we may call the Rachitae, or Chin-muscles. Now, that hereafter we may severally and distinctly set down the Muscles of the extreme parts, we will come to the Privities.
Where for the use of the Testicles, there are two Muscles called the Cremasteres, or Hanging-muscles. At the root of the Yard, or Peritonaeum, there are four others, partly for the commodious passing of the urin and seed, and partly for erecting the yard. The Sphinct••r-muscle is seated at the Neck of the Bladder.
At the end of the right gut are three Muscles, two Levatores Ani, or Lifters up of the Funda∣ment, and one Sphincter or Shutting-muscle. Now let us prosecute the Muscles or the extremi∣ties, or limbs. But it will be sufficient to mention only the Muscles of one side, because seeing these parts of the body are double, those things which are said of the one may be applyed to the other.
Wherefore the Muscles or the Arm, beginning with these of the shoulder-blade, at the least, are 42. for there are four of the Shoulder-blade: of the Arm properly or particularly so called, seven or eight; and there are three, four, or five proper Muscles of the Cubit: that is, appoint∣ed for the performance of the motions thereof; in the inner part of the Cubit are seven, and as many in the outer; but those of the hand are reckoned thirteen at the least.
The four of the Shoulder-blade are the Trapezius, resembling a Monks Cowl, which moves it upwards and downwards, and draws it backwards; the second is the Levator, or lifter-up; the third the great Rhoimboides lying under the Trapezius. The fourth, the lesser Saw-muscle, which is inserted into the Caracoides. The Arm is moved forwards, backwards, upwards, downwards, and circularly.
The Pectoral Muscle arising from the Clavicle, Brest-bone, and neighbouring Ribs, draw it forwards; the Humilis, or Low-muscle, coming from the Lower-rib of the Shoulder-blade draws it backwards; the Delteides upwards; and the Latissimus downwards, and somewhat backwards. But the three seated about the Shoulder-blade move it about, or circularly.
The Epomis or Scapularis upwards; the Superscapularis, which may seem two, backwards and downwards; the Subscapularis which is in the Cavitie of the Shoulder-blade, forwards, so that by a certain vicissitude and succession of action, they move it circularly. Two Muscles bend the Cubit, the one named Biceps, or two-headed, and the other Brachiaeus or the Arm-muscle; but one, two, or three Muscles extend it; for, if you have respect to the original, this muscle hath two or three heads, but one only insertion.
In the inside of the Cubit are seven Muscles, one Palmaris, two Wrist-benders; two Pronatores, one square, another in some sort round; two finger-benders, and one Abductor, or Drawer aside. These fourteen internal and external Muscles of the Cubit, do not indeed move the Cubit, but only seated there move the Wand, and with it the Hand. These are the thirteen Muscles of the Hand; the Thenar which may not only be divided into two, but into six, not only by the divers actions it performs, but also by the branches divided by a manifest space between them; the se∣cond is called the Hypothenar, which lies under the little finger, as the Thenar doth under the Thumb; the third is the Abductor of the Thumb; then follow the four Lumbrici and six Interosses, although eight may be observed.
The whole Leg hath at the least 50 Muscles, for we reckon there are fourteen Muscles in the Thigh, there are eleven made for the use of the Leg; there are nine seated in the Leg, three be∣fore, and six behind, which serve for the use of the Foot and Toes; in the Foot are seated sixteen. Therefore of the fourteen muscles serving the Thigh to bend it, one called the Lumbaris, the other arising from the cavity of the Hanch-bone; but the three which make the Buttocks and the Triceps or Three-headed Muscle, (which, if you please, you may divide into three) extend it. Besides these, the four Twin-muscles, and two Obturatores, of which the one is internal, and the other external, turn the Thigh about. The Leg hath eleven; that is, the long, the membra∣nous, the four Postici, or Hind-muscles (three of which come from the Huckle-bone, but the other from the commissure of the Share-bone) the right, the two vast, the Crureus or Leg-muscle, and the Popliteus, or Ham-muscle. These seated in the Leg for the use of the Foot and Toes, are three fore, and six hind-muscles: two of the fore bend the Foot, one of which is called the Tibiaeus an∣ticus, the other Peronaeus, which you may divide into two. The third the bender of the Toes, al∣though it also partly bend the foot, to which also the bender of the thumb may be revoked. One of the hind is the Toe-benders, others extend the foot; and are in this order: two Twins, one Plantaris, one Soleus, one Tibiaeus posticus, and the great bender of the Toes, to which may be re∣voked the bender of the Thumb. Of the sixteen seated in the foot, one is above, seated on the back of the Foot, which we call the Abductor of the Toes; another, in the sole of the Foot; to wit, the little bender of the Toes, which goes to the second joynt of the Toes alongst the inside of the foot; the other lends his help to the great Toe, which you call the Abductor of the Thumb; another is seated on the outside for the use of the little Toe. To these are added the four Lumbri∣ci, besides the eight Interosses, or if you had rather, ten. And thus much may suffice for the en∣numeration of the Muscles.
