Abstract:
Previous analyses of the scent gland secretions of snakes have focused on the nonvolatile components. Gas chromatography-mass spectrometry of secretions from North American garter snakes (Thamnophis butleri, T. couchi, T. elegans, T. melanogaster, andT. sirtalis) indicated the following seven major volatile components: acetic, propanoic, 2-methylpropanoic, butanoic, and 3-methylbutanoic acids, trimethylamine, and 2-piperidone. Five or more of these compounds were observed in secretions of select boid, colubrid, pythonid, and viperid snakes, suggesting that they are widespread scent gland products. 3-Methylbutanal also was detected in some snake species.

Exocrine Glands: Methods of Secretion
Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine...
Accessory Structures of the Skin: Sweat Glands
Sweat glands are classified as merocrine glands; that is, the secretions are excreted by exocytosis through a duct without affecting the cells of the gland. There...
Exocrine Glands: Types of Secretions
Serous glands produce watery secretions rich in digestive enzymes and proteins. The constituent cells of the serous gland have centrally located nuclei and eosinophilic secretory granules in the cytoplasm. The parotid gland is an example of a serous gland. It secretes saliva, which contains enzymes, such as lipases and...
