Lab 8 Learning Issues

Question 1

epididymus location head

Answer 1

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

Question 2

epididymus location body

Answer 2

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

Question 3

remnants of gubernaculum male

Answer 3

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

Question 4

proper ligament of the testis

Answer 4

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

Question 5

ligament of the tail of the epididymis

Answer 5

serous fold between tail of epididymis and parietal vaginal tunic

Question 6

tail of the epididymis

Answer 6

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

Question 7

mesoductus deferens

Answer 7

suspends deferent duct

Question 8

cremaster muscle

Answer 8

inserts on caudloateral surface of the vaginal tunic

Question 9

external uretheral orifice

Answer 9

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?)

Question 10

external uterine orifice

Answer 10

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

Question 11

trigone of the bladder

Answer 11

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

Question 12

internal anal sphincter

Answer 12

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

Question 13

external anal sphincter

Answer 13

darker than internal because it is striated voluntary muscle

Question 14

superficial gluteal

Answer 14

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

Question 15

middle gluteal

Answer 15

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

Question 16

deep gluteal

Answer 16

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

Question 17

semimembranosus

Answer 17

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

Question 18

caudal thigh muscle innervation

Answer 18

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

Question 19

bulbospongiosus

Answer 19

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

Question 20

ischiocavernosus

Answer 20

covers the crura; this is lateral to bulbospongiosus

Question 21

retractor penis

Answer 21

medial and ventral to bulbospongiosus

Question 22

Accessory gluteal

Answer 22

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