Quantifying Pain Location and Intensity with Multimodal Pain Body Diagrams
Published on: July 7, 2023
Summary
17th-century portraits commissioned by John Evelyn and William Petty featured skulls. These commemorative paintings served as reminders of mortality and marked significant life events for both men.
Area of Science:
- Art History
- Medical Humanities
- 17th-Century British History
Background:
- Explores the use of memento mori in 17th-century portraiture.
- Focuses on two prominent figures: John Evelyn and William Petty, founding fellows of the Royal Society.
- Examines commissioned portraits created in the mid-17th century.
Discussion:
- Analyzes the symbolic meaning of skulls in the portraits.
- Connects the portraits to personal milestones: Evelyn's engagement and Petty's anatomical appointment.
- Investigates the dual purpose of commemoration and mortality reflection in the artworks.
Key Insights:
- Skull symbolism in portraits served both personal commemoration and existential reflection.
- Art patronage by Royal Society fellows reflected intellectual and social currents of the era.
- Portraits functioned as complex visual statements on life, death, and status.
Outlook:
- Further research into other contemporary portraits with similar symbolism.
- Potential for interdisciplinary studies linking art, science, and philosophy.
- Understanding the enduring legacy of memento mori in visual culture.

Anatomy of the Intestines
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...

Skeletal Muscle Anatomy
Skeletal muscle is the most abundant type of muscle in the body. Tendons are the connective tissue that attaches skeletal muscle to bones. Skeletal muscles pull on tendons, which in turn pull on bones to carry out voluntary movements.
Anatomy of the Circulatory System
The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.
Anatomy of the Heart
The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.
Anatomy of the Heart
The heart is a hollow, muscular organ approximately the size of a fist, consisting of four chambers. It is enclosed in the pericardium, a fibrous sac with two layers: the visceral and parietal pericardium, separated by a fluid-filled space containing serous fluid to reduce friction.
The heart has three layers: the innermost endocardium, the muscular myocardium, and the outer epicardium, all working together for optimal cardiac function.

Anatomy of Blood Vessels
The vascular system, an integral part of the circulatory system, comprises various blood vessels that play crucial roles in maintaining the body's homeostasis. These blood vessels form a complex and efficient circulatory network. The three primary categories of blood vessels are the arteries, veins, and capillaries.
Arteries
Arteries circulate oxygenated blood from the heart, except the pulmonary artery, which transports deoxygenated blood to the lungs. Large arteries, such as the aorta, have...
