Q 1...Flexion of knee is preserved because sartorius and gracilis are still intact. Q 2....The arterial supply of sciatic nerve consists of many arteries,,inferior gluteal artery,lateral circumflex femoral artery, first,second and third perforators from profunda femoris . So, we can say that the origin of this arterial supply is external and internal iliac arteries . This is very important for surgeons because this variety in arterial supply helps to prevent nerve ischemia after operations. When we sit for a long time in a place,I think that we make compression to the arteries that supply the sciatic nerve , so the nerve won't receive appropriate nutrition so it won't function properly leading to numbness.

Interactive questions :
1. The patient can still produce some flexion of the leg because of the action of sartorius muscle ( which supplied by nerve to sartorius the muscular branch of anterior division of the Femoral nerve and passed the knee joint ) and gracilis muscle ( which supplied by muscular branch of anterior division of obturator nerve and passed the knee joint ) " these muscles can do flexion of the knee joint "
2. The sciatic nerve has a segmental arterial supply by branches of the inferior gluteal artery ( its origin from the internal iliac artery ) , medial circmflex femoral artery ( its origin from Deep femoral artery ) , and perforating arteries of the thigh (usually the first and second) , when we sit for a long time without moving from place to another we make compression to these arteries and their origins and as a result thehe nerve will not be able to obtain blood and nutrition and will not be able to perform its function well and that cause numbness ( this nerve provides sensory innervation to the skin of the foot and the lower leg " except for the medial leg which is innervated by the saphenous nerve "

The reason why there wasn't a complete loss of flexion of the hip and rather just weakness is the presence of the sartorius and the gracilis muscles that can still produce flexion and they are not supplied by the sciatic nerve (Sartorius----Anterior division of the femoral nerve Gracilis-------obturator nerve)

Q1: paralysis of hamstring muscles as they are supplied by the nerve and weak flexion of leg at knee joint as hamstring muscles are the major muscles responsible for flexion of knee joint However, there are 2 extra muscles ( sartorius and gracilis ) that arenโt supplied by the sciatic nerve thus not paralyzed and can continue performing their action ( flexion of knee joint)
Q2: Arterial supply of nerve is by the inferior gluteal artery and cruciate anastomosis around back of thigh where inferior gluteal artery is a large terminal brach of anterior division of internal iliac artery. Sitting for a long time without moving will apply pressure on inferior gluteal artery that innervate sciatic nerve also , we sit on the ischium where sciatic nerve runs applying pressure to it this will lead to feeling of tingling, numbness and loss of sensory cutaneous of leg , foot except medial side which is supplied by saphenous nerve for short period of time. This sensation will fade away within a few mins after moving or standing

Q2) the arteries supplied the sciatic n are inferior gluteal artery, medial circumflex femoral artery and perforating arteries
Q1: as the hamestring muscles are not the only muscles that cause flexion of the leg so their paralysis will lead to weakness of flexion of leg not loss of it. Other muscles that cause flexion of knee are sartorius & gracilis muscles that are not innervated by sciatic nerve so theri action will not be affected by its injury
Q2: nutrient arteries of the sciatic nerve are branches from inferior gluteal artery, medial circumflex femoral artery, perforating and popliteal arteries.. Someone answered them in details in comments
Their Medical imporatnce is that the obstruction of the nutrient arteries to the sciatic nerve will lead to neuropathy which means dysfunction of sciatic nerve leading to weakness of flexion of knee and extension of hip also loss of sensation over the whole leg and foot except the medial part of them till the base of the big toe as this area is supplied by saphenous vein

A 28 year old basketball player falls while rebounding and is unable to run and jump. On physical examination, he has pain and weakness when extending his thigh and flexing his leg. Which muscle involved in both movements is most likely injured?
The answer was "semitendinosus muscle" ..
Why?!
Why didn't we say biceps femoris muscle?!
According to my knowledge all hamstrings muscles do extension of thigh and flexion of the leg and biceps femoris is the most powerful muscle in the posterior compartment " I think " ...
@@Dr.Ayman_khanfour Sorry, I got the question with no choices..
But do I understand from this that if the biceps femoris is presents, we will choose it?!
Also, according to my information, we first look at the superficial and lateral muscles, because they are susceptible to injury before other muscles..
Right?!
This means if we are faced with a question like this with no choices, we will put all the possible choices and start reducing them until we arrive at the most accurate choice...
