Study Notes
Glossary of Physiological Terms and Principles
- Atoms are the fundamental building blocks of matter, composed of even smaller particles.
- Molecules are groups of two or more atoms, forming the smallest identifiable units of a pure substance while retaining the substance's chemical properties.
- Macromolecules are large molecules crucial for biological processes, such as proteins and nucleic acids, composed of thousands of covalently bonded atoms.
- Organelles are subcellular structures with specific roles within cells.
- Cells are the fundamental, basic units of life, responsible for all life processes, and are the structural, functional, and biological units of all living things. Cells can replicate independently.
- Tissues are groups of cells sharing a common structure and function. The word "tissue" originates from the French word for "to weave."
- Organs are collections of tissues forming functional units performing specific tasks or functions.
- Organ systems are groups of organs working together for complex functions, such as pumping blood or processing nutrients.
- Organisms are living things with organized structures, capable of reacting to stimuli, reproducing, growing, adapting, and maintaining homeostasis. Organisms include animals, plants, fungi, protists, bacteria, and archaea.
Anatomical Terms
- Anatomy is the study of an organism's structure and the relationships among its parts. It relies on techniques such as cutting/dissecting to explore structures.
- Surface anatomy focuses on anatomical landmarks visible on the body's surface.
- Radiographic anatomy studies structures visible using X-rays.
- Pathological anatomy examines structural changes associated with diseases.
Physiology Definitions
- Physiology is the scientific study of how body parts function.
- Neurophysiology is the study of nerve cells and their functional properties.
- Endocrinology is the study of hormones and how they regulate body functions.
Specific Physiological Studies
- Embryology is the study of the formation and development of an embryo and a fetus.
- Histology is the study of microscopic structures in tissues.
- Cardiovascular physiology examines the function of the heart and blood vessels.
- Immunology is the study of the body's defense mechanisms against diseases.
- Respiratory physiology studies the functioning of the air passages and lungs.
- Renal physiology investigates kidney function.
- Pathophysiology analyzes functional changes associated with diseases and aging processes.
Body Systems
- Integumentary System: The outermost layer of the body, encompassing skin and associated structures, functioning as a barrier.
- Skeletal System: The body's framework made of bones and connective tissues, offering protection and support.
- Muscular System: Consisting of skeletal, smooth, and cardiac muscles, enabling movement and other functions.
- Nervous System: A complex system coordinating actions and sensory information through signal transmission throughout the body.
- Cardiovascular System: Composed of the heart and blood vessels, responsible for circulating blood and delivering oxygen and nutrients.
- Lymphatic System: A network of vessels, nodes, and ducts, functioning in fluid balance and immune responses.
- Respiratory System: Encompassing organs facilitating breathing, including the airways and lungs.
- Digestive System: A series of organs processing food and converting it into usable nutrients for the body.
- Urinary System: Consisting of organs filtering blood and eliminating waste in the form of urine.
- Reproductive Systems: Involved in producing offspring.
Body Cavities
- Body cavities are fluid-filled spaces within the body housing and protecting internal organs.
- Thoracic cavity: The chest cavity housing the heart and lungs.
- Cranial cavity: The skull cavity containing the brain.
- Ventral cavity: The front cavity of the human body, divided into abdominal and pelvic cavities.
- Abdominopelvic cavity: Combining the abdominal and pelvic cavities.
Membrane Layers
- Parietal layer: A membrane lining the walls of a body cavity.
- Visceral layer: A membrane covering the organs within a body cavity.
