male reproductive organs Flashcards
which muscle lies under the scrotal skin
dartos muscle
what lies under the dartos muscle
- directly
- running up subcutaneous fat
- end product
testes
spermatic chord
inguinal canal
what is the thick layer of tissue that surrounds the testes
spermatic fascia
what forms the spermatic fascia
internal and external fascia derived from abdominal wall
what is this inner membraneous envelope under the spermatic fascia
tunica vaginalis
what does the tunica vaginalis create
fluid filled envelope
remnant of peritoneum
outer parietal layer and inner visceral layer
what are these parts of the testes
epidymis and testes
what is the tough outer fibrous coat of the testes
what is found within the body of the testes
tunica albiginea
seminiforus tubules
what is this area
mediastinum of testes
what happen to spermatazoa as they pass through the epidydimis
mature as they go from head to the tail
what happens to the tail of the epidydymis
loops around to join Vas deferens and passes up the spermatic chord
what is this image showing
layers of the spermatic cord
label the contents of the spermatic cord
the long tube like structure is the ductus deferens
what does the ductus deferens pass into
external inguinal ring (external oblique fibres)
identify testicular artery and ductus deferens crossing ureter
what part of the ductus deferens is shown here
ampulla and katerally a seminal vesicles
smooth muscle walls
where do the seminal vesicles and ductus deferens pass together
ejaculatory duct
base of bladder
internal urethral meatus
prostate
what is in the middle of the ejaculatory ducts before passing into the urthethra
colliculus
identify the three circular masses within the penis
corpora cavernosa
corpora spongiosum
what makes up the outside of the corpora cavernosa
tunica albuginea
where is the corpus spongiosum
urethra contained within
what has been divided here
the prepuce of the penis
what is shown here
coronal sulcus
what is shown here
continuous with corpus spongiosum
two corpora cavernosa behin the glans
what is on either side of the penis
spermatic cords
what is this string of connective tissue
where does it come from
suspensory ligament
anterior abdominal wall
if you remove the suspensory ligament what is directly underneath
pubic symphysis
what connects the penis to the pubic symphysis
triangular ligament
what are these
ischiopubic rami
what are these
what is here
bulb of the penis
running down to the end of corpus cavernosa what is reaches
what muscle surrounds the crura of the penis
ischiocavernosus suround crura
what muscle surrounds the bulb of penis
bulbospongiosus - most propulsion for ejaculation
where is the meeting point for bulbospongiosum and ischiocavernosus
perineal body also joined by external anal sphincter
what is this muscle
superficial transverse perineal muscle underneath this muscle is the peroneal membrane
levetator ani muscle is on either side
what does this show
perinealmembrane and membranous urethra
what part of the urethra is this
prostatic part
what is the next part of the urethra
membranous part
what is the last part of the urethra
penile urethra
