80.Identify the three largest nerves of the lumbar plexus and in general what structures do they supply? (A&M pg 192)
•Obturator Nerve L2- L4 (supply adductor muscles)
•Femoral Nerve L2 – L4 (supply flexors of the hip and extensors of the knee)
•Lumbrosacral Trunk L4- L5 (participates in formation of sacral plexus)
•Obturator Nerve L2- L4 (supply ________ muscles)
•Femoral Nerve L2 – L4 (supply _______ of the hip and ________ of the knee)
•Lumbrosacral Trunk L4- L5 (participates in formation of _______ plexus)
81.What are the branches of the internal iliac artery? (A&M pg 222-223) EX: Obturator, Vesicle, Gonadal, Rectal, and Internal Pudendal.
lumbar and iliac branches
Lateral sacral arteries
Superior gluteal artery
Obturator artery (occasionally from inferior epigastric artery)
Inferior gluteal artery
Uterine artery (females)
deferential artery (males)
Vaginal artery (females, can also arise from uterine artery)
inferior vesical artery
Middle rectal artery
Internal pudendal artery
82.Which of the male reproductive glands makes the largest contribution to semen?
Seminal Glands (Vesicle)
83.In the male this gland can obstruct the urethra.
84.Be able to give, in order, the pathway that sperm would travel through the male duct system into the urethra. (Lab Manual pg 217-218)
•1) Seminiferous Tubules
•2) Tubuli Recti
•3) Rete Testis
•4) Efferent Ductules
•6) Ductus Deferens (vas deferens)
The spermatic veins that form the spermatic cord (Fig. 1147) emerge from the back of the testis, and receive tributaries from the epididymis: they unite and form a convoluted plexus,the plexus ________________,which forms the chief mass of the cord; the vessels composing thisplexus are very numerous, they unite toform three or four veins, which pass along the inguinal canal, and,entering the abdomen through the abdominal inguinal ring, coalesce toform two vein then eventually 1.
The contents of the abdominal cavity may protrude into the spermatic cord, producing an ________ inguinal hernia.
contents of spermatic cord
arteries: testicular artery, deferential artery, cremasteric arterynerves: nerve to cremaster (genital branch of the genitofemoral nerve) , sympathetic nerves vas deferens (ductus deferens)pampiniform plexuslymphatic vesselsprocessus vaginalis (remains of)
86.What is the action of the cremaster (skeletal muscle) and dartos (smooth) muscles? (A&M pg 130-132)
•Both help move the testicles to/away from the body, depending on
temperature. Dartos wrinkles the scrotum when cold, helping to hold
scrotum closer to body (testicular elevation)
Trace the pathway of a fertilized ovum from the ovary to implantation. Where does fertilization normally take place?
egg starts in ovary
ishamus body of uterus and implants onto wall (inturmural?)
three layers of the uterus? (A&M pg 237)
fertilization of the egg typically takes place in the _______ part of the fallopin tubes
uterine tube has four named parts:_____________ is the funnel shaped opening - fimbria encircle this opening;_________ is a dilated region that connects the with the ________; isthmus is the constricted part nearest the uterus; _________ part is
within the uterine wall
__________ _________ is a result of implentation to be somewhere else then uterus and instead implants in mucosa of uterine tube (usually), but implantation can also occur in the cervix, ovaries, and abdomen.
Levator Ani, Coccygeus muscles and associated facias muscles form the pelvic ________
92.What are the boundaries of the urogenital triangle? Male? Female? (A&M pg 248-253)
•root of scrotum/penis in males and the external in females and anterior anal triangle
The urogenital (UG) triangle is the ________ portion of the perineum.
the _________ ________ contains the root of the scrotum and penis in males and the external genitalia in females.
__________ muscle of the pelvic floor can be torn in childbirth. (which is the most medial part of the levator ani)
