Foot Flashcards
Bones of foot;
-7 tarsal bones
The circus need more interesting less clouns
1-talus
2-calcaneus
3-navicular
4-cuneiform(medial, intermediate, lateral)
5-cuboid
Bones of foot;
Phalanges;
3 in each digit;
2 in the big toe.
Parts of foot

Deep fascia of the foot is ——- on dorsal surfaces
And ——— on plantar surface (sole) of the foot
- Thin
- thick
Deep fascia of the foot is thick on the plantar surface
(sole) of the foot; especially at
the central part called,
plantar
aponeurosis.
DEEP FASCIA OF THE FOOT
Is triangular in shape and apex
is attached to————-.
calcaneus
Distally, plantar aponeurosis
———-at the bases of the toes
into 5 slips.
Divides
Dorsal surface of the foot consists of:
- 2 muscles;
- Extensor digitorum brevis and
- Extensor hallucis brevis.
- Dorsal is pedis blood vessels
- Deep peroneal nerve
Plantar surface of the foot consists of:
- 20 short (intrinsic) muscles of the foot;
* Medial and lateral plantar blood vessels and nerves.
Muscles on the plantar aspect are arranged in
4 layers
DORSAL ASPECT
Muscles
2 muscles
-extensor digitorum brevis
Extensor digitorum brevis arises from the upper surface of ———-and deep surface of ——————-
- calcaneus
- inferior extensor reticulum
Extensor digitorum brevis passes —— across the dorsum of the foot and gives off
- Obliquely
- 4tendons to medial 4toes
Each tendon inserts into the base
of the
proximal phalynx.
The tendon to the great toe is also
known as:
extensor hallucis
brevis.
Extensor digitorum brevis and extensor hallucinations brevis are supplied by
Deep peroneal nerve
First layer of the plantar surface
3 muscles
1) abductor hallucis
2) flexor digitorum brevis
3) abductor digiti minimi
second layer of planter surface
2 muscles and 2tendons
1) quadratus plantae
2) Lumbricals(4)
3) flexor digitorum longus tendons
5) flexor hallucis longus tendon
Third layer of planter surface
3 muscles
1) flexor hallucis brevis
2) flexor digiti minimi brevis
3) adductor hallucis
- transverse and
- oblique heads
Fourth layer of planter surface
2muscles + 2tendons
1interossei PAD, DAB
2)peroneus longus tendon
3)tibialis posterior tendon
