lamella

The head is also more or less connected by a thin plate of bone, the lamella, to another outgrowth, the processus longus.

The uppermost lamella of each ethmo-turbinal is larger than the others and more distinct.

A precisely similar arrangement is found in the scorpion gill-lamella, as seen in Fig. 69, A, taken from Macleod.

The white matter lies in the interior of the organ, and extends into the core of each lamella.

Between the epiblast and hypoblast a structureless lamella appears always to be interposed.
