39. Which of the following parts of the fibula is subcutaneous?
(A) Medial surface of the shaft
(B) Medial surface of the head
(C) Medial surface of the lateral malleolus
(D) Lateral surface of the lateral malleolus Correct Answers 39.
D
All the structures on the medial side of the fibula are deep. On
the lateral aspect, only the head and the lateral malleolus are
subcutaneous; the rest of the bone is covered mainly by muscle.
40. The deep plantar artery is a branch of the
(A) dorsalis pedis artery
(B) anterior tibial artery
(C) fibular (peroneal) artery
(D) lateral tarsal artery Correct Answers 40. A
The deep plantar, or first proximal perforating, artery is one of
the terminal branches of the dorsalis pedis artery.
41. Which of the following ligaments is under the greatest
tension when the foot is plantarflexed and inverted?
(A) Tibionavicular
(B) Calcaneotibial
(C) Calcaneofibular
(D) Anterior talofibular Correct Answers 41. D
The anterior talofibular ligament is oriented such that its
attachments are distracted when the ankle joint is under
inversion stress. Additional
tension is applied in plantarflexion.
,42. Which bony structure is easily palpated near the most
superior point of the medial longitudinal arch?
(A) Sustentaculum tali
(B) Navicular tuberosity
(C) First metatarsal head
(D) Fifth metatarsal tuberosity Correct Answers 42. B
Of the three structures located on bones of the medial
longitudinal arch (the sustentaculum tali, navicular tuberosity,
and first metatarsal head), the navicular tuberosity is the most
superior. It is also easily palpated through the skin.
43. The nutrient artery of the tibia is a branch of which of the
following arteries?
(A) Anterior tibial
(B) Posterior tibial concentrations.
(C) Fibular (peroneal)
(D) Popliteal Correct Answers 43. B
The nutrient artery of the tibia, a branch of the posterior tibial
artery, usually enters the bone at the nutrient foramen.
44. Which of the following features of the hip bone develops
from a secondary center of ossification?
(A) Pubic tubercle acids
(B) Iliopubic eminence
(C) Ischial spine
(D) Ischial tuberosity Correct Answers 44. D
The ischial tuberosity is one of the four fairly constant
secondary centers of ossification in the hip bone.
45. Which of the following is true of all third layer plantar
muscles?
, (A) They are toe extensors.
(B) They insert on proximal phalanges.
(C) They originate on the rearfoot.
(D) They are innervated by the lateral plantar Correct Answers
45. B
In the third layer of plantar muscles, flexor hallucis brevis and
adductor hallucis insert onto the base of the proximal hallucal
phalanx, and flexor digiti minimi brevis inserts onto the base of
the proximal phalanx of the fifth toe.
46. The primary spinal level that innervates the skin of the small
toe is
(A) L4
(B) L5
(C) S1
(D) S2 Correct Answers 46.C
The skin of the lateral side of the foot and lower leg is part of
the S1 dermatome.
47. Which of the following is the strongest ligament of the
sacroiliac joint?
(A) Sacrospinous
(B) Ventral sacroiliac
(C) Dorsal sacroiliac
(D) Interosseous sacroiliac Correct Answers 47. D
The cross-sectional area of the interosseous sacroiliac ligament
is much greater than that of the sacrospinous, ventral sacroiliac,
and dorsal sacroiliac ligaments.
48. Which of the following muscles abducts the thigh?
(A) Obturator externus
39. Which of the following parts of the fibula is subcutaneous?
