chk this site ----- http://med.fsu.edu/gsm/ma/chapters/dental/118600.htm
when u see hypomineralized in the question think of enamel lamellae or enamel tufts .here as the q says to the enamel surface then it has to be lamellae.

as for the second q ----
Muscularis Mucosae
The muscularis mucosae, a thin layer of smooth muscle, forms the border between the mucosa and submucosa. It consists of outer longitudinal and inner circular fibres; from the inner layer strands of smooth muscle cells extend through the lamina propria toward the luminal surface between the gastric glands. It is surmized that contraction of these strands may compress the glands, thereby facilitating their emptying (Bloom and Fawcett l975).

hope i could help u dont worry abt the exam u can do it!!!!!! keep ur fingers crossed and god will surely help u .

in the hypomineralised question

if the choice is enamel tuft it is little more confusing ,it is hypomineralised but doesnt extend to surface ,resembeles,tufts of grass

enamel lamella /extends to surface fully /caries chance is high too

muscularis mucosa/esophagus

UPPER motor neuron lesion and lower motor neuron lesion thats what it is
