie within the subcutaneous tissue. The chest wall protects the heart lungs and liver provides a flexible skeletal framework to stabilize the actions of the shoulder and arm and promotes respiratory movement all while reliably delivering more than 20000 breaths a day.

At the neck the chest is attached by the three scalene muscles the intercostal muscles and the muscles eminating from ribs 1 and 2 to the vertebral bodies 17.

Some of the chest wall muscles can be used as helpful anatomical landmarks.
