    Study Notes

    Anatomy and Physiology

    • Knowledge of anatomy and physiology is crucial for healthcare providers, especially for EMS personnel.
    • Anatomy focuses on the structure and makeup of the organism, divided into gross anatomy (study of organs and their location) and microscopic anatomy (study of tissues and cellular components).
    • Physiology studies the processes and functions of the body.
    • Homeostasis is the state of balance in which organs and systems function effectively. Maintaining homeostasis is essential for normal life processes.
    • Pathophysiology studies the functioning of an organism in the presence of disease.
    • Disease may result when the body cannot maintain homeostasis.

    Body Systems

    • Skeletal System: composed of 206 bones, providing support, movement, and protection.
    • Muscular System: composed of fibers that contract, causing movement. Three types of muscle: skeletal (striated), smooth, and cardiac.
    • Circulatory System: consists of the heart, blood vessels, and blood.
    • Lymphatic System: passive circulatory system that transports lymph, a plasma-like fluid that bathes the tissues.
    • Immune System: integral to the lymphatic system, defends against foreign substances and pathogens.
    • Respiratory System: includes organs and structures involved in breathing, gas exchange, and air intake.
    • Nervous System: complex network of structures that control voluntary and involuntary body activities.
    • Gastrointestinal System: composed of structures and organs involved in food intake, digestion, and elimination.
    • Urinary System: removes waste products from the blood through filtration, producing urine.
    • Reproductive System: includes structures responsible for sexual reproduction in males and females.
    • Endocrine System: consists of glands that secrete hormones to regulate body functions.
    • Integumentary System: includes skin, nails, hair, and sweat and oil glands.

    Anatomical Terminology

    • Topographic Anatomy: refers to the surface landmarks of the body.
    • Anatomic Position: patient stands facing the observer, arms by their side, palms forward.
    • Directional Terms: refer to the patient's left or right, not the observer's.
    • Anatomic Planes: imaginary lines that divide the body:
      • Frontal (Coronal) Plane: divides the body into anterior and posterior sections.
      • Transverse (Axial) Plane: divides the body horizontally.
      • Sagittal (Lateral) Plane: divides the body vertically into right and left sections.
      • Midsagittal Plane (Midline): divides the body into equal left and right halves.
    • Directional Terms: describe relative positions of body parts:
      • Superior: closer to the head.
      • Inferior: closer to the feet.
      • Medial: situated toward the midline.
      • Lateral: situated away from the midline.
      • Proximal: nearer to the trunk.
      • Distal: farther from the trunk.
      • Anterior (Ventral): belly or front side.
      • Posterior (Dorsal): spinal side or back.
    • Abdominal Quadrants: two lines intersecting at the umbilicus, dividing the abdomen into four quadrants: right upper, left upper, right lower, and left lower.

    Body Movements

    • Range of Motion (ROM): full distance a joint can be moved.
    • Flexion: moving a distal point of an extremity closer to the trunk.
    • Extension: returning a body part from a flexed position to the anatomic position.
    • Hyperflexion: exceeding the normal range of motion in flexion.
    • Hyperextension: exceeding the normal range of motion in extension.
    • Internal Rotation: turning an extremity medially.
    • External Rotation: turning an extremity away from the midline.
    • Abduction: moving an extremity away from the midline.
    • Adduction: moving an extremity toward the midline.

    Recumbent Positions

    • Supine: lying face up.
    • Prone: lying face down.
    • Trendelenburg: supine with the head lower than the feet.
    • Fowler: sitting up with knees bent or straight.
    • Semi-Fowler: sitting up with the upper body slightly leaning back.
    • Recovery Position (Left Lateral Recumbent): helps maintain an airway in an unresponsive patient.

    Basic Chemistry for Anatomy and Physiology

    • Matter: anything that takes up space and has mass.
    • Mass: physical property that determines an object's weight.
    • Elements: fundamental substances that compose matter.
    • Atoms: tiny particles that compose elements.
      • Protons: positive charge.
      • Neutrons: neutral charge.
      • Electrons: negative charge.
    • Atomic Number: number of protons in an atom.
    • Atomic Weight: number of protons and neutrons in an atom.
    • Isotopes: atoms of the same element with different numbers of neutrons.
    • Radioactivity: emission of energetic particles due to instability of atomic nuclei.
    • Molecule: chemical structure consisting of atoms held together by covalent bonds.
    • Ions: atoms that gain or lose electrons, carrying an electrical charge.
    • Ionic Bonds: form between ions with opposite charges.
    • Covalent Bonds: form when atoms share electrons.
    • Hydrogen Bonds: weak bonds between polar molecules.

    Compounds

    • Compounds: molecules made up of different bonded atoms.
    • Water: formed by two hydrogen atoms and one oxygen atom.
