here these are the arteries arteries of the penis and finally further laterally we have got these two big nerves these are the nerves of the penis so basically on the dorsal aspect we have three sets of structures the deep dorsal vein of penis the artery of the penis and the derms of the penis one either side and either side the same thing we can see here also the deep dorsal vein of penis on either side we can see the artery of the penis and further laterally we can see the nerve of the penis now we shall reflect this aside and we will show some other structures we have cut open the dorsal aspect of the penis and we can see this structure here and the other content is here let's take a look at what we notice we notice a tough white sheet with a septum in between this is known as a tunica albujiña the tunica albujiña is a very tough structure and this is the one which is mainly responsible for maintaining for sustaining the erection this is the septum so therefore these two structures which are enclosed by the tunic albujiña these are known as corpora cavernosa this is the one which i mentioned earlier and if you notice when i squeeze we can see blood is coming out because these faces are filled with blood filled spaces and if you look very carefully in the middle there will be one major artery and one major artery that is known as a deep artery of the penis so how does this work blood flows through the deep artery of the penis which is the branch of the internal pudendal artery and then it gives multiple small branches here which are known as helicine arteries because they are highly coiled like helix under the influence of nitric oxide these helicine arteries they become uncoiled and they release blood into the cavernous spaces and that's what produces the erection according to simple law of mechanics and physics when there is increase in the blood flow this tunica albujiña it prevents much expansion on the lateral aspect instead it increases the length of the penis and that's how erection occurs and when it has it is time to undergo flexidity the blood is drained by means of venous channels through this deep torsal vein of penis which then rains into the prostrate venous plexus so this is how it works and it is mediated by special nerves which are known as cavernous nerves cavernous nerves are non-adrenergic non-colinergic nerves which release nitric oxide which is responsible for erection of the penis so this is about the corpora cavernosa now let's take a look at the corpus pongeosum the corpus pongeosum it starts as the bulb of the penis and it is attached to the outer surface of the perineal membrane in the superficial perineal pouch where my hand is located this bulb of the penis then continues and it becomes the corpus pongeosum it's composed of the same tissue and in the region of the bulb it is enclosed by a muscle called the bulbous pongeosus muscle this corpus pongeosum it is outside the teurica albogenia for obvious reasons because we don't want the corpus pongeosum to be compressed for the teurica albogenia however the corpus pongeosum and the corpus pongeosum they are both enclosed by this bux fascia and we can see the bux fascia is here and the bux fascia is on this side also this corpus pongeosum is the one which contains the urethra and that is what i showed you in the beginning instrument has gone through the urethra neatus and we can feel the urethra here and this same corpus pongeosum as it reaches the corona glandus it expands to form the glands of the penis this particular cadaver is circum sized so therefore we cannot see the previews and from the glands of the penis in the tip is the externally urethra neatus so this is about the structure of the penis to mention a few clinical correlations in certain parts of the word penile cancer is not very uncommon and then what we have to do what is known as either partial amputation of the penis or complete total amputation what i have shown you is basically something similar to partial amputation of the penis and if it's a total amputation then we have to remove the complete the crura of the penis the bulb of the penis and we have to do a perineal urethrostomy this crura of the penis is enclosed by yet another different muscle which is called ischocavanosis those also have to be removed if we want to do a total penile excision inflammation of the glands is called palonitis and usually it is accompanied by inflammation of the previews then it is known as palonopostitis there are many causes of that and all of you already know about circumcision which is excision of the previews if the prepucial orifice becomes very tight then it is known as phymosis and if it is partially loose and partially tight and when we retracted it gets stuck here that is known as paraphymosis these are some of the points which i wanted to mention to you about the penis its structure its coverings its blood supply and the mechanism of the main sexual erection thank you very much for watching dr sanjeev sanyal sanyal share in weeks is the camera person if you have any questions or comments please
