A good agreement between a flux tube-based quark model of light baryons (strange and nonstrange) and the 1/N{sub c} expansion mass formula has been found in previous studies. In the present work a larger connection is established between the quark model and the 1/N{sub c} and 1/m{sub Q} expansion method by extending the previous procedure to baryons made of one heavy and two light quarks. The compatibility between both approaches is shown to hold in this sector too.
