Study Notes
Introduction to the Human Body
- The chapter introduces anatomy and physiology.
- It discusses the organization of the human body.
- It reveals shared properties of all living things.
- It discusses homeostasis.
Anatomy vs. Physiology
- Anatomy studies the structure of body parts.
- Physiology studies how body parts function.
- Anatomy and physiology are inseparable.
- Function reflects structure.
- Structure dictates function.
Branches of Anatomy and Physiology
- Developmental biology: Studies growth and development from fertilization to death.
- Embryology: Studies development after fertilization of a human egg.
- Cell biology: Studies cellular structure and functions.
- Histology: Studies microscopic structure of tissues.
- Gross anatomy: Observable body structures without a microscope.
- Systemic anatomy: Study of specific body systems.
- Regional anatomy: Study of specific regions of the body.
- Surface (topographical) anatomy: Study of surface markings of the body.
- Imaging anatomy: Visualization of body structures with imaging techniques.
- Clinical anatomy: Application of anatomy to medical practice.
- Pathological anatomy: Structural changes related to disease.
Branches of Physiology
- Molecular physiology: Studies functions of individual molecules.
- Neurophysiology: Studies functional properties of nerve cells.
- Endocrinology: Studies hormones and how they control body functions.
- Cardiovascular physiology: Studies functions of the heart and blood vessels.
- Immunology: Studies the body's defenses against disease.
- Respiratory physiology: Studies functions of the air passageways and lungs.
- Renal physiology: Studies functions of the kidneys.
- Exercise physiology: Studies changes in cell and organ function due to activity.
- Pathophysiology: Studies functional changes associated with disease and aging.
Levels of Structural Organization
- Chemical level: Atoms combine to form molecules.
- Cellular level: Cells are the basic units of life.
- Tissue level: Tissues are groups of similar cells.
- Organ level: Organs are composed of different tissues.
- System level: Organ systems work together to perform specific functions.
- Organismal level: The human body as a whole.
Systems of the Human Body
- Integumentary system: Protects the body, regulates temperature, excretes waste, detects sensations.
- Skeletal system: Supports and protects the body, aids movement, produces blood cells, stores minerals.
- Muscular system: Enables body movement, maintains posture, produces heat.
- Nervous system: Generates nerve impulses, regulates body activities, processes information.
- Endocrine system: Regulates body activities via hormones.
- Cardiovascular system: Transports blood, oxygen, and nutrients, regulates acid-base balance, temperature, and water content.
- Lymphatic/immune system: Returns proteins and fluid to blood; fights disease, contains lymphoid tissues.
- Respiratory system: Transfers oxygen and carbon dioxide, regulates acid-base balance.
- Digestive system: Breaks down food, absorbs nutrients, and eliminates waste.
- Urinary system: Removes wastes and regulates water and electrolyte balance, maintaining blood pH.
- Reproductive system: Enables reproduction through gametes and hormones.
Basic Life Processes
- Metabolism: Sum of all chemical processes in the body.
- Responsiveness: Ability to detect and respond to changes.
- Movement: Motion of the whole body or its parts.
- Growth: Increase in body size.
- Differentiation: Development of cells from unspecialized to specialized cells.
- Reproduction: Production of new cells or organisms.
Homeostasis
- A condition of equilibrium or balance in the body's internal environment.
- Maintained by regulatory processes.
- Imbalances cause diseases, disorders, and potentially death.
Body Fluids & Homeostasis
- Body cells survive by regulating extracellular fluid composition.
- Extracellular fluid is critical for cellular function.
Control of Homeostasis
- Basic components of a feedback loop include: stimulus, receptor, control center, effector, and response.
Control of Homeostasis: Negative Feedback
- Original stimulus decrease in intensity.
- Change is opposite to original stimulus, reducing imbalances.
Examples of Negative Feedback Mechanism
- Thermoregulation: A mechanism that regulates body temperature by detecting and responding to changes in temperature.
- The Body responds to temperature changes by regulating blood flow, sweating, and shivering.
Regulation of Blood Glucose Levels
- Control of blood glucose concentration is critical for body functions, regulated by hormones like insulin and glucagon.
Control of Homeostasis: Positive Feedback
- The change amplifies the original stimulus.
- Example of positive feedback is labor.
Basic Anatomical Terminology
- Includes body positions, regional names, directional terms, planes and sections, and body cavities.
Types of Anatomical Terminology
- Body Positions: Standard, consistent way to view the body
- Regional Names: Specific body parts and regions.
- Directional Terms: Describe the positions of body structures relative to each other.
Body Positions: The Anatomical Position
- Erect, face forward, palms forward, feet flat.
- A standardized method for observing the body.
- Standardized reference for anatomical description.
Body Positions
- Prone (lying facedown)
- Supine (lying faceup)
Regional Names
- Refers to specific regions of the body for reference (e.g., cephalic, cervical, thoracic, abdominal, etc).
Directional Terms
- Terms to locate one part of the body relative to another precisely (e.g., superior, inferior, anterior, posterior, medial, lateral, proximal, distal, superficial, deep).
Planes and Sections
- Imaginary flat surfaces that divide the body (coronal, transverse, median, oblique planes).
- Cuts of the body structure to view internal structures (e.g., cross-sections, longitudinal sections).
Practicing Planes and Sections
- Example of identifying the body planes based on images given (e.g., brain sections).
Body Cavities
- Spaces within the body that protect, separate, and support internal organs (e.g., cranial cavity, vertebral canal, thoracic cavity, abdominopelvic cavity—abdominal and pelvic cavities).
Serous Membranes
- Thin, double-layered membranes lining the thoracic and abdominal cavities, reducing friction.
- Include the visceral and parietal layers, covering organs and cavity walls.
- Examples include pericardium, pleura, and peritoneum.
Serous Membranes in the Thoracic Cavity
- Pericardium for the heart and pleura for the lungs, lining the pleural and pericardial cavities.
- Cover the heart and lungs in the thoracic cavity.
Serous Membrane in the Abdominal Cavity
- The peritoneum covers many abdominal organs.
- Retroperitoneal organs lie behind the peritoneum.
Abdominopelvic Regions & Quadrants
- The abdomen and pelvis are divided into regions and quadrants for organ description purposes (the quadrants being right upper, right lower, left upper, and left lower).
Aging and Homeostasis
- Aging involves a decline in the body's ability to restore homeostasis.
- This decline impacts various systems, potentially leading to issues or diseases, such as declining organ function.
