A gap between the upper border of the superior constrictor and the skull base This gap is occupied by the pharyngobasilar fascia. It gives passage to the levator palati, ascending palatine artery, and auditory tube. 🤟 2. A gap laterally between the superior and middle constrictors It gives passage to the following: ✌️ a. Stylopharyngeus b. Glossopharyngeal nerve 3. A gap laterally between the middle and inferior constrictors This gap is closed by the thyrohyoid membrane. The structures passing through this gap are: ✌️ a. Internal laryngeal nerve. b. Superior laryngeal artery. 4. A gap between the two parts of the inferior constrictor It is a weak area at the back of the pharynx called Killian’s dehiscence. 5. A gap at the lower border of the inferior constrictor, pierced by: ✌️ a. Inferior laryngeal artery. b. Recurrent laryngeal nerve. 𝐌𝐂𝐐: 🤔💪 👋 1.
