227 .205 Lecture Notes - Maxillary Sinus, Recurrent Laryngeal Nerve, Levator Labii Superioris
Document Summary
Affected is the buccinators muscle-function of the muscle: to return food back to the oral cavity. Denervation will cause collection of food in the oral vestibule. For mental nerve- innervates the lower lip and the chin. Slip tendon aside to get to the nerve. Ventral margin of the mandible and medial side of mandible. Mucus membrane lines sinus- these sinuses have goblet cells and cilia. -secrete mucus so it is always moist. Mucus membranes are similar to nasal cavity. Lined with mucosa similar to lining of nasal cavity. Communicate either directly or indirectly with nasal cavity. So secretions will be drained normally through the nasal cavity. 2)caudal maxillary sinus: rostral maxillary sinus, position of frontomaxillary opening between 1 and 2. The frontal sinus of the horse is undivided( unlike that of the cattle) Cattle frontal sinus is divided in to medial , intermediate , and lateral rostral frontal sinus.
