Introduction to Human Anatomy

• Human anatomy is the medical science concerned with the study of structure and relationship to functions of its constituent parts.
• The term "anatomy" was derived from a Greek word meaning "to cut up."
• The anatomy of every structure in the body is adapted for performing one or more functions.

Disciplines in Anatomy

• Macroscopic/Gross/Topographic
• Microscopic/Histology
• Developmental/Embryology
• Neuroanatomy/Brain and Nervous system

Brief History of Anatomy

• Primitive Times
  • Illness and diseases were viewed as punishment from gods.
  • First physicians were witch doctors using ceremonies to treat illness.
  • Herbs and plants were used as early pharmaceuticals; for example foxglove for strengthening and slowing the heart.
• Greeks (1200 BC - 200 BC)
  • Made observations about the human body and effects of disease, contributing to modern medical science.
  • Believed illness resulted from natural causes.
  • Used therapies such as massage, herbal treatments, and discovered that diet and cleanliness could prevent disease.
  • Explained illness in terms of four humors (Blood/Sangius-Liver, Phlegm/Phlegma -lungs, Yellow bile/Chole -Gallbladder, Black bile/Melanchole -Spleen), believed to be governed by Air, Water, Fire, and Earth.
  • Bloodletting was popular to rid the body of excess humors.
• Egyptians (3000 BC - 300 BC)
  • Used leeches for bloodletting (draining blood)
  • Leech saliva contains a natural anesthetic, a blood thinner, a vasodilator, and an agent preventing bacteria from infecting the wound.
• History of Anatomy (Greece)
  • The Greeks were the first to attempt to study the human body objectively.
  • Many medical terms are based on Greek language
• Claudius Galen (120c to 200AD)
  • Roman physician, team doctor for gladiators.
  • Kept gladiators alive so they could fight again.
  • Proved that arteries carry blood, and not air.
  • Believed blood originated in the liver and flowed outwards to the flesh.
  • Believed three organs controlled the body: Liver-produced physical pneuma in veins, Heart-produced vital pneuma in arteries, Brain-produced psychic pneuma in nerves.
• Leonardo Da Vinci (1452-1519)
  • Artist, painter, philosopher, and scientist.
  • Interested in human form, studied and dissected human bodies.
  • Created anatomically correct drawings.
• Andreas Vesalius (1514-1565)
  • Belgian physician.
  • Corrected many of Galen's anatomical errors.
• William Harvey (1578-1657)
  • Advanced the premise that all animals develop from eggs.
  • Father of Anatomy studied the circulatory system.
  • Dissected his own family members.
• History of anatomy (Rome)
  • Human dissections were forbidden.
• Shortage of cadavers
  • Medical schools in England and Scotland; no one donated bodies, and churchgoers feared this affected the chances of resurrection.
  • Executed criminals sometimes were used.
• Grave robbing:
  • Medical students raided graveyards to get bodies. In some cases, bodies were traded for tuition
• Resurrectionists
  • By 1828 body snatchers (Resurrectionists) in London provided the medical schools with corpses. This was not a crime; a dead body couldn't be owned.
  • Anatomy studies were conducted primarily from October to May.
• William Burke and William Hare (Circa 1828) - 2 Resurrectionists - Killed 15, possibly more - Used to provide bodies for anatomical studies
• Anatomy Act of 1832
  • Bodies of the poor could be used by anatomists
• Our Experience
  • Cadavers are bought from mortuaries.
  • Current debates on the necessity of dissection in medical studies.

Anatomical Terminology

• Anatomy and medicine have an internationally recognized vocabulary using Latin or Greek.
• Terms are used to avoid ambiguity and for smooth communication in health care and related fields.

Anatomical Position

• Standard reference position of the body.
• Standing erect, feet together, palms forward, facing forward.
• Universal method to describe location and structure.
• The Supine and Prone positions; are sometimes needed to provide specific detailed anatomical descriptions.

Anatomical Planes

• Median plane: divides the body into left and right halves.
• Sagittal plane: parallel to the median plane.
• Coronal plane: perpendicular to the median plane, divides the body into front and back portions.
• Transverse plane: divides the body into upper and lower portions.

Terms of Relationships

• Various adjectives or pairs of opposites describe the relationship of structures of the body and to each other.
• Terms like Superficial, intermediate, and deep are used.
• Medial and lateral are terms also used in description of position of structure to each other; in relation to a median plane.

Terms of Movements

• Angular movements; increase or decrease the angle between articulating bones.
  • Flexion
  • Extension
  • Abduction
  • Adduction
  • Dorsiflexion
  • Plantarflexion
  • Hyperextension
• Circular movements; involve rotation and circumduction.
  • Rotation
  • Circumduction
• Special movements; include inversion, eversion, opposition, protusion, retraction, elevation and depression, pronation and supination.
