The thorax is commonly known as the chest, whether it is of the human, amphibians, birds, and reptiles. The chest is the part of the body between the abdomen and the head. It is vital for the protection of the vital organs of the chest cavity. It is only therefore right for us to read and know more about the anatomy of the thorax.

The thorax is composed of different structures. Normally, the chest involves the breastbone (sternum), 12 pairs of ribs, and 12 thoracic vertebrae. All these structures work together to protect the organs of respiration and blood circulation. The following are bones that make-up the thoracic cavity.

Within the thoracic cavity lie various organs necessary for our survival which include the lungs, heart, esophagus, stomach, spleen, adrenal gland, pancreas, and other digestive structures.

General Characteristics of the Thorax Anatomy

Anatomy of Thorax
The appearance of the thorax anatomy is conical with the superior part narrower than the inferior part. It is longer at the front and flat at the back. The posterior aspect of the thorax lays the spinal column. At the anterior aspect, you can find the sternum which is flat and slightly curved. The lateral aspect consists of the ribs and the intercostal space. These spaces are filled with muscles and membranes.

Difference between Male and Female Thorax

The male and female anatomy has many differences. The thorax anatomy of the male is bigger and has a larger capacity. Females have shorter breastbones with its level is on the third thoracic vertebra while the male has the breastbone’s margin at the second level of the thoracic vertebra. Since females undergo pregnancy, their ribs are more movable compared to men.

Diseases and Disorders of the Thorax Anatomy

Disorders of the Thorax Anatomy
While the thoracic cavity performs a good job in protecting various organs, it is inevitable that it could sustain damage. Chest injury is one of the most common results of vehicular accidents killing millions of people around the world every year. Chest pain is also a common manifestation of cardiovascular diseases. When the respiratory system is compromised, fluid may fill the chest cavity and flail chest may happen. It is very crucial that an individual would consult his or her physician when early symptoms are experienced.

Summary of Anatomy of the Thorax

The thorax is undeniably a great structure necessary for our survival. It protects internal organs and indirectly assists in body movements. It is composed of different bones that are design to be both strong and flexible. There are differences between the chest of male and female.

If we are not careful, our thorax could be subject to diseases and disorders. It is therefore very important for us to understand the thorax anatomy and how to take care of it.
