This is a dorsal root ganglion (DRG) from a chicken embryo (around stage of day 7) after incubation overnight in NGF growth medium stained with anti-neurofilament antibody. You can see the axons growing out of the ganglion.
This article deals with the nervous anatomical structure, the ganglion. For the medical term, see Ganglion cyst
There are two major groups of ganglia: spinal ganglia (also known as the dorsal root ganglia) and autonomic ganglia. The former contains the cell bodies of sensorynerves and the latter contains the cell bodies of autonomic nerves. In anatomy and neurology, the dorsal root ganglion (or spinal ganglion) is a nodule on a dorsal root that contains cell bodies of neurons in afferent spinal nerves. ... Template:Game Autonomic nervous system innervation, showing the sympathetic and parasympathetic (craniosacral) systems, in red and blue, respectively Autonomic ganglia are clusters of neuronal cell bodies and their dendrites and are essentially a junction between autonomic nerves originating from the central nervous system and autonomic nerves innervating their target organs... Senses are the physiological methods of perception. ... Nerves (yellow) Nerves redirects here. ... This article or section is in need of attention from an expert on the subject. ...
In the autonomic nervous system, fibers from the CNS to the ganglion are known as preganglionic fibers, while those from the ganglion to the effector organ are called postganglionic fibers. This article or section is in need of attention from an expert on the subject. ... A diagram showing the CNS: 1. ... In the autonomic nervous system, fibers from the CNS to the ganglion are known as preganglionic fibers. ... Acetylcholine Norepinephrine In the autonomic nervous system, fibers from the ganglion to the effector organ are called postganglionic fibers. ...
Categories: Neuroanatomy | Central nervous system | Peripheral nervous system | Autonomic nervous system | Medical terms The nervous system of an animal coordinates the activity of the muscles, monitors the organs, constructs and also stops input from the senses, and initiates actions. ... Drawing by Santiago RamÃ³n y Cajal of neurons in the pigeon cerebellum. ... A ganglion cell (or sometimes called a gangliocyte) is a type of neuron located in the retina that receives visual information from photoreceptors via various intermediate cells such as bipolar cells, amacrine cells, and horizontal cells. ... A ganglion cyst (also known as a bible bump) is a swelling that often appears on or around joints and tendons in the hand (or sometimes feet). ... This is a dorsal root ganglion (DRG) from a chicken embryo (around stage of day 7) after incubation overnight in NGF growth medium stained with anti-neurofilament antibody. ...
The ciliary ganglion is connected with the ophthalmic nerve; the sphenopalatine ganglion with the maxillary nerve; and the otic and submaxillary ganglia with the mandibular nerve.
In the sphenopalatine ganglion they form synapses with neurons whose postganglionic axons, vasodilator and secretory fibers, are distributed with the deep branches of the trigeminal to the mucous membrane of the nose, soft palate, tonsils, uvula, roof of the mouth, upper lip and gums, and to the upper part of the pharynx.
The branch of communication from the lingual to the forepart of the ganglion is by some regarded as a branch of distribution, through which filaments pass from the ganglion to the lingual nerve, and by it are conveyed to the sublingual gland and the tongue.
