Spinneret
Definition:
(n.) One of the special jointed organs situated on the under side, and near the end, of the abdomen of spiders, by means of which they spin their webs. Most spiders have three pairs of spinnerets, but some have only two pairs. The ordinary silk line of the spider is composed of numerous smaller lines jointed after issuing from the spinnerets.
Example Sentences:
(1) The proximal region of the gland is capable of protrusion through the prothoracic sternal slit as an elongate organ reaching upto the spinneret.
(2) PC12 cells, an immortalized cell line which secretes large amounts of dopamine, and dissociated bovine adrenal chromaffin cells, a non-dividing cell type which also secretes dopamine, were coextruded by a dry-jet wet spinning technique through a double-lumen spinneret from a 15% weight by volume solution of poly(acrylonitrile vinyl chloride) in either dimethylsulphoxide (DMSO), dimethylacetamide (DMAC) or dimethylformamide (DMF).
