Muscles and Tendons Of LL

Question 1

Explain the function of muscles of the gluteal region

Answer 1

Extension/flexsion and abduction of hip

Gluteus maximums (superficial)
Gluteus mediums and minimus
Deep gluteal muscles
Piriforms 
Iliopsoas (main flexsion at hip)

Question 2

Name and explain the function of muscles around the thigh

Answer 2

Divided into 3 sections

Anterior: flexsion of hip and extension of knee. (Femoral nerve)
- quadriceps femoris group

Posterior: extension of hip and flexsion of knee (sciatic nerve)
- hamstrings

Medial: adduction of hip (obturator nerve)
- adductor group

Question 3

Name and explain the function of muscles in the leg

Answer 3

Divided into three groups

Anterior: dorsiflexsion at ankle, inversion of foot, extension of toes (deep peroneal nerve)

• tibialis major
• extensor hallucus longus (big toe)
• extensor digitorium longus

Lateral: plantarflexsikn of ankle, eversion of foot (superficial peroneal nerve)
- fibularis longus and brevis

Posterior: (tibial nerve) divided into 2
- superficial (plantar flexsion ankle) =
gastrochemius,
soleus

• deep (plantar flexsion ankle, flexsion of toes) =
  Tibialis posterior
  Flexor digitorium longus
  Flexor hallucus longus

Question 4

What’s the name of the plexus for the lower limb?

Answer 4

Lumbar plexus and lumbosacral plexus

L1-4 = lumbar plexus (anterior and medial thigh)

L4-S2 = (remaining muscles of thigh)

Question 5

Name the nerves that supply her lower limb

Answer 5

Lumbar plexus

• femoral
• obturator

Lumbosacral
- sciatic (which branches into tibial and peroneal)

Question 6

Explain the order of arteries thst supply blood to the lower limb

Answer 6

Abdominal aorta 
External iliac artery 
Femoral artery 
Popliteal artery 
Anterior and posterior tibial artery 
Dorsalis pedis artery

Question 7

Distinguish the order of the veins that take blood back to the heart from lower limb

Answer 7

Deep veins

• dorsal Venus plexus
• anterior + post. Tibial vein
• poplitersl vein
• femoral vein
• external iliac vein
• IVC

Superficial veins (these drain into the deep veins)

• great saphenous vein = femoral vein
• lesser saphenous vein = popliteal vein
