Abstract

Aim

This study aims to explore the intramuscular innervation patterns of rectus extraocular muscles (REOMs) comprehensively. By supplementing existing knowledge using histological techniques to enrich current research findings, we endeavor to provide a holistic perspective on the complexities of REOM innervation.

Material and methods

Ten REOMs (superior, inferior, medial, and lateral) were collected from adult human cadavers of both sexes. All samples were carefully dissected to preserve muscle integrity and architecture and proceeded using H&E staining.

Results

Within each REOM, the intramuscular innervation is characterized by a dense network of motor sub-branches. Muscular sub-branches are distributed evenly within each REOM's mid-length cross-section.

Conclusions

In conclusion, the intramuscular innervation of the rectus extraocular muscles is a highly complex and organized system crucial for precisely controlling eyeball movements.

从组织学角度重新审视眼外直肌的肌内神经支配

目的本研究旨在全面探讨眼外直肌（REOM）的肌内神经支配模式。材料与方法从成年男性和女性尸体中采集了十块眼外直肌（上、下、内、外侧）。结果在每个 REOM 中，肌肉内神经支配的特点是运动亚分支网络密集。结论总之，眼外直肌的肌内神经支配是一个高度复杂和有组织的系统，对精确控制眼球运动至关重要。

期刊介绍： Translational Research in Anatomy is an international peer-reviewed and open access journal that publishes high-quality original papers. Focusing on translational research, the journal aims to disseminate the knowledge that is gained in the basic science of anatomy and to apply it to the diagnosis and treatment of human pathology in order to improve individual patient well-being. Topics published in Translational Research in Anatomy include anatomy in all of its aspects, especially those that have application to other scientific disciplines including the health sciences: • gross anatomy • neuroanatomy • histology • immunohistochemistry • comparative anatomy • embryology • molecular biology • microscopic anatomy • forensics • imaging/radiology • medical education Priority will be given to studies that clearly articulate their relevance to the broader aspects of anatomy and how they can impact patient care.Strengthening the ties between morphological research and medicine will foster collaboration between anatomists and physicians. Therefore, Translational Research in Anatomy will serve as a platform for communication and understanding between the disciplines of anatomy and medicine and will aid in the dissemination of anatomical research. The journal accepts the following article types: 1. Review articles 2. Original research papers 3. New state-of-the-art methods of research in the field of anatomy including imaging, dissection methods, medical devices and quantitation 4. Education papers (teaching technologies/methods in medical education in anatomy) 5. Commentaries 6. Letters to the Editor 7. Selected conference papers 8. Case Reports
