Chapter 1: The Science of Anatomy & Physiology

Part 1: Introduction to A&P Terminology

• Overview of Terminology: Key components used in Anatomy and Physiology include terminology relating to subspecialties, organ systems, regional and directional terms, planes/sections, and body cavities.

• A&P Subspecialties: Different areas of study within anatomy and physiology that provide specialized understanding and insights concerning the structure and function of the human body.

• Organ Systems: Include a detailed overview of organ systems' functions and interactions, emphasizing their roles in maintenance of life.

• Regional and Directional Terms: Essential for understanding anatomical positions and relationships; terms such as superior, inferior, medial, lateral, proximal, and distal are critical.

• Planes/Sections: Different anatomical planes (sagittal, coronal, and transverse) help in visualizing and separating anatomical structures for better study and examination.

• Body Cavities: Understanding of various body cavities (i.e., thoracic and abdominopelvic) that house different organs, with emphasis on their significance in A&P.

Part 2: Introduction to A&P Concepts

• Homeostasis: The body's ability to maintain stable internal conditions despite external changes.

• Feedback Loops: Mechanisms (positive and negative feedback) that regulate physiological processes.

  • Homeostatic Imbalances: Situations that disrupt homeostasis leading to disease states; understanding epidemiology and herd immunity is essential.

• Diagnosis of Disease: Methods and tests used to differentiate between diseases, illustrating the importance of clinical skills in identifying symptoms and signs.

• Medical Imaging Techniques: Various imaging modalities (e.g., X-rays, MRIs) used to visualize internal structures and assess function.

Part 1: Introduction to A&P & Terminology

• Anatomy vs Physiology: Understanding the difference—anatomy focuses on structure while physiology focuses on function.

• Levels of Organization: Discusses cellular, tissue, organ, organ system, and organismal levels, emphasizing their hierarchical nature.

• Abdominopelvic Quadrants/Regions: Importance of these divisions in clinical assessments.

Subspecialties of Anatomy and Physiology

• Anatomy Subspecialties:

  • Embryology: Study during early development.

  • Histology: Microscopic study of tissues.

  • Gross Anatomy: Structures visible without a microscope.

  • Pathological Anatomy: Structural changes associated with disease.

• Physiology Subspecialties:

  • Includes Neurophysiology, Endocrinology, Cardiovascular Physiology, outlining each field's focus.

Comparing Anatomy & Physiology

• Example Comparisons of Different Organs: Analyzing anatomical structure and physiological function of organs such as the thigh muscles, small intestine, esophagus, and blood capillaries, highlighting the relationship between structure and function.

Levels of Structural Organization

• Chemical Level: Atoms combine to form molecules important in biological processes (e.g., DNA).

• Cellular Level: Organelles work together to maintain functions of the cell.

• Tissue Level: Epithelial and connective tissues structure and function in the body.

• Organ Level: Different organs (e.g., liver, stomach) working together.

• Organ System Level: Cooperation of organ systems enhancing body operations.

Organ Systems Overview

• Eleven Organ Systems: Details the roles and components of each system including Integumentary, Skeletal, Muscular, Nervous, Endocrine, Cardiovascular, Lymphoid, Respiratory, Digestive, Urinary, and Reproductive systems.

Organ System Interrelationships

• System Interplay: Describes how systems interact; for example, how the integumentary system protects, the digestive and respiratory systems intake essential nutrients, and how urinary and respiratory systems eliminate metabolic wastes.

Basic Anatomical Terminology

• Anatomical Position: Establishes standard reference for anatomical descriptions.

• Directional Terms: Important for effective communication in anatomy; terms such as superior, inferior, medial, lateral, proximal, and distal define relationships and locations of body parts.

Common Regional Names

• List of Common Regions: Outlines specific names for regions including nasals, cervical, deltoid, and brachial areas, with anatomical relevance.

Major Directional Terms

• Defines directional language that is foundational in A&P including superior, inferior, dorsal, anterior, medial, and lateral.

Planes & Sections

• Clarifies different planes (sagittal, coronal, transverse) and their uses in anatomical studies.

Body Cavities

• Dorsal Body Cavity: Describes cranial and vertebral cavities.

• Ventral Body Cavity: Includes thoracic and abdominopelvic cavities, along with the roles of serous membranes.

Abdominopelvic Regions & Quadrants

• Region & Quadrant Divisions: Provides mechanisms for regional anatomy studies relevant for clinical practice.

Homeostasis & Feedback Loops

• Definitions and Mechanisms: Deep dive into homeostasis, feedback loops, and their implications on health.

• Positive vs Negative Feedback: Review of mechanisms with examples such as childbirth, blood glucose, and infection responses.

Clinical Skills and Diagnosis of Disease

• Observation Techniques: Introduces various methods like palpation, auscultation, percussion, and their roles in diagnostics.

• Critical Thinking Skills: Emphasizes the importance of critical thinking in applying A&P knowledge effectively.
