Question 1

what are the borders of deep inguinal ring

Answer 1

Profound inguinal ring

• Dist/ventr?: Lig. Inguinale (made by EO tendon)
• Cran: m. oblique internus abdominalis
• Caud: Rectus abdominis

Question 2

what are the borders of supf inguinal ring

Answer 2

EO tendon form crus pelvina (lat) and crus femorale (med) (to lig. Inguinale). The slit between these tendons form the supf. Inguinal ring

First pull on leg to see lig. Inguinale. Clean area cranioprox to it to find the two crus of the EO

Question 3

what travels through anulus ing

Answer 3

• proc. Vaginalis (female, lig teres uteri)
• a./v. pudenda externa coming out of it -> trace to find Ln. Inguinalis supf.
• Ductus deferens (A/V ductus deferens)
• r. genitalis of n. genitofemoralis(L2-3)
• m. cremaster + a. cremasterica (Ex m. abd obl int)

Question 4

describe the dissection prior to dissecting a. prof. fem

Answer 4

Clean medial thigh mm. First before you transect sartorius distally to see the borders to show! Then follow ext iliac from femoral triangle

gives of a. abd caud distally to femoral canal

Becomes a. femoralis as it enters canalis femoralis (before gives off a. profunda femoris)

Question 5

what are the branches of a. prof fem

TEGN

Answer 5

goind cranial!

tr. pudendoepigastrica
- a. abd. caud
- a. epigastrica caud
- a. pudenda ext: r. epig caud sup(rr. preputiales) and r. labialis/r.scrotalis

a. circ fem med - run with n. obturatorius
- r. asc
- r. obturatorius
- r. prof
- r. acetabularis
- r. transversus ->

Question 6

which mm do you have to transect to see the branches of circ fem med

Answer 6

adductor mm and gracilis

Question 7

where do you find the lnn. ing supf

Answer 7

under branching of pudenda externa

Question 8

describe n. genitofemoralis

Answer 8

L3+L4 is the origin from pl. lumbalis: The femoral branches supplies the skin of the proximal medial thigh, nerve courses caudolaterally•The genital branches supplies skin of pudendal region •It leaves the spine through the m. psoas major, and runs along the distal part of a. iliacaexterna, before leaving the abdomen through the inguinal canal •Before leaving the abdomen, it gives off a branch to the internal oblique abdominal muscle

Question 9

n. genitofemoralis innervates

Answer 9

vulva/scrotum, prepuce, mammae, m. cremaster

Question 10

how much time for the testis to descend

Answer 10

approx 40 days

Question 11

what are the branches of iliaca externa in dog

Answer 11

deep femoral only!!

Question 12

ln - amount and other names?

Answer 12

Normally two in number Also called scrotal/mammary lymph nodes

Question 13

location of ln in female

Answer 13

In females they are underneath the inguinal mammary glands, and harder to feel.
