Flashcards in HISTO LEC - MALE REPRO Deck (31):
1
capsule of testis
pleura-like (w/ serous fluid that acts as lubricants)
tunica vaginalis
2
capsule of testis
– gives rise to septa; forms testicular lobules
tunica albuginea
3
capsule of testis
– loose CT; deepest layer; w/ blood and lymphatic vessels
tunica vasculosa
4
non-proliferating cells
non-spermatogenic cells
influenced by FSH
“nurse cells”
sertoli cells
5
spermatogenic cells
dependent on testosterone
give rise to spermatocytes
Germinal cells
6
excretory ducts innervated w/ sympathetic nervous system
Epididymis*
Vas deferens*
7
excretory duct
Straight tubules
No convolutions
tubuli recti
8
excretory duct
convoluted
Highly vascular collagenous tissue
rete testis
9
excretory duct
With myoid cells: push sperm cells towards epididymis
rete testis
10
excretory duct
Lined by simple cuboidal epithelium: reabsorbs CHON and K+
rete testis
11
excretory duct
With surface microvilli and cilium: aid sperm cells to reach epididymis
rete testis
12
Lined by single layer of epithelium
-tall or short columnar
- ciliated or non-ciliated
ductulus efferens
13
Cells contain brown pigment
Surrounded by smooth muscle (propels sperm cells)
ductulus efferens
14
Tube of smooth muscle
Lined by PSCCE
With stereocilia
Function: accumulation, storage and maturation of spermatozoa
epididymis
15
Cut in vasectomy
Lined by PSCCE
Surrounded by smooth muscles
Longitudinal foldings
ductus (vas) deferens
16
-distal portion of vas deferens
-connected to seminal vesicle
Ampulla
17
Ampulla of vas deferens connected to the seminal vesicle (accessory gland)
ejaculatory duct
18
shortest portion of the urethra
membranous urethra-
19
longest portion of urethra
penile
20
provides nutrition and fluid for the spermatozoa
accessory glands
21
its secretions consist of seminal vesicle - 85% of the total volume of seminal fluid
seminal vesicle
22
Lined by pseudostratified tall columnar epithelium
With secretory cells
seminal vesicle
23
Surrounded by thin muscular layer
With ampulla
seminal vesicle
24
Produce yellowish fluid (rich in fibrinogen, fructose, Vit.C and prostaglandin)
seminal vesicle
25
Honey-combed appearance
seminal vesicle
26
Produce whitish fluid
Complex tubulo-acinar glands
prostate gland
27
prostate gland is Lined by stratified(2-layered) epithelium with 2 types of cells?
1. tall columnar cells – secretory
2. flattened cells
28
Lies beneath the membranous urethra
Produce secretions that alkalinize the urine
bulbourethral gland
29
other name for corpus spongiosum
corpus cavernosum urethrae
30
dilate during erection
helicine arteries
