Study Notes

Anatomical Organization

The human body is organized into several systems, including:
- Integument
- Skeletal
- Muscular
- Nervous
- Endocrine
- Cardiovascular
- Lymphatic

Directional Terms

Proximal refers to a location that is:
- Toward or nearest the trunk or the point of origin of a part
- Example: the proximal end of the femur joins with the pelvic bone

Body Cavities

The two main cavities are:
- Ventral cavity
- Dorsal cavity
The ventral cavity is:
- The larger cavity
- Subdivided into two parts by the diaphragm
- Thoracic cavity
- Abdominopelvic cavity
The abdominal cavity contains:
- Most of the gastrointestinal tract
- Kidneys
- Adrenal glands
The dorsal cavity is divided into two portions:
- Cranial cavity (upper portion)
  - Houses the brain
- Vertebral canal (lower portion)
  - Houses the spinal cord
