“Trunk Region (Torso)”  

Trunk (Torso)

  In our body, the Trunk Region (Torso), an anatomical term for the central part of the body, is a combination of both the thoracic region (chest), including the mammary region (breasts), and the abdomen region (belly region) including the naval (umbilicus region), coxal region, and pubic region.
  In our body, the Trunk Region (Torso) as an anatomical term for the central part of the body, including the thoracic region (chest) and abdomen region (belly region), from which extends (but are not included) the neck, the upper limbs and the lower limbs.
  Examples of subsets, concepts, subjects and related entities of include:

“Thoracic Region (Thorax Region)”  

Thorax Region (Chest Region)

  In our body's trunk region (torso), the Thoracic Region (Thorax Region) is the trunk region that encompasses the chest from the thoracic inlet to the diaphragm (thoracic diaphragm), which includes the area of the external chest and the internal thoracic body cavity (chest cavity) protected by the rib cage (thoracic cage).

Visceral Structures of the Thorax

  In our body's torso, the organs of our Thorax Region (Chest) include the;

• mammary glands (breasts)
• rib bones (ribs) and sternum bone (breastbone)
• lungs
• heart
• mediastinum
• esophagus (oesophagus)
• diaphragm (thoracic diaphragm)
• thymus gland.

Internal and External Structures

  

Internal Structures of our Thorax Region (Chest)

In our body's torso, the Internal Structures of our thorax region (chest) include the diaphragm, esophagus, trachea and xiphoid process (metasternum).

External Structures of our Thorax Region (Chest)

In our body, the External Structures of our Thorax Region (Chest) include the Breast, Nipples and Mammary Glands. **

“Mammary Region (Breasts)”  

Breasts

  In our body's trunk region, the paired Mammary Region (Breasts), in the front of the chest encompassing each breast and housing the mammary glands, composed mainly of skin, muscles, fat (adipose tissue), breast tissue and connective tissue, nerves, veins, and arteries.
  In and on our body's chest, each Breast contains 15 to 20 lobes arranged in a circular fashion. The fat (subcutaneous adipose tissue) that covers the lobes gives the breast its size and shape. Each lobe is comprised of many lobules, at the end of which are tiny bulb like glands, or sacs, where milk is produced in response to hormonal signals. Ducts connect the lobes, lobules, and glands in nursing mothers. These ducts deliver milk to openings in the nipple.
  In our body, each Breast is located in the upper ventral region of the torso and is part of the External Structures of the Thorax Region (Chest). **

“Abdomen Region (Abdominal Region)”  

Abdomen

  In our body's lower trunk region (torso region), the Abdomen in the abdomen region (belly region) encompassing the stomach area is the portion of the body that lies between the thorax and the pelvis.
  In our body, the abdomen contained within the abdominal cavity surrounded by the abdominal wall which houses many organs.
  

Examples of subsets, concepts, subjects and related entities of abdomen include:

“Pubic Region”  

  In our body's lower trunk region, the Pubic Region is a region that encompasses an area above the genitals. **

“Umbilical Region (Naval Region)”  

Umbilicus Region

  In our body's lower trunk region, the Umbilicus Region (Naval Region) is the area located at the center of the abdomen region (belly region) surrounding the navel (umbilicus). **
