Introduction to Anatomy and Physiology. Search for:. Overview of Anatomy and Physiology. Defining Anatomy Human anatomy is the study of the structure of the human body. Learning Objectives Define the two major subtypes of anatomy. Key Takeaways Key Points Gross anatomy is subdivided into surface anatomy the external body , regional anatomy specific regions of the body , and systemic anatomy specific organ systems.
Microscopic anatomy is subdivided into cytology the study of cells and histology the study of tissues. Anatomy is closely related to physiology study of function , biochemistry chemical processes of living things , comparative anatomy similarities and differences between species , and embryology development of embryos.
Knowledge of anatomy is needed to understand human biology and medicine. Key Terms anatomy : The study of the body structure of animals. Sometimes called superficial anatomy. Gross or macroscopic anatomy : The study of anatomical features visible to the naked eye, such as internal organs and external features.
Learning Objectives Describe physiology in the context of living systems. Key Takeaways Key Points The study of physiology occurs at many levels, including organisms, organ systems, organs, cells, and biomolecules.
Physiology investigates the processes and mechanisms that allow a living thing to survive, grow, and develop. Homeostasis is the maintenance of the overall stability of physiological processes of the body. It is monitored by the brain and nervous system and regulated by the physiology and activity of individual organs. While anatomy deals with the structure of the parts of an organism, physiology studies the way that the parts function together.
Anatomy The science dealing with the form and structure of living organisms. Field of biological sciences which focuses on the description of body structures of living things. Physiology The science which relates to the function of organs and organ systems. Pathology Branch of medical sciences which involves the study and diagnosis of disease through surgical examination of organs, tissues, biopsy samples, body fluids, in certain cases the whole body autopsy.
The crural diaphragm consists of bundles of muscle fibers that arise from the first three lumbar vertebral bodies and the medial and lateral arcuate ligaments on each side.

Davis AT Collection. Methods: Consensus process over a period of 16 months, representing the opinions of 12 experts from seven countries.
Main outcome measure: Expert opinion was based on the grading of scientific and evidence-based medical literature, internal committee discussion, public presentation, and debate.
Results: ED occurs from multifaceted, complex mechanisms that can involve disruptions in neural, vascular, and hormonal signaling.
