Anatomical studies on the pudendal nerve in the Indian buffalo (Bubalus bubalis). 1980

P Prakash, and G S Rao, and R K Ghosh

This is a study of the origin, formation, course and distribution of the pudendal nerve (N. pudendus) in the Indian buffalo (Bubalus bubalis). The pudendal nerve originates from the union of the ventral rami of the 2nd, 3rd and 4th sacral spinal nerves. The largest contribution comes from the 3rd sacral nerve (13,284 +/- 844.45 fibres). The number of fasciculi, their area and arrangement, the total fibre count and the diameter spectra of the myelinated nerve fibres in N. pudendus and its rami have also been studied. There are as many as 7-98 fascicles at different levels of this nerve. The mean value of the area of the fascicles ranges from 0.244-4.684 mm2. The histograms of the myelinated nerve fibres are unimodal at all the selected levels with a peak around 2-4 micrometer. Of the myelinated fibres 72.47-86.72% are in the range of 2-4 micrometer.

D009413	Nerve Fibers, Myelinated	A class of nerve fibers as defined by their structure, specifically the nerve sheath arrangement. The AXONS of the myelinated nerve fibers are completely encased in a MYELIN SHEATH. They are fibers of relatively large and varied diameters. Their NEURAL CONDUCTION rates are faster than those of the unmyelinated nerve fibers (NERVE FIBERS, UNMYELINATED). Myelinated nerve fibers are present in somatic and autonomic nerves.

D010413	Penis	The external reproductive organ of males. It is composed of a mass of erectile tissue enclosed in three cylindrical fibrous compartments. Two of the three compartments, the corpus cavernosa, are placed side-by-side along the upper part of the organ. The third compartment below, the corpus spongiosum, houses the urethra.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
