Description and Demonstration of the Superficial and Deep Perineal Pouches

Introduction

The perineal region is a complex anatomical area divided into superficial and deep pouches, each housing essential structures related to urogenital and muscular functions.

Superficial Perineal Pouch

Boundaries

The superficial perineal pouch is enclosed by the perineal membrane superiorly and Colles' fascia inferiorly.

Contents

• Bulbospongiosus muscle
• Ischiocavernosus muscle
• Superficial transverse perineal muscle
• Proximal part of the spongy urethra (in males)
• Greater vestibular glands (in females)

Deep Perineal Pouch

Boundaries

The deep perineal pouch lies between the perineal membrane and the pelvic diaphragm.

Contents

• Deep transverse perineal muscle
• External urethral sphincter
• Bulbo-urethral glands (in males)
• Portions of the urethra
• Neurovascular structures supplying the perineum

Clinical Significance

Damage to structures within the deep perineal pouch can lead to urinary incontinence, sexual dysfunction, or compromised pelvic stability.
