|
||||
|---|---|---|---|---|---|
| Hyoid bone | Only one that is ossified of the skeletal elements in the visceral neck.
🗑
|
||||
| What is the investing fascia of the floor of the mouth called? | Geniohyoid fascia
🗑
|
||||
| Name derivatives of the 2nd arch | Syloid process, upper portion of hyoid bone and stylohyoid ligament
🗑
|
||||
| What muscle makes up the floor of the mouth? | Mylohyoid
🗑
|
||||
| Name muscles in the floor of the mouth | Anterior belly of digastrics and hyoglossus muscle which comes from the hyoid bone and goes to the tongue
🗑
|
||||
| What innervates the anterior belly of digastrics? Function? | Mylohyoid nerve: provides motor. Elevates hyoid bone and maybe a depressor of mandible
🗑
|
||||
| What innervates the posterior belly of digastrics? Attachment? | Facial nerve. Attaches to medial side of mastoid process
🗑
|
||||
| What innervates the stylohyoid muscle? Attachment? | Facial nerve. Attaches on styloid process
🗑
|
||||
| Where does the sternocleidomastoid muscle attach? | Lateral side of mastoid muscle
🗑
|
||||
| Submandibular gland | Has component that goes above mylohyoid. Contains cell bodies of PSNS nerve
🗑
|
||||
| Sublingual gland | Above the mylohyoid. Numerous tiny ducts that deliver saliva under the tongue along the ridge. Fold under tongue is there because of sublingual gland
🗑
|
||||
| Name branches of Mandibular Nerve | Inferior alveolar, Mylohyoid nerve, lingual, deep temporal, auriculotemporal, Masseteric and mental
🗑
|
||||
| Inferior alveolar nerve | Sensory for teeth
🗑
|
||||
| Mylohyoid nerve | Motor to anterior belly
🗑
|
||||
| Lingual nerve | Goes to tongue. Vehicle for delivering post-synaptic fibers into where they are going to be going into the gland
🗑
|
||||
| Deep Temporal nerves | Go to temporal
🗑
|
||||
| Auricolotemporal nerve | Delivers post-synpatic parasympathetic fibers from otic ganglion
🗑
|
||||
| Chorda Tympani | Comes out of ptetrotympanic fissure. Provides pre-synaptic parasympathetic fibers to submandibular ganglion. Sensory fibers they come from the anterior 2/3rds of the tongue taste buds. Taste fibers ride along with chorda tympani
🗑
|
||||
| Geniculate ganglion | For taste of anterior 2/3rds of tongue
🗑
|
||||
| Extrinsic muscles of tongue | Genioglossus muscle: Protrudes tongue, Hyoglossus muscle, Styloglossus and Palatoglossus (from soft palate) both retract tongue
🗑
|
||||
| Function of hyoglossus muscle | Pulls tongue down towards hyoid bone if tongue is contracted (depressor of tongue). If tongue is protruded, it will protract it and will be elevator of hyoid
🗑
|
||||
| Intrinsic muscles of tongue | Begin and end in tongue. They are interdigitating muscles going in all directions allowing tongue to take on many different shapes. Inferior longitudinal is most superficial
🗑
|
||||
| Hypoglossus nerve | Goes through hypoglossal canal and innervates tongue. To test integrity: Ask patient to stick tongue out. Will go to side of damage
🗑
|
||||
| Fauces | Separates the oral cavity from the pharyngeal cavity. Consists of Palatoglossal arch
🗑
|
||||
| What part of the tongue lives in oral cavity? and pharyngeal cavity? | Horizontal component lives in oral cavity. Vertical posterior 1/3rd lives in pharyngeal
🗑
|
||||
| What is the palatine tonsil a derivative of? | 2nd pharyngeal pouch
🗑
|
||||
| What is the eustacian tube a derivative of? | 1st pharyngeal pouch
🗑
|
||||
| Name branches of External Carotid Artery | Superficial temporal, Ascending pharyngeal, Lingual, Facial, Occipital, Posterior auricular, Maxillary, Superior thyroid (goes to voice box)
🗑
|
||||
| What do submandibular nodes drain? | Superficial area
🗑
|
||||
| Lymphatic drainage of the tongue | Tip of tongue drains to nodes outside of floor of mouth. Posterior, horizontal and vertical drains into jugular digastric nodes
🗑
