Neck: Soft Palate Flashcards
Tensor Palati Origin
Scaphoid fossa & Spine of sphenoid bone
Tensor Palati insertion
It hooks medially around pterygoid hamulus to form Palatine Aponeurosis
Tensor Palati Action
Makes the soft palate tense
Levator Palati origin
petrous bone in front of carotid canal & Auditory Tube
Levator Palati Insertion
Palatine Aponeurosis
Levator Palati Action
elevation of soft palate
Palatoglossus Origin
Palatine aponeurosis
Palatoglossus Insertion
Sides of Posterior part of tonuge
Palatoglossus Action
Elevation of Tongue and closure of oropharyngeal ithmus
Palatopharyngeus Origin
Palatine aponeurosis
Palatopharyngeus Insertion
posterior border of thyroid cartilage
Palatopharyngeus Action
elevation/ shortening of Pharynx
Musculus uvulae origin
- Posterior Nasal spine
- Palatine aponeurosus
Musculus uvulae Insertion
Mucousa of uvulae
Musculus uvulae Action
Elevation & retraction of uvulae, preventing eversion of soft palate
Motor innervation of soft palate
Pharyngeal Plexus (cranial root of accessory Nerve through Pharyngeal branch of vagus N)
- Except Tensor palati: which is supplied by Anterior division of mandibular Nerve through Nerve to medial pterygoid
Sensory Innervation of Soft Palate
- Lesser palatine N (branch of Greater palatine N of sphenopalatine ganglion)
- Glossopharyngeal N
Hard palate blood supply
Greater palatine Artery
Soft palate blood supply
- Lesser palatine Artery (from greater palatine A)
- Ascending palatine Artery (from Facial A cervical part)
- Ascending Pharyngeal A (from External Carotid A)
