2. firmly adherent to the underlying plantar to aponeurosis
3. creased
4. hairless

WHAT ARE THE CUTANEOUS NERVES OF SOLE OF FOOT ?
- MEDIAL CALCANEAL BRANCH OF TIBIAL NERVE
- saphenous nerve
- sural nerve
- medial plantar nerve
- lateral plantar nerve
what are the dermatones on the sole of foot?
L4,L5,S1
the thickened band of superficial fascia that stretches acrosss the roots of the toes is called?
superficial transverse metatarsal ligament
deep fascia of the sole is modifies to form?
- plantar aponeurosis
- deep transverse metatarsal ligament
- fibrous flexor sheath
what are the features of plantar aponeurosis in sole of foot?
triangular
thickened part of dep fascia
morphology: detached part of plantaris tendon
morphology of plantar aponeurosis? / plantar aponeurosis represents distal part of?
plantaris
plantar apopneurosis is considered to be the distal/detached part of plantaris muscle which got seperated during evolution due to enlargemnt of heel
what are the attachments of plantar aponeurosis?
at the apex: medial tubercle of calcaneum, proximal to attachment of flexor digitorum brevis
at the base: divides into 5 processes near the head of metatarsal bones
|
|
v
each process further divides into 2 parts
| |
| |
v v
superficial slip deep slip
attached to dermis further divided into two :- one embraces flexor tendons, blending with fibours
of skin flexor sheath
one attaches with deep transverse metatarsal ligament
from margines of aponeurosis lateral and medial vertical intermuscular septa divides the sole into 3 compartments. thinner transverse septa arise from vertical speta and divide the sole into 4 layers
what are the funtions of plantar aponeurosis?
- fixation of skin of sole
- protection
- origin of attachemnts of muscles of layer 1
- maintains logitudinal arches of foot
what is a point of difference between plantar and palmar aponeurosis?
planatr gives an additional process to the great toe which restricts its movement
what are the features and functions of deep transverse metatarsal ligaments?
four short flat bands
they connect plantar ligaments of adjoining matatarsophalangeal joints
what are the attahments of deep transeverse metatarsal ligaments?
dorsally- interossei
ventrally- lumbricles+ digital vessels and nerves
function of fibrous flexor sheaths?
retain flexor tendons in position during flexion of toes
what is plantar fasciltis?
pain in heel region due to stretching of plantar aponeurosis, especially during standing
what is calcaneal spur?
small calcified bone extension on the inferior aspect of calcaneum or at site of attachment of tendo calcaneum
