“…The observations in the field of blood supply to the brain, and consequently to the internal ethmoid artery, observed in our study coincide with those in the available literature on Caniformia (Depedrini & Campos, 2003; Frąckowiak, 2003; Frąckowiak & Zawidzka, 1990; Skoczylas et al, 2016; Tanuma, 1981; Wiland, 1967, 1991), Feliformia (Frąckowiak & Godynicki, 2003; Hsieh & Takemura, 1994; Klein, 1980; Takemura, 1982), Suiformes (Godynicki & Frackowiak, 1982; Jabłoński et al, 1989), Ruminantia (Frąckowiak et al, 2014; Frąckowiak & Jakubowski, 2008; Kiełtyka‐Kurc et al, 2015; König, 1979; Skoczylas et al, 2011; Zdun et al, 2013, 2019), Tylopoda (Al Aiyan et al, 2019; Kanan, 1970; Kiełtyka‐Kurc et al, 2014). The authors cited above confirm the presence of the internal carotid artery in Caniformia and Tylopoda throughout life.…”
