  2. Ganglion - Wikipedia

    en.wikipedia.org/wiki/Ganglion

    Cranial nerve ganglia contain the cell bodies of cranial nerve neurons. Autonomic ganglia contain the cell bodies of autonomic nerves. In the autonomic nervous system, fibers from the central nervous system to the ganglia are known as preganglionic fibers, while those from the ganglia to the effector organ are called postganglionic fibers.

  3. Myenteric plexus - Wikipedia

    en.wikipedia.org/wiki/Myenteric_plexus

    The fibers are carried by both the anterior and posterior vagal nerves. The myenteric plexus is the major nerve supply to the gastrointestinal tract and controls GI tract motility. [1] According to preclinical studies, 30% of myenteric plexus' neurons are enteric sensory neurons, thus Auerbach's plexus has also a sensory component. [2] [3]

  4. Plant anatomy - Wikipedia

    en.wikipedia.org/wiki/Plant_anatomy

    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.

    They are sometimes found in connection with the ganglia of other sympathetic plexuses. None have been found with the sympathetic ganglia associated with the branches of the trigeminal nerve . The largest chromaffin paraganglion is the organ of Zuckerkandl , it is probably the largest source of circulating catecholamines in the fetus and young ...

  6. Plexus - Wikipedia

    en.wikipedia.org/wiki/Plexus

    In neuroanatomy, a plexus (from the Latin term for "braid") is a branching network of vessels or nerves. The vessels may be blood vessels (veins, capillaries) or lymphatic vessels. The nerves are typically axons outside the central nervous system. The standard plural form in English is plexuses. [1] [2] [3] Alternatively, the Latin plural ...

  7. Nerve plexus - Wikipedia

    en.wikipedia.org/wiki/Nerve_plexus

    A nerve plexus is composed of afferent and efferent fibers that arise from the merging of the anterior rami of spinal nerves and blood vessels. There are five spinal nerve plexuses, except in the thoracic region, as well as other forms of autonomic plexuses, many of which are a part of the enteric nervous system. The nerves that arise from the ...

  8. The Nervous Mechanism of Plants - Wikipedia

    en.wikipedia.org/.../The_Nervous_Mechanism_of_Plants

    “The Nervous Mechanism of Plants”, published in 1926, is a botany book by Sir Jagadish Chandra Bose which summarises his most recent findings in the area of plant physiology. Bose had previously investigated this topic in books such as Plant response as a means of physiological investigation from 1906, or The physiology of photosynthesis ...

  9. Plant morphology - Wikipedia

    en.wikipedia.org/wiki/Plant_morphology

    The detailed study of reproductive structures in plants led to the discovery of the alternation of generations, found in all plants and most algae, by the German botanist Wilhelm Hofmeister. This discovery is one of the most important made in all of plant morphology, since it provides a common basis for understanding the life cycle of all plants.
