The following questions refer to the scenario below. A-1 Stampings, Inc., produces 14 metal stampings for the automotive industry.
The epithalamus comprises the habenular trigone, the pineal gland, and the habenular commissure. It is wired with the limbic system and basal ganglia. Species that possess a photoreceptive parapineal organ show asymmetry in the epithalmus at the habenula, to the left (dorsal).he epithalamus includes the habenula and their interconnecting fibers the habenular commissure, the stria medullaris and the pineal gland.
Functions of Epithelia. 1  Protection of underlying tissues. 2  Sensory reception via nerve endings/receptors. 3  Diffusion (movement of molecules down their concentration gradients) 4  Absorption (taking molecules into cells) Note role of Microvilli in pic above (to absorb) 5  Secretion (releasing molecules from cells)
