The term "ganglion" refers to the peripheral nervous system. [ 1 ] However, in the brain (part of the central nervous system ), the basal ganglia are a group of nuclei interconnected with the cerebral cortex , thalamus , and brainstem , associated with a variety of functions: motor control, cognition, emotions, and learning.
Retinal ganglion cell (RGC) found in the ganglion cell layer of the retina [1] Cells that reside in the adrenal medulla, where they are involved in the sympathetic nervous system's release of epinephrine and norepinephrine into the blood stream; Cells of the sympathetic ganglia; Cells of the parasympathetic ganglia; Cells of the spiral ganglia [2]
An autonomic ganglion is a cluster of nerve cell bodies (a ganglion) in the autonomic nervous system. The two types are the sympathetic ganglion and the parasympathetic ganglion . [ 1 ] [ 2 ]
The sympathetic ganglia, or paravertebral ganglia, are autonomic ganglia of the sympathetic nervous system. Ganglia are 20,000 to 30,000 afferent and efferent nerve cell bodies that run along on either side of the spinal cord. Afferent nerve cell bodies bring information from the body to the brain and spinal cord, while efferent nerve cell ...
The cell bodies of sensory neurons known as first-order neurons are located in the dorsal root ganglia. [2] The axons of dorsal root ganglion neurons are known as afferents. In the peripheral nervous system, afferents refer to the axons that relay sensory information into the central nervous system (i.e. the brain and the spinal cord).
The submandibular ganglion (or submaxillary ganglion in older texts) is part of the human autonomic nervous system. It is one of four parasympathetic ganglia of the head and neck. (The others are the otic ganglion , pterygopalatine ganglion , and ciliary ganglion ).
The segmental ganglia (singular: s. ganglion) are ganglia of the annelid and arthropod central nervous system that lie in the segmented ventral nerve cord. The ventral nerve cord itself is a chain of metamerism ganglia, some compressed.
The indications for ganglion impar blockade are based on the anatomical location of pain and include various conditions such as perineal pain (with or without malignancy), rectal/anal pain (proctitis), distal urethral pain, vulvodynia, scrotal pain, female pelvic/vaginal pain (distal 1/3), sympathetically-maintained pain (e.g., Complex Regional ...
