      • Multiple choice questions
      • True/False questions
      • Fill in the blanks
      • Match the following
      • Illustrations/figures
      • Bonus questions
    • No 'rounding up' in this course, grades are calculated to the first decimal point
    • Letter grade system is used for final grade

    Resources

    • Enrollment key: Anatomy! “How the machinery works”

    Directional Terms

    • Use directional terms for body regions, structures, and positions

    Regional Terms

    • Use regional terms to identify specific parts of the body

    Body Planes

    • Sagittal plane: divides the body vertically into left and right sections
    • Frontal/coronal plane: divides the body vertically into anterior and posterior sections
    • Transverse/horizontal/axial plane: divides the body horizontally into superior and inferior sections
    • Oblique plane: divides the body at an angle

    Body Cavities

    • Body cavities enclose and protect delicate internal organs
    • Two largest compartments are:
      • Dorsal body cavities
      • Ventral body cavities

    Dorsal Body Cavities

    • Continuous cavity formed from:
      • Cranial cavity: encloses the brain, protected by skull bones and cerebrospinal fluid
      • Spinal/vertebral cavity: surrounds spinal cord, protected by vertebral column and cerebrospinal fluid
    • Lined by meninges filled with cerebrospinal fluid, providing protection/cushion to the brain and spinal cord

    Ventral Body Cavities

    • Larger cavity
    • Subdivided into two parts:
      • Thoracic cavity (contains lungs, heart, esophagus, trachea; protected by rib cage and vertebral column)
      • Abdominopelvic cavity (contains stomach, intestines, spleen, liver, kidneys, adrenal glands, urinary bladder, reproductive organs, and rectum)

    Other Body Cavities

    • Smaller cavities exposed to environment:
      • Oral and digestive cavities
      • Nasal cavity
      • Orbital cavities
      • Middle ear cavities
    • Not exposed to environment:
      • Synovial cavities (joint cavities)

    Abdominopelvic Regions and Quadrants

    • Abdominopelvic regions:
      • Right hypochondriac region
      • Epigastric region
      • Left hypochondriac region
      • Right lumbar region
      • Umbilical region
      • Left lumber region
      • Right Iliac (inguinal) region
      • Hypogastric region
      • Left iliac (inguinal) region

    Abdominopelvic Regions and Its Organs

    • Each region contains specific organs

    Levels of Organization

    • The human body is organized at different levels:
      • Atoms
      • Molecules
      • Cells
      • Tissues
      • Organs
      • Organ Systems
      • Organism

    Organ Systems

    • All organ systems cooperate to support basic life processes, maintain homeostasis, and ensure proper body functioning

    Basic Life Processes

    • Metabolism:
      • Catabolism: breaking down complex molecules into simpler ones
      • Anabolism: building complex molecules from simpler ones
    • Adaptability: ability to adjust to changing environmental conditions
    • Reproduction: process of creating offspring
    • Growth and Development: increase in size and complexity of the organism
    • Movement and Locomotion: ability to move and change position
    • Integument: protection, temperature regulation, sensory reception
    • Respiration: gas exchange (oxygen intake and carbon dioxide release)
    • Circulation: transport of blood, nutrients, and waste products
    • Digestion: breakdown of food and absorption of nutrients
    • Excretion: removal of waste products

    Homeostasis

    • Self-regulating mechanism within organisms that maintains relatively stable internal conditions despite environmental fluctuations
    • Essential for survival
    • Disrupted by external stimuli (intense heat, cold, lack of oxygen) and internal stimuli (psychological stresses, exercise)
    • Regulated primarily by the nervous system and endocrine system

    Homeostatic Control

    • Involves three components:
      • Sensor (monitors environmental factors and responds to changes)
      • Control center (guides the set point, receives monitoring input, guides appropriate response)
      • Effector (receives output from control center, provides instructions for response)

    Homeostasis via Neuronal Control

    • Nervous system detects changes and sends nerve impulses to counteract the disruption
    • Nerve impulses cause rapid changes

    Homeostasis via Negative Feedback Process

    • Reduces the initial imbalance or stress
    • Example: maintaining body temperature

    Homeostasis via Hormonal Control: Negative Feedback Process

    • Endocrine system regulates homeostasis by secreting hormones
    • Hormones work slowly
    • Example: regulating blood glucose levels

    Homeostasis via Positive Feedback Process

    • Intensifies the initial imbalance or stress
    • Example: childbirth
