Exam Preparation Tips

• Review Homework and Quizzes: Problems in these assessments often appear verbatim on the exam. Revisit the specific percentage questions (e.g., 40%, 50%, etc.) which were commonly included in past exams.

• Revisit Study Material: Utilize study guides shared in class. Reviewing slides and images is crucial for visualizing anatomical locations and organ functions.

Surface Anatomy of the Abdomen

• Nine Regions of the Abdomen: Understand the anatomical divisions and which organs are located in these regions. Particularly:

  • Left Upper Quadrant: Spleen

  • Umbilical Region: Small intestine, kidneys

  • Pay attention to the location of major organs for potential exam questions.

Muscles of the Abdomen

• Muscle Groups:

  • Lateral Group: External abdominal oblique, internal abdominal oblique

  • Medial Group: Rectus abdominis, pyramidalis

  • Innervation: All innervated by the lower six intercostal nerves and L1.

• Cremaster Muscle: Innervated by the genital branch of the genitofemoral nerve.

Inguinal Ligament

• Origin: Anterior superior iliac spine of the ilium.

• Clinical Relevance: Questions may reference the innervation and function, including questions related to the cremaster reflex.

Rectus Sheath

• Contents Include:

  • Rectus abdominis muscle

  • Inferior and superior epigastric vessels

  • Lower intercostal nerves including the subcostal nerve.

Inguinal Canal

• Boundaries:

  • Deep Inguinal Ring: Gap in fascia transversalis

  • Superficial Inguinal Ring: Gap in the aponeurosis of the external abdominal oblique muscle.

• Contents:

  • Male: Spermatic cord,

  • Female: Round ligament of uterus, lymphatics.

  • Recognize differences in contents for exam questions.

Clinical Significance of the Inguinal Canal

• Cryptorchidism and Hydrocele Conditions: Understand definitions and clinical presentations.

  • Cryptorchidism: Testes fail to descend.

  • Hydrocele: Fluid accumulation around the spermatic cord.

  • These may present in clinical scenarios in exam questions.

Peritoneal Spaces

• Different compartments like subphrenic space, right subhepatic pouch (pouch of Morrison) where fluid accumulation can occur post-surgery.

• Recognize Potential Locations for fluid buildup relevant in postoperative care.

Foregut, Midgut, Hindgut

• Foregut Organs: Esophagus, stomach, liver, pancreas (blood supply via celiac trunk).

• Midgut: Duodenum, jejunum, ileum (blood supply via superior mesenteric artery).

• Hindgut: Remaining colon (blood supply via inferior mesenteric artery).

Examining the Small Intestine

• Divisions: Duodenum (has retro and intraperitoneal aspects), jejunum, ileum.

• Key Functions: Digestion and absorption of nutrients via mucosal cells.

• Blood Supply: Arteries from superior mesenteric; no significant veins in terms of unique drainage points necessary for the exam.

Large Intestine and Appendix

• Cecum and Appendix: Location and clinical significance of McBurney’s point for appendicitis diagnosis.

• Venous Drainage: Via superior mesenteric vein back to the portal vein.

Pathologies of the Gastrointestinal Tract

• Hypertrophic Pyloric Stenosis: Projective vomiting without bile among infants; a common exam scenario.

• Gallstones and their Treatment: 5 F's indicating risk groups (Female, Fertile, Forty, Fair, Full-figured).

The Urinary System

• Kidney Functions: Regulation of blood pressure (renin-angiotensin-aldosterone system) and urine production.

• Adrenal Gland: Functions related to hormones affecting metabolism and bodily functions.

Male and Female Reproductive Systems

• Differences in Pelvis Anatomy: Wider female pelvis adapts for childbirth, important in answering anatomical questions.

• Menstrual Cycle Phases: Understand phases relating to hormone fluctuation and physiological changes in the body.

• Ectopic Pregnancy: Key clinical relevance including recognition of severe abdominal pain, critical for diagnosis during exams.
