VERIFIED 2027 EDITION
1. What is gross anatomy
...branch of anatomy that deals with the structure of organs and tissues that are visible to the naked eye.
2. Define embryology, cytology & microscopic anatomy
...Embryology- development before birth, Cytology- cells of the body, Microscopic Anatomy- structures to
small to be seen with naked eye
3. The main component of the cytoplasm
...Cytosol
4. What is mitosis
...cell division that results in two daughter cells each having the same # and kind of chromosomes as the
parent nucleus, typical of ordinary tissue growth.
5. Role of leptin in the body
...Leptin regulates energy intake and fat stores so that weight is maintained within a relatively narrow
range. "Leptin is a hormone made by fat cells, that decrease appetite"
6. What is an organic molecule
...are the molecules of life and are built around chains of carbon atoms that are often quite long.
7. Some functions of lysosomes
...they breakdown, degrade and digest safely within a cell
8. What type of epithelium would you find dense microvilli( lining intestines and kidney tubules)
... simple cubodoidal epithelium
9. Where would you find Pseudostratified columnar epithelia
...ciliated is found in the trachea and upper respitory tract; non ciliated is found in the male sperm
10. Major functions of fat
...provides reserve fuel for cell, insulates against heat loss, supports and protects organs
11. What is metabolism
... either Anabolism- which build larger molucules from smaller ones ( storage of energy). Catabolism-
which breaks down from complex molecules to simpler ones ( with the release of energy).
12. What do collagen fibers do for IVDs ( intervertebral discs)
...they provide strentgh with there crosslinks which resits being pulled apart, as well as cushoining.
13. What produces the most ATPs during cellular respiration
...glucose, and the electron transport chain
14. What is a frontal section/cut
...through torso- divides the body by anterior(front) and posterior(back)
15. Improperly digesting nutrients, may indicate a problem of which tissue layer
...simple epithelium
1
, 16. When does the body normally use proteins for energy (ATP)
...When the body is in starvation mode( doesnt have enough carbohydrate or fat calories for Atp
production.
17. Normal constituents of the plasma membrane
...seperates the inracellular fluid wihin the cell and the extracellular fluid outside the cell.
18. What are endocrine glands
ductless glands - secrete hormones directly into blood or lymph ex. pituitary, thyroid
19. What is phagocytosis
...cell eat- ingestion of bacteria or other material
20. The primary function of cellular respiration
...metabolism to form ATP
21. The basic structural material of the body is made of what
...Proteins
22. What are microvilli
...projections from the surface of some cells, have a fuzzy appreance called a brush border (fingerlike
extensions)
23. What is passive membrane transport;
...substances cross the membrane without any energy input from the cell; unlike active transport that
requires energy from the cell
24. What are the characteristics of Psuedostratified Columnar Epithelium
...single layer of cells of differing heights, some not reaching the free surface; nuclei seen at diffrent levels;
may contain mucus secreating cells and bear cilia.
25. What is basal metabolic rate (BMR)
...reflects the energy the body needs to perform only its most essential activities. ( this happens at an in
rest state ; neutral)
26. What is Simple Squamous Epithelial tissue
...one layer, flat egg shaped , allows materials to pass by diffusion and filteration in sites where protection
is not important; secretes lubricating substances in serosae;
27. Why should elderly patients decrease their caloric intake
...becasue their BMR reduces dramaticly, if they increse their calorie intake they will gain weight
28. The functions of tRNA
...carry amino acids to the ribosomes, there they decode mRNA's msg for amino acid sequence in the
polypeptide to be built
29. Salts are ALWAYS _______
...ionic compound
30. Which tissue is highly cellular and vascularized
...muscle tissue
31. The 4 elements that comprise 90% of body matter
...Carbon Hydrogen, Nitrogen, Oxygen
