What artery provides most of the blood supply to the lower limb?
Femoral artery which has a branch that is called the profunda femoris (providing blood supply to anterior part of the thigh) which in turn gives smaller branches to all of the muscles of the anterior thigh
The deep femoral artery has how many perforating arteries? What do they do?
4 perforating branches that provide blood supply to the posterior part of the thigh
Which artery provides blood supply to the medial part of the thigh?
Obterator artery
Where would you place a lead (catheter) into the left side of the heart, where would you place it first?
Femoral artery
If you want to place a lead (catheter) into the RIGHT side of the heart (angiography) where would you start it first?
Femoral vein (just medial to the femoral artery)
Once the femoral artery pass the abductor magnis, what artery does it became?
Popliteal artery
What are the two superficial veins that drain blood from the leg?
The great saphenous vein (medially) and the lesser saphenous vein (laterally).
TRUE or FALSE: Blood generally runs from superficial veins to deep veins.
TRUE occurs because of skeletal muscles pushing it via the musculovenous pump. If it fails, you get varicose veins.
Describe deep vein thrombosis.
Formation of blood clots in deep veins of the lower limb because of poor blood flow (stasis) or injury to the walls of veins which stimulates clotting or as a consequence of disease process causing increased coagulation of blood. Risks included post surgery immobility. The thrombus grows bigger and breaks loose (embolus) and thravels up the CV system and can block blood flow to the lungs...BAD!
Describe thromboflebitis.
Thromboflebitis is a thrombosis in a ven which leads to inflammation around the clot site within the walls of the blood vessels. Causes pain, increased temperature at site. Long periods of sitting (such as long traveling/flights) can cause this.
When you sit down, what part of what bone are you sitting on?
Your ischial tuberocity
Which two ligaments prevent anterior rotation of the vertebral column (particularly the sacral part)?
The Sacrotuberous and sacrospinous ligaments
Name the structures that pass through the great sciatic foramen between the gluteal region and pelvis.
n
Describe the structures that pass through the lesser sciatic foramen between the gluteal region and the perineum.
n
What is the function of the pelvic diaphragm?
To hold in all of the structures of the perineum.
Describe the tensor fasciae latae muscle (origin, insertion, function, etc).
n
Describe the gluetus maximus muscle (origin, insertion, function, innervation, blood supply, etc).
Function is to Stabalizes knee joint, innervation is from the superior gluteal nerve
Describe the tensor fasciae latae muscle (origin, insertion, function, innervation, blood supply, etc).
Innervation from the Inferior gluteal nerve, blood supply from inferior gluteal artery, hip extension is it's main function
Describe the gluteus medius muscle (origin, insertion, function, innervation, blood supply, etc).
n
Describe the gluteus minimus muscle (origin, insertion, function, innervation, blood supply, etc).
Function is to maintain the horizontal plane of the pelvis without support.
Describe the piriformus muscle (origin, insertion, function, innervation, blood supply, etc).
n
Describe the superior gemalus muscle (origin, insertion, function, innervation, blood supply, etc).
n
Describe the inferior gemalus muscle (origin, insertion, function, innervation, blood supply, etc).
Function is lateral rotation of the hip
Describe the obterator internus muscle (origin, insertion, function, innervation, blood supply, etc).
Function is lateral rotation of the hip
Describe the quadratus femorus muscle (origin, insertion, function, innervation, blood supply, etc).
Function is lateral rotation of the hip
The sciatic nerve is made up of which two nerves?
The tibial nerve and the common fibular nerve. They do NOT intermix at any point! They come from the sacral plexus
Describe piriformus syndrome? What are it's symptoms?
Chronic irritation and entrapment of the sciatic nerve from increased size of the piriformus muscle which causes sciatica (e.g. pain, tingling, muscle weakness down the leg, etc.)
What portion of the gluteus maximus would you want to give an injection in to avoid nerve damage?
The anterior superior portion of the gluteus maximus.
How many muscles in the anterior part of the thigh? ?What do they do? What are they innervated by?
Extend the hip and flex the knee is their function, there are 4 of them, and are innervated by parts of the sciatic nerve
What are the 3 requirements for a muscle to be considered a hamstrings muscle?
1. Proximal attachments of ischialtuberosity (cross hip joint)
2. Innervation of tibia or fibula (cross knee joint)
3. Muscle must be innervated by tibial division of sciatic nerve
What is the linea aspera?
n
