Histology Flashcards
Prostate gland
Seminiferous tubules
Sertoli cells
Leydig cells
Seminal visicle
- honeycomb
- There is a prominent layer of muscle, arranged into inner circular and outer longitudinal.
Epididymis
Testis
Prostate gland
Testis
the thick collagenous capsule on the outside called the tunica albuginea. Can you also identify the seminiferous tubules, which open into a network of anastomosing channels called the rete
Epididymis
These ducts are highly coiled, and make up a single tube in the epididymis that can be up to 6 metres long. This means that several sections of it can be found on a single slide.
Seminal vesicle
Vas deferens
It is a thick walled tube, lined with an inner (I) and outer layer of longitudinal smooth muscle (0) and a middle layer of circular muscle (C).
Pregnant (poss. lactating breast)
- milk in the ducts
- increased acini (purple)
inactive / pre-pregnancy / menopausal
- same number of stromal and acini
- no milk in ducts
Lactating breast
Proliferative phase
Uterus
FSH
Secretory phase
Uterus
LH
Uterine tube
Proliferative phase
In the proliferative phase, facilitated by FSH, the endometrium thickens, connective tissue is renewed, along with glandular structures and ehlicrine arteries. Oestrogen causes the endometrial stroma to become deep and richly vascularised.
Simple tubular glands in the stratum functionalis open out onto the surface, and the endometrium thickens.
Secretoy phase (LH)
In the secretory phase, facilitated by LH, the endometrial glands become cork-screw shaped, and filled with glycogen. They secrete a glycogen rich secretion during the secretory phase (after ovulation).
Primordial follicles
Primary follicle
Primary follicle
A thick glycoprotein layer develops between the oocyte and the zona granulosa, called the zona pellucida.
The secondary follicle develops into a Graffian follicle.
