1. Which of the following explains why the digestive action of salivary amylase continues for some time after swallowing?

1.Neural crest cells give rise to
a)cells of renal medulla- ans:chromaffin cells of the adrenal medulla
b)cells of adrenal cortex
c)Preganglionic parasympathetic cell bodies
d)postganglionic sympathetic cell bodies
e)preganglionic sympathetic cell bodies


2.Best charac of STEROID hormones
1.stored in secretory granules
2.binds to intracellular receptors- ans: steroid hormones are lipophillic so they cannot be stored or preformed and pass through cell membranes of target cells.
3.synthesized in precursor form
4.act by generatin second messenger
5.usually transport unbound in plasma.

....
1.neural crest cells give rise to cells of the autonomic ganglia and only the post ganglionic nr fibres(whether symp/Parasym) would hav their cell bodies in the autonomic ganglia...
*Remember the choice given is "renal medulla" , not adrenal medulla , my friend....
