Abstract

The fine structure of silkmoth sense hair surfaces has been investigated by freeze etching with Pt/C rotary shadowing. To do this, the hydrophobic layer in the cuticle was removed using 20-25% methanol or ethanol. Freeze-etch patterns of sense hair surfaces, as well as the pore structure and pore distribution, are shown. The hair surface has a nonhelical 'band' structure, in which every 'band' lies at an oblique angle with respect to the axis of the hair. Each 'band' is separated fromits neighbour by a 30-nm step. The average density of pores is 11.3 +/- 2.4 pores mu m(-2). Freeze-etch patterns of the single and multiplepore tubules are shown. Evidence for direct contact between the pore tubule and dendrite membrane of an olfactory receptor neuron is presented.
