Item Study of the functional relationships between the buccinator muscle and the connective tissue of the cheek in humans(Annals of Anatomy, 2022) Martínez Sanz, Elena; Catón Vázquez, Francisco Javier; Maldonado Bautista, Estela; Murillo González, Jorge Alfonso; Barrio Asensio, María Del Carmen; Paradas Lara, Irene; García Serradilla, Moisés; Arráez Aybar, Luis Alfonso; Mérida Velasco, José RamónBackground: The buccinator muscle derives from the mesenchyme of the second pharyngeal arch. In adults, it has a quadrilateral shape, occupying the deepest part of the cheek region. Its function is complex, being active during swallowing, chewing, and sucking. To our knowledge, there are no studies that have specifically analyzed the relationship of the buccinator muscle fibers and neighboring connective tissue of the cheek in humans, neither during development nor in adults. Such relationships are fundamental to understand its function. Thus, in this study the relations of the buccinator muscle with associated connective tissue were investigated. Methods: The buccinator muscle region was investigated bilaterally in 41 human specimens of 8–17 weeks of development. Moreover, four complete adult tissue blocks from human cadavers (including mucosa and skin) were obtained from the cheek region (between the anterior border of the masseter muscle and the nasolabial fold). All samples were processed with standard histological techniques. In addition, subsets of sections were stained with picrosirius red (PSR). Furthermore, immunoreactivity against type I and III collagen was also studied in adult tissues. Results: The buccinator muscle showed direct relationships with its connective tissue from 8 to 17 weeks of development. Collagen fibers were arranged in septa from the submucosa to the skin through the muscle. These septa were positive for type I collagen and presented elastic fibers. Fibrous septa that were positive for type III collagen were arranged from the lateral side of the muscle to the skin. Conclusions: The intimate relationship between buccinator muscle fibers and cheek connective tissue may explain the complex functions of this muscle.- Project number: 114

Item Development of the Interosseous Muscles of the Human Hand: Morphological and Functional Aspects of the Terminal Insertion(Cells, tissues, organs, 2024) Maldonado Bautista, Estela; Martínez Sanz, Elena; Catón Vázquez, Francisco Javier; Arráez Aybar, Luis Alfonso; Barrio Asensio, María Del Carmen; Naredo, Esperanza; Murillo González, Jorge Alfonso; Mérida Velasco, José RamónIntroduction: To date, there have been no studies conducted on the development of interosseous muscles (IO) in the human hand. This study aimed to investigate the development of these muscles in order to clarify their terminal insertions and their relationship with the metacarpophalangeal joints. Methods: Serial sections of 25 human specimens (9 embryos and 16 fetuses) between the 7th and 14th week of development, sourced from the Collection of the Department of Anatomy and Embryology at UCM Faculty of Medicine, were analysed bilaterally using a conventional optical microscope. Results: Our findings revealed that, during the 7th week of development, the metacarpophalangeal interzone mesenchyme extended into the extensor apparatus of the fingers. Furthermore, we observed that the joint capsule and the tendon of the IO derive from the articular interzone mesenchyme. By the end of the 7th week, corresponding to Carnegie stage 21, the myotendinous junction appeared, initiating cavitation of the metacarpophalangeal joint. During the fetal period, the terminal insertions of the IO were identified: both the dorsal interosseous (DI) and palmar interosseous (PI) muscles insert into the metacarpophalangeal joint capsule and establish a connection with the volar plate located at the base of the proximal phalanx and the extensor apparatus. Some muscle fibres also attach to the joint capsule at the level of the proximal synovial cul-de-sac. The functional implications of these findings are discussed within this work. Conclusion: This study provides the first detailed description of the development of the interosseous muscles in the human hand.
