GENITAL ORGANS THE MALE INTERNAL GENITAL

THE MALE INTERNAL GENITAL ORGANS
The testis
The epididymis
The ductus (vas) deferens
The seminal vesicles
The ejaculatory ducts
The prostate gland
The bulbourethral gland

THE MALE EXTERNAL GENITAL ORGANS
the penis
the scrotum
the spermatic cord

The testis
The exocrine function means producing male genital cells – spermatozoa
Тhe endocrine function means producing testosterone (male sexual hormone)

The testis
Two surfaces:
medial and lateral
Тwo borders:
anterior and posterior
Тwo poles:
superior and inferior

The testis
tunica albuginea
mediastinum testis
septa (trabeculae)
lobules

Canaliculi of the testis
convoluted seminiferous tubules
straight seminiferous tubules
network of the testis
efferent ductules of the testis

The epididymis
head
body
tail

Ductus deferens
Four parts:
the scrotal
the funicular
the inguinal
the pelvic. In the terminal portion of the vas deference it becomes wide and spindle-shape, forming the ampulla of the vas deference

The wall of the ductus deference is composed of three layers:
an outer adventitious coat
a middle muscular coat
an inner mucous coat

The seminal vesicles
It is a tubular gland
The seminal vesicles contribute 60 percent of the volume of semen
The junction of the duct of the seminal vesicles with ampulla of the ductus deferens marks the ejaculatory duct
Opens into prostate part of the urethra

The prostate gland
The prostate gland is partly muscular and partly glandular organ
It secretes a component of semen
The prostate has:
base and apex
anterior, posterior and inferolateral surfaces
left, right and middle lobes

The bulbourethral glands or Cowper’s glands
They are situated at the base of the penis, covered by the fascia of the urogenital diaphragm
The excretory duct opens into the spongy portion of the urethra
The secretion of the glands protects the urethral walls from irritation by the urine

Scrotum
Skin skin
Dartos tunic subcutaneous connective tissue
External spermatic fascia superficial fascia of the abdomen
Cremasteric fascia proper fascia of the external oblique abdominal muscle
Cremaster muscle internal oblique abdominal and transversal muscles
Internal spermatic fascia transverse fascia
Vaginal tunic peritoneum

Spermatic cord
the vas deferens;
testicular artery;
convoluted (venous) pampiniform plexus;
the artery and veins of the vas deferens;
the lymphatic vessels of the testis and the epididymis;
the nerves;
the vestige of the processus vaginalis

The penis consists of:
root
body
glans penis
two corpora
cavernosa
corpus spongiosum

There are three parts has the male urethra
prostatic
membranous
spongy

The constrictions of the male urethra
internal urethral orifice
membranous part
external urethral orifice

The dilations of the male urethra
prostatic part
bulbous portion
fossa navicularis

Internal female organs
ovaries
uterine tubes
uterus
vagina

External female organs
mons pubis
clitoris - is a structure analogous to the corpora cavernosa of the penis
labium majus limit the glottis (rima) pudendi
labium minus pudenda - bound the vestibule of the vagina
vestibule of the vagina
greater vestibular gland
bulb of vestibule - is a structure analogous to the corpus spongiosum of the penis

The ovary
The exocrine function is to produce ovules
The endocrine function is to produce female sexual hormones
The ovary has:
two surfaces: medial and lateral
two extremities: tubal and uterine
two borders: free posterior and anterior mesovarium

The ovary has is lined from the outside by germinal (embryonic) epithelium under which is the connective tissue layer - tunica albuginea
The substance of the ovary is divided into: superficial cortex
deeper medulla
The position of each ovary is stabilized by the mesovarium and by supporting ligaments:
the ovarian ligament and
suspensory ligament

Appendages of the ovary
epoophoron
paroophoron

Position of the uterus
anteversio
anterflexio
lateroposition
retroversion
retroflexio

The uterus
fundus
body
isthmus
neck: supravaginal
vaginal parts
uterine cavity
cervical canal

The wall of the uterus
serous coat - the perimetrium
muscular coat – myometrium: internal and external longitudinal and middle circular layers
mucosa - endometrium

The ligaments of the uterus
the broad ligament consists of the mesovarium
mesosalpinx
mesometrium
the round ligament

Uterine tube or Fallopian tube
ostium:
abdominal
uterine
parts:
uterine part
isthmus
ampulla
infundibulum, which ends with the fimbria

The wall of the uterine tube
the serous coat
the muscular coat: internal circular and external longitudinal
the mucosa
