97
Q

anterior border (tibia)

101
Q

lateral malleolus (fibula)

forms the lateral bulge of the ankle and articulates with the talus bone of the foot

102
Q

tarsus

A

posterior half of the foot, contains seven bones called tarsals

103
Q

talus

A

”"”ankle””, articulates with the tibia and fibula superiorly, carries weight of the body primarily (with calcaneus)”

104
Q

calcaneus

A

”"”heal bone””, forms heel of the foot, carries weight of the body primarily (with talus)”

105

Q

sustentaculum tali

A

”"”supporter of the talus”” aka talar shelf, medial, shelf-like projection of the calcaneus”

108
Q

metatarsus

A

consists of five small long bones called metatarsals, numbered I-V beginning on the medial side of the foot

109
Q

medial longitudinal arch

A

curves well above the ground, the talus near the talonavicular joint is the keystone of this arch which originates at the calcaneus rises to the talus and then descends to the three medial metatarsals

110
Q

lateral longitudinal arch

A

very low, elevates the lateral edge of the good just enough to redistribute some of the body weight ot the calcaneus and some to the head of the fifth metatarsal (that is, to the two ends of the arch), the cuboid bone is the keystone of this lateral arch

transverse arch

A

two longitudinal arches serve as pillars, runs obliquely from one side of the foot to the other following the line of the joints between the tarsals and metatarsals

112
Q

hip dysplasia

A

aka congenital dislocation of the hip, either the acetabulum fails to form completely or the ligaments of the hip joint are loose, so the head of the femur tends to slip out of its socket
