Abdominal Exam IV: Acute Abdominal Pain Assessment

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...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Human color vision is impressive. People with normal color vision can tell apart millions of individual hues. Most amazingly, this ability is achieved with fairly simple hardware. Part of the power of human color vision comes from a clever bit of engineering in the human brain. There, color perception relies on what is known as an 'opponent system.' This means that the presence of one kind of stimulus is treated as evidence for...

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...

Color in Coordination Complexes When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.

Training Synesthetic Letter-color Associations by Reading in Color

2014
Reading in color is a new method for training letter-color associations that are typically found only in grapheme-color synesthetes. It involves an implicit form of training that has potential for long-term associative training methods because the training is a byproduct of reading and any text can be colored.
FAQs
Abdominal color patterns reflect three linked processes: pigments must be produced, distributed through abdominal tissues, and modified in ways that affect their visible appearance. Genetic regulation establishes part of this developmental program, while environmental conditions can influence intensity or arrangement. Studying these influences helps connect visible traits with development and adaptation.
The visible pattern is not determined by genetics alone. Developmental processes shape how pigmentation appears in abdominal tissues, while environmental conditions may alter its intensity or arrangement. This interaction gives researchers a way to examine how inherited regulation and surroundings jointly affect a color trait during biological development.
Abdominal coloring can serve as a visual signal whose meaning depends on the biological context. Camouflage may reduce visual detection, whereas warning coloration can communicate a potential risk; other patterns may participate in communication linked to sexual selection or mimicry. Examining these alternatives helps researchers relate appearance to survival, behavior, and ecological pressures without assuming one function for every pattern.
Researchers use comparative observations and imaging to examine abdominal pigmentation, visible patterns, intensity, and arrangement. They can compare these features across organisms and relate the results to species identification, classification, behavior, or ecology. The same approach also supports evolutionary analysis by showing how color traits vary and how those differences may correspond to ecological pressures.
Researchers can compare pigmentation and pattern arrangement among animals to support species identification and classification. These traits provide visible characters for distinguishing organisms, while associated observations may also contribute to behavioral research. In this way, abdominal features connect descriptive identification with broader biological questions about variation, ecology, and the relationship between appearance and survival.
Comparing abdominal color traits across animals can reveal how ecological pressures shape visible variation. Researchers can investigate whether patterns relate to camouflage, warning signals, mimicry, or sexual selection, then consider those relationships in the context of adaptation. This makes abdominal coloring a useful trait for connecting observable differences with evolutionary and ecological explanations.
