Development of digestive organs
Optional reading The Developing Human: Clinically Oriented Embryology, 12th ed., chapter 11. Introduction As always, understanding the development of the body’s organ systems and parts illuminates their gross anatomy. The definitive anatomy of digestive organs in the abdomen is a perfect example. The embryo starts out with a simple straight tube in the 4th week, […]
Head and neck development
Optional reading Langman’s Medical Embryology: Chapter 17, Head and Neck. The relevant sections are: Introduction, Pharyngeal Apparatus, Thyroid Gland, and Face. Most of the events that produce the definitive anatomy of the head and neck are covered in this chapter. The pharyngeal apparatus (the source of the primordial tissues) is discussed first, followed by detailed […]
Overview of the neck viscera; thyroid and parathyroid glands
Optional reading Moore, Clinically Oriented Anatomy, 7th ed., Viscera of neck section through Nerves of parathyroid glands. In thinking about the overall architecture of the neck, it can be organized into 4 units: 1. Visceral unit The visceral unit contains the neck’s visceral organs (the focus of this chapter). It is located anteriorly. 2. Vertebral […]
Infracolic organs: The intestines
Optional reading Clinically Oriented Anatomy, 8th ed., chapter 5, Abdominal viscera. Recall from The peritoneal cavity and mesenteries that the peritoneal cavity is divided into supracolic and infracolic regions, using the transverse colon and its mesentery (transverse mesocolon) as the borderline. In Organs in the supracolic region, the supracolic organs were described. In this chapter, […]

Perineum
Optional Reading Clinically Oriented Anatomy, 9th ed., Perineum section. The perineum is the inferior-most region of the trunk, located between the thighs and buttocks. In the anatomic position the perineum is partially hidden because the thighs are together. When the thighs are abducted, the perineum has a diamond shape. Due to the forward tilt of […]
