- c) has blood supply solely from the inferior gluteal artery
- d) is the chief control of hip flexion

Not 100% certain this is right but all others are wrong (as per Moores - ‘the inferiorn edge…is located just superior to the gluteal fold’)
As per Moores, ‘some’ fibres insert into the gluteal tuberosity, but this is only a portion of the smaller, deep portion and unlikely 50%
Blood supply is superior and inferior gluteal arteries
Acts as hip extension and lateral rotation (although is not generally used to stable walking or standing - just if power is needed or walking uphill/steps)
Has three bursae - trochanteric, ischial, and gluteofemoral

- a) sciatic nerve
- b) nerve to obturator internus
- c) superior gluteal nerve
- d) pudendal nerve
- e) posterior femoral cutaneous nerve
c) superior gluteal nerve
- This is the given answer, likely because the others all enter inferior to piriformis and this enters superior to it (Piriformis noted to be an important landmark for the region so things are likely to be related to that around here)*
- Alternatives are pudendal as it is the only one entering the lesser sciatic foramen etc, but given the importance of piriformis, think piriformis first.*

- e) the long head of biceps arises from the lateral facet of the ischial tuberosity
b) ischial fibres of adductor magnus degenerate to form the tibial collateral ligament
- This is the answer given - I cannot find information in Moores. Ischial fibres are the hamstring portion which insertions into the adductor tubercle and neither words nor pictures suggest there is continuity between it and the TCL. I would hazard a guess at e)*
e) the long head of biceps arises from the ischial tuberosity (moores does not specify where, but looks to be on the lateral aspect in pictures) - a) the cutaneous nerve supply is from the inferior cluneal nerves superioly, and the posterior cutaneous nerve of thigh distally
- c) semitendinosus lies superficial to semimembranosus
- d) the oblique popliteal ligament is an expansion of semimembranosus

- a) lies postero**lateral and inferior to tensor fascia latae (judging by pictures)
- b) inserts onto the anterolateral tubercle of tibia
- c) is the origin of 60% of gluteus maximus
- Gluteus maximus primarily inserts into the ITB, but a specific percentage is not given
- d) cannot flex the knee due to its attachement to the femur/intermuscular septum of thigh, so it does not have the necessary freedom. It does stabilise the knee though.

- a) anterior cruciate ligament
- b) oblique popliteal ligament
- c) medial collateral ligament
- d) lateral collateral ligament

Not specifically mentioned in the Moores, but a quick google search says ‘the cruciates tighten’, without being more specific

- b) inserts into the second metatarsal bone
- c) is pierced by the posterior tibial artery
- d) tendon is deep to the superior extensor retinaculum
- e) does not arise from the interosseous membrane

- d) the posterior cruciate ligament is attached to the lateral condyle of the femur
- e) the cruciate ligaments are sensitive and the menisci are not
a) the fibular collateral ligament is not attached to the lateral meniscus and joint capsule - seperated by popliteus
Changed wording of question as none seemed right - initially e) given as correct but this seems wrong
- b) there is one main gap in the capsule, for tendon of popliteus, and 4 bursae that communicate with the joint
- c) the tibial collateral ligament is tight in extension (same for all ligaments - hence this is the position of joint stability)
- d) the posterior cruciate ligament is attached to the medial condyle of the femur
- Antero->lateral - postero->medial
- e) the cruciate ligaments are sensitive and the menisci are not
- Innervation of specific ligaments not mentioned in Moores, but this seems wrong (ie a ruptured ACL can be painless, but meniscal tears are painful - speaking from experience).
16) Regarding nerve supply of the lower limb:

- d) the sciatic nerve does not make contact with bone
- e) the tibial part of the sciatic nerve is the sole supply to hamstring muscles
e) the tibial part of the sciatic nerve is the sole supply to muscles in the hamstring compartment
Confusing wording - I have changed it in the question but left original above, to try and get a learning point across. All hamstring muscles are supplied by the Tibial nerve (as per Moores this is a common feature of them), but shorthead of biceps is supplied by common fibular, which is technically not a hamstring, but they could be referring to posterior thigh as the ‘hamstring compartment’, a term I havent heard before. This seems most correct based ln current textbook.
b) the cruciate ligaments are supplied by the tibial nerve
This was given as correct: not mentioned in Moores, but google search seems to confirms it. femoral, tibial, and common fibular supply the anterior, posterior, and lateral aspects respectively - the cruciates are seperated from the joint cavity by a reflection of the synovial membrane, leaving them exposed posteriorly. I wouldn’t dwell on this point as not in the prescribed text.
- a) deep fibular nerve supplies the muscles in the anterior compartment of the leg
- c) the obturator nerve supplies obturator externus muscle
- internus is supplied by nerve to obturator internus off the sacral plexus
- d) the sciatic nerve does make contact with bone
- ’..rests on the ischium and then passes posterior to obturator internus, quadratus femoris, and adductor magnus’

- c) the medial two tendons receive a strong slip from the tendon of flexor hallucis longus
- d) the tendons have flexor sheaths
- e) it inserts into the bases of the middle phalanges
d) the tendons have flexor sheaths
Have altered question stem (initially had ‘no’ flexor sheaths as a wrong answer) because the answer given as correct (below) does not appear in Moores at all.
c) the medial two tendons receive a strong slip from the tendon of flexor hallucis longus
Moores states that Quadratus Planae gives slips to FDL, no mention made of tendon of FHL giving slips to anything.
- a) its four tendons divide under the sole of the foot
- b) it arises from the tibia, interosseous membrane, and a broad tendon to fibula
