L4 Anatomy of Ingestion Flashcards
Bones forming the Hard Palate?
The hard palate is formed by:
Maxillary bones: incisive bone and palatine processes (ANTERIORLY)
Palatine bones: horizontal processes (POSTERIOR)
Soft Palate is made of up muscles connected to ________.
It is connected to the hard palate by _____________.
Soft Palate is made of up muscles connected to mucous membrane.
It is connected to the hard palate by aponeurosis
Where does the soft palate join the Toungue and Pharynx?
palatal arches: helps form palatoglossal and nasopharyngeal seals
_________ tenses Soft Palate
Tensor velipalatini tenses SP
________ elevates Soft Palate
Levatorvelipalatini elevates SP
_______ elevates tongue & draws SP to tongue
Palatoglossus elevates tongue & draws SP to tongue
__________ pulls walls of pharyx against Soft Palate
Palatopharyngeus pulls walls of pharyx against SP
___________ shortens & broadens uvula
Musculus uvulae shortens & broadens uvula
- Tensor velipalatini tenses SP
- Levatorvelipalatini elevates SP
- Palatoglossus elevates tongue & draws SP to the tongue
- Palatopharyngeuspulls walls of pharyxagainst SP
- Musculus uvulae shortens & broadens uvula
Largest Salivary Gland?
Its secretion composition?
Parotid Gland
Mostly serous secretions (serous acini)
Parotid Gland Location?
Parotid Gland Location
- Inferior to external auditory meatus (EAM)
- Anterior to sternocleidomastoid muscle (SCM)
- Posterior to ramus of mandible
Autonomic Wiring of the Partotid Gland?
Glossopharyngeal Nerve Synapses on Otic Ganglia
What is Frey’s syndrome?
Damage to Parasympathetic nerves of the pharynx
Nerve regrowth synapses onto sweat glands => parasympathetic signaling for stimulation of salivary production leads to Gustatory sweating
The Parotid Duct is superficial to the _______ and can be palpated, turns medially and passes through the ______ muscle.
The Parotid Duct is superficial to the masseter and can be palpated, turns medially and passes through the buccinator muscle.
Salivary gland with mixed serous and mucous secretions?
Submandibular Gland: Superficial (larger)and deep lobes
Opening of Submandibular Duct
Salivary glad with Higher mucin content in secretions?
Sublingual Glands
- 18-20 glands
- Most drain via sublingual fold openings
Nasopharyx communicates with nose via ______
Nasopharyx communicates with nose via choanae
________ areas associated with Otitis Media
Pharyngeal (adenoids) and tubal tonsils
_________________ muscle opens Eustachian tube during swallowing
Salpingopharyngeus muscle opens Eustachian tube during swallowing
What holds a bolus in the mouth during chewing?
Glossopalatal Seal
Pharyngeal Muscles: Circular vs. Longitudinal
Innervation of Pharyngeal Muscles?
Motor vs. Sensory?
MOTOR
Pharyngeal Branch of the Vagus nerve (CN X) for Superior, Middle, Inferior Constrictors, Salpingopharyngeus, and Palatopharyngeus
Glossopharyngeal Nerve (CN IX) for Stylopharyngeus
SENSORY
Glossopharyngeal for all
Muscles involved in Palatoglossal Seal facilitated by ______ and ______Nerves
Muscles involved in Palatoglossal Seal facilitated by Hypoglossal (XII) and Vagus (X) Nerves
