Human Anatomy

Human anatomy is the science that deals with the physical morphology and structure of the human body. 

  • Human anatomy is further divided into two groups; gross anatomy and microscopic anatomy. Gross anatomy involves study related to anatomical structures that can be seen with unaided eyes, while microscopic anatomy is the study of minute anatomical structures, histology, and cytology.
  • Humans belong to the Subphylum Vertebrate of the Phylum Chordata as they have the characteristic internal skeleton with a backbone of vertebrae.
  • Other typical mammalian structures in humans include hair, mammary glands, and highly developed sense organs.
  • Besides, among mammals, humans have a predominantly two-legged (bipedal) posture, along with a highly developed intellectual.
  • The chemical composition of the human body is composed of water and organic compounds like proteins, carbohydrates, and lipids.
  • The human body is composed of specialized systems for different purposes; the digestive system for digestion, the respiratory system for respiration, the reproductive system for reproduction, and the skeletal and muscular system for movement.
  • Cells are the fundamental units of the human body consisting of trillions of cells in the body. The cells together form tissues.
  • Four basic types of tissues are found in humans, each of which is specialized for a particular purpose; epithelial tissue for covering the body, muscular tissue for movement, nerve tissues for signaling, and connective tissue for transport of nutrients.
  • The following organization of the human body is organs. An organ is composed of a group of specialized tissues from a structural and functional unit.
  • Organs are followed by the system as the final organization of the human body. The body includes nine major organ systems, each composed of various organs and tissues that work together as a functional unit.
  • Information on human anatomy is essential during the analysis of signs of symptoms of different diseases and disease diagnoses.
  • It also allows an understanding of the relationship between different organ systems and the changes occurring in the body’s anatomy during growth.
