The substance of which the nervous system is composed. It consists chiefly of albumen and a peculiar fatty matter, associated with phosphorus. There are two kinds of neurine-the one vesicular or consisting essentially of nerve vesicles or nerve cells or corpuscles, or, as they are sometimes called, from their prevailing in the ganglia-ganglion corpuscles and ganglion globules; the other, the tubular, formed-as the word imports-of tubules. The former is the cineritions or cortical nervous matter of the older anatomists ;-the latter, the white or medullary. The vesicular neurine has appeared to be restricted to the production and distribution of nerve-power; the tubular, to its conduction; yet the experiments of Dr. Brown-Sequard show, that the former conveys sensitive impressions from the posterior spinal roots to the brain.

Proto Oncogene Proteins c erbB 2
- cell surface protein-tyrosine kinase that is found to be overexpressed in significant number adenocarcinomas. It has extensive homology can heterodimerize EGF EPIDERMAL GROWTH FACTOR), 3 receptor (RECEPTOR, 3) and the 4 receptor. Activation of erbB-2 receptor occurs during heterodimer formation with a ligand-bound erbB family members. EC 2.7.11.-.
