Human Body Terminology Bio 099 Lab Martini Chapter 1
Anatomy & Physiology • Structure (anatomy) determines function (physiology) "Proportions of the Human Figure" Leonardo da Vinci, 1485-1490
Gross Anatomy(visible to the unaided eye) • surface anatomy
Gross Anatomy(visible to the unaided eye) • surface anatomy • regional anatomy
Gross Anatomy(visible to the unaided eye) • surface anatomy • regional anatomy • systemic anatomy • organ systems
Gross Anatomy(visible to the unaided eye) • surface anatomy • regional anatomy • systemic anatomy • organ systems • developmental anatomy • embryology
Gross Anatomy(visible to the unaided eye) • surface anatomy • regional anatomy • systemic anatomy • organ systems • developmental anatomy • embryology • clinical anatomy • for example radiology
Microscopic Anatomy(cannot be seen without magnification) • cytology • looking at individual cells • histology • looking at groups of specialized cells called tissues • tissues combine to form organs
Physiology • The function of the anatomical structure • Cell physiology • Special physiology (i.e., cardiac) • Systemic physiology (i.e., cardiovascular) • Pathological physiology (Pathos = disease)
Frames of Anatomical Reference • Anatomy uses a special language to describe body sections, regions and relative positions. • You should be familiar with the body terminology in Chapter 1 (pgs 15-22).
Anatomical Position • hands at side, palms facing forward • STANDING FRONT = ANTERIOR • STANDING BACK = POSTERIOR • LYING FACE UP = SUPINE • LYING FACE DOWN = PRONE
Superficial Anatomy • Anatomical Landmarks • Anterior (front) View • Figure 1-6
Superficial Anatomy • Anatomical Landmarks • Posterior (back) View • Figure 1-6
Anatomical Regions • Clinicians use: • abdominopelvic quadrants Provides useful reference for description of pain/injury. RLQ tenderness is a symptom of appendicitis Figure 1-7a
Anatomical Regions • Anatomist use: • 9 abdominopelvic regions Figure 1-7
Anatomical Directional References Figure 1-8
Sectional Anatomy • 3 Sectional Planes • traverse • frontal • sagittal • Plane: • a 3-dimensional axis • Section: • a slice parallel to a plane Figure 1-9
Body Cavities • internal chambers that serve 2 functions • protect organs • permit change in size without distorting or disrupting surrounding tissues or adjacent organs
Ventral Body Cavity (coelom) • Coelom: • divided by the diaphragm into the 1. thoracic cavity 2. abdominopelvic cavity
Membranes Isolate the Organs • Serous membranes: • parietal layer (next to wall of cavity) • visceral layer (next to organ) Figure 1–10b
Thoracic Cavity • thoracic cavity • pleural cavity • divided by the mediastinum • organs: lungs • membranes: visceral and parietal pleura • pericardial cavity • organs: heart • membranes: visceral and parietal pericardium
Mediastinum • mediastinum divides thoracic cavity into 2 pleural cavities Figure 1–10c
Abdominopelvic Cavity • abdominopelvic cavity • peritoneal cavity • membranes: visceral and parietal peritoneum • abdominal cavity (superior peritoneal) • organs: liver, stomach, spleen, intestine • pelvic cavity (inferior peritoneal) • organs: intestine, bladder, reproductive organs.
