Study Notes

Body Cavity Overview

The thoracic cavity contains the heart, thymus, esophagus, trachea, and large blood vessels, and extends from the first rib to the diaphragm.
The cranial cavity is formed by the cranial bones and contains the brain.
The abdominopelvic cavity can be divided into smaller areas using two methods: quadrants and nine regions.

Anatomical Planes

The sagittal plane divides the body into right and left parts.
The frontal plane divides the body into anterior (front) and posterior (back) parts.
The transverse plane divides the body into superior (above) and inferior (below) parts.
The four imaginary planes used to divide the body into sections at right angles to each other are the sagittal, frontal, transverse, and midclavicular planes.

Abdominopelvic Cavity

The abdominopelvic cavity can be divided into quadrants by the transumbilical plane and the midclavicular lines.
The subcostal plane aligns posteriorly in relation to the body at the level of the 10th rib.
The linea alba is an imaginary line that runs down the midline of the abdomen.

Mediastinum and Serous Membrane

The mediastinum is a region in the thoracic cavity that contains the heart, esophagus, trachea, and large blood vessels.
The function of the mediastinum is to separate the thoracic cavity into two parts.
The peritoneum is the serous membrane that lines the abdominal cavity.
The function of the peritoneum is to separate the abdominal cavity from the abdominal organs.

Body Cavity Separation

Structures that separate the various body cavities from one another include the diaphragm, sternum, and vertebral column.

Additional Information

Quadrants are more commonly used by clinicians due to their ease of use and simplicity.
The nine-region method of dividing the abdominopelvic cavity is more widely used for anatomical studies.
