The _Peronæi_, or _Fibulæi Postici_, are otherwise call'd the _Longus_ and the _Brevis_, whereof one proceeds from the upper and almost fore-part of the _Perone_, terminating in the upper-part of the Bone, that supports the great Toe in the _Metatarsus_, and the other from the lower part of the _Perone_, adhering in like manner to the Bone with which the little Toe is sustain'd. _With what Motions are the Toes endu'd, how many Muscles have they, and which be they?_ The Toes are bent and extended, as also drawn inward and outward, by the means of twenty two Muscles, of which sixteen are Common, and six Proper. The former are two _Flexors_, two _Extensors_, four _Lumbricales_, and eight _Interossei_. The first _Flexor_ is nam'd _Sublimis_, and the other _Profundus_. The _Sublimis_ or _Perforatus_ derives its Original from the lower and inner-part of the _Talus_ and is fixt in its proper place by four cleft _Tendons_, which are inserted in the upper-part of the Bones of the first _Phalanx_ of the four Toes. It is situated under the Sole of the Feet. The _Profundus_ or _Perforans_ hath its beginning in the top and back-part of the Leg-Bone and _Perone_, slips under the _Malleolus Internus_ thro' the _Sinus Calcaris_, and makes four _Tendons_ which pass thro' the Fissures of the _Tendon_ of the _Sublimis_, and cleaves to the Bones of the last _Phalanx_ of the Toes, to bow them. The first _Extensor_ is call'd the _Common_, and the other the _Pediæus._ The _Common Extensor_, or the _Longus_, takes its rise from the top and fore-part of the _Tibia_ in the place of its joyning with the _Perone_ or {55} _Fibula_, and divides it self into four _Tendons_, which after having pass'd under the Annular Ligament, are inserted in the Articulations of every Toe. The _Pediæus_ or the _Brevis_, being plac'd over the Foot, proceeds from the Annular Ligament, and the lower-part of the _Perone_, and sends forth four _Tendons_, which are fixt to the first Articulation of the four Toes on the outside, Thus this Muscle, together with the _Longus_, causeth their Extension. The four _Lumbrical_ Muscles of the Toes arise from the _Tendons_ of the _Profundus_, and a Mass of Flesh at the Sole of the Feet. They are joyn'd by their _Tendons_ with those of the _Interossei Interni_, and adhere inwardly to the side of the first Bones of the four Toes, to incline them toward the great Toe.
