Male genital system Flashcards
The lymph vessel ends in
in the lumbar aortic and internal iliac lymph nodes.
The testicular nerve plexus is formed by
autonomic fibers from the aortic and caudal mesenteric ganglion.
The testis and epididymis are highly vascularized with blood from the testicular artery, which enter
the tunica albuginea and the mediastinum.
The testicular vein forms a pampiniform plexus around the testicular artery before it reaches the testis, the right one joins the …………. and the left one ends in the …………
the caudal vena cava
left renal vein
The tail extremity of the testis is connected to the tail of epididymis by the
proper ligament of testis.
The tail of epididymis is in turn connected to the scrotum by the
ligament of tail of epididymis
High temperature, old age and debility make the scrotum ………, while cold, young age and good condition make the scrotum…………… to the testes.
elongated and flaccid
short, corrugated and closely applied
The skin is thin elastic, soft to the touch. Why?
due to presence of numerous sweat and sebaceous gland.
What is colour of the skin in testis horse, dog & ox?
It is pigmented in horse and dog and fleshy colored in ox.
It extends from the tail of epididymis to the beginning of the pelvic urethra to open on
on the colliculus seminalis.
It begins by a tortuous part and gradually becomes straight and runs along the medial side of the head of epididymis and continues in the spermatic cord in a special fold called the ………..and enters the abdominal cavity through …………
plica ductus deferens
the inguinal canal.
It then turns caudally to enter where it courses caudally in ……., medial to………
the genital fold,
the seminal vesicle.
The wall of the terminal part of the ductus deferens is thickened forming ………., which is well developed in ………, poorly developed in ……… and absent in …………
the ampulla ductus deferns
ruminants and equines
canine
swine and felines
Beyond the ampulla, the deferent duct abruptly diminishes in the size and opens on the colliculus seminalis either independently as ……… or unites with the terminal part of the corresponding vesicular gland forming the ejaculating duct as in ……..
swines, canines and camel
ruminants and equines.
…………….is formed from all structures, which suspend the testis in the scrotum
The spermatic cord
It is closely invested by ………. (which covers the cord) and surrounded by the narrow proximal part of the ……… (which lines the inguinal canal) .
tunica vaginalis visceralis
tunica vaginalis partialis
The two tunica are continuous with each other along the caudal aspect of the cord by ………
mesofuniculum
The spermatic cord is surrounded by the most layers of the scrotum. It is short and thick in ……….. and long in other species.
equines
…………. removal of the testicles by either surgical or non-surgical methods
Castration
The root of the penis consists of ……… which are attached to the ischial arch and the …………… which is present between the two crura.
two crura
bulb of penis
The body of the penis is a firm structure made up of erectile tissues termed ………… and the penile urethra enclosed in the………….
paried corpus cavernosum penis
corups spongiosum penis
The body of the penis close to the root is firmly attached to the ventral aspect of the pelvic symphysis by two strong flat bands of connective tissue termed ………..
the suspensory ligament of penis.
In ruminants and swines, the body of penis is folded upon itself forming S-shaped flexure called ……….
sigmoid flexure
The position of the sigmoid flexure is ………..in swines and ……….in ruminants.
prescrotal
postscrotal
The two corpora cavernosa are separated by the ……….., which is a thin fibrous structure. It is intact in carnivores and interrupted in the other species.
penile septum
The muscles of both sides ( M. retractor penis ) meet under the anus forming the …………. and continue on the urethral surface of the penis.
suspensory ligament of the anus
The arterial supply of the penis is derived form the internal pudendal artery ………, internal and external pudendal arteries in …….. and the two pudendal arteries in addition to the oburator artery in……….
in ruminants and swines
carnivores
equines
