Internode may refer to: Internode (botany), a portion of a plant stem between nodes; Internode (ISP), an Internet service provider in Australia;
An internodal segment (or internode) is the portion of a nerve fiber between two Nodes of Ranvier. The neurolemma or primitive sheath is not interrupted at the nodes, ...
A stalk-like structure, internode located between the calyx and the other parts of the flower. anticlinal Pointing up, away from, or perpendicular to a surface. Contrast periclinal. antrorse Directed forward or upward, e.g. of hairs on a stem. Contrast retrorse. apetalous Lacking petal s. apex. pl. apices. The tip; the point furthest from the ...
Internode: An interval between two successive nodes. It possesses the ability to elongate, either from its base or from its extremity depending on the species. Node: A point of attachment of a leaf or a twig on the stem in seed plants. A node is a very small growth zone.
When a longitudinal section is made through a myelinating Schwann cell at the node, three distinctive segments are represented: the stereotypic internode, the paranodal region, and the node itself. In the internodal region, the Schwann cell has an outer collar of cytoplasm, a compact myelin sheath, and inner collar of cytoplasm, and the axolemma.
The discontinuous structure of the myelin sheath results in the action potential "jumping" from one node of Ranvier over a long (c. 0.1 mm – >1 mm, or 100–1000 micron) myelinated stretch of the axon called the internodal segment or "internode", before "recharging" at the next node of Ranvier.
In the purest sense, that of a smooth stem without leaves or branches, a scape is a single internode. It might comprise an entire peduncle with just one flower (e.g. Tulipa) or just the basal internode of a peduncle. This is in contrast to the typical compound peduncle, which morphologically speaking is derived from a branch, or from an entire ...
2. Shows an average plant with a moderate amount of gibberellins, and an average internode length. 3. Shows a plant with a large amount of gibberellins and so has a much longer internode length, because gibberellins promote cell division in the stem. Gibberellins are involved in the natural process of breaking dormancy and other aspects of ...
