  • What is Human Anatomy?

    Human Anatomy is the study of the structure or form of the human body.

  • What is Human Physiology?

    Human Physiology is the study of the body's functions and how the body parts work.

  • What is the relationship between structure and function in the body?

    The body’s structure and function are closely related; the form of a structure best suits its function.

  • Name the core study strategies recommended for learning Anatomy & Physiology.

    Bring It Back, Space It Out, and Mix It Up are the three core study strategies to improve long-term retention.

  • What is the purpose of the 'Bring It Back' study strategy?

    To transfer information from short-term to long-term memory through active recall methods like self-quizzing and flashcards.

  • Define 'Metabolism' in living organisms.

    Metabolism is the sum of all chemical processes in the body, including anabolism (building up) and catabolism (breaking down).

  • List the six characteristics shared by living organisms.

    Cellular composition, metabolism, growth, excretion, responsiveness, movement, and reproduction.

  • What are the six structural levels of organization in the human body?

    Chemical, Cellular, Tissue, Organ, Organ System, and Organism levels.

  • How many organ systems are in the human body?

    There are 11 organ systems in the human body.

  • What is the anatomical position?

    The body standing upright, feet shoulder-width apart, arms at sides, palms and head facing forward; used as a reference point.

  • Define the directional terms: Anterior and Posterior.

    Anterior means toward the front; Posterior means toward the back of the body or body part.

  • What do the terms Superior and Inferior mean?

    Superior means toward the head; Inferior means toward the feet or tail end.

  • Explain the difference between Proximal and Distal.

    Proximal means closer to the point of origin; Distal means farther from the point of origin, used for limbs.

  • What are the three main planes of section in anatomy?

    Sagittal (divides left and right), Frontal/Coronal (divides front and back), and Transverse/Horizontal (divides top and bottom).

  • What is homeostasis?

    Homeostasis is the body's ability to maintain a relatively stable internal environment despite external changes.

  • Describe a negative feedback loop.

    A feedback mechanism that opposes a change in a regulated variable to restore it to normal range.

  • List the steps of a negative feedback loop.

    Stimulus, receptor, control center, effector, and response to return variable to normal.

  • What is a positive feedback loop?

    A feedback mechanism that reinforces the initial change and increases the output until an external event stops it.

  • Give an example of a positive feedback loop in the human body.

    Childbirth: uterine contractions increase until the baby is born, then the loop stops.

  • What are serous membranes and their function?

    Thin double-layered tissues that secrete serous fluid to lubricate organs in body cavities.

  • Name the two main divisions of the anterior body cavity.

    Thoracic cavity (above diaphragm) and Abdominopelvic cavity (below diaphragm).

  • What is the difference between the visceral and parietal layers of serous membranes?

    Visceral layer contacts the organ; Parietal layer attaches to surrounding structures.

  • What is the function of gradients in physiology?

    Gradients drive physiological processes by moving substances from areas of higher to lower concentration, pressure, or temperature.

  • How do cells communicate to maintain homeostasis?

    Through electrical signals and chemical messengers that coordinate body functions.
