This study aimed to clarify the morphologic variations of the Martin-Gruber anastomosis (MGA) by tracing the anastomotic fascicles. We used 102 upper limbs, and MGA was found in 39.2%. Among 12 instances of MGA between the branches innervating the flexor digitorum profundus muscle, eight anastomotic branches solely innervated the muscle without crossover(More)
The aim of this study was to demonstrate the morphology of the quadratus plantae (QP) in relation to the tendinous slips of the flexor hallucis longus (FHL) and their surrounding structures, thereby providing data to understand function of the QP during gait, and for analyzing the movements of the foot and designing postoperative rehabilitation programs.(More)
The embryologic origin of the omohyoid muscle is different from that of the other neck muscles. A number of variations such as the absence of muscle, variable sites of origin and insertion, and multiple bellies have been reported. However, variations in the inferior belly of the omohyoid muscle are rare. There have been no reports of the combined occurrence(More)
The aim of this study was to clarify the morphologic and spatial relationships of the inferior bundle of the buccinator and the incisivus labii inferioris muscle (ILI) and their surrounding structures. The inferior bundle of the buccinator and the ILI were investigated in 40 hemifaces from Korean cadavers. The inferior bundle (or fourth band) of the(More)
The mentalis muscle (MT) is the only elevator of the lower lip and the chin, and it provides the major vertical support for the lower lip. However, there are few reports on the relationship between the MT and its surrounding muscles. The aim of this study was to clarify the morphology of the MT, especially in relation to the orbicularis oris muscle and the(More)
The number and arising sites of the rootlet comprising the intermediate nerve root were investigated in 100 sides of human brains. The arising sites of the rootlets were the pons halfway between the facial and vestibulocochlear nerves (31.9%), the arising portion of the vestibulocochlear nerve on the pons (28.8%) and the stem of the vestibulocochlear nerve(More)
The trajectory of the medial fibers of depressor anguli oris muscle that pass deep to the depressor labii inferioris muscle (dDAO) and the anatomic relationship have not yet been examined. The aim of this study was to clarify the arrangement of the dDAO and its relationships with the surrounding structures. The dDAOs were investigated in 40 hemifaces from(More)
An abnormal muscle was observed in the superficial region of the popliteal fossa during a dissection procedure conducted for medical students. This abnormal muscle originated from the biceps femoris tendon and inserted into the medial head of the gastrocnemius muscle. The innervating nerve branched from the lateral sural cutaneous nerve. The distributing(More)
The purpose of this study was to define the spinal root origins of the lower subscapular nerve and the amounts of participating nerve fibers from each spinal root and to discuss the clinical implications. Using a method of separating the nerve fascicles that traces the particular nerve fibers at the intrafascicular level, the spinal root origins of the(More)
Homeobox-containing genes consist of a large family of genes encoding transcription factor proteins. A motif of 60 amino acids termed the homeodomain (homeobox at the nucleotide level) has been intensively studied in order to elucidate the molecular mechanism of the specification of body pattern during normal development, differentiation, as well as(More)
