  1. Both plantar and dorsal interosseous muscles can be viewed for a dissection of the plantar (inferior) side of the foot. Dorsal interosseoi, but not plantar interosseoi, can be viewed from the dorsal (superior) side of the foot. This is because the dorsal interosseoi are (blank) whereas the the plantar interosseoi are monopennate.

  2. The primary "staple" to the medial longitudinal arch is the (blank) ligament. This ligament extends from the sustentaculum tali of the (blank) to the (blank) bone. Immediately superior to this ligament is the (blank) of the (blank) known as the "keystone" of the medial longitudinal arch. Immediately inferior the to this ligament is a long tendon providing a "tie-beam" for the medial longitudinal arch. This is the tendon of (blank). Another tie-beam is provided by an intrinsic muscle of the foot. This muscle is the (blank). In addition to the aforementioned muscular "tie-beams," fascial tie-beams are provided by the (blank) and even the (blank) of the sole of the foot. The major "suspension" support of the medial longitudinal arch is provided by the (blank). This muscle, in addition to suspending the arch also provides a "staple" because of the splaying out of the tendonous insertions near the base of the (blank).

  3. The (blank) provides a "staple" for the medial longitudinal arch (due to a splaying out of tendonous insertions near the (blank)), a "tie-beam" for the transverse arch, and a "suspension" for the lateral longitudinal arch.

  4. The superior aspect of the sustentaculum tali provides a site of attachment for the (blank) ligament. The anterioinferior aspect of the sustentaculum tali provides a site of attachment for the (blank) ligament. The inferior aspect of the sustentaculum tali provides a groove for the (blank). Immediately medial (superficial) to the sustentaculum tale are the (blank), (blank), and (blank). The sustentaculum tali is a bony process derived from the (blank).

  5. The dorsalis pedis has as its terminal branches the (blank) and (blank) arterys. The (blank) artery crosses the superior aspects of the base of the metatarsals whereas the other terminal branch passes inferiorly between the heads of origin of the (blank) to from the medial aspect of the (blank).

  6. The lateral plantar artery is a terminal branch of the (blank) artery. From its origin at the flexor retinaculum of the ankle the lateral plantar artery passes superior and then deep (lateral) to the (blank) muscle to enter the sole of the foot. The lateral plantar artery crosses the sole obliquely in a fascial plane immediately superior to (blank) and inferior to (blank). Upon reaching the lateral side of the sole the lateral plantar artery passes superiorly toward the base of the 5th (blank). At this location, the lateral plantar artery becomes the (blank) and lies superior to the (blank) head of the adductor hallucis and inferior to the (blank) muscles.

  7. The tendon of peroneus longus crosses the lateral aspect of the sole through an osseofibrous canal. The superior wall of this canal is the (blank). The inferior wall of this canal is the (blank).
