- Anterior: Indicates the front of the body; also known as ventral.
- Posterior: Refers to the back of the body; also known as dorsal.
- Medial: Suggests closeness to the midline of the body.
- Lateral: Describes a position further from the midline.
- Proximal: Refers to being closer to a limb's attachment point.
- Distal: Indicates being farther from a point of attachment.
- Superficial: Relates to structures close to the body's surface, such as skin and hair.
- Deep: Refers to structures located further inside the body, like organs.
Body Regions
- Upper Limbs: Comprise the upper arm, forearm, wrist, and hand.
- Lower Limbs: Include the thigh, lower leg, ankle, and foot.
- Central Limbs: Consist of the head, neck, and trunk.
Body Planes
- Sagittal Plane: Divides the body into right and left portions.
- Median Plane: A specific sagittal plane that bisects the body into equal right and left halves.
- Transverse Plane: A horizontal section that separates the body into superior and inferior sections.
- Frontal Plane: A vertical division that separates the body into anterior and posterior parts.
Body Cavities
- Dorsal Body Cavity: Encloses the nervous system organs.
- Cranial Cavity: Houses and protects the brain.
- Vertebral Canal: Contains the spinal cord.
- Ventral Body Cavity: Major subdivision comprising the thoracic and abdominopelvic cavities.
Thoracic Cavity
- Space within the chest wall and diaphragm.
- Mediastinum: The central compartment, located between the lungs.
- Serous Membrane: Covers walls and organs within thoracic and abdominopelvic cavities.
- Parietal Layer: Lines the walls of the body cavity.
- Visceral Layer: Envelops the organs.
Different Serous Membranes
- Pericardiac Cavity: Encloses the heart.
- Pleural Cavity: Houses the lungs.
- Peritoneal Cavity: Contains many internal organs like the liver and elements of the digestive and reproductive systems.
Subdivision of the Abdomen
Quadrants
