The Efferent System of Cranial Nerve Nuclei: A Comparative by Prof. Dr. George Székely, Dr. Clara Matesz (auth.)

By Prof. Dr. George Székely, Dr. Clara Matesz (auth.)

A new procedure utilizing comparative neuromorphology is taken during this learn facing the association of the efferent nuclei of cranial nerves. The authors use the cobalt labelling strategy to establish neuron varieties and stick with their presence, or absence, in several animal species. They recommend a brand new category that's loose from a couple of controversies inherent within the classical class. the implications recommend that evolutionary adjustments within the middle and within the innervated periphary parallel one another with more and more advanced function.

18a). The first type can be found in the larger rostral two thirds of the nucleus. Neurons supplying the temporal, masseter and pterygoid muscles are mixed; however they can be distinguished by their size (Table 1). The tapering caudal one third is constituted solely by the second type of neuron (Fig. 6d). lm caudal to the nV in the ventrolateral motor column (Matesz and Szekely 1978). The caudal pole extends almost to the level of the nV (Fig. 18a), ventrally it is bordered by the large Mauthner neuron.

5a,b. The primary and secondary mandibular joints. Thick lines indicate articular facets. a Articular-quadrate joint of a generalized reptile. Arrows show the line of force of the closer and opener muscles. b The temporomandibular joint of a mammal (rodent). 2 The Secondary Mandibular Joint and Its Muscles Parallel with a series of complicated transformations (Crompton 1989), the articular-quadrate joint becomes the incudomalleolar joint and the temporomandibular joint evolves in its stead (Fig.

It is the derivative of the upper end of the hyoid arch and extends between the skin (tympanic membrane) and the perilymphatic cistern. In sauropsidia, a portion of the depressor mandibulae primordium is detached and forms the extracolumellaris muscle. It is innervated by the facial nerve and stretches the tympanic membrane. In mammals there are two muscles: the tensor tympani muscle innervated by the trigeminal nerve and the stapedius muscle supplied by the facial nerve. They have a very complex function in hearing by acting upon the ossicular chain.
