what is epiphyses
cancellous/trabecular bone which occupies the end
what causes the force in muscle tissue

what do astrocytes do
support and ion transport
function of ogliodendrocytes
produces myelin
function of microganglia
provide immune surveillance
function of Schwann cells
produce myelin and support axons
layers of the GI tract
mucosa
submucosa
muscularis externa
serosa or adventitia
where is protective mucosa found
