The soft palate (velum palatine) is located caudally to the [[Hard Palate|hard palate]]. It is comprised of muscle and is involved in tasting food and in [[deglutition]].

==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 [[Larynx - Anatomy & Physiology#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.

===Tensor velli palatini muscle===

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]]).

===Porcine===

===Porcine===

The soft palate does not contact the [[Epiglottis|epiglottis]] as the porcine soft palate is raised higher in the [[Oral Cavity Overview - Anatomy & Physiology|oral cavity ]] than in other species.

The tight laryngeal cuff around the laryngeal entrance, and therefore the soft palate cannot be raised for long periods of time and thus horses are nasal breathers. Laryngeal cuffing prevents [[control of Feeding - Anatomy & Physiology#The Vomit Reflex|vomiting]].
