| What is a corticosteroid and calcitrol? | Metabolic regulators |
| What happens in the G2 Phase? | Finishing of protein synthesis and centriole replication |
| What is the function of smooth ER? | Synthesize lipids and carbohydrates |
| What are globular proteins? | Soluble spheres with active functions |
| What happens in the S Phase? | DNA replication and histone synthesis |
| Characteristics of Reticular fibers | Resists force in many directions (sheaths around organs) |
| What are the 6 functions of membrane proteins? | Anchoring, recognition, enzymes, receptor, carrier, channels |
| What is a Triglyceride? | Fat storage molecule |
| What does mesothelium line? | Body cavities |
| What are the 3 components of the cell membrane? | Lipids, carbohydrates, proteins |
| What are peroxisomes? | Enzyme-containing vesicles that break down fatty acids and organic compounds and produce H2O2 |
| What does endothelium line? | Heart and blood vessels |
| What are Prostaglandins? | Short-chain fatty acids, local hormones |
| Characteristics of collagen fibers | Most common in connective tissue proper, resists force in 1 direction (tendons and ligaments) |
| What is radiant energy? | Electromagnetic (energy in waves) |
| What are the 5 types of lipids? | Fatty acids, eicosanoids, glycerides, steroids, phospholipids, and glycolipids |
| What happens in the G1 phase? | Cell growth, organelle duplication, protein synthesis |
| What is the function of ER? | Synthesis of protein, storage of synthesized molecules, and detoxification of drugs and toxins |
| What are fibrous proteins? | Structural sheets or strands |
| What are the 2 types of Eicosanoids? | Leukotrienes and prostaglandins |
| What is Merocrine secretion? | Produced by Golgi body released by vesicles (sweat glands) |
| What are the 3 membrane carbohydrates? | Proteoglycans, glycoproteins, and glycolipids |
| What are the 4 types of steroids? | Cholesterol, estrogen and testosterone, corticosteroid and calitrol, and bile salts |
| What are the characteristics of epithelial tissue? | Cellularity, polarity, attachment, avascularity, and regeneration |
| What are the functions of epithelial tissue? | Provide physical protection, control permeability, provide sensation, and produce specialized secretions |
| What is the function of simple squamous epithelium? | Absorption and diffusion |

| What are the types and functions of glandular epithelium? | Endocrine glands that release hormones into interstitial fluid and have no ducts and exocrine glands that produce secretions onto epithelial surfaces through ducts |
| What is dense regular connective tissue for? | Attachment and stabilization (tendons, ligaments) |
| What is dense irregular connective tissue for? | Layered in skin, around cartilage, around bones, and form capsules around some organs (liver, kidneys) |
| Characteristics of fibrocartilage | Limits movement, prevents bone to bone contact, pads knee joints, found between pubic bones and intervertebral discs |
| Characteristics of Hyaline cartilage | Stiff, flexible support, reduces friction between bones, found in synovial joints, rib tips, sternum, and trachea |
| Where is areolar tissue found? | Holds blood vessels and capillary beds (under skin) |
| Where is reticular tissue found? | Supportive fibers that support functional cells, reticular organs, spleen, liver, lymph nodes, and bone marrow |
