Henry Vandyke Carter, MD
(1831 – 1897)

English physician, surgeon, medical artist, and a pioneer in leprosy and mycetoma studies.  HV Carter was born in Yorkshire in 1831. He was the son of Henry Barlow Carter, a well-known artist and it is possible that he honed his natural talents with his father. His mother picked his middle name after a famous painter, Anthony Van Dyck. This is probably why his name is sometimes shown as Henry Van Dyke Carter, although the most common presentation of his middle name is Vandyke.

Having problems to finance his medical studies, HV Carter trained as an apothecary and later as an anatomical demonstrator at St. George’s Hospital in London, where he met Henry Gray (1872-1861), who was at the time the anatomical lecturer. Having seen the quality of HV Carter’s drawings, Henry Gray teamed with him to produce one of the most popular and longer-lived anatomy books in history: “Gray’s Anatomy”, which was first published in late 1857.  The book itself, about which many papers have been written, was immediately accepted and praised because of the clarity of the text as well as the incredible drawings of Henry Vandyke Carter.

While working on the book’s drawings, HV Carter continued his studies and received his MD in 1856.

In spite of initially being offered a co-authorship of the book, Dr. Carter was relegated to the position of illustrator by Henry Gray and never saw the royalties that the book could have generated for him. For all his work and dedication, Dr. Carter only received a one-time payment of 150 pounds. Dr.  Carter never worked again with Gray, who died of smallpox only a few years later.

Frustrated, Dr. Carter took the exams for the India Medical Service.  In 1858 he joined as an Assistant Surgeon and later became a professor of anatomy and physiology. Even later he served as a Civil Surgeon. During his tenure with the India Medical Service he attained the ranks of Surgeon, Surgeon-Major, Surgeon-Lieutenant-Colonel, and Brigade-Surgeon.

Dr. Carter dedicated the rest of his life to the study of leprosy, and other ailments typical of India at that time. He held several important offices, including that of Dean of the Medical School of the University of Bombay. In 1890, after his retirement, he was appointed Honorary Physician to the Queen.

Dr. Henry Vandyke Carter died of tuberculosis in 1897.

Personal note: Had history been different, this famous book would have been called “Gray and Carter’s Anatomy” and Dr. Carter never gone to India. His legacy is still seen in the images of the thousands of copies of “Gray’s Anatomy” throughout the world and the many reproductions of his work available on the Internet. We are proud to use some of his images in this blog. The image accompanying this article is a self-portrait of Dr. Carter. Click on the image for a larger depiction. Dr. Miranda

Trabeculae carnae

The trabeculae carnae is a meshwork of fleshy cords found in the inner aspect of the right and left ventricles of the heart.

The Latin term [trab] means "beam", and [trabeculum] refers to the group of beams that supports a roof, like an intertwined network.  The plural for of [trabeculum] is [trabeculae].

The second term [carnae] is Latin for "meaty". The meaning of [trabeculae carnae] is the "meaty meshwork".

The trabeculae carnae are more evident and larger in the left ventricle than in the right ventricle, and larger and more complex towards the cardiac apex.  The accompanying image shows the dissection of a human heart exposing the trabeculae carnaes in the right ventricle.

-nym-

Although not a medical root term, the root [-nym-] arises from the Greek [onoma] meaning "name". There are many terms that incorporate this root:

Eponym: Use of a proper name to denote a structure
Eunym: [Eu-] is a prefix that means "good", so it imeans a "good name". Also written as "euonym"
Homonym: Same name
Synomym: "A name with the same sense, or same meaning"
Antomym: From the Greek [ant- and anti] meaning opposite. An opposite name
Anonym: From the Greek [an- and ano-] meaning "without". Without a name (anonymous)
Pseudonym: From the Greek [Pseudo-] meaning "false". A false name
Toponym: From [topos], meaning place. The name of a place or location


Henry Koplik, MD


This article is part of the series "A Moment in History" where we honor those who have contributed to the growth of medical knowledge in the areas of anatomy, medicine, surgery, and medical research.To search all the articles in this series, click here.

Henry Koplik, MD (1858 -1927). American pediatrician and researcher, was born in 1858 in the city of New York.  He received his MD from the College of Physicians and Surgeons at the Colombia University in New York. He spent several years studying in Berlin, Vienna, and Prague. Upon his return to the US he worked at the lower Manhattan Good Samaritan dispensary, where he later built a large pediatric outpatient clinic which became a model for the care of infants and children. In fact, under Dr Koplik's direction, this clinic became the world's first "milk depot" providing fresh milk and infant food for underprivileged mothers in the area. Dr. Koplik was one of the founders of the American Pediatric Society, and was one of its presidents.

Mostly remembered by the pathognomonic and eponymic "Koplik's spots", Dr Koplik had many other achievements. Some of them include the prophylaxis of a milk depot, the strict discipline in diagnosis and care of the pediatric patient,  the discovery of the bacillus responsible for whooping cough, the prevention of cross-contamination at a pediatric ward, etc.

Dr. Koplik wrote a number of clinical and research papers on hygiene and public health, as well on a number of medical topics, plus a book on "Diseases of Infancy and Childhood".

-cis-

This is a medical root term with a Latin origin and means "to cut". There is a corresponding Greek suffix [-otome], or [-otomy] that has a similar meaning. Uses of this term include:

Incision : "To cut in"
Incisive: Something that "cuts in"
Incisor: Refers to a type of tooth that has a "cutting in" action
Excision: The prefix [ex-] means "out" or "outside". To cut out, or to extirpate. See the meaning of the suffix [-ectomy] here
Circumcision: The prefix [circum-] means "around", or "in a circle". To cut around (in a circle)


Aortic arch

The aortic arch is a segment of the aorta that arches from the midline towards posterior and to the left. It presents with three branches. From proximal to distal they are the brachiocephalic trunk, the left common carotid artery, and the left subclavian artery. There are several anatomical variations of the branches of the aortic arch.

There is no clear anatomical landmark to denote the ending of the ascending aorta and the beginning of the aortic arch, as there is no clear anatomical landmark to denote the ending of the aortic arch and the beginning of the descending aorta. Anatomists use as a reference a horizontal plane that passes through the angle of Louis. Since this plane also separates the inferior from the superior mediastinum, the aortic arch is found in the superior mediastium, while the ascending and descending aorta are found in the inferior mediastinum.

The aortic arch has anatomical relations with the bifurcation of the trachea, the pulmonary trunk and its bifurcation, and the left brachiocephalic vein. In its inferior surface, the aortic arch in the adult has the embryological remnant of the ductus arteriousus, called the ligamentum arteriosum.

The term "aortic arch" was coined and first used by Lorenz Heister (1683 1785)

-angi-

This is a medical root term that originates from the Greek and means "vessel", as in a "container". The term is commonly misunderstood to mean "artery". The original meanings of the term in early Greek and Roman medicine where multiple. It was Lorenz Heister (1683-1758) who first used the term in its modern meaning. Applications of this root term include:

Angiology: Study of vessels
Angioma: Vessel tumor or mass, usually referred to a malformation of knotted vessels. The plural form is "angiomata"
Angioplasty: Reshaping of a vessel
Angiitis: Inflammation of a vessel. Note the double "i" in the word. This is the correct form of the term. "Angitis" is not correct!
Angiogenesis: Creation or generation of vessels
Neoangiogenesis: The prefix [neo-] means [new], therefore the term means "creation or generation of new vessels"
Cholangiogram: The prefix [chol-] means "bile", while the suffix [-ogram] means "examination of". A [cholangiogram] is the "examination of a bile vessel"
Cineangiogram: The prefix [cine-] means "movement", although we use it to mean "movie", while the suffix [-ogram] means "examination of". A [cineangiogram] is the "examination of a vessel in movement"
