Study Notes

Body Planes and Sections

Sagittal Section: A longitudinal cut dividing the body into right and left parts.
Midsagittal (Median) Section: A cut along the median plane resulting in equal right and left halves.
Frontal (Coronal) Section: A lengthwise cut that divides the body into anterior (front) and posterior (back) parts.
Transverse (Cross) Section: A horizontal cut dividing the body or organ into superior (upper) and inferior (lower) parts.

Body Cavities

Dorsal Body Cavity: Contains the cranial cavity and the spinal cavity, protecting the brain and spinal cord respectively.
Cranial Cavity: The space within the skull that houses the brain.
Spinal Cavity: Extends from the cranial cavity down the vertebral column, enclosing and protecting the spinal cord with vertebrae.

Ventral Body Cavity

Ventral Body Cavity: Larger than the dorsal cavity, containing structures in the thorax and abdomen.
Thoracic Cavity: The superior section of the ventral cavity, separated by the diaphragm; includes the mediastinum, which divides the lungs and houses the heart and trachea.
Abdominopelvic Cavity: Located inferior to the diaphragm, further divided into abdominal and pelvic cavities.

Abdominal and Pelvic Cavities

Abdominal Cavity: Houses vital organs such as the stomach, liver, and intestines.
Pelvic Cavity: Located below the abdominal cavity, containing reproductive organs, bladder, and rectum.
