Study Notes
Chapter 1: Introduction to Anatomy and Physiology
- Anatomy is the study of the structure of the body, while physiology focuses on the function of those structures.
- Contralateral refers to opposite sides of the body, essential for understanding body symmetry.
- The cranial cavity houses the brain, a critical component of the central nervous system.
- The anatomic position is defined as standing forward with arms at sides and palms facing forward, providing a standard reference point.
- The apex refers to the narrowest part of a structure, important for understanding anatomical shapes.
Chapter 2: Homeostasis and Control
- Homeostasis is the body’s ability to maintain a stable internal environment, crucial for survival.
- Negative feedback mechanisms stop or reverse processes to restore equilibrium, such as temperature regulation.
- Positive feedback amplifies changes, pushing the system further away from its starting state; an example is childbirth.
- Intrinsic regulation allows cells within the same tissue to regulate each other, demonstrating cellular communication.
Chapter 3: Chemistry and Biological Molecules
- Protons are positively charged subatomic particles, while neutrons have no charge, and electrons are negatively charged.
- Isotopes are variants of elements that differ in the number of neutrons, impacting atomic mass but not chemical properties.
- Ionic bonds involve electron transfer between atoms, while covalent bonds involve sharing of electrons.
- Water (H2O) is an example of an inorganic molecule, vital for life due to unique properties such as high specific heat and solvent capabilities.
- Acids release hydrogen ions (H+) into solutions, decreasing pH, while bases, like ammonia, raise pH.
Chapter 5: Cell Structure and Organelles
- The primary component of cell membranes is phospholipids, forming a bilayer that regulates substance entry and exit.
- Cytoplasm is a gel-like substance where organelles are suspended, facilitating intracellular processes.
- The nucleus contains DNA, which codes for proteins and regulates cell activities.
- Exons are sequences that exit the nucleus to express genetic information, critical for protein synthesis.
- Ribosomes are responsible for protein synthesis, assembling amino acids into polypeptides.
Chapter 6: Cell Transport and Enzymes
- Concentration gradients dictate the movement of particles from areas of higher concentration to areas of lower concentration.
- Osmosis is the specific term for water diffusion across membranes, crucial for maintaining cell volume.
- Isotonic solutions maintain red blood cell shape, whereas hypotonic solutions cause swelling and potential bursting, while hypertonic solutions lead to cell shrinkage.
- Active transport requires ATP energy to move materials against a concentration gradient, contrasting with passive transport, which requires no energy.
Chapter 7: Protein Synthesis and Cell Cycle
- Ribosomal RNA (rRNA) is produced in the nucleolus, essential for composing ribosomes.
- Messenger RNA (mRNA) carries genetic code from DNA to ribosomes for protein synthesis.
- Transfer RNA (tRNA) delivers specific amino acids to ribosomes during translation, building proteins.
- Amino acids serve as the fundamental building blocks of proteins, essential for cellular structure and function.
- Mitosis is the phase of the cell cycle where cell division occurs, producing two identical daughter cells, vital for growth and repair.
General Concepts
- Mitosis involves several phases: prophase, metaphase (where chromosomes align), anaphase (chromosomes pulled apart), and telophase (completion of division).
- The S phase of the cell cycle is where DNA synthesis occurs, ensuring proper genetic material is allocated to daughter cells.
