Septum Glandis
The septum glandis, also septum of the glans, refers to the fibrous partition of the ventral aspect of the glans penis that separates the two glans wings in the ventral midline. The septum extends from the urethral meatus through the glanular urethra ( fossa navicularis) and ends in the tunica albuginea of the human penis. Externally it is attached to the frenulum which extends lower on the neck of the penis. The septum glandis results during the embryonic development of the male fetus as the two sides of the genital tubercle merge in the midline without fusing, to form a hollow tube that encloses the male urethra. The two sides of the preputial lamina that will become the prepuce approach on the underside and remain separated by a thin tissue of mesenchyme that will form the frenulum. Ventrally, the two wings of the corona do not fully attach to each other, remaining separated at the subglanular level. See also * Septum of the penis *Scrotal septum The septum of the scro ...

Genital Tubercle
A genital tubercle or phallic tubercle is a body of tissue present in the development of the reproductive system. It forms in the ventral, caudal region of mammalian embryos of both sexes, and eventually develops into a primordial phallus. In the human fetus, the genital tubercle develops around week 4 of gestation, and by week 9 becomes recognizably either a clitoris or penis. This should not be confused with the sinus tubercle which is a proliferation of endoderm induced by paramesonephric ducts. Even after the phallus is developed, the term genital tubercle remains, but only as the terminal end of it, which develops into either the glans penis or the glans clitoridis. The genital tubercle is sensitive to dihydrotestosterone and rich in 5-alpha-reductase, so that the amount of fetal testosterone Testosterone is the primary sex hormone and anabolic steroid in males. In humans, testosterone plays a key role in the development of male reproductive tissues such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scrotal Septum
The septum of the scrotum is a vertical layer of fibrous tissue that divides the two compartments of the scrotum. It consists of flexible connective tissue. Its structure extends to the skin surface of the scrotum as the scrotal raphe. It is an incomplete wall of connective tissue and nonstriated muscle (dartos fascia) dividing the scrotum into two sacs, each containing a testis. Histological septa are seen throughout most tissues of the body, particularly where they are needed to stiffen soft cellular tissue, and they also provide planes of ingress for small blood vessels. Because the dense collagen fibres of a septum usually extend out into the softer adjacent tissues. A septum is a cross-wall. Thus it divides a structure into smaller parts. The scrotal septum is used in reconstructive surgery to restore tissue and or reproductive organs injured or severed by trauma.Male Sexual Dysfunction: Pathophysiology and Treatment, edited by Fouad R.

Septum Of The Penis
The two corpora cavernosa penis are surrounded by a strong fibrous envelope consisting of superficial and deep fibers. The superficial fibers are longitudinal in direction, and form a single tube which encloses both corpora; the deep fibers are arranged circularly around each corpus, and form by their junction in the median plane the septum of the penis. This septum is composed of multiple strands of connective tissue, similar to that of the tunica albuginea. It is thick and complete behind, where the corpora cavernosa become independent and form separate crura, but it's imperfect in the front, where it consists of a series of vertical bands arranged like the teeth of a comb; it is therefore named the ''septum pectiniforme'' ( pectinate septum).

Corona Of Glans Penis
The corona of glans penis or penis crown refers to the rounded projecting border that forms at the base of the glans in human males. The corona overhangs a mucosal surface, known as the neck of the penis, which separates the shaft and the glans. The deep retro-glandular coronal sulcus forms between the corona and the neck of the penis. The corona and the neck are highly vascularized areas of the penis. The axial and dorsal penile arteries merge together at the neck before entering the glans. Small venous tributaries deriving from the corona drain the glans forming a venous retro-coronal plexus before merging with the dorsal veins. The circumference and the underside of the corona are densely innervated by several types of nerve terminals and are considered by males an erogenous area of the glans. In some males, small skin-colored bumps, known as pearly penile papules Pearly penile papules (PPP) are benign small bumps on the human penis. They vary in size from 1–4&nb ...

Mesenchyme
Mesenchyme () is a type of loosely organized animal embryonic connective tissue of undifferentiated cells that give rise to most tissues, such as skin, blood or bone. The interactions between mesenchyme and epithelium help to form nearly every organ in the developing embryo. Vertebrates Structure Mesenchyme is characterized morphologically by a prominent ground substance matrix containing a loose aggregate of reticular fibers and unspecialized mesenchymal stem cells. Mesenchymal cells can migrate easily (in contrast to epithelial cells, which lack mobility), are organized into closely adherent sheets, and are polarized in an apical-basal orientation. Development The mesenchyme originates from the mesoderm. From the mesoderm, the mesenchyme appears as an embryologically primitive "soup". This "soup" exists as a combination of the mesenchymal cells plus serous fluid plus the many different tissue proteins. Serous fluid is typically stocked with the many serous elements, su ...

Foreskin
In male human anatomy, the foreskin, also known as the prepuce, is the double-layered fold of skin, mucosal and muscular tissue at the distal end of the human penis that covers the glans and the urinary meatus. The foreskin is attached to the glans by an elastic band of tissue, known as the frenulum. The outer skin of the foreskin meets with the inner preputial mucosa at the area of the mucocutaneous junction. The foreskin is mobile, fairly stretchable and sustains the glans in a moist environment. Except for humans, a similar structure, known as penile sheath, appears in the male sexual organs of all primates and the vast majority of mammals. In humans, foreskin length varies widely and coverage of the glans in a flaccid and erect state can also vary. The foreskin is fused to the glans at birth and is generally not retractable in infancy and early childhood. Inability to retract the foreskin in childhood should not be considered a problem unless there are other symp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Male Urethra
The urethra (from Greek οὐρήθρα – ''ourḗthrā'') is a tube that connects the urinary bladder to the urinary meatus for the removal of urine from the body of both females and males. In human females and other primates, the urethra connects to the urinary meatus above the vagina, whereas in marsupials, the female's urethra empties into the urogenital sinus. Females use their urethra only for urinating, but males use their urethra for both urination and ejaculation. The external urethral sphincter is a striated muscle that allows voluntary control over urination. The internal sphincter, formed by the involuntary smooth muscles lining the bladder neck and urethra, receives its nerve supply by the sympathetic division of the autonomic nervous system. The internal sphincter is present both in males and females. Structure The urethra is a fibrous and muscular tube which connects the urinary bladder to the external urethral meatus. Its length differs between the sexes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Male Reproductive System
The male reproductive system consists of a number of sex organs that play a role in the process of human reproduction. These organs are located on the outside of the body and within the pelvis. The main male sex organs are the penis and the testicles which produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized ovum (zygote) develops into a fetus, which is later born as an infant. The corresponding system in females is the female reproductive system. External genital organs Penis The penis is the male intromittent organ. It has a long shaft and an enlarged bulbous-shaped tip called the glans penis, which supports and is protected by the foreskin. When the male becomes sexually aroused, the penis becomes erect and ready for sexual activity. Erection occurs because sinuses within the erectile tissue of the penis become filled with blood. The arteries of the penis are dilated while the veins are compressed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiber
Fiber or fibre (from la, fibra, links=no) is a natural or artificial substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene. Synthetic fibers can often be produced very cheaply and in large amounts compared to natural fibers, but for clothing natural fibers can give some benefits, such as comfort, over their synthetic counterparts. Natural fibers Natural fibers develop or occur in the fiber shape, and include those produced by plants, animals, and geological processes. They can be classified according to their origin: * Vegetable fibers are generally based on arrangements of cellulose, often with lignin: examples include cotton, hemp, jute, flax, abaca, piña, ramie, sisal, bagasse, and banana. Plant fibers are employed in the manufacture of paper and textile (cloth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frenulum Of Prepuce Of Penis
The frenulum of prepuce of penis, often known simply as the frenulum, is a highly erogenous elastic band of tissue under the glans penis that connects the foreskin to the vernal mucosa, and helps contract the foreskin over the glans. Along with the ridged bands at the tip of the foreskin, it is considered to be the most sensitive part of the penis to fine-touch. In the event of frenulum breve or frenular chordee, or to ensure that the glans can be freely and completely exposed, the frenulum may be partially or totally removed in a procedure known as frenulectomy. Sensitivity The frenulum and the associated tissue delta on the underside of the penis below the corona has been described in sexuality textbooks as "very reactive" and "particularly responsive to touch that is light and soft". The "underside of the shaft of the penis, meaning the part below the corona" is a "source of distinct pleasure". Crooks and Baur observe that two extremely sensitive specific locations that ma ...

Human Penis
The human penis is an external male intromittent organ that additionally serves as the urinary duct. The main parts are the root (radix); the body (corpus); and the epithelium of the penis including the shaft skin and the foreskin (prepuce) covering the glans penis. The body of the penis is made up of three columns of tissue: two corpora cavernosa on the dorsal side and corpus spongiosum between them on the ventral side. The human male urethra passes through the prostate gland, where it is joined by the ejaculatory duct, and then through the penis. The urethra traverses the corpus spongiosum, and its opening, the meatus (), lies on the tip of the glans penis. It is a passage both for urination and ejaculation of semen (''see'' male reproductive system.) Most of the penis develops from the same embryonic tissue as the clitoris in females. The skin around the penis and the urethra share the same embryonic origin as the labia minora in females. An erection is the st ...
