Head and Neck Exam: Case Study 2

Hey guys,

This is in relation to the 2nd case study from the practice head and neck exam, the one where the patient coughs up the stone bur, and ingests it again as he swallows. It asks to describe what as happened and what you can expect to happen in the future.

For the first part I said when he first swallowed it the gag reflex prevented the bur from entering the body. The second time I said the reflex didn't react and he swallowed the bur, causing it to enter his digestive system (as the epiglottis closed entry to the larynx).

But what can we expect to happen in the future???

Hope the study is going well :D

Any help answering these questions would be great!!

Thanks

Thanks guys so much
Any help would be great we were getting confused. :D

Embryology again. :D

Hey again
1) can some one explain tome how the mesoderm is formed. coz i get that it is formed from the ectoderm but just a bit confused

2)nd jsut looking at one of the review shets we were given for embryolgy Human Bio 1OH review of session 1- there i a table for Q 2 that i am not sure how to fill out.
He has about the stages of prenatal development, the weeks of gestation for each and then has a column for embryonic form and orofacial development and im not really 100% sure what it means by embryonic form? i think with the oro-facial development we would just put what is occuring during that time. ? is this what others think or am i ocmpletely off track.

Thanks. :D
