a. Bellini -

b. Disse -

c. Bowman -

d. Golgi -

e. Pacini -

f. Purkinje -

g. Paneth -

h. Malpighi -

i. Leydig -

j. Herring -

2. (16 points). Indicate the type of connective that comprises or supports each of the structures listed below by writing the appropriate letter in the space to the left of the name of the structure.

_____ dermis of thick skin A. mucous c.t.
_____ mucosa of the esophagus B. loose c.t.
_____ umbilical cord C. dense irregular c.t.
_____ pinna of the ear. D. dense regular c.t
_____ & _____ bronchus E. reticular c.t.
_____ & _____ tendon F. elastic c.t.
_____ tunica media of a large artery G. adipose c.t.

3. (32 points) For each of the substances listed below, list a cell that produces it and describe its function:

a. mineral corticoids -

b. luteinizing hormone-

c. chorionic gonadotropin -

d. oxytocin -

e. albumin -

f. histamine -

g. myelin -

h. hydrochloric acid -

4. (12 points) Name a specific blood vessel that brings blood into each of the following:

a. hepatic sinusoid -

b. glomerular capillary tuft

c. renal medulla -

d. spleenic white pulp -

e. tunica adventitia of an elastic artery -

f. marrow cavity of a long bone -

5. (24 points) Define the following terms as they relate to histology and give one example of each:

a. stem cell -

b. argyrophilic -

c. heterochromatin-

d. contrast -

e. adventitia -

f. lamina propria -

Answer the following questions on the lined paper provided:

6. (10) What is tissue fluid, where is it found, how is it produced, and what are its functions?

7. (20 points) There are many tissues in the body that are characterized by the production of mucus. What exactly is mucus and what is it made of? Also, describe the sources of mucus in the upper respiratory tract and stomach and compare and contrast the functions of mucus in these two locations.

8. (40 points) Throughout this course we have stressed the relationship between histological structure and physiological function. Choose one of the organ systems listed below and discuss how the structure of the tissues and cells that comprise the system contribute to the functions performed by the system. As appropriate discuss the relationship between structure and function at the sub-cellular, cellular, tissue, and organ levels. Be sure to discuss the role and organization of the epithelia, glands, connective tissues, and other types of tissues found in the system. Make your answer as complete as possible.

a. Nervous system

b. Cardiovascular system

c. Lymphoid (immune) system

d. Digestive system


When you have completed answering the questions:
