  • What is anatomy?

    Anatomy is the study of the structure and shape of the body and its parts.

  • What is physiology?

    Physiology is the study of how the body and its parts function.

  • How are anatomy and physiology related?

    They are closely related because the structure of a body part often determines its function.

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

    Chemical, cellular, tissue, organ, organ system, and organism levels.

  • What is the chemical level of organization?

    The simplest level, involving atoms and molecules that form the building blocks of matter.

  • What defines the cellular level?

    Cells are the smallest living units in the body, each with specific functions.

  • What is a tissue in anatomy?

    A group of similar cells working together to perform a specific function.

  • What is an organ?

    A structure composed of at least two different tissue types that performs a specific function.

  • What is an organ system?

    A group of organs that work together to perform complex functions for the body.

  • What is the organism level?

    The highest level of organization, representing the entire living individual.

  • Why is homeostasis important in physiology?

    Homeostasis maintains a stable internal environment necessary for proper body function.

  • What is the difference between gross anatomy and microscopic anatomy?

    Gross anatomy studies structures visible to the naked eye; microscopic anatomy studies structures seen only with a microscope.

  • Name the four main types of tissues in the human body.

    Epithelial, connective, muscle, and nervous tissues.

  • What is the primary function of epithelial tissue?

    To cover body surfaces and line body cavities.

  • What role does connective tissue play?

    It supports, protects, and binds other tissues together.

  • What is the function of muscle tissue?

    To produce movement through contraction.

  • What is the function of nervous tissue?

    To transmit electrical signals for communication within the body.

  • What is the anatomical position?

    The standard reference position where the body stands upright, facing forward, arms at sides, palms forward.

  • Why is the anatomical position important?

    It provides a consistent frame of reference for describing body parts and positions.

  • What are the main body planes used in anatomy?

    Sagittal, frontal (coronal), and transverse planes.
