    Study Notes

    Chapter 1: Introduction to Anatomy & Physiology

    • The chapter introduces the structure and function of the human body, explaining how the body's systems are organized and work together.
    • Key topics include levels of structural organization, human body systems, characteristics of living organisms, requirements for life, homeostasis, anatomical terminology, body cavities and organ protection, and imaging techniques.

    Anatomy & Physiology

    • Anatomy is the study of the body's structures (where it is, what it looks like, what it is called).
    • Physiology is the study of the body's functions (what it does, why it does it, how it does it).
    • Structure dictates function.

    Approaches to Studying Anatomy

    • Gross anatomy (macroscopic anatomy): Examines large, visible structures
      • Surface anatomy: studies exterior features and markings
      • Regional anatomy: examines body areas
      • Sectional anatomy: examines cross sections
      • Systemic anatomy: focuses on individual organ systems
    • Clinical anatomy: focuses on medical specialties
    • Developmental anatomy: studies from conception to adulthood, including embryology

    Gross and Microscopic Anatomy

    • Gross anatomy examines large structures like the brain.
    • Microscopic anatomy examines structures at a smaller scale like nerve cells, using a microscope.

    Approaches to Studying Anatomy Cont'd

    • Microscopic anatomy: examines cells and molecules using a microscope
      • Cytology: study of cells
      • Histology: study of tissues

    Approaches to Studying Physiology

    • Cell physiology: functions of organelles and cells.
    • Organ physiology: functions of specific organs.
    • Systemic physiology: functions of organ systems.
    • Pathological physiology: effects of diseases on organs or systems.

    Characteristics/Functions of Living Organisms

    • Organization: Life is organized at various levels (chemical, cellular, tissue, organ, organ system, organism).
    • Metabolism: Chemical reactions within cells generate energy and allow growth and repair. This includes catabolism (breaking down complex molecules) and anabolism (building complex molecules from simpler ones).
    • Responsiveness to Stimuli: The ability to respond to changes in the internal and external environment (e.g., reflex actions, sensory responses).
    • Movement: Includes movement within the body (e.g., blood flow, food movement) and movement of the organism as a whole.
    • Growth and Development: Organisms grow (increase in size) and develop (change in structure and function).
    • Reproduction: The ability to produce offspring, ensuring the continuation of the species.
    • Homeostasis: The maintenance of a stable internal environment despite external changes.

    1. Organization

    • Chemical Level: Atoms and molecules (e.g., water, proteins, DNA).
    • Cellular Level: Cells are the basic units of life, with different types performing specific functions.
    • Tissue Level: Tissues are groups of similar cells working together to perform a specific function.
    • Organ Level: Organs are made of different types of tissues working together to perform specific functions.
    • Organ System Level: Organ systems are groups of organs working together to accomplish a common goal.
    • Organismal Level: The entire human body functions as a whole.

    Organ Systems

    • There are 11 organ systems.
    • A memory device for learning their names is RUN MRS LIDEC (Respiratory, Urinary, Nervous; Reproductive, Muscular, Lymphatic, Integumentary, Digestive, Endocrine, Cardiovascular).

    Medical Imaging Techniques

    • X-Ray: Uses radiation to create images of the inside of the body. Good for bones.
    • CT Scan: Combines X-rays to create detailed cross-sectional images of soft tissues, organs, and blood vessels. More radiation than X-rays.
    • MRI: Uses magnetic fields, radio waves, and no ionizing radiation to generate detailed images of organs and soft tissues. More expensive and uncomfortable.
    • Ultrasound: Uses high-frequency sound waves to create images, non-invasive, no radiation.
    • PET Scan: Uses radioactive substances to visualize metabolic activity and functional processes.

    Body Cavities and Serous Membranes

    • Chambers in the body called cavities.
    • These cavities provide cushioning, stabilize organs, and protect from friction/infection.
    • Serous membranes line the cavities and cover organs.
    • Parietal layer lines the cavity, visceral layer on the organs.
    • Serous fluid between layers reduces friction.
    • Major cavities: Dorsal (cranial and spinal) and Ventral (thoracic and abdominopelvic).

    Dividing the Abdomen

    • Quadrants and regions are ways to subdivide the abdominal region for precise description.
    • Quadrants are divided by vertical and horizontal lines through the umbilicus.
    • Regions are divided by two vertical and two horizontal lines.

    Sectional Planes

    • A section is a slice through a 3D object, showing the internal structure.
    • The plane used depends on the direction of the slice/section.
    • Frontal (coronal): Divides into anterior and posterior portions.
    • Sagittal: Divides into right and left portions.
    • - Midsagittal: Lies in the middle, equal halves
      • Parasagittal: Offset from midline
    • Transverse (cross-sectional): Divides into superior and inferior portions.

    Homeostasis

    • Homeostasis is the process of maintaining a relatively constant set of conditions (such as blood pressure, temperature, oxygen levels, blood glucose).
    • It is essential for the survival of cells and the overall functioning of the organism.
    • Homeostatic mechanisms help restrict fluctuations of internal conditions.
    • They have three parts: receptor, control center, effector.
    • Negative feedback is the most common type of homeostatic regulation and brings the body back toward a set point.
    • Positive feedback reinforces a change until a particular outcome is reached, and is used less often.

    Growth & Development

    • Growth is the increase in body size.
    • Development is the change in body structure and function.

    Reproduction

    • Reproduction is the formation of a new organism from parent organisms.
    • In humans, reproduction happens through the male and female reproductive systems.
