What is the sacroiliac joint? 34. What part of the coxal bone do you sit on? 35. Is the ischial spine on the anterior or posterior side of the coxal bone? 36. If a woman has abnormally large ischial spines, why is this a problem? 37. What does the greater sciatic notch do? 38. What does the obturator foramen do? 39. What is the name of the joint where the pubic bones fuse? 40. What connective tissue will one find within this joint? 41. What is the name of the hip socket? 42. What is the difference between the true pelvis and the false pelvis? 43. Why is it important that a female’s true pelvis is wider, shallower, and rounder than a male pelvis? 44. Using the pubic arch, how can you tell if the pelvis is male or female? 45. The length of the femur is roughly what fraction of the total body length? 46. What is the weakest part of the femur? 47. Are the greater and lesser trochanters on the proximal or distal end of the femur? 48. What do the greater and lesser trochanters of the femur do? 49. Are the lateral and medial epicondyles on the proximal or distal end of the femur? 50. What do the lateral and medial epicondyles of the femur do? 51. The prefix “epi-”generally means “above”. Where are the lateral and medial epicondyles located in relation to the condyles? 52. What is the function of the condyles of the femur? 53. Where are the lateral and medial condyles of the tibia located? 54. THINK. The tibia and fibula are less flexible than the ulna and radius of the forearm. What movement can the ulna and radius do that the tibia and fibula cannot do? 55. Which bone is the shinbone? 56. What is the intercondylar eminence of the tibia? 57. Is the tibial tuberosity on the proximal or distal end of the tibia? 58. What does the tibial tuberosity do? 59. What part of the tibia do you feel as the inner ankle bone? 60. What part of the tibia do you feel as the sharp ridge of your shin? 61. The fibula does not appear to be as important as the tibia. If you did not have a fibula, would this be a problem still?
