ATHLETIC INJURIES TEST 2

UPDATED ACTUAL EXAM WITH

CORRECT SOLUTIONS.

phalanges - correct answer- three in each toes except for the first (hallux) which has two

metatarsals - correct answer- lie between the phalanges and tarsals, one for each toe

tarsals - correct answer- there are 7 tarsal bones in the ankle

first row of tarsals - correct answer- first, second, and third cuneiforms (base of three metatarsals on the medial side of the foot) and the cuboid (lateral side of foot)

second row of tarsals - correct answer- navicular talus cakcaneus

• / 4

navicular - correct answer- articulates with the tulus and cuneiforms

talus - correct answer- most superior of all the tarsals, articulates with the calcaneus situated over a bony projection called the sustentaculum tali, also articulates with the malleolar heads of the tibia and fibula forming a mortice joint aka the talocrural joint

tibia - correct answer- medial side of the leg, principle weight bearing bone of the leg (interosseus membrane connects tibia with fibula)

fibula - correct answer- long and slender, located on lateral side, main function is to provide for the attachments of muscles

arches of foot - correct answer- absorb the shock of weight bearing, dissipate force

medial longitudinal arch - correct answer- medial border of calcaneus to the distal head of the first metatarsal (includes the calcaneus, talus, nacicular, 3 cuneiforms and the first 3 2 / 4

metatarsals), main supporting ligament is plantar calcaneonavicular ligament (spring ligament) area for "flat feet"

lateral longitudinal arch - correct answer- lateral border of calcaneus to the fifth metatarsal (includes the calcaneus, cuboid and fifth metatarsal)

anterior metatarsal arch - correct answer- distal head of all five metatarsals

transverse arch - correct answer- runs across the first row of tarsals (cuboid and cuneiforms) gives protection and increases foot's mobility

plantar aponeurosis (fascia) - correct answer- think white band of fibrous tissue from medial tuberosity of the calcaneus to proximal heads of metatarsals, supports the foot against downward forces, site of plantar fascitis

Interphalangeal (IP) Joints - correct answer- articulations of the phalanges, have one on the hallux or great toe and two on the rest (PIP and DIP) all have collateral ligaments on the medial and lateral sides and interphalangeal ligaments on the plantar and dorsal surfaces, motions include flexion and extension only 3 / 4

metatarsophalangeal (MTP) joint - correct answer- articulations of the phalanges and the metatarsals, have collateral ligaments as well as plantar and dorsal metatarsophalangeal ligaments, movements include flexion, extension, adduction, and abduction

intermetatarsal (IM) joints - correct answer- connect metatarsals at both the head (transverse metatarsal ligaments) and the base (plantar and dorsal ligaments) shafts of bones connected by interosseous ligaments

tarsometatarsal joints - correct answer- articulations of the bases of the metatarsals with the tarsal bones, connected by dorsal and plantar tarsometatarsal ligaments, movements include flexion, extension, adduction and abduction

intertarsal joints - correct answer- articulations between the tarsals, movements including gliding, flexion, extension, adduction, abduction, inversion, and eversion, the most important of these joints is the subtalar , many ligaments in the area such as the plantar calcaneonavicular
