    • Sagittal Plane: Divides the body into left and right sections (not necessarily equal).
    • Transverse Plane: Divides the body into superior and inferior sections.
  • Anatomical Position: The standard position for describing body parts.

Body Organization and Systems

  • Atomism: Atom → Molecule → Organelle → Cell → Organ → Organ System → Organism
  • Levels of Organization: Cells, tissues, organs, organ systems.
  • Human Organism → Organ System → Organs → Tissues

    • Nervous: Control, regulation, and coordination of other systems, sensation, memory.
    • Endocrine: Hormone production, control and regulation of other systems.
    • Circulatory: Circulation of oxygen, nutrients, wastes, hormones, electrolytes, immune cells, and antibodies, fluid, electrolyte, and acid-base balance.
    • Digestive: Breakdown and absorption of nutrients, elimination of wastes.
    • Reproductive (Female): Production of eggs, site of fertilization, fetal development, birth, lactation, sex hormone secretion.
    • Reproductive (Male): Production and delivery of sperm, secretion of sex hormones.

Body Planes and Organization

  • Anatomical Position: The standard reference position when describing human anatomy.
  • Regions: Head, neck, torso/trunk, upper limb, and lower limb (More detailed regions of the body can be learned later).
  • Directional terms: Superior, inferior, anterior, posterior, medial, lateral, proximal, distal, superficial, and deep.
  • Body Cavities and Quadrants: A cavity is a hollow space within the body, and the body is further divided into various regions such as quadrants. (More detailed information about body quadrants and cavities will be covered later.)

Homeostasis(Chapter 2 Part 3)

  • Homeostasis: The dynamic equilibrium of the internal environment in the body.
  • Homeostatic Regulation (Involves):
    • Receptor: Receives information about changes in the environment.
    • Control Center: Receives and processes information from the receptor.
    • Effector: Responds to signals from the control center. This response can oppose or enhance the stimulus to maintain a stable internal environment.
