OBJECTIVES To obtain an accurate morphological description of the nerve that provides communication between the external laryngeal nerve and the recurrent laryngeal nerve in a large sample of human larynges. STUDY DESIGN Morphological study of human larynges. METHODS Microdissection of 103 human larynges obtained from necropsies was performed. Both the(More)
OBJECTIVES/HYPOTHESIS Current knowledge of the functional role of human laryngeal nerves is based on traditional laryngeal neuroanatomic descriptions or contradictory electromyographic studies. The aim of this study was to clarify the functional role of neural connections between laryngeal nerves by correlating the different electromyographic patterns(More)
Two cases with anomalous fascicles in abductor digiti minimi, noted in the course of dissecting 62 adult postmortem forearms, are described. Both fascicles arose from the flexor retinaculum and the antebrachial fascia; one was inserted into abductor digiti minimi and the other on the proximal phalanx of the 5th finger. The anomalous muscles crossed the(More)
A rare case of a four-headed biceps brachii muscle associated with a double piercing of one of the supernumerary heads by the musculocutaneous nerve was observed in the right arm of an 87-year-old female cadaver. One of the supernumerary heads of the biceps brachii originated from the humerus, in the area between the lesser tubercle and the coracobrachialis(More)
The larynx serves respiratory, protective, and phonatory functions. The motor and sensory innervation to the larynx controlling these functions is provided by the superior laryngeal nerve (SLN) and the recurrent laryngeal nerve (RLN). Classical studies state that the SLN innervates the cricothyroid muscle and provides sensory innervation to the supraglottic(More)
Changes in motoneurons innervating laryngeal muscles after section and regeneration of the recurrent laryngeal nerve (RLN) are far from being understood. Here, we report the somatotopic changes within the nucleus ambiguus (Amb) after the nerve injury and relates it to the resulting laryngeal fold impairment. The left RLN of each animal was transected and(More)
Neurons innervating the intrinsic muscles of the larynx are located within the nucleus ambiguus but the precise distribution of the neurons for each muscle is still a matter for debate. The purpose of this study was to finely determine the position and the number of the neurons innervating the intrinsic laryngeal muscles cricothyroid, posterior(More)
BACKGROUND Since the 18th century, the existence of ulnar nerve innervation of the medial head of the triceps brachii muscle has been controversial. The evidence for or against such innervation has been based on macroscopic dissection, an unsuitable method for studying intraneural topography or intramuscular branching. The study of smaller specimens(More)
