PLATE XXXVII. 



MUSCLES 



A Abductor minimi digiti. 



B Flexor brevis digitorum. 



C Abductor hallucis. 



D Edge of internal annular ligament. 



E Tendon of flexor longus hallucis. 



F Tendon of flexor longus digitorum. 



G Origin of adductor hallucis from long 



plantar ligament. 

 G' Insertion of adductor hallucis. 

 H Origin of flexor brevis hallucis from 



cuboid. 

 H' Insertion of flexor brevis hallucis, 



showing its two heads. 

 K Transversus pedis (abductor trans- 



versus). 



L Plexor brevis minimi digiti. 

 M Tendon of peroneus longus. 

 M' Insertion of peroneus longus into 



internal cuneiform and first meta- 



tarsal bones, a distinct slip going to 



the second metatarsal. 

 N Plantar interossei. 

 Dorsal interossei (the numbers show 



the different muscles in both sets). 



P Long plantar ligament. 



Q Origin of flexor accessories, inner 



head. 



R Short plantar ligament. 

 S Placed over internal cuneiform on in- 

 sertion of tibialis posticus. 

 T Placed over scaphoid on tendon of 



insertion of tibialis posticus. 

 U Inferior calcaneo-cuboid or spring 



ligament. 



V Posterior edge of external cuneiform. 

 W Anterior edge of scaphoid. 

 X Slip from tendon of tibialis posticus 



breaking up for its insertion into 



tarsal and metatarsal bones. 

 Y Capsular ligament of first tarso-meta- 



tarsal joint. 

 Z Bough surface over bases of 2, 3, 4 



metatarsal bones, from which the 



abductor hallucis arose. 

 * Glenoid plates, to the edges of which 



the deep slips of the plantar fascia 



are seen attached. 



a Termination 



artery. 



b Internal plantar. 

 c External plantar. 

 d First digital. 

 e Second digital. 

 / Muscular twigs. 

 g Third digital. 



VESSELS 

 of the posterior tibial 



h Fourth digital. 



k Communicating artery from the dorsa- 

 lis pedis to complete the deep plantar 

 arch. 



I Branch from k, which in this case joins 

 the princeps hallucis, instead of 

 forming it, the princeps coming 

 directly from the internal plantar. 



NERVES 



1 Internal plantar. 



2 External plantar. 



3 Digital branches of the external plantar 



(cut). 



4 Muscular branches to the flexor brevis 



minimi digiti. 



5 To third plantar. 



6 To fourth dorsal. 



7 To second plantar. 



8 To third dorsal. 



9 To first plantar. 



10 To second dorsal. 



11 To first dorsal. 



12 Branches which gave off nerves to 



the transversus pedis and then ended 

 by passing under the glenoid plates 

 to supply the metatarso-phalangeal 

 joints.
