چکیده انگلیسی
Comparative anatomy has shown similarities between reptilian and mammalian basal ganglia. Here the morphological characteristics of the medium spiny neurons (MSN) in the dorsolateral striatum (DLS) of the turtle are described after staining them with the Golgi technique. The soma of MSN in DLS showed three main forms: spherical, ovoid, and fusiform. The number of primary dendritic branches (3-4 dendrites/cell) was less than observed in mammals. The MSN axon originates mainly from the soma, and randomly it emerges at the beginning of the primary dendrite. The main differences between turtle and mammalian MSN were detected on dendritic spines. Short, thin, bifurcated and fungiform types of dendritic spines were observed in the turtle's MSN, according to their shape. In most of the analyzed spines, it was found that its length considerably exceeded that reported in mammals, with dendritic spines up to 8 μm in length. These differences could play an important role in the modulation of motor networks preserved along the vertebrate evolution.
