Exams: Use of correct anatomical and physiological terms required.
Communication: Essential for sounding intelligent with colleagues and superiors in healthcare.
Course Structure: Anatomy and Physiology are taught together due to their interdependence; Hillsborough Community College offers Anatomy and Physiology I & II.
Anatomy vs. Physiology
Anatomy: Structure and form of body parts.
Physiology: Function and how it relates to structure.
Examples:
Wheels are round for rotation.
Sickle cell anemia: Malformed red blood cells lead to malfunction.
Types of Anatomy
Gross Anatomy: Structures visible to the naked eye.
Microscopic Anatomy: Structures requiring a microscope (e.g., histology).
Developmental Anatomy: Focuses on embryology and changes from conception to birth.
Systems Overview
Chapter Breakdown:
Chapter 1: Overview
Chapter 2: Chemistry
Chapter 3: Cells
Chapter 4: Histology (Lab-focused)
Subsequent chapters cover systems like integumentary, skeletal, muscular, and more.
Physiology Focus
Study Levels: Cellular to molecular.
Importance of Chemistry and Physics: Understanding chemical reactions and physical principles.
Complementarity Principle: Structure and function are interrelated.
Hierarchy of Organization
Chemical Level: Atoms and molecules.
Cellular Level: Organelles and cells.
Tissues, Organs, Organ Systems: Lead to the organism.
Requirement for Life: Maintaining boundaries, movement, response to stimuli, digestion, metabolism, excretion, reproduction, and growth.
Maintaining Homeostasis
Homeostasis: Balance in the body’s internal environment.
Components: Receptor, control center (brain), and effector.
Feedback Mechanisms:
Negative Feedback: Most common, maintains equilibrium (e.g., temperature, blood sugar).
Positive Feedback: Enhances original stimulus (e.g., childbirth, clotting).
System Overviews
Integumentary System: Skin, hair, nails, protection, vitamin D synthesis.
Skeletal System: Bones, joints, protection, and support.
