SUGER: Histology Flashcards
How many medullary pyramids are found in each kidney
10-15
Describe the course of blood through the kidneys
Renal artery ->
How many layers are present in the muscularis propria of the urinary bladder
3
What epithelium lines the prostatic urethra
proximal - pseudo-stratified columnar (urothelium)
Distal - Non-keratinised stratified squamous (male and female)
On what part of the urethra in males and females are the external urethral sphincter found
Over the membranous urethra
What structure is found under the urothelium of the prostatic urethra
Dense fibrous connective tissue
Where is the bulbourethral gland located
In the membranous part of the urethra.
What is the bulbourethral gland equivalent in females
Bartholin Glands
What epithelium lines the seminiferous tubules
columnar epithelium and sertoli cells - germinal epithelium
What cells form the blood testis barrier
Sertoli cells
What epithelium lines the epididymis
Pseudo-stratified columnar epithelium with stereocilia
Why do the epididymis have stereocilia
For absorption
What epithelium lines the vas deferens
Pseudostratfiied columnar epithelium
What is the difference in the epithelium of the epididymis and the vas deferens
In the vas deferens, the microvilli and cells are shorter
How many layers of the muscularis propria are present in the vas deferens
Three
What are the three layers of the muscularis propria
Inner longitudinal
Outer circular
Outermost longitudinal
What hormone stimulates the seminal vesicle
Testosterone
What epithelium lines the seminal vesicle
Simple columnar epithelium
What substances does the prostatic epithelium secrete
Acid phosphatase
What can be seen in the prostatic epithelial lumen
Calcified glycoprotein
What does the bulbo-urethral gland secrete
Watery galactose rich secretion
What is the tunica albuginea made of
Collagen
What is the tunica vaginalis made of
Mesothelium
What is the prepuce and glans made of
Non-keratinised stratified squamous epitheliumn
What epithelium lines the vagina
Stratified squamous epithelium that becomes keratinised towards the vulval end.
Stratum basal, stratum spinosum, stratum granulosum, stratum corneum
Skin vs Vagina: Vagina has a very thin corneum and looks spongy
What lines the ectocervix
Non-keratinised stratified squamous epithelium
What lines the endocervix
Simple columnar epithelium
What lines the cervical canal
Columnar epithelum thrown into folds
What is the name of the structure under the epithelium of the cervix
Stroma
What is found in the cervical stroma
fibrous connective tissue and smooth muscle which relaxes during childbirth
Describe the difference in appearance of the cervical lining
First half - Thin and watery
Second half - Viscous following ovulation to prevent microbe entry
What is the transformation zone of the cervix
The junction between the ectocervix and endocervix
How many layers are there in the muscularis propria of the uterus
3
What epithelium lines the uterine body
Endometrial epithelium - simple columnar with tubular glands
What is the development of the uterus divided into
Proliferative and secretory phase
What is the proliferative phase
First half, stroma thickens and length glands increase
What does Alcian Blue stain
- GAG
- Mucous
- Mast Cells
- Cartilage
All blue
What does Eosin stain
- Colloidal Proteins
- Plasma
Pink
What pH does eosin stain
acidic pH
What does iron haematoxylin stain
Nuclei
Elastic Fibres
Black
What does PAS stain
Hexose sugars Goblet cell mucins Cartilage Matrix Glycogen Basement Membranes Brush border
All magenta
