8. Define anatomical position. 9. What are the factors required for maintenance of life. 10. Enlist the organs of thoracic & abdominopelvic cavity. 11. Enlist the organ of cranial & spinal cavity.

Answer

Question 8: Anatomical position is the standard reference point for all medical and anatomical descriptions. It is defined as a person standing erect, facing forward, with the feet flat on the floor and slightly apart, arms hanging at the sides, and palms of the hands facing forward with the thumbs pointing away from the body. Question 9: The factors required for the maintenance of life include: Water (essential for metabolic processes and transport), Food (provides nutrients for energy and raw materials), Oxygen (releases energy from nutrients), Heat (governs the rate of chemical reactions), and Pressure (atmospheric pressure for breathing and hydrostatic pressure for blood circulation). Question 10: The Thoracic cavity contains the heart, lungs, esophagus, trachea, and thymus gland. The Abdominopelvic cavity can be divided into the Abdominal cavity (containing the stomach, liver, spleen, gallbladder, kidneys, and most of the small and large intestines) and the Pelvic cavity (containing the urinary bladder, reproductive organs, and the rectum). Question 11: The Cranial cavity houses the brain. The Spinal cavity (also known as the vertebral canal) contains the spinal cord.
