DEEP FASCIA OF THE PLANTA OF THE FOOT

Question 1

The deep fascia of the plantar aspect of the foot is the _____?

Answer 1

plantar fascia or plantar aponeurosis

Question 2

It is a very strong, thick layer of dense connective tissue that attaches to the
plantar skin and bones of the foot, and provides partial attachment for some of the muscles of
the plantar aspect of the foot

Answer 2

deep fascia of the plantar aspect of the foot

Question 3

• the thinnest part of the plantar fascia
• attaches bone to deep fascia
• septae pass to skin along this course and contain the fat pad

Answer 3

Medial Band / Medial Slip / Medial Part of Plantar Fascia

Question 4

• attaches bone to bone

- septae pass to skin along this course and contain the fat pad

Answer 4

Lateral Band / Lateral Slip / Lateral Part of Plantar Fascia

Question 5

• the thickest and strongest part

- attaches bone to bone and bone to skin

Answer 5

Central Band / Central Slip / Central Part of Plantar Fascia

Question 6

• the thinnest part of the plantar fascia

Answer 6

Medial Band / Medial Slip / Medial Part of Plantar Fascia

Question 7

• the thickest and strongest part

Answer 7

Central Band / Central Slip / Central Part of Plantar Fascia

Question 8

what are the two layers that comprise the distal attachments of the central band of the plantar fascia?

Answer 8

superficial and deep layers of the central band

Question 9

name this layer of the central band?

• most plantar, septae pass to skin along their course and contain the fat pad
• attaches bone to skin

Answer 9

superficial layer of the central band

Question 10

name this layer of the central band?

• splits into medial and lateral slips that pass along either side of the long and short flexor tendons creating the flexor sheaths

Answer 10

deep layer of the central band

Question 11

name this component of the superficial layer

• attach to the skin of the sulcus between the toes and the forefoot

Answer 11

Longitudinal Fibers of Superficial Layer

Question 12

name this component of the superficial layer

• transverse fibers arise near the skin attachment at the sulcus and
  course from one digital band to another forming the superficial transverse metatarsal ligament at the level of the
  metatarsophalangeal joints

Answer 12

Transverse Fibers of Superficial Layer

Question 13

• transverse fibers arise near the skin attachment at the sulcus and course from one digital band to another forming the _____?

Answer 13

superficial

transverse metatarsal ligament at the level of the metatarsophalangeal joints

Question 14

this is what part of the deep layer of the central band?

attach to the proximal phalangeal bases at the medial tubercles, respectively, ex. the 2nd band attaches to the medial proximal phalangeal base of the 2nd toe

• at the 1st metatarsophalangeal joint, these slips attach to the
  respective sesamoid, too

Answer 14

Medial Slips

Question 15

this is what part of the deep layer of the central band?

attach to the lateral tubercles of the base of the proximal phalanx of the respective digit, ex. the 3rd band attaches to the lateral proximal phalangeal base of the 3rd toe

Answer 15

Lateral Slips

Question 16

this is what part of the deep layer of the central band?

• fibrous tunnels that protect the long and short flexor tendons
• formed as the slips blend with surrounding structures

Answer 16

Flexor sheaths

Question 17

dorsal border of the flexor sheath

Answer 17

deep transverse metatarsal ligament

Question 18

plantar border of the flexor sheath

Answer 18

superficial transverse metatarsal ligament

Question 19

medial border of the flexor sheath

Answer 19

medial slip of deep layer of central band of plantar aponeurosis for the respective toe

Question 20

lateral border of the flexor sheath

Answer 20

lateral slip of deep layer of central band of plantar fascia for the respective toe

Question 21

• a thickening of the plantar aspect of the capsule and the plantar
  metatarsophalangeal ligament of the metatarsophalangeal joints that serves as a site of attachment for the deep transverse metatarsal ligament
• 1st metatarsophalangeal joint plate is less thick due to the presence of sesamoids

Answer 21

Plantar Plate / Volar Plate
