small animal pelvic vessles and nerves

Question 1

Answer 1

Question 2

Femoral Triangle

boarders

stuff

Answer 2

• The femoral artery passes through the triangle.
• distal caudal femoral artery branches at level of stifle
• femoral artery transitions to popliteal artery after that

Answer 5

Question 6

medial saphenous

Answer 6

medial saphenous

used for veinupuncture in cats

Question 7

Nervous supply of pelvic limb

Answer 7

nervous supply of pelvic limb

• lumbosacral plexus= voluntary and sensory
  *

Question 8

obturator nerve

Answer 8

obturator nerve= adductor muscles

• external obturator m.
• pectineus m.
• gracilis m.
• adductor m.

Question 9

Femoral nerve

Answer 9

Femoral nerve= stifle extension, hip flexion, support

• iliopsoas m
• quadriceps mm

** exits the belly of the iliopsoas m. causally

Question 10

Sciatic nerve

2 branches too

Answer 10

Sciatic nerve= flexors of stifle and extensors of hip

• biceps femoris m.
• semitendinosus m.
• semimembranosus m.

**travles distally caudal to the femur. (lateral side of adductor m.)

Sciatic branches into

• tibial nerve= caudal plantar aspect
  
  • gastroc
  • SDF
  • popliteus
  • DDF
• common peroneal nerve (aka fibularis)=cranial dorsal aspect! splits into…
  
  • deep peroneal
  • superficial peroneal
    
    • cranial tibial
    • peroneus longus
    • LDE

Question 11

Pes innervation

Answer 11

pes= foot

** clinical relevence- nerve blocks

• dorsl aspect= common peroneal nerve
• plantar aspect= tibial nerve
  
  • travles through tarsal tunnle

Question 12

stifle innervation

Answer 12

stifle innervation

• femoral nerve
  
  • saphenous n.
• sciatic nerve
  
  • tibial nerve
  • common peroneal n.

Question 13

Autonomous vs. Cutaneous Zones

Answer 13

Cutaneous Zone

• entire area innervated by a nerve

Autonomous zone

• the area innervated by that nerve that is ONLY innervated by that ONE nerve
