They're occasionally loaded

Usage examples of bases.

From the curving inwards of the two lobes, as they move towards each other, the straight marginal spikes intercross by their tips at first, and ultimately by their bases.

These filaments, from their tips to their bases, are exquisitely sensitive to a momentary touch.

After a short time the glands, thus indirectly excited, transmit or reflect some influence down their own pedicels, inducing aggregation in cell beneath cell to their bases.

Their bases are broader, and besides their own vessels, they receive a fine branch from those which enter the tentacles on each side.

The stimulus proceeding from the glands of the disc acts on the bending part of the [page 20] exterior tentacles, near their bases, and does not (as will hereafter be proved) first travel up the pedicels to the glands, to be then reflected back to the bending place.

The process of redissolution travels upwards from the bases of the tentacles to the glands, and therefore in a reversed direction to that of aggregation.

The process of redissolution in all cases commences at the bases of the tentacles, and proceeds up them towards the glands.

Some force or influence must, therefore, be transmitted from the central glands to the exterior tentacles, first to near their bases causing this part to bend, and next to the glands causing them to secrete more copiously.

The process of redissolution commences at the bases of the tentacles, thence proceeding upwards to the glands.

Hence the only safe criterion, and to this alone I have trusted, is the bending inwards of the exterior tentacles, which have not been touched by the fluid, or at most only at their bases.

The protoplasm in the closely inflected tentacles was not in the least aggregated, but towards their bases it was collected in little brownish masses at the bottoms of the cells.

Yet curare caused very little aggregation in the cells of the tentacles, whereas nicotine and sulphate of quinine induced strongly marked aggregation down their bases.

When a gland is directly stimulated in any way, as by the pressure of a minute particle of glass, the protoplasm within the cells of the gland first becomes aggregated, then that in the cells immediately beneath the gland, and so lower and lower down the tentacles to their bases.

The protoplasm within the cells immediately beneath the glands are next affected, and so downwards from cell to cell to the bases of the tentacles.

Near the bases of the short central tentacles, the flattened or broad face is formed of about five longitudinal rows of cells.
