Connective appendage

Functional Groups and Appendages as Keys for Connective Transforms.71... 

A pair of appendages which are in spatial proximity suggests the application of connective transforms, even if such appendages are not functionalized. Typical of retrosynthetic connections of this type are those shown for targets 201 and 202. ... 

Algorithms for machine-generated syntheses by application of connective transforms to target structures containing appendages, medium-sized rings, etc. have been described. ... 

Arteries entering the skin arise from more substantial vessels located in the subcutaneous connective tissue. These offshoots form a plexus just beneath the dermis [11]. Branches from this subcutaneous network directly supply blood to the hair follicles, the glandular appendages, and the subcutaneous fat. Branches to the upper skin from this deep plexus divide again within... 

FIGURE 1-17 The surfaceofan ependymal cell contains basal bodies (arrows) connected to the microtubules of cilia, seen here in longitudinal section. Several microvilli are also present. X37,000. Inset Ependymal cilia in transverse section possess a central doublet of microtubules surrounded by nine pairs, one of each pair having a characteristic hooklike appendage (arrows). X 100,000. 

For the lone pair orbitals the situation is somewhat more complicated. As mentioned before there are three trigonally equivalent lone pair orbitals at each end of the molecule which are arranged at 120° to each other, only one of which is shown on each atom. It can be observed that the lone pair orbital looks very much like a (s-p) hybrid on that particular atom, except for the little appendage which reaches over to the other atom. By connecting the po-...
