```
76
intrinsic dorsum foot muscles innervated by
Deep Fib N.
77
Tibial N. enters the foot via
Tarsal tunnel
78
as it passes onto the plantar foot it first gives off
medial calcaneal branches to supply the skin of the heel
79
at the medial plantar calcaneus the tibial nerve then
splits between the 1st and 2nd layers of muscle
80
it splits into
medial and lateral plantar nerves
81
Medial Plantar Nerve cords
S2-S3
82
Medial Plantar Nerve innervates
ABductor hallucis
| flexor Digitorium brevis
83
Medial Plant gives off
branches to the skin of the plantar foot
84
Medial Plant also supplies a proper
plantar digital nerve to the medial side of the big toe
85
a branch of the proper plantar digital nerve supplies
flexor hallucis brevis
86
the Medial Plant divides into
three common plantar ditigial nerves
87
the first common plantar digital nerve supplies
the 1st lumbercal
88
Lateral Plantar N. cords
S2-S3
89
Lateral Plant travels across
| and emerges
the lateral plantar foot and emerges between the flexor digitorum and Quadratus plantae
90
Lateral Plant nerve supplies
Quadratus Plantae
| ABductor digiti minimi brevis
91
Lateral Plant nerve then divides into
Superficial branch of Lateral Plant Nerve
| Deep branch of Lateral Plant Nerve
92
Superficial branch of Lat Plant N. supplies
Flexor Digiti minimi brevis
| 3rd plantar/4th dorsal interossei
93
it also supplies cutaneous to
lateral plantar foot
94
it then divides into
two digital branches
95
these two digital branches are
a proper plantar digital nerve to the skin of lateral side of little toe
and common plantar digital nerves
96
Deep branch of Lateral Plant nerve travels with
plantar arterial arch across plantar foot lateral to medial along bases of metatarsals
97
Deep branch of lateral plant nerves sends muscular branches to
remaining interossei
lateral 3 lumbercals
and ADDuctor Hallicus
98
nerve to the subtalar joint
branches of Deep Fibular N.
99
