Structure and Origin - The tensor veli palatini muscle is thin and triangular in shape. - It arises from the scaphoid fossa of the pterygoid process of the sphenoid anteriorly. - It arises from the (medial aspect of the) spine of the sphenoid bone posteriorly. - It arises from the anterolateral aspect of the membranous wall of the pharyngotympanic tube. - Some muscle fibers may be continuous with those of the tensor tympani muscle. - No personal pronouns.

Insertion - Converges to form a tendon of attachment. - The tendon winds medially around the pterygoid hamulus. - Inserts into the palatine aponeurosis. - Inserts into the bony surface posterior to the palatine crest of the horizontal plate of palatine bone. - No personal pronouns.

Dilator Tubae Component - Some muscle fibers insert onto the lateral lamina of the cartilaginous part of pharyngotympanic tube. - Some muscle fibers insert onto adjacent connective tissue. - Some muscle fibers insert onto Ostmann's fat pad. - No personal pronouns.

Innervation - Receives motor innervation from the mandibular nerve (CN V). - Mandibular nerve is a branch of the trigeminal nerve (CN V). - Innervated via the nerve to medial pterygoid. - Not innervated by the pharyngeal plexus. - Formed by the vagal and glossopharyngeal nerves.
