Study Notes
Anatomical Position
- Upright posture with feet flat on the floor.
- Facing forward, palms facing anteriorly.
- Supine orientation if lying on the back.
Directional Terms
- Right and Left: Used to describe positions relative to the body.
- Superior (cephalic/cranial): Refers to a position higher than another part.
- Inferior (caudal): Refers to a position lower than another part.
- Anterior (ventral for bipeds): The front of the body.
- Posterior (dorsal for bipeds): The back of the body.
- Medial: Closer to the midline of the body.
- Lateral: Farther from the midline of the body.
- Ipsilateral: Same side of the body.
- Contralateral: Opposite side of the body.
- Intermediate: Between two structures.
- Proximal: Closer to the point of attachment or trunk.
- Distal: Farther from the point of attachment or trunk.
- Superficial (external): Closer to the body's surface.
- Deep (internal): Further from the body's surface.
Planes of the Body
- Transverse: Divides the body into superior and inferior parts (cross-section).
- Sagittal: Divides the body into left and right parts (includes midsagittal and parasagittal).
- Coronal (frontal): Divides the body into anterior and posterior parts.
Abdominopelvic Regions
- Nine-region system includes:
- Hypochondriac: Upper lateral regions.
- Epigastric: Central upper region.
- Lumbar (Lateral): Middle lateral regions.
- Umbilical: Central region around the navel.
- Iliac (inguinal): Lower lateral regions.
- Hypogastric: Central lower region.
- Quadrant system divides the abdomen into four sections based on the umbilicus.
Body Cavities
- Dorsal Cavity:
- Cranial Cavity: Houses the brain.
- Vertebral (spinal) Cavity: Encases the spinal cord.
- Ventral Cavity: Subdivided by the diaphragm.
- Thoracic Cavity: Contains heart and lungs.
- Pericardial Cavity: Surrounds the heart.
- Pleural Cavity: Surrounds each lung.
- Mediastinum: Contains the heart, great vessels, and trachea.
- Abdominopelvic Cavity: Divided by an imaginary line from pubis to sacrum.
- Abdominal Cavity: Contains digestive organs.
- Pelvic Cavity: Contains reproductive organs and bladder.
- Thoracic Cavity: Contains heart and lungs.
