  • Anatomy

    Study of body structures and how those structures relate to one another.

  • Physiology

    Study of how the body and its parts function.

  • Gross anatomy / macroscopic anatomy

    Study of structures large enough to be seen without a microscope.

  • Microscopic anatomy

    Study of structures that require magnification to be seen.

  • Levels of organization

    Chemical, cellular, tissue, organ, organ system, and organism levels, from simplest to most complex.

  • Organ system

    A group of organs that work together to perform major body functions.

  • Tissue

    A group of similar cells and associated materials working together.

  • Homeostasis

    Maintenance of a relatively stable internal environment.

  • Receptor in homeostatic regulation

    Sensor that detects a stimulus or change in a regulated condition.

  • Control center in homeostatic regulation

    Receives and processes information and determines the response.

  • Effector in homeostatic regulation

    Cell, tissue, or organ that carries out the response directed by the control center.

  • Negative feedback

    Response opposes the original change and moves a condition back toward its normal range.

  • Positive feedback

    Response strengthens or amplifies the original change.

  • Anatomical position

    Standing upright, facing forward, feet together, arms at sides, palms facing forward.

  • Supine

    Lying on the back, face up.

  • Prone

    Lying on the abdomen, face down.

  • Abdominopelvic quadrants

    Four clinical divisions: right upper (RUQ), left upper (LUQ), right lower (RLQ), and left lower (LLQ).

  • Thoracic cavity

    Chest cavity containing the pleural cavities and mediastinum; houses lungs, heart, and other structures.

  • Abdominal cavity

    Superior portion of the abdominopelvic cavity; contains many digestive organs.

  • Pelvic cavity

    Inferior portion of the abdominopelvic cavity; contains urinary bladder, reproductive organs, and distal digestive structures.

  • Superior

    Above; toward the head.

  • Inferior

    Below; toward the feet.

  • Anterior

    Toward the front of the body.

  • Posterior

    Toward the back of the body.

  • Medial

    Toward the body's midline.

  • Lateral

    Away from the body's midline.

  • Proximal

    Closer to the point of attachment or origin.

  • Distal

    Farther from the point of attachment or origin.

  • Frontal / coronal plane

    Divides the body into anterior and posterior portions.

  • Sagittal plane

    Divides the body into right and left portions.

  • Midsagittal section

    Sagittal section exactly along the midline, producing equal right and left halves.

  • Transverse / horizontal plane

    Divides the body into superior and inferior portions.
