  • What is an organ?
    An organ is a structure composed of two or more tissue types that work together to perform specific functions.
  • Define an organ system.
    An organ system is a group of organs that work together to perform complex functions for the body.
  • What is regional anatomy?
    Regional anatomy studies the organization of the body by specific areas or regions, such as the head, chest, or limbs.
  • What are directional terms in anatomy?
    Directional terms describe the location of structures relative to other structures, e.g., anterior, posterior, medial, and lateral.
  • Name the major body cavities.
    The major body cavities are the cranial, vertebral, thoracic, and abdominopelvic cavities.
  • What are planes/sections in anatomy?
    Planes are imaginary flat surfaces used to divide the body, including the sagittal, frontal (coronal), and transverse planes.
  • How are abdominal regions divided?
    The abdomen is divided into nine regions to localize organs, including the epigastric, umbilical, and hypogastric regions.
  • What are serous membranes?
    Serous membranes are thin layers that line body cavities and cover organs, producing serous fluid to reduce friction.
  • Name key cell organelles and their functions.
    Nucleus: controls cell activities; mitochondria: produce energy; ribosomes: synthesize proteins; endoplasmic reticulum: processes proteins and lipids.
  • What is diffusion?
    Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration.
  • Compare passive and active transport.
    Passive transport requires no energy and moves substances down their concentration gradient; active transport requires energy to move substances against their gradient.
  • What is resting membrane potential?
    Resting membrane potential is the electrical charge difference across the cell membrane when the cell is at rest, typically around -70 mV.
  • Define tonicity.
    Tonicity describes the ability of a solution to affect the volume of a cell by osmosis, such as isotonic, hypertonic, and hypotonic solutions.
  • What are the main types of connective tissue?
    Connective tissue types include loose, dense, cartilage, bone, and blood.
  • What fiber types are found in connective tissue?
    Connective tissue fibers include collagen (strength), elastic (stretch), and reticular (support).
  • How are tissues identified?
    Tissues are identified by their cell types, fiber types, and location in the body.
  • What is the function of connective tissue?
    Connective tissue supports, binds, protects organs, stores energy, and transports substances within the body.
