THE FORTY-EIGHTH TABLE.
Fig. 1.
THE Upper and Fore-parts of the Penis and Bladder of Urine, well Exprest after a Curious Dissection.
A A, The Cavernous Bodies of the Penis Whole.
B B, That Part of the Skin which Composes the Praeputium.
b, The Reduplication or Inner Membrane of the Praeputium.
C D, The Blood-Vessels which Adorn the Up∣per-part or Dorsum Penis.
E, The Glans or Balanus.
About the Neck of the Glans where the Pre∣puce is join'd to the Penis, are plac'd the Glan∣dulae Odoriferae, taken Notice of by the Accu∣rate Anatomist Dr. Tyson. These separate a Mat∣ter, which serves to Lubricate the Prepuce, and make it slide easily on the Glans. These Glan∣dules of the Prepuce are frequently very much Tumified in Venereal Contacts, and especially if these Parts happen to be Ulcerated, whence a Foetide Matter proceeds.
F F, The Urine Bladder Open'd.
G G, Parts of the Ureters next the Bladder.
H H, Portions of the Vasa Deferentia.
I I, Parts of the Vesiculae Seminales in View.
K, The Caruncula or Caput Gallinaginis, and Ostiolae Prostatarum as they Appear after the Fore-part of the Urethra is Divided.
K L, The Prostatae whose Upper-part is Di∣vided with the Urethra.
M, The Vein of the Penis which is Comprest in an Erection, by a Ligament plac'd under the Ossa pubis.
N N, The Two Arteries of the Penis.
O O, The Nerves.
P P, The Corpora Cavernosa free'd from the Ossa Pubis and their Musculi Erectores.
Q Q, Parts of the Musculus Accelerator Uri∣nae free'd from the Bulb of the Cavernous Body of the Urethra, and Expanded.
Fig. 2.
A A, Parts of the Glans Penis view'd with a Microscope.
B B, The Common Membrane of the Penis or Praeputium.
C C, The Proper Membrane of the Glans se∣parated.
D E F G, Divers Rows of Fibres dispos'd like Membranes, and Intricately interwoven with the Internal Membranes and Blood-Vessels.
Fig. 3.
The Fore-part of a Portion of the Penis, to∣gether with the Glans Dri'd after Inflation.
A A A, The Inner-parts of the Corpora Ca∣vernosa Penis.
B, The Septum of the Corpora Cavernosa.
C D, The Cells of the Cavernous Bodies which Open into the Sides of the Veins, and are Sustain'd by the Fibres which pass to and fro' from the Cap∣sula or Exterior Membrane of the Corpora Ca∣vernosa and Septum. These Fibres are not so Conspicuous in the Humane Penis, as in that of a Horse: Nor are the Cells of a Humane Penis so Evident as they are in Quadrupedes: This Stru∣cture of the Cavernous Bodies of the Penis seem∣ing to agree with the Spleen in the same Animal.
E E, The Arteries passing thro' the Middle of each Cavernous Body of the Penis.
After taking off the Tops of the Corpora Caver∣nosa Penis, from a Patient who had the Glans very much Ulcerated, I could easily take hold of the Ends of the Bleeding Arteries with my Forceps, and pass a Ligature on their Trunks, and Tie them; which Practice in such Cases is Preferable to the Application of Stypticks which cause Pain.
F, The Glans.
G, The Orifice of the Meatus Urinarius in the Glans.
Fig. 4.
The Hinder-part of the Penis in like Manner prepar'd by Inflation, &c.
A A, A Portion of the Capsula of the Caver∣nous Body of the Penis cut, and rais'd up; on which Part of the Rete of the Corpus Cavernosum do's Appear.
B, The Corpus Cavernosum.
C, The Urethra Open'd.
D, The Corpus Cavernosum Urethrae Divided.
E, The remaining Part of the Urethra and its Cavernous Body entire.
F, The Glans Penis.
Fig. 5, 6.
The Corpora Cavernosa Penis and that of the Urethra, after a Transverse Section when Inflated and Dri'd.
A A, The Capsula or Strong Membrane of the Cavernous Bodies of the Penis.
B B, The Corpora Cavernosa Penis; in the Middle of each of which the Trunks of Two Ar∣teries pass according to their Length.
C, The Septum.
D, The Strong Membrane or Capsula of the Corpus Cavernosum Urethrae.
E, The Circular Cavernous Body of the Ure∣thra.
A particular Account of the Structure of this Part is Inserted in an Appendix to our Myotomia Reformata; where the Lympheducts of the Hu∣mane Penis are Describ'd, and some Phaenomena relating to them Explain'd: Since the Writing of which, I have had an Opportunity of seeing the Lympheducts on the Penis of a Dog, where I Ob∣serv'd by Blowing into the Veins, the Lymphe∣ducts were immediately Distended.
