Question

What is thoracic cavity and its constituents?

Answer 1

Hint: The thorax, often known as the chest, is the area between the neck and the belly in humans, mammals, and other tetrapod creatures. The thorax is one of the three basic divisions of a creature's body, each of which is made up of many segments in insects, crustaceans, and extinct trilobites.

Complete answer:
The thorax, or superior section of the trunk, is placed between the neck and the abdomen and is referred to as the chest. The superior and inferior mediastinal cavities make up the mediastinum. The anterior, middle, and posterior compartments make up the inferior mediastinal cavity. It is made up of various parts:
1. Thoracic wall
2. Several cavities
3. Neurovascular and lymphatics
4. Internal organs
5. Breasts

The thoracic cavity and the thoracic wall make up the human thorax. It houses organs such as the heart, lungs, and thymus gland, as well as muscles and other internal organs. Many disorders can affect the chest, and chest discomfort is one of the most common symptoms.

The thoracic cavity (also known as the chest cavity) is a compartment in the human body that is protected by the thoracic wall (rib cage and related skin, muscle, and fascia) and is limited by the costa and diaphragm.

Note:-
The sternum is an extended bony structure that connects the anterior thoracic cage to the rest of the body. The manubrium, body, and xiphoid process are the three components. The manubrium is the sternum's broader, superior part. The jugular (suprasternal) notch is a shallow, U-shaped border on the top of the manubrium. This can be felt between the medial ends of the clavicles at the anterior base of the neck.
