Fig. 6From: Detailed reconstruction of the nervous and muscular system of Lobatocerebridae with an evaluation of its annelid affinityEpidermal glands in Lobatocerebrum riegeri n. sp. as seen with CLSM and TEM. DAPI in cyan, acetylated α-tubulin in glow. b, d–e, g are maximum intensity projections of a subset of the original image stack on various locations of the body, c, f, h ultrastructural details of the epidermis. a Schematic cross section drawing of the epidermis with all three glandular cell types in their approximate abundance, b ciliated gland cell with closed circle of shortened cilia (inset with details of the tubular strands in the cellular membrane), c Sagittal section of a ciliated gland cell, d Tubular gland cell in the epidermis, e Tubular gland cell with long projection in the epidermis, f Sagittal section through the epidermis of the rostrum, presenting a tubular epidermal gland adjacent to a duct of the posterior frontal gland and the brain, g Kidney-shaped glands in the epidermis (inset with details of the glandular opening), h Cross section through a kidney-shaped gland.
