Study Notes
Directional Terms
- Distal refers to the direction away from the point of attachment
- Proximal is the opposite of distal
- Medial means toward or nearer the midline
- Lateral means away from the midline
- Bilateral means relating to or having two sides
Body Planes
- Vertical planes divide the body into anterior and posterior parts
- Frontal plane (also called coronal plane) divides the body into anterior and posterior parts
- Sagittal plane passes from front to back and divides the body into unequal right and left portions
- Midsagittal plane divides the body into equal left and right halves
Abdominal Regions
- The abdomen can be divided into four sections by a single vertical and a single horizontal line intersecting at the umbilicus
- The four sections are: right upper quadrant (RUQ), left upper quadrant (LUQ), right lower quadrant (RLQ), and left lower quadrant (LLQ)
- The term inguinal refers to the entire lower area of the abdomen, including the groin
Structures of the Body
- The body is composed of cells, tissues, organs, and body systems
- Cells are the basic structural and functional units of the body
- Cells are specialized and grouped together to form tissues and organs
Body Cavities
- The two major body cavities are the dorsal and ventral cavities
- Dorsal cavity contains organs of the nervous system and is divided into cranial and spinal cavities
- Cranial cavity surrounds and protects the brain
- Spinal cavity surrounds and protects the spinal cord
- Ventral cavity contains organs that maintain homeostasis
- Thoracic cavity (chest cavity or thorax) surrounds and protects the heart and lungs
