Medical Terminology Body Organization

Biological Organization Cell - the basic unit of life Tissue - a group of like cells that work together to perform a function Organ - a group of tissues that work together to perform a function

Biological Organization Organ system - a group of organs that work together to perform a function (functions) Organism - an entire living thing

Biological Organization There are four types of tissue found in humans: epithelial connective muscle nervous

Biological Organization There are a variety of organs that make up eleven different human organ systems

Anatomical Positions & Directions Anatomists, those in the medical community and others use directional terms to describe body positions and directions

Anatomical Positions & Directions These directional and positional terms are applied using the standard anatomical position

Anatomical Positions & Directions Planes frontal transverse median (sagittal) Transverse Frontal Median

Anatomical Positions & Directions Anatomical directions: anterior (ventral) posterior (dorsal) Frontal

Anatomical Positions & Directions Anatomical directions: superior (cephalic) inferior (caudal) Transverse

Anatomical Positions & Directions Anatomical directions: lateral medial proximal distal Median

Anatomical Directions

Anatomical Positions & Directions External regions: RUQ LUQ RLQ LLQ

Anatomical Positions & Directions Internal regions: hypochondri ac epigastric lateral umbilical  hypogastric  inguinal

Anatomical Positions & Directions Body cavities: dorsal - cranial - vertebral ventral - thoracic - abdominal - pelvic

Anatomical Positions & Directions Thoracic cavity: pleural pericardia l mediastinu m Diaphragm

Body Membranes The membranes that line the body cavities and cover the internal organs are named for the organs or regions that they cover

Body Membranes Membranes that line the body cavities are called parietal membranes Membranes that cover internal organs are called visceral membranes

Body Membranes

Body Membranes

Anatomical Positions & Directions Some common root words and combining forms: abdomin(o) (abdomen) thorac(o) (chest)  cephal(o) (head)  encephal(o) (brain)  viscer(o) (visceral)

Anatomical Positions & Directions Some common root words and combining forms: omphal(o) (umbilicus) pelv(i) (pelvis)  caud(o)(tail)  acr(o) (extremities) dactyl(o) (digits)

Anatomical Positions & Directions Be able to recognize or write the meanings of the abbreviations at the end of the chapter
