  1. Biology 224 Human Anatomy and Physiology - II Lecture 01 Dr. Stuart S. Sumida Organizational Overview of Thorax, Abdomen, Pelvis

  2. Thorax Abdomen Pelvis/Perineum

  3. Abdomen and Thorax separated by DIAPHRAGM. Thorax and Pelvic region not separated by a defined partition.

  4. Thorax Abdomen

  5. DIAPHRAGM: • Derived from cervical hypaxial musculature (why scalene muscles are all that is left of lateral hypaxial musculature of neck) • Innervated by Right and Left PhrenicNeve (C3,4,5)

  6. Review of Early Development of Humans Basic Cross-section of the Human

  7. COELOM AND ITS CONTENTS: • Filled with coelomic fluid. • PARIETAL PERITONEUM – mesodermally derived layer coating interal surface of body wall. • VISCERAL PERITONEUM – mesodermally derived layer coating internal organs. • MESENTARY – bi-layer of mesodermally derived material that connects to dorsal or ventral midline to suspend gut internally. • PARIETAL PLEURA – serial homolog of parietal peritoneum in thorax. • VISCERAL PLEURA– serial homolog of visceral peritoneum in thorax.

  8. NECK and THORAX and MAJOR COMPONENTS OF RESPIRATORY SYSTEM • Lungs • Bronchi • Trachea • Pharynx • Nasal Pharynx • Oral Pharynx • Common Pharynx

  9. COMPONENTS OF EMBRYONIC FOREGUT • Including and up to: • Stomach • Duodenum (first bend of small intestine) • Liver • Gall bladder • Pancreas • Sympathetic Innervation: Greater splanchnic nerve (T5-T9) • Parasympathetic Innervation: Vagus Nerve (X) • Arterial Supply: Celiac Artery and its branches • Venous Drainage: Splenic Vein and its tributaries. Review of Early Development of Humans Basic Cross-section of the Human

  10. Hepatic Portal Vein Bile Duct

  11. Liver Stomach

  12. COMPONENTS OF EMBRYONIC MIDGUT • Including and up to: • Jejunum and Ileum of small intestine • Appendix • Ascending Colon • Transverse Colon (up to LEFT COLIC FLEXURE) • Sympathetic Innervation: Lesser Splanchnic nerve (T10-T11) • Parasympathetic Innervation: Vagus Nerve (X) • Arterial Supply: Superior Mesenteric Artery and its branches • Venous Drainage: Superior Mesenteric Vein and its tributaries.

  13. COMPONENTS OF EMBRYONIC HINDGUT • Including and through to: • Descending Colon • Sigmoid Colon • (through to) Rectum • Sympathetic Innervation: Least Splanchnic nerve (T12) • Parasympathetic Innervation: Sacral Outflow (S2-4) • Arterial Supply: Inferior Mesenteric Artery and its branches • Venous Drainage: Inferior Mesenteric Vein and its tributaries.

  14. HEPATIC PORTAL SYSTEM: Hepatic portal vein Splenic vein (foregut) Superior Mesenteric Vein (midgut) Inferior Mesenteric Vein (hindgut)

  15. INTRAPERITONEAL vs. RETROPERITONEAL Most of the internal organs are surrounded by visceral peritioneum – the INTRAPERITONEAL condition. Some organs (e.g. kidneys) are between peritoneum on one surface, and the body wall on the other – the RETROPERITONEAL condition.

  16. Retroperitoneal components of abdominal cavity

  17. STRUCTURES WITHIN THE PELVIS • End of digestive system • Female reproductive organs • Bladder • Ducts to, and exiting from, bladder
