Abdominal Exam IV: Acute Abdominal Pain Assessment
0 Views •
2023
Source: Joseph Donroe, MD, Internal Medicine and Pediatrics, Yale School of Medicine, New Haven, CT Abdominal pain is a frequent presenting concern in both the emergency department and the office setting. Acute abdominal pain is defined as pain lasting less than seven days, while an acute abdomen refers to the abrupt onset of severe abdominal pain with features suggesting a surgically intervenable process. The differential diagnosis of acute abdominal pain is broad; thus, clinicians must have a...

Abdominal Exam II: Percussion

Source: Alexander Goldfarb, MD, Assistant Professor of Medicine, Beth Israel Deaconess Medical Center, MA Medical percussion is based on the difference in pitch between the sounds elicited by tapping on the body wall. The auditory response to tapping depends on the ease with which the body wall vibrates, and is influenced by underlying organs, strength of the stroke, and the state of the body wall. There are three main medical percussion sounds: resonance (heard over lungs), tympany (heard over...

Source: Alexander Goldfarb, MD, Assistant Professor of Medicine, Beth Israel Deaconess Medical Center, MA Abdominal palpation, if performed correctly, allows for examination of the large and relatively superficial organs; for a skilled examiner, it allows for assessment of the smaller and deeper structures as well. The amount of information that can be obtained by palpation of the abdominal area also depends on the anatomical characteristics of the patient. For example, obesity might make...

Abdominal adhesions that form after surgery are a major cause of pain, infertility, and hospitalization and reoperation for small bowel obstruction. Our surgical procedure for creating abdominal adhesions in mice is a reliable tool to study the mechanisms underlying the formation of adhesions.

Stability comes from coordinated contraction rather than the action of one muscle alone. The external and internal obliques, transversus abdominis, and rectus abdominis contribute through complementary patterns that control trunk position and movement. This coordination allows the abdominal wall to provide support during posture changes, forceful movements, and activities that require controlled transfer of force.
The anterolateral muscles contribute to shared functions while emphasizing different mechanical roles. The obliques participate in coordinated trunk movement and stabilization, the transversus abdominis contributes to compression and support, and the rectus abdominis assists trunk control. Their interaction is more important than viewing any muscle in isolation because regional function depends on combined activity.
Contraction of the abdominal wall can compress the viscera and regulate intra-abdominal pressure. This pressure regulation links muscular activity with trunk stability, forceful movement, and breathing assistance. The abdominal wall therefore acts as part of a coordinated mechanical system, converting changes in muscle tension into support for the contents of the abdomen and the surrounding trunk.
Skin, connective tissue, muscle, and fascia are arranged in layers that combine different tissue properties. This organization gives the wall mechanical strength while retaining flexibility, allowing it to protect abdominal contents and accommodate movement. Studying the layers helps explain why regional anatomy must be considered alongside biomechanics when interpreting normal function or structural disruption.
Study typically connects the arrangement of tissues and muscles with their mechanical effects. Learners identify the anterolateral muscle groups, examine how their coordinated contractions affect posture, movement, visceral compression, and breathing, and then relate those functions to the layered organization. This approach builds a foundation for understanding both regional anatomy and abdominal biomechanics.
Knowledge of the wall’s layers, muscles, connective tissues, and fascia provides a framework for interpreting structural and functional changes. It helps place hernias and muscle injuries within the relevant anatomy and supports understanding of abdominal surgery or imaging. Developmental variation can also be considered in relation to the wall’s organized mechanical role and regional structure.
