Basic Human Anatomy Honor

Science & Health

Requirements

1. What is human anatomy?

   Answer: Human anatomy is the science that studies the structure of the human body: bones, muscles, organs, systems (nervous, circulatory, digestive, etc.) and their spatial relationships. It is the basis of medicine and the health sciences. — Human anatomy was systematized by Andreas Vesalius in 1543 in 'De Humani Corporis Fabrica,' considered the founding work of modern anatomy, which replaced the texts of Galen used since classical antiquity.

2. How did the study of human anatomy begin? What techniques are currently used for the study of anatomy?

   Answer: 1) How the study began: it arose in ancient Egypt (~3000 BC) with mummification, which required opening and knowing the body; Hippocrates (~460 BC) systematized the studies in Greece. 2) Techniques used today: dissection (cadavers), magnetic resonance imaging, computed tomography, 3D ultrasound, and virtual/digital models (such as the Visible Human Project). — The Visible Human Project, started by the U.S. National Library of Medicine in 1989, was the first completely digitized human body in 1mm slices, the basis of 3D anatomy software used globally in medical schools.

3. What is the anatomical position, what does it look like, and what is its importance? Illustrate.

   Answer: The anatomical position is the standard reference: body standing, gaze forward, arms extended at the sides of the body, palms facing forward, feet together with toes pointing forward. — The anatomical position was standardized by the Belgian anatomist Andreas Vesalius in the 16th century and adopted universally as a fixed reference for the precise description of structures in any person, regardless of their actual momentary position.

4. What are the basic components and main functions of each of the systems below? Present images that illustrate each of them.
   • Circulatory system;
   • Digestive system;
   • Respiratory system;
   • Skeletal system.

   Answer: 1) Circulatory system: the components are the heart (pump), the arteries (carry oxygenated blood), the veins (return blood to the heart), the capillaries (where exchanges occur), and the blood. Function: to transport oxygen, nutrients, and hormones and to remove waste. 2) Digestive system: the components are the mouth, the esophagus, the stomach, the small and large intestines, with the liver and pancreas as accessory glands. Function: to digest food, absorb nutrients, and eliminate waste. 3) Respiratory system: the components are the nose, the pharynx, the larynx, the trachea, the bronchi, and the lungs (with the alveoli). Function: to bring oxygen to the blood and eliminate carbon dioxide. 4) Skeletal system: the components are the bones, the cartilage, and the joints. Function: to support the body, protect the organs, and allow movement. (Present images that illustrate each of the systems.) — The circulatory system was described by William Harvey in 1628 in 'De Motu Cordis,' considered the founding milestone of modern physiology, which explained the cardiac cycle and the closed circulation of blood continuously.

5. What are anatomical variations?

   Answer: Anatomical variations are normal (non-pathological) individual differences in the shape, size, position, or number of structures, such as arteries with different paths, extra bones, or accessory muscles. — About 30% of the human population presents some significant anatomical variation according to the Atlas of Human Anatomical Variations, and its recognition is important in surgery to avoid unexpected intraoperative complications.

6. Make a glossary with the following anatomical terms:
   • Superficial and deep;
   • Medial and lateral;
   • Posterior and anterior;
   • Caudal and cranial;
   • Distal and proximal;
   • Medial;
   • Dorsal;
   • Abdomen;
   • Flexion and extension;
   • Abduction and adduction;
   • Opposition;
   • Rotation;
   • Circumduction;

   Answer: You use: superficial/deep (near/far from the skin), medial/lateral (near/far from the midline), anterior/posterior (front/back), caudal/cranial (head/feet), distal/proximal (far/near the point of attachment). — Anatomical terms follow the Terminologia Anatomica (TA) standard updated in 1998 by FIPAT (Federative International Programme on Anatomical Terminology), replacing old names with modern international standardization.

7. What does the Bible say about caring for the body? 1 Corinthians 6:19-20.

   Answer: You read: 'your body is the temple of the Holy Spirit... Glorify God in your body.' Principle: the body is a divine gift and deserves care in diet, exercise, rest, and moral purity. — 1 Corinthians 6:19-20 is the biblical basis for Adventist health, the foundation of the 8 natural remedies (NEWSTART) advocated by Ellen White since 1865 and still promoted by Loma Linda University in current studies.
