1. The Human Body What is Anatomy? What is Physiology?
The study of the form, or structure of body parts.
What is Physiology?
The functioning of the body’s structural machinery.
Hierarchy of Structural Organization.
Atoms > Cells > Tissues > Organs > Systems > Organism

2. Organ Systems Integumentary – skin, hair - protection
Skeletal – protects and supports organs
Muscular – allows movement
Lymphatic – dispose of debris, houses WBC
Immune – protects body
Reproductive – to reproduce

3. Organ Systems Respiratory – gas exchange
Nervous – control and responds to external and internal change
Endocrine – glands secrete chemicals which regulate body process
Cardiovascular – transports blood
Digestive – breaks down food, eliminates waste
Urinary – eliminates nitrogenous wastes, balance of the blood

4. The language of Anatomy
Anatomical Position – body erect, palms and toes forward.
Directional Terms – Table 1-9 (page 15)
Superior, inferior
Anterior, posterior
Medial, lateral, intermediate
Proximal, distal
Superficial, deep

5. Body Planes and Sections:
Sagittal – longitudinally, divided into left and right portions.
Midsagittal – midline
Parasagittal – beside
Frontal (coronal) logitudinally, divided into anterior and posterior portions.
Transverse – horizontally, divided into superior and inferior parts
Oblique – intermediate between a horizontal and longitudinal plane.

6. Body Cavities Dorsal – includes cranial and vertebral cavities.
Ventral – includes the thoracic and abdominal pelvic cavities.
Oral, Nasal, Orbital, Middle ear, and Synovial cavities.

7. Terminology
Serosa – double layer membrane lining cavity walls and organs.
Parietal – membrane close to body cavity.
Visceral – membrane close to an organ.
Pleural – pertaining to the lungs
Pericardial – “ “ to the heart
Peritoneum – “ “ to the abdominal cavity.
