BIOS 255 Comprehensive Exam
1. maintenance of a stable internal environment with the contribution of all
organ systems: What is homeostasis?
2. -Stimulus
-Receptors
-Control center
-Effector
-Response: What are the components of a homeostatic mechanism?
3. Body REVERSES, or goes against, an original stimulus to return to home-
ostasis
Example: Blood glucose regulation after eating.: What is a negative feedback
mechanism?
4. Amplifies the change from the normal level. (Agrees with the change)
Example: Childbirth, blood clotting: What is a positive feedback mechanism?
5. negative: What feedback mechanism is most common?
6. Below; at a lower level: Inferior
7. Above; higher level: Superior
8. Side; Away from the midline of the body: Lateral
9. Closer to the point of attachment: Proximal
10. Father away from the point of attachment: Distal
11. Toward the midline of the body: Medial
12. divides body into left and right: Sagittal
13. Divides body into upper and lower parts: Transverse
14. toward the front of the body: Anterior
15. toward the back of the body: Posterior
16. Divides the body into anterior (front) and posterior (back) portions.: Frontal
plane
17. Electrons: Which part of the atom is involved in chemical reactions?
18. Protons: Which part of the atom makes up the atomic number?
19. Measurement of hydrogen ion concentration
- pH < 7: Acidic
-pH > 7: Alkaline (basic)
-pH = 7: neutral: pH scale
20. Protein synthesis: What is the main function on rough endoplasmic reticulum?
21. Mitosis: What kind of cell division results in a diploid, increasing the number of
cells?
22. 23 pairs: How many pairs of chromosomes do humans have?
23. Meiosis: What kind of cell division results in a haploid?
24. Splits genetic material in half, producing a diploid: Meiosis I

, BIOS 255 Comprehensive Exam
25. Separates sister chromatids
-four haploid daughter cells
-develop into egg or sperm: Meiosis II
26. Chromosomes become visible, nuclear envelope dissolves, spindle forms-
: Prophase
27. Chromosomes line up in the middle of the cell: Metaphase
28. Chromosomes separate and move to opposite ends of the cell: Anaphase
29. Chromosomes move to opposite ends of the cell and two nuclei are
formed.: Telophase
30. epithelial, connective, muscle, nervous: What are the 4 types of tissues?
31. -Cells sit on basement membrane
-Has apical surface and basal surface
-Avascular
-Polarity
-Innervated: What are the properties of epithelial tissue?
32. Cell regeneration is triggered.: What occurs when the apical surface of epithe-
lial cells separate from the basement layer?
33. heart, blood vessels, kidneys, lungs: Where can simple squamous epithelium
be found?
34. urinary bladder: Where can you find transitional epithelium?
35. passages of the respiratory system
various tubes of the reproductive systems: Where can columnar epithelium be
found?
36. Helps move things along (moves mucous and foreign particles away): -
What function does cilia have?
37. Secrete their products by exocytosis
-Salivary glands
-Sweat glands
-Pancreatic glands: merocrine glands
38. **Mammary glands
-accumulates products within but only the apex ruptures: apocrine glands
39. **Sebaceous glands
-accumulate their products within them until they rupture: holocrine glands
40. -Loose connective tissue
-Bone
-Cartilage
-Blood: What are some examples of connective tissue?
