What regions of the pelvic limb make up the buttocks?
What about the lower leg between the knee and tarsus? |
The gluneal and cluneal regions make up the buttocks. The crural region is the lower leg.
|
|
|
Which region of the pelvic limb is the knee?
The caudal knee? |
The genicular and popliteal, respectively.
|
|
|
What are the twelve regions of the pelvic limb?
|
Sacral
Gluteal Cluneal Femoral - thigh Patellar Genicular Popliteal Crural Calcanean Tarsal Metatarsal Phalangeal |
|
|
Which species is the sacrotuberous ligament present in, the dog or the cat?
Where does it course from and what four muscles does it serve as an attachment site for? |
The dog
Courses from the transverse processes of the last sacral and first caudal vertebrae to the lateral angle of the ischiatic tuberosity Serves as a site of attachment for the following muscles: Biceps femoris m. Superficial gluteal m. Piriformis m. Abductor cruris caudalis m. |
|
|
Which three pelvic limb muscles make up the hamstring?
|
Biceps femoris, semitendinosus, and semimembranosus mm.
|
|
What is the origin/insertion/innervation/action of biceps femoris m.?
|
Origin:
Ischiatic tuberosity; sacrotuberous ligament (dog) Insertion: Patella via fascia lata and crural fascia, cranial border of tibia, tuber calcanei via common calcaneal tendon Innervation: Sciatic n. (Cranial portion – caudal gluteal n.) (Caudal portion – tibial n.) Action: Abduct and extend the limb (whole muscle - the pee pee muscle) Extend the hip and stifle (cranial part) Flex the stifle (caudal part) Extend the tarsus (common calcaneal tendon) When the limb is fixed on the ground, produces a powerful thrust on the trunk |
|
|
Which muscle allows dogs to lift their leg to pee?
|
The biceps femoris m.
|
|
What is the origin/insertion/innervation/action of semitendinosus m.?
|
Origin:
Ischiatic tuberosity Insertion: Medial surface of the body of the tibia, tuber calcanei via common calcaneal tendon Innervation: Sciatic n. Action: Extend the hip Flex the stifle Extend the hock |
|
What is the origin/insertion/innervation/action of semimembranosus m.?
|
Origin:
Ischiatic tuberosity Insertion: Distomedial femur, proximal tibia Innervation: Sciatic n. Action: Extend the hip Extend the stifle Flex the stifle |
|
|
What pelvic muscle is a common site for IM injections in horses?
|
The semimembranosus m.
|
|
What is the origin/insertion/innervation/action of the caudal crural abductor m.?
|
Origin:
Dog – Ischiatic tuberosity, sacrotuberous ligament Cat – Ca 1 or Ca 2 Insertion: Crural fascia Innervation: Sciatic n. Action: Abduct the pelvic limb (but of course, it's not the main abductor biceps femoris is). |
|
What is the origin/insertion/innervation/action of the sartorius m.?
|
Origin:
Dog Cranial part - Iliac crest, thoracolumbar fascia Caudal part - Iliac spine, ventral border of the ilium Cat Iliac crest, wing of the ilium Insertion: Cranial part – patella Caudal part (and cat insertion) – cranial border of the tibia Innervation: Femoral n. Action: Flex the hip Extend the stifle |
|
What is the origin/insertion/innervation/action of the gracilis m.?
|
Origin:
Pelvic symphysis Insertion: Cranial border of the tibia, tuber calcanei Innervation: Obturator n. Action: Adduct the pelvic limb Flex the stifle Extend the hip Extend the hock |
|
What is the origin/insertion/innervation/action of the pectineus m.?
|
Origin:
Iliopubic eminence and pubic tubercle via the prepubic tendon Insertion: Distal end of the medial lip of caudal rough face of the femur Innervation: Obturator n. Action: Adduct the pelvic limb |
|
What are the origin/insertion/innervation/action of adductor magnus et brevis and longus mm.?
|
Origin:
Pelvic symphysis, ischiatic arch, ventral pubis, ischium Insertion: Lateral lip of caudal rough face of the femur Innervation: Obturator n. Action: Adduct the pelvic limb Extend the hip |
|
|
What are the boundaries of and structures located within the femoral triangle? What structure do these vessels course through to get to the limb?
|
Boundaries:
Proximal – inguinal ligament Cranial – sartorius m. (caudal belly) Caudal – pectineus m. Medial – medial femoral fascia Lateral – iliopsoas and vastus medialis mm. Structures located within the femoral triangle: Femoral a. Femoral v. Saphenous n. They course through the vascular lacuna. |
|
|
Where does the popliteal ln. drain to?
|
The popliteal (8) drains to the femoral (9) ln.
