Study Notes
Levels of Organization
- Atoms combine to form molecules, which combine to form macromolecules, and subsequently cells.
- Cells form tissues, tissues form organs, and organs form systems. This progression displays increasing complexity in biological organization.
Cell Structures
- Cell: The basic unit of structure and function in living things.
- Membrane: A lipid bilayer that surrounds cells and organelles, controlling substance entry and exit.
- Cytoplasm: Gel-like substance containing organelles.
- Organelles: Specialized structures within cells with specific functions.
- Non-membranous Organelles: Ribosomes (protein synthesis) and cytoskeleton (structural support).
- Membranous Organelles: Nucleus (genetic material & control center), mitochondria (energy production), endoplasmic reticulum (protein and lipid synthesis), and Golgi apparatus (modifying, sorting & packaging proteins/lipids).
Anatomical Terminology
- Anatomical Position: Standard reference position for human anatomy.
- Directionality: Terms like anterior/posterior, superior/inferior, to describe locations relative to each other or to the body as a whole.
- Body Regions: Specific divisions of the body (e.g., head, chest).
- Planes: Imaginary flat surfaces used to describe body sections like sagittal, coronal.
- Quadrants: Four divisions of the abdomen.
Organ Systems Summary
- The following organ systems are frequently studied to understand their complex functions and interactions:
- Integumentary
- Musculoskeletal
- Nervous
- Endocrine
- Lymphatic
- Cardiovascular
- Digestive
- Genitourinary
Key Terminology Analysis
- Root: The fundamental word part (e.g., bio-, rhin-, my-).
- Combining Vowel: Connects the root to other parts (often "o" or "i").
- Suffix: The word ending (e.g., -logy, -itis, -algia).
- Prefix: Word beginning impacting meaning (e.g., a-, ex-, dys-). Always analyze the meaning from the suffix/ending back to the start of the root.
