- For the clam genus of family Carditidae, see Glans (bivalve).
The glans (Template:IPAc-en, plural "glandes" Template:IPAc-en; from the Latin word for "acorn") is a vascular structure located at the tip of the penis in male mammals or a homologous genital structure of the clitoris in female mammals.
Structure
The exterior structure of the glans consists of mucous membrane, which is usually covered by foreskin or clitoral hood in naturally developed genitalia. This covering, called the prepuce, is normally retractable in adulthood.
The glans naturally joins with the inner labia, and the frenulum of the penis or clitoris. In non-technical or sexual discussions, often the word "clitoris" refers to the external glans alone, excluding the clitoral hood, frenulum, and internal body of the clitoris.
Gender differences
In males, the glans is known as the glans penis, while in females the glans is known as the clitoral glans.
In females, the clitoris is above the urethra. The glans of the clitoris is the most highly innervated part of the external female genitalia.
Development
In the development of the urinary and reproductive organs, the glans is derived from the genital tubercle.
