VertexNormals is an option for graphics primitives which specifies the normal directions to assign to 3D vertices.
VertexQ
(Built-in Mathematica Symbol) VertexQ[g, v] yields True if v is a vertex in the graph g and False otherwise.
VertexReplace[g, {v_1 -> w_1, v_2 -> w_2, ...}] replaces each vertex v_i in the graph g by w_i.
VertexShape is an option and property for Graph and related functions that specifies the graphics used for vertices.
VertexSize is an option and property for Graph and related functions that specifies the size used for vertices.
VertexStyle is an option and property for Graph and related functions that specifies what style to use for vertices.
