Lab 2: Microscopic Study of Reproductive Systems Flashcards
The four steps in the process of preparing a tissue for observance under a microscope are:
fixation embedding sectioning staining
Identify the organ to which the two cross sections below belong.
Penis
Match the letter with the correct corresponding structure
A - corpus cavernosum
B - Corpus Spongiosum
C - Urethra
Match the two pictures below with the correct epididymal portion.
Left - Caput (head)
Right - Cauda (tail)
How can you distinguish between the two portions of the epididymis shown below?
The cauda has large sperm deposits in the middle while the caput still has some immature sperm along the sides and some have developing tails
In the picture below representing the caput epididymis, the structure denoted by letter “A” is ___ , while the cell type denoted by letter “B” is ___ .
A - Stereocilia
B - Pseudostratified columnar
Discuss the similarities between the pictures of the three cross-sections presented below.
All three are accessory sex glands. They all have a lot of columnar epithelium and glandular spaces to store what the columnar epithelium produce.
The three organs represented in the pictures below are the ___ gland, ___ (Cowper’s) gland, and ___ vesicles.
prostate
bulbourethral
seminal
The cell type all three cross-sections below have in common are:
simple columnar epithelial
Which cellular layer is the arrow pointing to in this picture of a cross-section of the vas deferens?
Mucosa
True or False: Both the epididymis and vas deferens possess stereocilia, as well as a thick muscularis layer.
False: Both the epididymis and vas deferens possess stereocilia, but only the vas deferens has a muscularis layer.
True or False: the two cross-sections pictured below represent the same organ.
A is the testes - the spermatids are being produced and it has leydig cells on the outside.
B is the epididymis and sperm are maturing - you can see that some have tails.
Label the three layers of the uterus as depicted on the image below.
A - Endometrium
B - Myometrium
C - Perimetrium
To which organ do the cross-sections depicted below belong?
Oviduct
Match each picture with the correct portion of the oviduct.
A - Infundibulum
B - Ampulla
C - Isthmus
What are the 4 defining factors that help differentiate between identifying the ampulla and isthmus of the oviduct?
Folds in lumen
Ciliated epithelium
Lumen diameter
Muscularis region
Identify each follicle type presented below.
A - perimordial
B - primary
C - secondary
D - antral
For each of the four follicle types depicted in the below image, what are their defining feature(s)?
Primordial – squamous cells surrounding oocyte
Primary – single layer of cuboidal cells surrounding oocyte
Secondary – more than two layers of cuboidal cells surrounding oocyte and developed zona pellucida
Antral – antrum is present along with zona pellucida
