Bundles of microtubules which compose rods that exhibit periodicity along their individual microtubules. Discoidal vesicles seem to be bound to the rod surfaces. The bundles of filaments penetrate int...

A view near the oral apparatus of Coleps and the attachment site of a microtubule filament bundle, fibrous interconnections, and a rod near a basal body that is out of the section plane in this TEM. D...

Longitudinal section of somatic cilia showing the axoneme, basal body, and attached fibrous and microtubular elements. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alco...

The endoplasmic reticulum exists in extensive sheets in the cytoplasm of Nassula immediately below the alveolar membranes. TEM taken on 3/14/69 by R. Allen with Philips 300 operating at 60kV. Neg. 16,...

Tangential section through the anterior half of the cytopharyngeal basket. Drawings and discussion of the basket can be found in a paper by Tucker, J. Cell Science 3: 493-514, 1968. TEM taken on 4/1/6...

Cytopharyngeal rods, composed of microtubular bundles, form the wall of the basket. Rod lamellae are attached to one side of each rod. TEM taken on 3/13/69 by R. Allen with Philips 300 operating at 60...

A high resolution of an oblique section of the Coleps contractile vacuole pore revealing the supporting microtubules and adjacent fibrous layer. Standard glutaraldehyde fixation followed by osmium tet...

Detail of spongiome of CV. The tubular network is continuous with the filling CV at numerous points. Some spongiome tubules my be decorated with V-ATPases. TEM taken on 3/27/69 by R. Allen with Philip...

An image of the contractile vacuole in diastole (filling phase). Decorated spongiome surrounds the CV. The macronucleus, micronucleus, cytopharynx, and basal bodies of perioral membranelle are include...

Figure 301 from Chapter 12 (Centrioles) of 'The Cell' by Don W. Fawcett M.D. Centrioles are usually positioned so that their long axes form a right angle. Their perpendicular orientation is maintained...
