Q

Accessory glands

A

Seminal vesicles - glandular diverticulum - 60% of sf, nutrition + stim of motility - survival of sperm in vagina
Prostate - 30% of SF. Citric acid, enzymes, proteins
Bulbourethral glands - urogenital diaphram - alkaline mucus. Compound tubular alveolar - similar to mucus secreting glands.

A

Chestnut like

20
Q
Prostate secretes
Rich in?
Proteins can be used for?
The concretion?
How differ from thyroids?
A

Alkaline fluid - neutralised acidic ph of vagina
Rich in citric acids, proteolytic enzymes, liquifin -> coagulated sperm(semen) into vagina
Proteins: prostate specific antigen - detect cancer
Copora amylacea - also found neuroglia and pul alveoli
Epi, structure and mat of secretory uni. (Tubuloalveolar = prostate)

21
Q

Carcinoma of prostate

A

Peripheral - most cases of carcinoma
Transitional - around urethra/mantellar zone - benign hyperplasia
Central - resistance to carcinoma - aorund ejaculatory ducts

26
Q

Genital tract (4)

A

Entry of oocyte into fallopian tube
Sperm into fallopian tube
Fertilisation - ovum into uterus
Implantation + development of ovum in mucosal lining of uterus

27

12cm

28
Q

Uterine tubes site of? 4 parts? Lumen and sm

A

Site of fertilisation and cleavage of zygote
4 parts : infundibum, ampulla, isthmus, intramural portion - extends into uteric wall
Lumen decreases, increase in sm proportion (muscularis externa)

29
Q

Structure of uterine tube -

Simple columnar - cilia
Secretory (non-cilia)
LP -> CT
SUBmucosa - lacking
Muscularis - 2 - inner circ, outer spiral
30
