The gnathosoma (from Greek γνάθος, gnáthos = "jaw" and σώμα, sóma = "body") is the part of the body of the Acari (mites and ticks) comprising the mouth and feeding parts. [1] These are the hypostome, the chelicerae and the pedipalps. [2] It is also called the capitulum [3] (however, this word also has other meanings).
Morphologically, an inflorescence is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis , as well as variations in the proportions, compressions, swellings, adnations , connations and reduction of main and ...
capitulum (plural capitula) may refer to: the Latin word for chapter. an index or list of chapters at the head of a gospel manuscript; a short reading in the Liturgy of the Hours. derived from which, it is the Latin for the assembly known as a chapter; a typographic symbol (⸿), to mark chapters or paragraphs, now evolved into the pilcrow
Illustration of the gnathosoma of an acarine, showing the subcapitulum. The subcapitulum (from Latin sub, "under", and capitulum, "small head"), also known as infracapitulum, [1] [2] hypognathum [3] or hipognatum, refers to the ventral part of the gnathosoma (the part of the body comprising the mouth and feeding parts) [4] or the fusion of the palpal (of the pedipalps, the second pair of ...
The inflorescence is a capitulum, 7 to 15 cm (3 to 6 in) in diameter, formed by a prominent domed central protuberance consisting of multiple small yellow florets. These are surrounded by a ring of pink or purple ligulate florets.
For example, the leaves of pine, oak, and cabbage all look very different, but share certain basic structures and arrangement of parts. The homology of leaves is an easy conclusion to make. The plant morphologist goes further, and discovers that the spines of cactus also share the same basic structure and development as leaves in other plants ...
The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. [1] Examples of pseudanthia include flower heads, composite flowers, [2]: 514 or capitula, which are special types of inflorescences [3] in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped ...
Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
