Transcript
The floor of the oral cavity is formed by m. mylohyoideus and m. genoiglossus. N. facialis contributes to the sensory innervation of the tongue, because the copula is a derivative of the 2nd pharyngeal arch. Pylorus of the stomach is located retroperitoneally at the L1 level, and contains mucous glands within tela submucosa. The parasympathetic innervation of the small intestine is provided by nervus vagus, the sympathetic innervation by nervi splanchnici. Omentum majus consists of 4 layers of peritoneum and is a derivative of a dorsal mesogastrium. Caecum and colon ascendens, innervated by n. X., are derivatives of the hindgut. The liver develops as a bud from the proximal part of a midgut and is supplied by a. hepatica propria.
