Cross sections of right foot
Section of foot through tarsometatarsal joints, viewed from in front
The plane of section passes through the bases of all of the metatarsals and portions of the three cuneiform bones. Several interosseous ligaments (6, 8, 18) are visible. The potential fascial spaces between layers of muscle in the central compartment of the foot have been emphasized by pulling the muscles slightly apart from each other.
1 . Upper pointer: Intermediate cuneiform bone Lower pointer: 1st metatarsal bone
2 . Extensor digitorum longus muscle (tendons covered by fascia of dorsalis pedis)
3 . Lateral cuneiform bone
4 . 2nd metatarsal bone
5 . Extensor digitorum brevis muscle
6 . Metatarsal interosseous ligament
7 . 5th metatarsal bone
8 . Metatarsal interosseous ligament
9 . Interosseous muscle
10 . 5th metatarsal bone
11 . Abductor digiti minimi muscle
12 . Flexor digiti minimi muscle
13 . Lateral plantar artery and vein
14 . Lateral intermuscular septum
15 . Lateral plantar nerve
16 . Extensor hallucis longus muscle (tendon)
17 . Medial cuneiform bone
18 . Cuneometatarsal interosseous ligament
19 . Tibialis anterior muscle (tendon inserting on 1st metatarsal)
20 . metatarsal bone
21 . Peroneus longus muscle (tendon)
22 . Abductor hallucis muscle
23 . Flexor hallucis brevis muscle
24 . Flexor hallucis longus muscle (tendon)
25 . Oblique head of adductor hallucis muscle
26 . Medial plantar nerve
27 . Flexor digitorum longus muscle (origins of lumbrical muscles visible medial to pointer fibers of insertion of quadratus plantae faintly visible lateral to pointer)
28 . Flexor digitorum brevis muscle
29 . Plantar aponeurosis
