| Question | Answer |
|---|---|
| Why is it possible to safely drink a solution that contains a 50-50 mixture of equal concentrations of a strong acid and a strong base, either of which, if ingested separately, would be very caustic and damaging? | Salt and water are formed when a strong acid and base are mixed. |
| True or false: DNA transcription is another word for DNA replication? | False |

| Generally speaking, connective tissues are largely non-living extracellular matrix. Which of the following is an EXCEPTION? | Adipose |
| True or false: salivary glands exhibit simple tubuloalveolar glandular arrangement? | False |
| Chondroblasts ________. | Within the cartilage divide and secrete new matrix |
| Which of the following is NOT a step in tissue repair? | Formation of new stem cells |
| Which of the following statements is the most correct regarding homeostatic imbalance? | It is considered the cause of most diseases. |
| Which of the following is a principle of the fluid mosaic model of cell membrane structure? | Phospholipids form a bilayer that is largely impermeable to water-soluble molecules. |
| The fingers are _____ to the wrist. | Distal |
| The upper arm is _____ to the forearm. | Proximal |
| The stomach is _____ to the spine. | Anterior |
| The lungs are _____ to the heart. | Lateral |
| The bridge of the nose is _____ to the left eye. | Medial |
| Mitochondria ________. | Contain some of the DNA and RNA code necessary for their own function |
| A transport protein allows sodium ions to diffuse to their concentration gradient. The ions move through the transport protein into the cell. The proteins use the kinetic energy of sodium ions to bring glucose into the cells. What's the transport protein? | A symporter |
| True or false: intercalated discs and striations are both characteristic of skeletal muscle? | False |
| Smooth muscle has ______ regenerative ability. | Moderate |
| Skeletal muscle has ________ regenerative ability. | Weak |
| Cardiac muscle has ________ regenerative ability. | Virtually no functional |

| Tendons and ligaments have ________ regenerative ability. | Moderate |
| Which of the following organs or structures would be found in the left iliac region? | Intestines |
| The study of anatomy and physiology assumes and describes a healthy body. Select the description below that does NOT explain why this approach is useful. | Study of a healthy body is less intimidating and more familiar new students. |
| What is a chain of more than 50 amino acids called? | Protein |
| Mesenchymal cells are most commonly found in ________ connective tissue. | Embryonic |
| Which of the following would not be restricted (limited) by low levels of ATP? | Osmosis |
| One of the descriptions below is from the perspective of anatomical study, the rest are from a physiological perspective. Select the description below that comes from an anatomical perspective. | The innermost lining of the lungs is composed primarily of a thin tissue called simple squamous epithelium. |
| You notice that you cannot read your book through a test tube of fluid held against the print. There is no precipitant in the bottom of the beaker, though it has been sitting for several days in a rack. What type of liquid is this? | Colloid |
| When tissues are injured or infected, chemical signals release and affect the plasma membrane. Endothelial cells respond to the chemical signals with glycoproteins. These proteins attach to white blood cells to the site. What are these glycoproteins? | Cell Adhesion Molecules (CAMs) |
| Which of the following is NOT found in cartilage but is found in bone? | Blood vessels |
| Which organelle plays a role in the synthesis of steroid-based hormones and proteins? | Endoplasmic reticulum |
| What is the organelle that facilitates peptide bond formation between amino acids? | Ribosomes |
| Which organelle plays a critical role in forming spindle fibers for cell division, organize and move organelles as well as giving shape to the cell? | Microtubles |
| Which organelle are dense spherical bodies in the nucleus that are the synthesis site for ribosomal RNA? | Nucleoli |
| Which organelle houses the vast majority of the cell's genetic material? | Nucleus |
| In what phase of mitosis do chromosomes uncoil to form chromatin? | Telophase |
| In what phase of mitosis do chromosomal centromeres split and chromosomes migrate to opposite ends of the cell? | Anaphase |
| In what phase of mitosis do the nuclear membrane and nucleolus disintegrate? | Late prophase |
| In what phase of mitosis do the chromosomes align on the spindle equator? | Metaphase |
| In what phase of mitosis do the centrioles move to opposite ends of the cell? | Early prophase |
| The myocardium (cardiac muscle tissue) undergoes a significant amount of physical stress due to its contractions. You would expect to see relatively large numbers of which of the following embedded within their plasma membrane? | Desmosomes |
| A patient is hyperventilating. The "blowing off" of excessive carbon dioxide causes a decrease in blood H+ concentration. How can the carbonic acid-bicarbonate buffer system function to correct this imbalance? | H2CO3 dissociates to form more H+ and lower pH |
| What is the epithelial membrane that lines the closed ventral cavities of the body? | Serous membrane |
| What is the epithelial membrane that lines body cavities open to the exterior membrane? | Mucous membrane |
| What consists of keratinized stratified squamous epithelium? | Cutaneous |
| What membrane lines the digestive and respiratory tracts? | Mucous membrane |
| What membrane makes up the pleura and pericardium? | Serous membrane |
| What lines blood vessels and the heart? | Endothelium |
