The International Journal of Morphology (Revista Internacional de Morfología) (Print ISSN 0717-9367; Online ISSN 0717-9502) is an official publication of the Chilean Society of Anatomy, Argentine Association of Anatomy and Pan American Association of Anatomy. It is the continuation of Revista Chilena de Anatomía (Chilean Anatomical Journal) and is published bimonthly. The six issues published yearly constitute one volume. This journal covers morphology in all its aspects, Gross Anatomy, Histology and Developmental Biology, as well as human and animal morphological aspects, including Celular, Molecular, systems or Evolutionary Biology. Reviews, short and brief communications and Letters to the Editor are also accepted.

All articles submitted to International Journal of Morphology must be original. In a letter to the Editor, signed by all the authors, it should be expressly declared that the manuscript must be approved by all authors, may not have been published or previously sent either in full or a part thereof, except in abstract form, and may not be under consideration by any other journal. All authors of manuscripts submitted should complete the “Author Responsibility Statement” form which is in accordance with the recommendations of the International Committee of Medical Journal Editors (, regarding authorship criteria.

For authors from countries whose language is different from English, an english translation certificate of the manuscript, issued by a native translator, must also be attached.

Compliance with ethical standards

To guarantee objectivity and transparency in the investigation and to ensure that the accepted principles of ethical and professional conduct have been followed, in studies on human beings and experimental animals, the authors must submit copies of the research approval document issued by the Scientific Ethics Committee.In addition, the authors must include information on sources of financing and possible conflicts of interest, using a form available on the website of the International Committee of Medical Journal Editors ( (“Uniform Disclosure Form for Possible Conflicts of Interest”).
  1. Research in Humans

Any research involving human participants must have been approved by the Scientific Ethics Committee, and must have been conducted in accordance with the principles expressed in the Declaration of Helsinki. The authors must submit, upon request, a statement from the Institutional Review Board or an equivalent Ethics Committee indicating the research’s approval. We reserve the right to reject any work that we believe has not met a high ethical standard, even when formal approval has been obtained.

Subjects must receive proper instruction, and consent their participation by signing the appropriate informed consent document. If the consent was verbal rather than written, or if it could not be obtained, the authors must explain the reasons in the manuscript, and the use of verbal consent or lack of consent must have been approved by the Institutional Review Board or equivalent Scientific Ethics Committee.

All efforts should be made to protect the patient’s privacy and anonymity. Identifying information, including photos, should not be included in the manuscript unless that information is crucial and the person has given written consent. More information about patient privacy, anonymity and informed consent can be found in the International Committee of Medical Journal Editors website ( (“Privacy and Confidentiality Guidelines”).

The Material and Method section of the article on research using human subjects or samples must include ethical statements that specify the following:

  • The name of the Institutional Review Board or equivalent Scientific Ethics Committee that approved the protocol and the associated permit number(s). If approval was not obtained, authors should provide a detailed statement explaining why this was not necessary.
  • If informed consent was obtained verbally, it should be indicated in the manuscript:
    • Why the written consent could not be obtained?
    • The approval of the use of oral consent by the Institutional Review Committee or equivalent Scientific Ethics Committee.
    • How oral consent was documented.
  • For studies involving human beings categorized by race/ethnicity, age, disease/disability, religion, sex/gender, sexual orientation or other socially constructed groups, authors should:
    • Explicitly describe the methods of categorizing human populations.
    • Define categories in as much detail as the study protocol allows.
    • Justify choices of definitions and categories, for example, if a funding agency required some human categorization rule.
    • Explain whether (and if so, how) confounding variables were controlled, such as socioeconomic status, nutrition, environmental exposures, or similar factors in the analysis.
  • Also, obsolete terms and potentially stigmatizing labels should be changed to more current and acceptable terminology. Examples: “cancer victims” should be changed to “cancer patients”.
  1. Research in Animals

All research involving vertebrates or cephalopods must have the approval of the Institutional Review Committee or equivalent Scientific Ethics Committee, and must have been conducted according to the National and International guidelines that apply. Approval must be received before beginning of the intervention.

Manuscripts reporting on animal research should be included in the Material and Method section:

  • The full name of the Scientific Ethics Committee that approved the research protocol and the associated permit number(s).
  • Where ethical approval is not required, the manuscript should include the reasons why (“according to the relevant regulations, the study is exempt from the approval requirement”).
  • Relevant details of steps taken to improve animal suffering.

Example of an ethical statement:

This study was conducted in strict accordance with the recommendations of the National Institutes of Health’s Guide for the Care and Use of Laboratory Animals. The research protocol with animal experimentation was approved by the Scientific Ethics Committee of University XXXXX (Protocol Number: 00-0000). All surgery was performed under sodium pentobarbital anesthesia and every effort was made to minimize suffering.

Humanitarian Endpoint

Manuscripts reporting on studies in which the death of an animal (vertebrate, cephalopod) is a probable outcome or a planned experimental endpoint, must provide detailed information on the details of the study design, the rationale for the approach and methodology, including consideration of humanitarian endpoints. This applies to research involving, for example, the evaluation of survival, toxicity, longevity, terminal illness, or high incidental mortality rates.

Definition of humanitarian endpoint

A humanitarian endpoint can be defined as “the earliest indicator of (possible) pain and/or suffering in an animal experiment that, within a context of moral justification and scientific endpoints to be achieved, can be used to avoid or limit pain and/or suffering by acting with measures, such as humanitarian sacrifice or relief from pain and suffering” (Hendriksen & Morton, 1999). Please refer to the NC3Rs guidelines for more information.

Manuscripts peer review

The manuscripts will be subject to evaluation by the Editing Committee and the Scientific Council. The review will be carried out by two evaluators, members of the Editing Committee and/or the Scientific Council, and ad hoc advisors specialized in the field of study of the article. The specialists in the subject matter will determine if the article may a) be published; b) be published with modifications or c) is rejected. A copy of the determination will be sent to the first author or corresponding author.

Form and preparation of manuscripts

Manuscripts should be as concise as possible (no more than 12 pages long, including text, illustrations, and References).

The manuscript should be prepared in Word format, in letter-size, use Arial font, size 12, spaced 1.5 pt, with a 3 cm margin.

Manuscripts must be sent by email (Text and Tables in separate word format and Figures in jpg format, at least 300 dpi and in separate files).

In human and experimental animal studies, authors must submit a copy of the Institutional Ethics Committee approval. Should the Journal consider it necessary, it will request the informed consent form (see above “Compliance with ethical standards”).

Only manuscripts written in English and Spanish will be considered. They should be organized as follows: Title Page, Summary and Key Words, Introduction, Material and Method, Results, Discussion, Summary and Key Words in Spanish (the summary translation will be realized by the journal), Acknowledgments, and References.

  • Title page: should include: title, full name of author(s), institutional affiliation with complete address, the name, address, telephone number and e-mail address of the corresponding author; at the end of each author’s name, the name of the Department and Institution to which each author was associated during execution of the research work must be identified in Arabic numerals, in superscript. If the manuscript was subsidized, indicate the sponsorship or grant and process number at the bottom of the page.
  • Summary (structured): should not exceed 300 words and should be formatted to serve in lieu of a concluding summary. It should refer concisely to the rest of the paper. Key words: 3 to 5 key words of the MeSH Headings (Medical Subject Headings –
  • Text: Introduction, Material and Method, Results and Discussion.
  • Tables and Figures: Each table must have a self-explanatory title, be numbered in order of appearance with Roman numerals, and be cited at an appropriate point in the text. Tables should present comparisons of data that are too cumbersome to describe in the text. Figures are numbered with Arabic numeral (Figures are all Illustrations that are not Tables, graphics, x-ray images, presentations, etc.).

Abbreviations used in figures should be defined in the legend and must match exactly those used in the text. If necessary, use letters, numbers or transferable symbols.

  • Acknowledgments: Contributors who do not meet the authorship criteria should be mentioned in this section. It is expected that those who have been recognized have given their permission to be named.
  • References: Maximum 25 references. Text references to literature should be arranged alphabetical by author’s last name, following the standards of the journal’s technical format. Every author should be named in the References. In the text, when there are more than two authors, use the first author’s name and et al. accompanied by the year of publication in parenthesis. When references are made to more than one paper by the same author, published in the same year, refer them to as a, b, c, etc., along with the year of publication in parenthesis. The year should be repeated in each citation if the author has more than one article mentioned.
