These are paired muscles located at the root of the penis which arise from the ischial arch and enclose the '''crura'''. They connect the penis to the ischial arch of the pelvis.

These paired muscles originate on the caudal vertebrae and insert on the ventrolateral surfaces of the penis. They follow the bulbospongiosus muscle to the epex of the penis.
These paired muscles originate on the caudal vertebrae and insert on the ventrolateral surfaces of the penis. They follow the bulbospongiosus muscle to the apex of the penis.
===Vasculature===
The artery of the penis is a direct branch off the internal pudendal artery. It splits into three branches:
*Artery of the bulb – supplies the corpus spongiosus
*Deep artery of the penis – supplies the corpus cavernosum
*Dorsal artery of the penis – supplies the glans penis
The prepuce covering the flaccid penis is supplied by anastamosis between the external pudendal artery and the artery of the penis.
===Innervation===
*Mostly parasympathetic from the paired pudendal nerves
*The glans penis and internal lamina of the prepuce are heavily infiltrated by sensory nerve endings responsible for stimulating ejaculation
===Lymphatics===
Lymph from the penis and prepuce drains into the superficial inguinal lymph nodes.
