Study Notes

Anatomical Position

Defined as upright posture, facing forward
Arms are positioned at the sides with palms also facing forward

Body Planes

Three primary planes: transverse, midsagittal, frontal
Transverse plane divides body horizontally into upper and lower parts
Midsagittal plane divides body vertically into equal right and left halves
Frontal plane divides body vertically into front (anterior) and back (posterior)

Spatial Terms

Superior: Refers to structures above the transverse line
Inferior: Refers to structures below the transverse line
Cranial: Indicates locations toward the head
Caudal: Indicates locations toward the tail/end of the spine
Medial: Body parts situated toward the midsagittal line
Lateral: Body parts situated away from the midsagittal line
Ventral: Refers to parts toward the front of the body
Dorsal: Refers to parts toward the back of the body
Proximal: Indicates closeness to the body trunk
Distal: Indicates distance from the body trunk

Body Cavities

Body cavities are spaces that house vital organs
Dorsal cavity: Located at the back
- Divided into cranial cavity (housing the brain) and spinal cavity (housing the spinal cord)
Ventral cavity: Located at the front
- Divided into thoracic cavity (chest containing trachea, bronchi, lungs, heart, and major blood vessels), abdominal cavity (stomach, intestines, liver), and pelvic cavity (reproductive organs, bladder, rectum)

Smaller Cavities in the Skull

Orbital cavity: Contains eye structures
Nasal cavity: Contains nasal structures
Oral cavity: Houses teeth, tongue, and mouth structures

Abdominal Cavity Regions

Divided into nine regions:
- Epigastric: Upper middle section
- Umbilical: Center section
- Hypogastric: Lower middle section
- Left hypochondriac: Upper left section
- Right hypochondriac: Upper right section
- Left lumbar: Middle left section
- Right lumbar: Middle right section
- Left iliac: Lower left section
- Right iliac: Lower right section
