Study Notes
Anterior Abdominal Wall
- The primary fascia of the anterior abdominal wall is called Camper's fascia.
- The rectus sheath is formed by the fusion of fibrous aponeuroses of the three abdominal wall muscles.
Abdominal Wall Muscles
- The inferior epigastric vessels anastomose with the superior epigastric artery and vein.
Nerves
- The ilioinguinal nerve supplies the skin of the mons pubis, upper labia majora, and medial upper thigh.
- The iliohypogastric nerve is an anterior ramus of the thoracic spinal nerves.
- The pudendal nerve lies within the Alcock canal.
Perineal Body
- The perineal body is located in the anterior triangle.
Anal Sphincter
- The internal anal sphincter is composed of smooth muscle, not striated muscle.
Ligaments
- The round ligament terminates in the labia majora.
Anesthesia
- Regional analgesia for cesarean delivery or for puerperal sterilization ideally extends to T4.
Vulva
- The vulva refers to the external female genitalia.
- The labia majora is covered with hair and contains apocrine, eccrine, and sebaceous glands.
- The clitoris is located beneath the prepuce and projects downward and inward toward the vaginal opening.
Vagina
- The vagina is composed of three histological layers: stratified squamous epithelium, elastic lamina propria, and fibromuscular layer.
- Vaginal secretions are notably increased during pregnancy.
- The vascular supply to the vagina is via the uterine and vaginal arteries.
Clitoris
- The blood supply to the clitoral body is primarily from the deep artery of the clitoris.
Perineum
- The perineum is divided into an anterior triangle and a posterior triangle by an arbitrary line joining the ischial tuberosities.
- The vulva receives sensory and parasympathetic nervous supply from the ilioinguinal nerve and the pudendal nerve.
Glands
- The Bartholin glands are located superior to the vestibular bulb and deep to the bulbospongiosus muscle.
Hymen
- The hymen is torn not only during first coitus but also by other penetration.
Ovaries
- The right ovarian vein empties into the inferior vena cava, not the left renal vein.
- The sympathetic nerves of the ovaries originate in the ovarian plexus.
- The sensory afferents of the ovaries enter the spinal cord at the T10 level.
Cervix
- The cervix undergoes changes during pregnancy.
Fallopian Tubes
- The fallopian tubes are derived from the Mullerian duct.
Uterus
- The lining of the uterus is stratified columnar epithelium, not stratified squamous epithelium.
Test your knowledge on the anatomy of the anterior triangle, focusing on the urethra and its measurements, lining, blood supply, and innervation. This quiz is based on information from McGraw-Hill Education's "Anatomy of the Anterior Triangle" textbook.
