Histology

WEEK 1

ENDOCRINE ANATOMY & HISTOLOGY LAB

Exercise #36

LAB 36  (pages 275 & 281-282) + tissue drawings

NOT 285-286

DO NOT DRAW THE "Pancreas showing changes from diabetes mellitus"

 

Write in full sentences where more than one word is indicated and label all listed structures on the drawings

REQUIREMENT: USE COLORED PENCIL FOR THE DRAWINGS—POINTS WILL BE TAKEN FOR DRAWINGS THAT DO NOT HAVE THE STRUCTURES LABELED.

Look at the full size models in the classroom and the diagrams in the lab & textbook. There are photos of endocrine tissue in Exercise 36 and the histology cards for support. However, histology drawings must be from images the student sees under the microscope. This material will appear on the practical so you will want to view all of the slides and know the location of all of the endocrine structures. You may also want to write little descriptions of the structures so that you can identify them later. (The lab is open on Fridays for those of you who do not complete the assignment)

Familiarize yourself with the location, function, and general macroscopic and microscopic structure of the:

pituitary gland (hypophysis)

thyroid gland

pancreas

posterior pituitary gland (neurohypophysis)

anterior pituitary gland (adenohypophysis)

parathyroid gland

adrenal gland (both the medulla and the cortex)

 

thyroid gland

 

para-thyroid gland

pituitary gland (hypophysis)

 

adrenal gland

 

pancreas

anterior

(adeno-hypophysis)

posterior

(neuro-hypophysis)

follicles

colloid

follicular cells

extra-follicular cells (parafollicular)

chief cells

secretory cells

pituicytes

capsule

cortex

medulla

acinar cells

pancreatic islets

(Isles of Langerhan)
