HISTO LEC - MALE REPRO Flashcards
capsule of testis
pleura-like (w/ serous fluid that acts as lubricants)
tunica vaginalis
capsule of testis
– gives rise to septa; forms testicular lobules
tunica albuginea
capsule of testis
– loose CT; deepest layer; w/ blood and lymphatic vessels
tunica vasculosa
non-proliferating cells
non-spermatogenic cells
influenced by FSH
“nurse cells”
sertoli cells
spermatogenic cells
dependent on testosterone
give rise to spermatocytes
Germinal cells
excretory ducts innervated w/ sympathetic nervous system
Epididymis*
Vas deferens*
excretory duct
Straight tubules
No convolutions
tubuli recti
excretory duct
convoluted
Highly vascular collagenous tissue
rete testis
excretory duct
With myoid cells: push sperm cells towards epididymis
rete testis
excretory duct
Lined by simple cuboidal epithelium: reabsorbs CHON and K+
rete testis
excretory duct
With surface microvilli and cilium: aid sperm cells to reach epididymis
rete testis
Lined by single layer of epithelium
- tall or short columnar - ciliated or non-ciliated
ductulus efferens
Cells contain brown pigment
Surrounded by smooth muscle (propels sperm cells)
ductulus efferens
Tube of smooth muscle
Lined by PSCCE
With stereocilia
Function: accumulation, storage and maturation of spermatozoa
epididymis
Cut in vasectomy
Lined by PSCCE
Surrounded by smooth muscles
Longitudinal foldings
ductus (vas) deferens
- distal portion of vas deferens
- connected to seminal vesicle
Ampulla
Ampulla of vas deferens connected to the seminal vesicle (accessory gland)
ejaculatory duct
shortest portion of the urethra
membranous urethra-
longest portion of urethra
penile
provides nutrition and fluid for the spermatozoa
accessory glands
its secretions consist of seminal vesicle - 85% of the total volume of seminal fluid
seminal vesicle
Lined by pseudostratified tall columnar epithelium
With secretory cells
seminal vesicle
Surrounded by thin muscular layer
With ampulla
seminal vesicle
Produce yellowish fluid (rich in fibrinogen, fructose, Vit.C and prostaglandin)
seminal vesicle
Honey-combed appearance
seminal vesicle
Produce whitish fluid
Complex tubulo-acinar glands
prostate gland
prostate gland is Lined by stratified(2-layered) epithelium with 2 types of cells?
- tall columnar cells – secretory
2. flattened cells
Lies beneath the membranous urethra
Produce secretions that alkalinize the urine
bulbourethral gland
other name for corpus spongiosum
corpus cavernosum urethrae
dilate during erection
helicine arteries
between the venous spaces of the erectile tissues
►smooth muscles, elastic and collagen fibers
trabeculae
