1

tuber coxae and ischiatic tuberosity

indicate the slope of the pelvis

2

greater trochanter of the femur

marks the position of the hip joint; hip joint is medial and ventral to greater trochanter

3

what bursa is associated with the tendon of the accessory gluteal muscle

trochanteric bursa

4

biceps femoris

Cd and sacral vertebrea sacrosciatic ligament and ischiatic tuberosity

5

semitendinosus

Cd and sacral vertebrea sacrosciatic ligament and ischiatic tuberosity

6

sacrosciatic ligament

sheet of strong connective tissue that completes the wall of the pelvis latearlly; arises dorsally from lateral border of the sacrum and transverse processes of first two cd vertebrea extends to ischial spine and tuber; leaves an opening between the latter two points is the lesser sciatic foramen; the greater sciatic foramen; cd border of sacrosciatic ligament is free and corresponds to sacrotuberous ligament to dog

7

nerves of the sacral plexsus

ventral branches of sacral nerves, sciatic nerve, cranial and caudal gluteal nerve, caudal cutaneous femoral nerve, pudendal and caudal rectal, pelvic nerve

8

ventral branches of sacral nerves

lies on both surfaces of the sacrosciatic ligament

9

sciatic nerve

large; passes caudoventrally over gluteus profundus to disappear cd to hip jt; runs between ischiatic tuberosity and greater trochanter

10

caudal gluteal nerve

arises from dorsal border of sciatic nerve and supplies superficial gluteal and proximal part of biceps; arises with caudal cutaneous femoral nerve which is smaller

11

caudal cutaneous femoral nerve

arises with caudal gluteal nerve from dorsal border of sciatic passes caudoventrally and sends branch to semitendinosus and continues to cd surface of the thigh

12

nerves traveling medial to sacrosciatic ligament

pudendal nerve (cranially) and caudal rectal nerve (caudally)

13

nerves traveling lateral to sacrosciatic ligament

sciatic nerve, caudal gluteal nerve, which arises with smaller caudal cutaneous femoral nerve

14

coccygeus

arises from apponeurotically from ischial spine and inserts on first few cd vertebrea and deep caudal fascia; lateral to levator ani

15

levator ani

medial/ ventral to coccygeus; arises apponeurotically from ischial spine and inserts on and around anal canal

16

cr gluteal nerve innervates

adductor, tensor fasciae latae, superficial gluteal, middle gluteal, deep gluteal

17

caudal gluteal nerve innervates

superficial gluteal, vertebral head biceps femoris, vertebral head of semitenddinosus

18

sciatic nerve innervates

pelvic head biceps femoris, pelvic head semitendinosus, semimembranosus

19

pudendal nerve

from S[2]3-S4
sensory to rectum, perineal skink internal and external reproductive organs and motor to much of striated perineal musculature; skin of anus, vulva, and ventral perineal region; ventral part striated musculature of perineum, branches of skin of prepuce and scrotum and cd part of udder

20

caudal rectal nerve

supply sensory fibers to rectum, anus, and perianal skin and motor fibers to dorsal perineal striated musculature including elevator ani

21

caudal cutaneous femoral nerve

skin over cd aspect of thigh

22

pelvic landmarks

tubercoxae (most cr), tuber sacrale (most dorsal), ischiadic tuberosity (v and most cd)

23

femur landmarks

greater (most cr; lateral), lesser (medial), and 3rd trochanters (small mid dorsal femur, lateral)

24

vessels associated with sacrosciatic ligament

med- cd gluteal artery, int pudendal artery, cd rectal artery
