male and female pelvis Flashcards
spermatic chord during development…
follows testes through the inguinal canal
spermatic chord contents
ductus deferens (vas deferens) testicular artery pampiniform plexus of veins cremasteric artery, sympathetic nerves lymphatics of the testis and epididymis.
role of epididymus and where is it
maturation and storage of sperm. its in the testes
name 2 structures seen in the testes and what occurs here?
seminiferous tubules
tubica albuguinea - partitions between
where spermatogenesis occurs
order from anterior to posterior the structure of the pelvis of male
penis testes (vas deferens loops around pubic symphysis and bladder) pubic symphysis urinary bladder (below is the prostate) seminal vesicles rectum
role of seminal vesicles
secretes alkaline seminal fluid
role of the prostate
secretes prostatic fluid
journey of sperm testes to ejaculation
testes, epididymus, vas deferns, inguinal canal, seminal vesicles, ejaculatory duct, prostatic urethra, membranous urethra
describe structure of the penis
2 corpus cavinosum with deep artery running through, posterior to this is one corpus spongiosum that has the urethra running through it.
holding all together is bucks fascia
name and describe the two ligaments of the penis
suspensory ligament- connects erectile bodies to pubic symphysis, from deep fascia
fundiform - abdominal subcutanoud tissue. wrap around the penis like a sling from linea alba to pubic symphysis
name and describe location of the three major blood vessels supplying penis and state what they come from
all from the internal pudendal artery from internal iliac
dorsal artery - most superficial runs into the head/glans of penis
deep artery - through corpus cavinosum
bulbourethral - most inferior and supplies spongiosum
innervation of penis
Sensory and sympathetic innervation to the skin and glans penis is supplied by the dorsal nerve of the penis - pudendal
cavernous nerve - Parasympathetic innervation
order from anterior to posterior the structure of the pelvis of female
pubic symphisis, bladder, uterus, rectum
name and describe the 3 ligaments of the female pelvis
broad - extends from the sides of the uterus medially to the pelvic sidewalls laterally and the pelvic floor inferiorly
ovarian - connects the ovary to the lateral surface of the uterus
Suspensory - connects the ovary to the wall of the pelvis
what ligament goes through the inguinal canal
round ligament - ligamentum teres
roles of the pelvic bone
Transfer of weight from the upper axial skeleton to the lower appendicular components of the skeleton, especially during movement.
Provides attachment for a number of muscles and ligaments used in locomotion.
Contains and protects the abdominopelvic and pelvic viscera.
difference between the male and female pelvis girdle
Women have :
A wider and broader
lighter in weight
An oval-shaped inlet compared with the heart-shaped
Less prominent ischial spines
A greater angled sub-pubic arch
A sacrum which is shorter, more curved and with a less pronounced sacral promontory.
what is the origin of theroundl ligament and where is it
a remnant of the embryonic gubernaculum.
It originates at the points at which the fallopian tubes enter the uterus, and attaches to the labia majora, passing through the inguinal canal.
describe the development of the testes
While the gonads arise in the upper lumbar region, they are each tethered to the scrotum or labia by the gubernaculum – a ligamentous structure formed from mesenchyme.
As the body of the fetus grows, the testes become more caudal. They pass through the inguinal canal around the 28th week, and reach the scrotum by the 33rd week. During their descent, the testes retain their original blood supply, with the testicular arteries branching from the lumbar aorta.
The scrotal ligament is the adult remnant of the gubernaculum.
