The Explication of the Figures.
The First Figure
SHews a simple regular Muscle, described according to its natural appearance, in the Belly of which the fleshy Fibres being opened, are diduced one from another, that the membranaceous Fibrils may be the better beheld.
- A. The right Tendon.
- B. The left opposite Tendon.
- C. The fleshy Belly; all the fleshy Fibres of which lye one by another equal and parallel, but in even and oblique Angles between either Tendon.
- D. The aperture of the fleshy Fibres, which being drawn aside, the membranaceous Fi∣brils, thickly crossing them, appear.
The Second Figure
Shews a simple Muscle cleft in the middle, after the Tendon being cut off, and portions of it pulled away, that the interiour series of the fleshy Fibres, or their commixtures or mingling with the Tendons, may appear.
- A A. The right Tendon being placed above, both portions of which divided, do in some measure appear.
- B B. The left opposite Tendon placed below, either portions of which divided, lye hid for the most part under the Flesh, those towards the edges being only conspicuous.
- C D. Portions of the fleshy Belly divided and separated, which before (this being laid upon that) did cohere, in either of which all the fleshy Fibres proceed equally, and in like manner obliquely from one Tendon to another.
- E. Some membranaceous Fibrils represented, thickly crossing the fleshy Fibres.
The Third Figure
Exhibits a certain Muscle less compounded, to whose two fleshy Bellies two compounded Tendons also (equal to four simple ones) are destinated.
- A. The exteriour compounded Tendon, embracing either side of the fleshy Fibres, which being almost only conspicuous on the edges, lyes hid for the most part under the Flesh.
- B. The interiour compounded Tendon, entring into the middle of the Flesh, which receives on both sides the fleshy Fibres, sent from either side of the exteriour Tendon.
- C. The first Belly of the fleshy Fibres, all whose equal and parallel Fibres lye between the opposite sides of the Tendons in oblique Angles and equal.
- D. The second Belly of the fleshy Fibres, all whose Fibres being in like manner formed, are beheld in the same as in the other Belly.
- E E. Both extremities of the exteriour compounded Tendon.
- F. The extremity or end of the interiour compounded Tendon, the like to the other being opposite, at an equal distance from the end of the Muscle.
The Fourth Figure
Shews a regular compounded Muscle, divided and opened in the middle, so that the inte∣riour face of either Belly may appear.
- A. The exteriour compounded Tendon cleft into four parts.
- B B. Portions of one side of the divided Tendon separated from the other.
- C. Portions near sited, of the other side of the divided Tendon, which for the greatest part lye hid under the flesh.
- D D. The flesh of one Belly also divided, and separated one far from another.
- E E. The flesh of the other Belly also divided, and placed near one another.
- F. The interiour compounded Tendon entring the middle of the Flesh.
- G G. Portions of the same Tendon divided, and with portions of the Bellies, which they receive, separated apart.
