1

epididymus location head

enlarged head is attached to cr end of the testis where it receives efferent ductules

2

epididymus location body

narrow; connected to testis by membrane which together with testis and epididymus forms testicular bursa

3

remnants of gubernaculum male

proper ligament of the testis and ligament of the tail of the epididymis

4

proper ligament of the testis

fold of visceral vaginal tunic btwn enlarged tail of the epididymis and cd end of testis

5

ligament of the tail of the epididymis

serous fold between tail of epididymis and parietal vaginal tunic

6

tail of the epididymis

gives rise to deferent duct which is enclosed in mesoductus and passes dorsally into inguinal canal

7

mesoductus deferens

suspends deferent duct

8

cremaster muscle

inserts on caudloateral surface of the vaginal tunic

9

external uretheral orifice

located on floor of the vestibule about 12cm from ventral commissure of vulva (vestibule extends crly from labia of vulva to fleshy transverse flap that rises from floor and overhangs the uretheral orifice); ie external uretheral orifice is boundary between vestibule and vagina (vestibule is more cd?)

10

external uterine orifice

in the center of the part of the cervix that projects into the vagina; this is surrounded by folds of cervical mucosa

11

trigone of the bladder

in triangle formed by ureteric and uretheral orificies the mucosa is closely attached to submucosa and does not form folds; the mucosa of the bladder at the internal uretheral orificice (not part of the trigone) will have small longitudinal folds

12

internal anal sphincter

terminal thickening of circular muscle of the rectum. Thick and pale (smooth muscle) lies between external sphincter and anal mucosa

13

external anal sphincter

darker than internal because it is striated voluntary muscle

14

superficial gluteal

coxal tuber and gluteal fascia; insertion: third trochanter; innervated by cr and cd gluteal nerve

15

middle gluteal

Gluteal surface of ilium to greater trochanter; innervated by cr gluteal nerve

16

deep gluteal

deep to cd part middle glut; arises from around ischial spine and inserts on cr part of greater trochanter; innervation cr gluteal nerve

17

semimembranosus

Cd and sacral vertebrea sacrosciatic ligament and ischiatic tuberosity innervation= sciatic nerve and cd gluteal

18

caudal thigh muscle innervation

1. biceps femoris-
vertebral head- cd gluteal nerve
pelvic head- sciatic nerve
2. semitendinosus-
verterbral head- cd gluteal nerve
pelvic head- sciatic nerve
3. semimembranosus- sciatic nerve

19

bulbospongiosus

forms transverse covering over urethera from bulb to its incorporation in the penis

20

ischiocavernosus

covers the crura; this is lateral to bulbospongiosus

21

retractor penis

medial and ventral to bulbospongiosus

22

Accessory gluteal

Deep surface of middle glut arises from similar region glut surface of ilium as middle glut to greater trochanter; associated with trochanteric bursa
