  • What is anatomy?

    Anatomy is the study of the structure of body parts and their relationships to one another.

  • What is physiology?

    Physiology is the study of the function of the body and how body parts work to carry out life-sustaining activities.

  • What principle explains the relationship between anatomy and physiology?

    The principle of complementarity of structure and function states that function always reflects structure, meaning what a structure can do depends on its specific form.

  • List the levels of structural organization in the human body from simplest to most complex.

    Chemical, Cellular, Tissue, Organ, Organ system, Organismal levels.

  • What are the two main subdivisions of anatomy?

    Gross (macroscopic) anatomy studies large body structures visible to the naked eye, and microscopic anatomy deals with structures too small to be seen without a microscope.

  • What are the three common body planes used in anatomical study?

    Sagittal (divides body into right and left), frontal (coronal) (divides body into front and back), and transverse (horizontal) (divides body into top and bottom).

  • Define homeostasis.

    Homeostasis is the maintenance of relatively stable internal conditions despite continuous changes in the environment.

  • What are the three components of a homeostatic control system?

    Receptor (monitors environment), control center (determines set point and response), and effector (carries out response).

  • What is negative feedback in homeostasis?

    A mechanism where the response reduces or shuts off the original stimulus, bringing the variable back to its set point.

  • Give two examples of negative feedback mechanisms.

    Regulation of body temperature and regulation of blood glucose by insulin.

  • What is positive feedback?

    A response that enhances or exaggerates the original stimulus, often producing a cascade effect, usually controlling infrequent events.

  • Give two examples of positive feedback mechanisms.

    Enhancement of labor contractions by oxytocin and platelet plug formation during blood clotting.

  • What are the 11 major organ systems of the human body?

    Integumentary, Skeletal, Muscular, Nervous, Endocrine, Cardiovascular, Lymphatic, Respiratory, Digestive, Urinary, Reproductive.

  • What is the anatomical position?

    Body erect, feet slightly apart, palms facing forward with thumbs pointing away from the body; used as a standard reference point.

  • Define the directional term 'superior'.

    Toward the head end or upper part of a structure; above.

  • Define the directional term 'inferior'.

    Away from the head end or toward the lower part of a structure; below.

  • What does 'medial' mean in anatomical terms?

    Toward or at the midline of the body; on the inner side of.

  • What does 'lateral' mean in anatomical terms?

    Away from the midline of the body; on the outer side of.

  • What is the difference between 'proximal' and 'distal'?

    Proximal means closer to the origin of a body part or point of attachment; distal means farther from the origin or point of attachment.

  • What are the two main body cavities?

    Dorsal body cavity (cranial and vertebral cavities) and ventral body cavity (thoracic and abdominopelvic cavities).

  • What is the function of serous membranes?

    Thin, double-layered membranes that cover surfaces in the ventral body cavity and secrete lubricating serous fluid to reduce friction.

  • Name the four abdominopelvic quadrants.

    Right upper quadrant (RUQ), Left upper quadrant (LUQ), Right lower quadrant (RLQ), Left lower quadrant (LLQ).

  • What is the importance of anatomical terminology?

    It allows precise and consistent communication about body parts and positions, reducing errors and misunderstandings in healthcare and science.
