Slide 84: Testis
|
H/E
|
|
This slide is a section through the testis.
|
Identify microscopically:
- Tunica albuginea
Mediastinum testis and rete testis Fibrous septae Tubuli seminiferi, smooth muscle cells, spermatogonia, primary spermatocytes, spermatids, spermatozoa and Sertoli cells Interstitial support tissue Leydig cells
Draw and annotate:
A line diagram of the testis. The structures of the tubuli seminiferi and recti, as well as the Leydig cells must be shown in detail.
Reflection:
- Of what type of support tissue does the tunica albuginea, mediastinum testis and the septa consist of?
- What is typical of the structure, especially the nuclei, of the developing reproductive cells?
- What are the distinguishing characteristics of Sertoli cells, as seen in this section?
- What are the identifying characteristics of the Leydig cells?
Slide 84: Epididymis
|
H/E
|
|
This slide is a section through the epididymis to illustrate the ductus epididymis.
|
Identify microscopically:
- Lumen
Epithelium Smooth muscle Support tissue
Draw and annotate:
A line drawing of the ductus epididymis in which a section of the epithelium is drawn in detail.
Reflection:
- What is found in the lumen of the duct?
- What type of epithelium lines the duct, and what is typical of the surface of these cells?
- In what direction is the smooth muscle orientated?
- In what way does the morphology of this tube differ from the general morphology of tubular organs?
Slide 84: Vas deferens
|
H/E
|
|
This slide is a cross section through the vas deferens.
|
Identify microscopically:
- Lumen
Mucosa Smooth muscle Support tissue
Draw and annotate:
A line drawing of the vas deferens.
Reflection:
- What shape does the mucosa take on, and which epithelium lines it?
- How many layers of smooth muscle are found in this duct, and how are they arranged?
