Study Notes
Introduction to Anatomy & Physiology
- Chapter 1 introduces the structure and function of the human body, and how its systems 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 imaging techniques.
Anatomy
- Anatomy is the study of the body's structures.
- It includes: where structures are located, what they look like, and what they are called.
Physiology
- Physiology is the study of the body's functions.
- It examines what structures do, why they do it, and how they do 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: medical specialties
- Developmental anatomy: from conception to adulthood, including embryology
- 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 of Living Organisms
- Organization: Life is organized at various levels (chemical, cellular, tissue, organ, organ system, organism)
- Metabolism: The chemical reactions in cells that generate energy and allow growth and repair. Includes catabolism (breaking down molecules) and anabolism (building molecules).
- Responsiveness to Stimuli: The ability to respond to changes in internal and external environments (e.g., reflex actions, sensory responses).
- Movement: Includes movement within the body (e.g., blood flow, food movement through digestive system) and movement of the organism as a whole.
- Growth and Development: Organisms grow (increase in size) and develop (change in structure and function over time).
- Reproduction: The ability to produce offspring, ensuring the continuation of the species.
- Homeostasis: Maintaining a stable internal environment despite external changes.
Organization of the Body
- The body is organized hierarchically from simple to complex.
- The levels are: Chemical, Cellular, Tissue, Organ, Organ System, and Organismal.
Organ Systems
- There are 11 organ systems (R U N MRS LIDEC)
- Respiratory
- Urinary
- Nervous
- Reproductive
- Integumentary
- Muscular
- Lymphatic
- Digestive
- Endocrine
- Cardiovascular
- Skeletal
Medical Imaging Techniques
- X-Ray: Uses radiation to create images of the inside of the body; most commonly used for visualizing bones (cheap, fast, good for bones/teeth but not detailed).
- CT Scan (Computed Tomography): Combines X-ray images taken from different angles to create cross-sectional images of the body (detailed imaging, useful for soft tissues - more radiation).
- MRI (Magnetic Resonance Imaging): Uses strong magnetic fields and radio waves to generate detailed images of organs and soft tissues without radiation (expensive, uncomfortable patient experience, but great for finding tumors).
- Ultrasound: Uses high-frequency sound waves to create images of organs and tissues inside the body (non-invasive and widely used in pregnancy assessment) (image quality depends on techincian skill).
- PET Scan (Positron Emission Tomography): Uses a radioactive substance to visualize metabolic activity and functional processes inside the body (can visualize live metabolic activity).
- Endoscopy: Uses a flexible tube with a camera to visualize the inside of hollow organs (commonly used for gastrointestinal procedures).
Body Cavities
- Body cavities are spaces within the body that house and protect internal organs.
- There are dorsal (spinal, cranial) and ventral (thoracic, abdominopelvic) cavities, subdivided into smaller cavities.
- Serous membranes line these cavities and cover organs to reduce friction.
Sectional Planes
- Sectional planes are two-dimensional slices through a three-dimensional body to visualize internal organization.
- Key planes include frontal (coronal), sagittal (midsagittal, parasagittal), and transverse.
Homeostasis
- Homeostasis is the body's ability to maintain a stable internal environment (temperature, blood pressure, pH, glucose) despite external changes.
- Homeostatic mechanisms use negative and positive feedback to regulate conditions.
- Negative feedback maintains a set point, while positive feedback amplifies change.
