==Structure and Function==

==Structure and Function==

The soft palate is made of stiated palatine muscle and has very folded mucosa. It contacts the [[Epiglottis|epiglottis]] caudally.

The soft palate is made of striated palatine muscle and has very folded mucosa. It contacts the [[Epiglottis|epiglottis]] caudally.

==Musculature and Innervation==

==Musculature and Innervation==

The soft palate recieves sensation and taste from the glossopharyngeal ([[Cranial Nerves - Anatomy & Physiology|CN IX]]) nerve.

The soft palate transmits sensation and taste via the glossopharyngeal ([[Cranial Nerves - Anatomy & Physiology|CN IX]]) nerve.

The origin of the tensor velli palatini muscle is  near the tympanic bulla on the[[Skull and Facial Muscles - Anatomy & Physiology#Temporal Bone (os temporale)|temporal bone]]. The insertion site is the lateral aponeurosis. It tenses the soft palate.

===Levator velli palatini muscle===

===Levator velli palatini muscle===

The origin of the levator velli palatini muscle is near the tympanic bulla on the [[Skull and Facial Muscles - Anatomy & Physiology#Temporal Bone (os temporale)|temporal bone]]. The insertion site is the lateral aponeurosis. It raises the soft palate and recieves major innervation from the vagus nerve ([[Cranial Nerves - Anatomy & Physiology|CN X]]) and minor from the glossopgaryngeal nerve ([[Cranial Nerves - Anatomy & Physiology|CN IX]]).
