VM craniofacial development Flashcards
what process is this?
mandibular process
what process is this?
maxillary process
developing tooth -> dental lamina and tooth germ
meckel’s cartilage
tongue
palatal shelves
maxillary nerve trunk
what is this and its function?
nasal capsule
primitive support
dental lamina
what is this structure?
nerve trunk
no nuclei in axons as they are in cell bodies that are miles away in the trigeminal ganglion, nuclei we do see are supporting cells
what structures are derived from meckel’s cartilage?
Malleus, mandible, sphenomandibular ligament and sphenomalleolar ligament
what structures are derived from the nasal capsule?
Midline nasal septum and ethmoid bones
predict what age the embryo is, why?
Week 7 as palatal shelves down lateral tongue and tongue takes up most of the space
Week 6 is when see the first evidence of tooth development
compare the histology of the different structures
palatal shelves
tongue
