The navicular fossa is a short dilated portion of (the spongy (or cavernous or penile) portion of) the male urethra within the glans penis just proximal to the external urethral meatus. The roof of the fossa is especially dilated, forming a lacuna; medical instruments being inserted into the male urethra should initially be directed towards the ...
In male anatomy, the lacuna magna (also called Guérin's sinus) is the largest of several recesses in the roof of the navicular fossa of the male urethra. Structure [ edit ]
[54] [55] In cats, the glans penis is covered with spines. Penile spines also occur on the glans of male and female spotted hyenas. [54] In male dogs the glans penis is smooth and consists of two parts called the bulbus glandis and pars longa glandis. [56] The glans of a fossa's penis extends about halfway down the shaft and is spiny except
It is narrow, and of uniform size in the body of the penis, measuring about 6 mm in diameter; it is dilated behind, within the bulb, and again anteriorly within the glans penis, where it forms the fossa navicularis urethrae. The spongy urethra runs along the length of the penis
The urinary meatus [a] (/ m iː ˈ eɪ t ə s /, mee-AY-təs; pl.: meati or meatuses), also known as the external urethral orifice, is the opening of the penis or vulva where urine exits the urethra during urination. It is also where semen exits during male ejaculation, and other fluids during female ejaculation. The meatus has varying degrees ...
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. [1] The septum extends from the urethral meatus through the glanular urethra (fossa navicularis) and ends in the tunica albuginea of the human penis.
Fossa navicularis is an alternate name for two different boat-shaped depressions: fossa of vestibule of vagina; navicular fossa of male urethra
The largest of these recesses is called lacuna magna (or the sinus of Guérin, or Guérin's sinus), which is situated on the upper surface of the fossa navicularis. Located deeper within the lacunae are branching mucous tubules called the glands of Littre.
