Answer 1

Ans-18. a. True

The obturator nerve supplies all the muscles in the medial compartment of the thigh. It enters the thigh by passing through the obturator foramen accompanied by the obturator artery. It divides into anterior and posterior branches as it goes through the obturator foramen.

Ans-19. d. Inguinal ligament

The exit point of the external iliac arteries is lateral to the insertion point of the inguinal ligament on the pubic tubercle, approximately one third the distance of pubic tubercle to the anterior superior iliac spine. Distal to inguinal ligament, the external iliac artery becomes the common femoral artery.

Ans-20. a. True

Each of the cruciate ligaments of the knee contains functionally different fiber groups, one fibre bundle is always taut, numerous other fibre bundle are taut in intermediate or extreme position. The bulk of fibres of anterior cruciate ligament are taut in maximal extension of knee while posterior cruciate ligament is taut in intermediate and maximal flexion.

21. (a).True

Bipedalism has got many advantages to primates in walking in which they have evolved to move their visceral fat to subcutaneous as an advantage.

22. (b). False

Triceps surae is a pair of muscles located at the calf - the gastrocnemius and soleus.They insert at the calcaneus .While sartorius, gracilis and semitendinosus are sometimes referred to as guy ropes.

Ans-23. (a). Rectus femoris

In the swing phase, the raised leg is propelled forward. This is where the forward motion of walk starts. Iliopsoas and rectus femoris keep the thigh flexed at hip joint, resisting gravity as it tries to pull the lower extremity down.

Ans-24. (c). Gluteus medius and gluteus minimus

The hip abductor muscles include gluteus medius, gluteus minimus and tensor fascia latae. They help in moving leg away from the body and also in rotation of leg St the hip joint.

Ans-25. (d). The foot has an elongated carpel that acts as a lever during locomotion

It is wrong because carpel bones are present in the wrist while in the food tarsels are present.
