  • Title: The longitudinal fibromuscular component of the soft palate in the fifteen-week human fetus: musculus uvulae and palatine raphe.
    Author: Langdon HL, Klueber K.
    Journal: Cleft Palate J; 1978 Oct; 15(4):337-48. PubMed ID: 281277.
    Abstract:
    The structural relationships of the longitudinal fibromuscular component of the soft palate (musculus uvulae and raphe) were studied using histologic sections from 19 early human fetal specimens. Musculus uvulae arises in association with the palatine aponeurosis near the beginning of the second quadrant of the velum, follows a sigmoid course, and terminates near the base of the uvula. In addition, an occasional muscular loop may arise from the bony palate, arch downwards, and then recur into the uvular muscle. A complex relationship exists between the raphe in the velum and several palatal muscles. With regard to musculus uvulae, small muscular bundles arise from the raphe to embrace the muscle near its crest. These branches may aid in contouring the dorsal surface of the velum in the region of the levator eminence to complement the surface of the posterior pharyngeal wall and thus enhance the efficiency of the velopharyngeal seal.
