Male Anatomy Review Flashcards
Describe the composition of the penis
The body of the penis consists of three tightly bound, cylindrical masses, the right and left corpora cavernosa and the corpus spongiosum. The corpus spongiosum projects distally to expand into the glans of the penis and transmits the urethra
The ____ aa. flow through the right and left corpora cavernosa
deep aa. of the penis (these are responsible for erection
What is the GSA to the penis?
the dorsal nerve of the penis (3rd branch of the pudendal n)
Describe the mechanical support of the penis
the body of the penis is supported by two condensations of deep fasica- the fundiform ligament which is derived from the linea albea and the suspensory ligament of the penis which attaches to the symphysis pubis
Other support of the penis?
the root of the penis is not externally visible and consists of right and left crura which are continuous with the corpora cavernosa and the bulb of the penis which is continuous with the corpus spongiosum
What lymph nodes do the ovaries/testes drain to?
para-aortic lymph nodes
What lymph nodes does the distal 1/2 of vagina/vulva/scrotum drain to?
superficial inguinal nodes
What lymph nodes does the proximal 1/2 of the vagina/uterus drain to?
obturator, external iliac, and hypogastric nodes
Why is varicocele more common in the left gonad?
The left spermatic vein enters the left renal vein at a 90 degree angle so flow is less continuous
