Chapter 1: Human Biology Planes & Cavities Chapter 1: Human Biology

Sagittal Section Divides body into right and left parts Cut down the medial plane into equal parts= midsaggital or median section

Frontal Section Divides body into anterior (front) and posterior (back)

Transverse Section Divides body into superior (upper) and inferior (lower) parts

Dorsal Cavities (posterior) Cranial: inside skull brain Spinal: extends from cranial cavity to end of vertebral column Spinal cord

Ventral (anterior) cavities Thoracic: inside rib cage above diaphragm Lungs, heart

Abdominopelvic: inferior (below) the diaphragm Abdominal: superior Stomach, liver, intestines Pelvic: inferior Reproductive organs, bladder, rectum

Umbilical: center (navel) Epigastric: above umbilical Hypogastric (pubic): below umbilical Right and Left Iliac (Inguinal): right above hip Right and Left Lumbar: lateral to umbilical Right and Left Hypochondriac: contain lower ribs, lateral to epigastric
