Sagittal Midsagittal (median)(midline) Parasagittal Frontal (coronal) Transverse (cross sectional)(horizontal)(transumbilical) Oblique
Sagittal plane
Vertical - right and left sides
Midsagittal plane
Median
Midline
Passes through midline - equal left and right sides
Parasagittal plane
Parallel line - unequal left and right sides
Frontal plane
Coronal
Anterior and posterior portions
Transverse plane
Cross sectional
Transumbilical
Horizontal
Superior and inferior portions
Oblique plane
Any angle other than 90 degrees
Abdominopelvic cavity
Subdivided into abdominal and pelvic cavity
Thoracic cavity
Contains pleural cavity, pericardial cavity, mediastinum
Cranial cavity
Holds brain, formed by skull
Ventral body cavities
Contains Thoracic cavity and abdominopelvic cavity
Organs called viscera, organs covered with serous membrane
Dorsal body cavity
Contains Cranial cavity and vertebral cavity
Meninges line dorsal cavity
Vertebral cavity
Contains Spinal cord, formed by vertebral column
Abdominopelvic regions
Right hypochondriac region Right lumbar region Right inguinal region Epigastric region Umbilical region Hypogastric region Left hypochondriac region Left lumbar region Left inguinal region
Abdominopelvic region lines

6 life processes
Metabolism Responsiveness Movement Growth Differentiation Reproduction
Metabolism
All the biochemical reactions that occur within an organism
Catabolism
The breakdown of complex chemical substances into simpler components
Anabolism
The building up of complex chemical substances from smaller simpler components
Homeostasis
The state of relative stability of the body’s internal environment
Stress
The mental and physical condition that occurs when a person must adjust or adapt to the environment
Anatomical levels of organization within the human body
Chemical -atoms & molecules Cell Tissue Organs System-organs work together with common function Organism-any living thing
Anatomical position
Standing facing observer, eyes forward, feet flat and directed forward, upper limbs at side, palms facing forward
