采用组织学和组织化学方法对舌肌进行了形态学研究。通过后者的附件和纤维课程的解剖学重新评估。肌原纤维腺苷三磷酸酶（mATPase），琥珀酸脱氢酶，NADH黄递酶，磷酸化酶，酯酶，糖原和脂质染色切片进行组织化学研究。鉴定了I型和II型纤维，后者被细分为II 1（高度糖酵解）、II 12（中度糖酵解和脂解）和II 123（高度脂解）。在外在肌中，19-25%的纤维为I型（平均直径27微米），75-81%的纤维为II型（37微米）;三个II型亚组的比例相等，各占总纤维量的22-30%。上级肌舌骨舌和尿道下肌茎突舌仅含有II型纤维，主要为II 12型（分别为67%和46%），直径与m相似。舌骨舌肌和肌茎突舌肌内在肌也完全由II型纤维（23微米）组成。m以II 123纤维为主。verticalis（83%）的纤维成分中，H_（12）仅占10%，II_（11）仅占6%;横动脉更为平衡：37% II 1型、32% II 12型和31% II 123型。
The morphology of the tongue muscles was studied by in situ dissection as well as by histological and histochemical methods. By means of the latter an anatomical reassessment of attachments and fiber courses was made. The histochemistry was studied in sections stained for myofibrillar adenosine triphosphatase (mATPase), succinic dehydrogenase, NADH diaphorase, phosphorylase, esterase, glycogen and lipids. Fibers of type I and type II were identified, and the latter were subdivided into II1 (highly glycolytic), II12 (intermediately glycolytic and lipolytic) and II123 (highly lipolytic). In the extrinsic muscles, the fibers were 19-25% type I (mean diameter 27 micrometers) and 75-81% type II (37 micrometers); the three type II subgroups appeared in equal proportions, each accounting for 22-30% of the total fiber amount. Pars longitudinalis superior m. hyoglossi and pars longitudinalis inferior m. styloglossi contained only type II fibers, mainly type II12 (67% and 46%, respectively), of diameters like those in m. hyoglossus and m. styloglossus. The intrinsic muscles also consisted entirely of type II fibers (23 micrometers). II123 fibers predominated in m. verticalis (83%), which has only 10% H12 and 6% II1, whereas the fiber composition of m. transversus was more balanced: 37% type II1, 32% II12 and 31% II123.
