Upper GI Tract
pharyngeal arch
- 1st
- frontonasal prominence develops into maxillae
- meet in midline
- develops into
- jaw
- maxilla
- mandible
- temperomandibular joint - connets mandibular fosa (skull) to codoyle (jaw)
- mandible connected to hyoid bone via small muscles
- = pull mandible down
- mandible connected to hyoid bone via small muscles
- temperomandibular joint - connets mandibular fosa (skull) to codoyle (jaw)
- palate
- inner ear bones
- incus
- malleus
- trigeminal nerve (cranial nerve 5) - enters via centre of pons ,leaves via foramina in sphenoid bone
- anterior cranial fosa = forms trigeminal ganglion
- V1 - opthalmic nerve
- supraorbital fissure
- orbit
- leaves frontal foramen
- orbit
- supraorbital fissure
- V2 - maxillary branch
- foramen rotundum
- infra orbital fissure floor
- maxillary foramen exit
- infra orbital fissure floor
- foramen rotundum
- V3 - mandibular branch (largest)
- foramen ovale
- pterygopalatine fossa
- otic ganglion
- temporalis muscle
- problem = weaker bite
- mssseter muscle
- pterygoid muscle
- lateral
- problem = cannot move jaw side to side
- medial
- lateral
- temporalis muscle
- otic ganglion
- pterygopalatine fossa
- foramen ovale
- V1 - opthalmic nerve
- anterior cranial fosa = forms trigeminal ganglion
- jaw
- develops into
- doesn't meet in midline
- = cleft plate - gap between palate and upper lip
- meet in midline
- frontonasal prominence develops into maxillae
- 2nd
- stapes develops
- the associated suscle stapedius
- innervated by facial nerve
- the associated suscle stapedius
- cranial nerve 7 develops
- = innervates facial muscles
- stapes develops
- 1st
swallowing
- bolus
- back of mouth
- soft palate closes of nasopharynx
- food down oropharynx
- larynx rises up, vocal chords close off trachea
- epiglottis depressed as food lands on it
- food into oesophagus
- into stomach via peristalsis
- food into oesophagus
- epiglottis depressed as food lands on it
- larynx rises up, vocal chords close off trachea
- food down oropharynx
- soft palate closes of nasopharynx
