    Study Notes

    Anatomy

    • The study of the structure of the human body
    • Closely related to physiology, the study of the function of the human body

    Divisions of Anatomy

    • Gross Anatomy: Study of structures visible to the naked eye (e.g., muscles, bones, organs)
    • Microscopic Anatomy: Study of structures requiring a microscope (e.g., cells, tissues)
      • Cytology: Study of cells
      • Histology: Study of tissues

    Ways to Study Anatomy

    • Regional Anatomy: Examining one region of the body at a time, focusing on all its components
    • Systemic Anatomy: Examining one body system at a time (the approach used in this course)

    Anatomical Organization

    • Hierarchy of Organization:
      • Cells: The basic unit of life
      • Tissues: Groups of similar cells working together
      • Organs: Structures composed of different tissues, performing a specific function
      • Organ Systems: Groups of organs working together to perform a particular function
      • Organism: A complete living being composed of multiple organ systems

    Organ Systems

    • Integumentary System: Skin, hair, nails - protection, temperature regulation
    • Skeletal System: Bones, cartilage, ligaments - support, movement, protection
    • Muscular System: Muscles - movement, heat production
    • Nervous System: Brain, spinal cord, nerves - communication, control
    • Endocrine System: Glands (e.g., pituitary, thyroid, pancreas) - hormone production
    • Cardiovascular System: Heart, blood vessels - transport of blood, nutrients, oxygen
    • Lymphatic System: Lymphatic vessels, lymph nodes, spleen - fluid balance, immunity
    • Respiratory System: Lungs, trachea, bronchi - gas exchange
    • Digestive System: Mouth, esophagus, stomach, intestines - digestion and absorption
    • Urinary System: Kidneys, bladder, ureters - waste removal, fluid balance
    • Reproductive System: Male and female reproductive organs - reproduction

    Anatomical Directions

    • Four-footed body directions:
      • Anterior: Front
      • Posterior: Behind
      • Dorsal: Back
      • Ventral: Belly

    Planes and Sections

    • Sagittal Section: Divides the body into right and left sides
      • Mid-sagittal Section: Divides the body straight down the center
    • Frontal Section: Divides the body into front and back sides
    • Transverse Section (Cross Section): Divides the body straight across

    Body Cavities

    • Dorsal Cavity: Houses the brain and spinal cord
      • Cranial Cavity: Contains the brain
      • Vertebral Cavity: Contains the spinal cord
    • Ventral Cavity: Houses organs of the chest and abdomen
      • Thoracic Cavity: Houses the heart and lungs
      • Abdominopelvic Cavity: Houses digestive, reproductive, and urinary organs
        • Abdominal Cavity: Upper portion containing digestive organs
        • Pelvic Cavity: Lower portion containing reproductive and urinary organs

    Body Quadrants

    • Right Upper Quadrant (RUQ)
    • Left Upper Quadrant (LUQ)
    • Right Lower Quadrant (RLQ)
    • Left Lower Quadrant (LLQ)

    Anatomy

    • Anatomy: The study of the structure of the human body
    • Physiology: The study of the function of the human body
    • Anatomy and Physiology are closely related

    Divisions of Anatomy

    • Gross Anatomy: The study of structures visible to the naked eye, like muscles, bones, and organs
    • Microscopic Anatomy: The study of structures too small to be seen without a microscope
      • Cytology: The study of cells
      • Histology: The study of tissues

    Ways to Study Anatomy

    • Regional Anatomy: Focuses on studying one region of the body at a time, examining all its structures
    • Systemic Anatomy: Studies one body system at a time, like the skeletal or muscular systems

    Anatomical Organization

    • Cells: The fundamental units of life, forming tissues
    • Tissues: Groups of similar cells working together, forming organs
    • Organs: Structures composed of different tissues, performing specific functions
    • Organ Systems: Groups of organs working together, like the digestive or circulatory
    • Organism: A complete living being composed of all the organ systems

    Organ Systems

    • Integumentary System: Skin, hair, nails, responsible for protection and temperature regulation
    • Skeletal System: Bones, cartilage, ligaments, providing support, protection, and movement
    • Muscular System: Muscles, responsible for movement, posture, and heat production
    • Nervous System: Brain, spinal cord, nerves, responsible for communication, control, and coordination
    • Endocrine System: Glands that secrete hormones, regulating growth, metabolism, and mood
    • Cardiovascular System: Heart, blood vessels, responsible for transporting blood and oxygen
    • Lymphatic System: Lymph vessels, lymph nodes, responsible for immune function and fluid balance
    • Respiratory System: Lungs, trachea, bronchi, responsible for gas exchange (oxygen intake and carbon dioxide removal)
    • Digestive System: Mouth, stomach, intestines, responsible for breaking down food and absorbing nutrients
    • Urinary System: Kidneys, ureters, bladder, urethra, responsible for filtering blood and producing urine
    • Reproductive System: Male: testes, prostate, penis; Female: ovaries, uterus, vagina, responsible for sexual reproduction

    Body Directions - Four-Footed

    • Anterior/Ventral: Towards the front
    • Posterior/Dorsal: Towards the back
    • Superior/Cranial: Towards the head
    • Inferior/Caudal: Towards the tail

    Planes and Sections

    • Sagittal Section: Divides the body into right and left halves
      • Mid-Sagittal Section: Divides the body exactly in the middle, creating equal right and left sides
    • Frontal Section (Coronal): Divides the body into front (anterior) and back (posterior) sections
    • Transverse Section (Cross): Divides the body into upper (superior) and lower (inferior) sections

    Body Cavities
