Layers of the scrotum consist of skin, dartos muscle, external spermatic fascia, cremasteric fascia and internal spermatic fascia, which is in close contact with the parietal layer of the tunica vaginalis. (medscape.com)
The skin and dartos layers of the scrotum are supplied by the perineal branch of the internal pudendal artery in addition to the external pudendal branches of the femoral artery. (medscape.com)
Lymphatic drainage of the skin of the scrotum is by the external pudendal vessels to the medial superficial inguinal lymph nodes. (medscape.com)
Each testis is 4-5-cm long, 2-3-cm wide, weighs 10-14 g and is suspended in the scrotum by the dartos muscle and spermatic cord. (medscape.com)
In the scrotum, it is intermingled with involuntary muscular fibres, and constitutes the dartos muscle, which assists in suspending the testes and corrugating the skin of the scrotum. (co.ma)
This fascia also forms the septum of the scrotum, which, extending upwards, incompletely separates the two testes and their coverings. (co.ma)
The deeper membranous layer is attached laterally to the pubic arch, posteriorly to the base of the fascia inferior of the urogenital diaphragm and in the median plane to the root of the penis (bulb and corpus cavernosum urethra) by a median raphe continuous, farther forwards, with the septum of the scrotum mentioned above. (co.ma)
The tunica dartos (smooth m.), found just below the skin of the scrotum , can have a sustained contraction and helps hold the testis close to the body for warmth, since a specific temperature is needed for spermatogenesis. (umn.edu)
It extends through the scrotum and around the testis, being situated deep to the external spermatic fascia. (verenigdlinks.eu)
Perineal3
The subcutaneous tissue of perineum (or superficial perineal fascia) is a layer of subcutaneous tissue surrounding the region of the perineal body. (wikipedia.org)
The DNP arises close to the perineal nerve as the pudendal nerve exits Alcock's canal, a tunnel formed by a division of the obturator fascia along the lateral wall of the ischiorectal fossa. (cirp.org)
The perineal muscles are naturally separated into a superficial and a deep set by the fascia inferior of the urogenital diaphragm. (co.ma)
Colles1
The deep layer of superficial fascia (fascia of Colles) is thin, aponeurotic in structure, and of considerable strength, serving to bind down the muscles of the root of the penis. (wikipedia.org)
Because Fournier gangrene is predominately an infectious process of the superficial and deep fascial planes, understanding the anatomic relationship of the skin and subcutaneous structures of the perineum and abdominal wall is important. (medscape.com)
The superficial fascia of the perineum possesses certain special features. (co.ma)
The fascia over the posterior part of the perineum fills up the ischio-rectal fossæ, in the form of two pads of adipose tissue, on either side of the rectum and anal canal. (co.ma)
The fascia in the anterior part of the perineum closely resembles the same fascia in the groin. (co.ma)
The importance of this fascia lies in relation to the extravasation of urine from a rupture of the urethra in the perineum. (co.ma)
The deep fascia of the perineum exists only in the form of the delicate fascia of the muscles. (co.ma)
Spermatic cord1
Apr 12, 2023 · The cremasteric muscle fibers unite with the surrounding loose connective tissue to comprise a thin covering for the spermatic cord known as the cremasteric fascia. (verenigdlinks.eu)
The layers deep to the dartos muscle are supplied by the cremasteric branch of the inferior epigastric artery. (medscape.com)
Buck's3
Dorsal nerves supply penile skin sensation and lie within Buck's fascia. (loriamedical.com)
Buck's fascia circumferentially envelops all three structures, splitting into two leaves ventrally at the spongiosum. (loriamedical.com)
Dorsal nerves arising from the pudendal nerves travel within Buck's fascia, together with the dorsal arteries and veins, to supply sensation to penile skin[8], Fig. 2. (loriamedical.com)
Scarpa's1
Scarpa's fascia and clinical signs: the role of the membranous superficial fascia in the eponymous clinical signs of retroperitoneal catastrophe. (radiopaedia.org)
Inguinal canal1
This diagram also indicates the oblique inguinal canal with deep and superficial rings. (anatomylearner.com)
Labia1
In the female the superficial fascia, in which there is a considerable quantity of fat, takes a large share in the formation of the mons Veneris and labia majora pudendi. (co.ma)
Fascial1
This infectious process involves the superficial and deep fascial planes of the genitalia. (medscape.com)
The skin cephalad to the inguinal ligament is backed by Camper fascia, which is a layer of fat-containing tissue of varying thickness and the superficial vessels to the skin that run through it. (medscape.com)
The fascia allows the subcutaneous fat ( Camper fascia ) to slide freely over the underlying thoracic wall, rectus sheath , and external oblique aponeurosis. (radiopaedia.org)
The cremaster m . is in a layer of fascia just outside of the parietal vaginal tunic (cross sectional image below, C) and helps in pulling up the testis (and contracts sporadically). (umn.edu)
Membranous layer1
Scarpa fascia is a membranous layer of superficial fascia that extends over the lower thoracic and anterior abdominal wall , anterior to the midaxillary lines . (radiopaedia.org)
Fibrous1
Over the tuberosities of the ischium the fat is intermingled with bands of fibrous tissue closely adherent to the subjacent deep fascia. (co.ma)
Skin2
In the middle line, it is adherent to the skin on the raphe and to the deep layer of the superficial fascia. (wikipedia.org)
Antegrade dissections of the DNP were performed after removal of the penile shaft skin and fasciae. (cirp.org)
Muscle1
The superficial surface of the external muscle is covered by the muscles of the chest, axilla, abdomen, and back. (co.ma)
Abdominal1
Anteriorly the fascia is continued over the spermatic funiculi to the anterior abdominal wall. (co.ma)
Layer1
The superficial layer is thick, loose, areolar in texture, and contains in its meshes much adipose tissue, the amount of which varies in different subjects. (wikipedia.org)
Extends1
It extends from the deep inguinal ring to the superficial inguinal ring . (umn.edu)
Consists1
The superficial fascia of this region consists of two layers, superficial and deep. (wikipedia.org)
Wall1
Superiorly and laterally, Scarpa fascia fades out over the upper thoracic wall and midaxillary lines. (radiopaedia.org)
