Cremasteres, or Suspensory Muscles.

The testicles are perpetually clothed with three tunics, namely: 1. The erythroides red; 2. The elytroides vaginal/sheath-like; 3. The albuginea white/nervous. The cremaster muscles grow onto the outermost membranes of the first tunic, one on each side, which muscles in males have their origin from the ligament of the pubic bone.

Dartos.

It is nothing other than the skin itself in which the testicles are suspended, as if contained in a purse, equipped with fleshy fibers by whose benefit this part is variously contracted and wrinkled.

Director of the Penis.

It arises from the appendage of the hip bone, beneath the origin of the nervous bodies, in the interior part of which the very thick exit of fibers also takes its start and vanishes due to its thinness.

Accelerator of Urine.

It arises fleshy from the sphincter ani sphincter of the anus, and when joined with its companion internally and from the side, it progresses to the anterior part of the penis and is inserted into the urethra urine duct, and it is commonly believed to have been made by nature for dilating the urethra.

Tab. 7.

Frontalis Frontal Muscle.

Lifting the forehead. Origin. Use.

This muscle arises from the highest part of the forehead where the hairline ends, and where the fleshy membrane adheres most firmly to the skull, not so far from the temporal muscle. Then, running straight down into the skin covering the eyes, it is inserted into the eyebrows. In dissecting and separating this muscle from the skull, you will find nerves sent into it from that very skull.

Corrugator Wrinkler.

Use.

Arising from the top of the nose or the greater corner of the eye, it proceeds obliquely toward the temples, where it thins out between the fibers of the frontal muscle and ends.

Occipitalis Occipital Muscle.

It is found in few; it takes its origin from the lambdoid suture seam in the skull and is inserted into the fleshy membrane which also receives the muscles of the forehead.

Orbicularis Clausor Closing Orbicular Muscle.

Depressing the eye.

It arises from a sharp beginning from the inner corner of the eye and the part of the eyebrow closest to the nose, whence it passes by an oblique and nearly transverse path, and having become fleshy and wide in passing, it is inserted into the outer corner.

Elevator of the Eyelid.

Elevator of the eye.

It arises thin, membranous, and pointed from the top of the nose near the corner of the lower eyelid, whence, carried by a transverse path almost to the middle of the eyelid, it becomes fleshy and is finally inserted, progressing transversely, into the same corner as the orbicular muscle.

Elevator of the wings of the nose.

Elevator of the nose. Use.

It arises from the top of the nose bone near the lachrymal tear orifice, with a sharp and simultaneously fleshy beginning. From there, descending from the side by a triangular route and running across that whole bone, it is inserted broad and fleshy into the wings of the nose, which it pulls upward and at the same time opens and dilates the nostrils.
