    I have a few quick bio. questions....

    I read these in Schaum's and wanted to make sure they were correct...

    DERMIS arises from MESODERM (it is more of a connective tissue)
    NOTOCHORD arises from MESODERM
    ADRENAL CORTEX arises from ECTODERM (since it is in such close association with the sympathetic nervous system) even though the kidney itself originates from the mesoderm.

    Dermis=Meso
    Adernal cortex=Endo b/c it will be consider a gland and all the glands are endo
    Kidney= meso
    Notochord=Meso

    And do no forget that adernal medulla will be consider ecto since it is related to nervous system,hence it's secretions epinephrine and norepinephrine will stimulate sympathetic nervous system.

    Oh, right I meant to put adrenal medulla as arises from the ectoderm NOT the adrenal cortex (mesoderm)...sorry about that


    thanks and good luck to you too...

    I will post tomorrow at some point to let you know how it went and how I studied...
