Perineal raphe - Wikipedia
The perineal raphe is a visible line or ridge of tissue on the body that extends from the anus through the perineum to the scrotum (male) or the vulva (female).
Raphe - Wikipedia
Raphe (/ ˈ r eɪ f i / RAY-fee; from Ancient Greek: ῥαφή, romanized: rhaphḗ, lit. 'seam'; [1] pl.: raphae or raphes) has several different meanings in science. In botany and planktology, it is commonly used when describing a seam or ridge on diatoms or seeds. In animal anatomy, it is used to describe a ridged union [2] of continuous ...
Raphe nuclei - Wikipedia
The raphe nuclei (Greek: ῥαφή, "seam") [1] are a moderate-size cluster of nuclei found in the brain stem. They have 5-HT1 receptors which are coupled with Gi/Go-protein -inhibiting adenyl cyclase. They function as autoreceptors in the brain and decrease the release of serotonin.
Neuroanatomy, Nucleus Raphe - StatPearls - NCBI Bookshelf
2023年5月1日 · The raphe nuclei are positioned midline in the brainstem throughout the midbrain, pons, and medulla. These nuclei contain primarily serotonergic neurons, which release serotonin (5-hydroxytryptamine) with autocrine and paracrine effects, as well as synaptic connections. Serotonin generation comes from L-tryptophan via a two-step process catalyzed by tryptophan …
Raphe Definition & Meaning - Merriam-Webster
The meaning of RAPHE is the seamlike union of the two lateral halves of a part or organ (such as the tongue) having externally a ridge or furrow.

Raphe Nucleus - an overview | ScienceDirect Topics
A Raphe Nucleus is defined as a group of diverse cell clusters located in the brainstem that house the majority of serotonin-producing neurons in the central nervous system.
Know Your Brain: Raphe Nuclei - @neurochallenged
What are the raphe nuclei and what do they do? The raphe nuclei are the primary location in the brain for the production of the neurotransmitter serotonin, and the serotonin synthesized in the raphe nuclei is then sent throughout the entire central nervous system.
The diverse role of the raphe 5-HTergic systems in epilepsy
2022年5月25日 · The raphe nuclei comprise nearly all of 5-hydroxytryptaminergic (5-HTergic) neurons in the brain and are widely acknowledged to participate in the modulation of neural excitability.
Anatomically Defined and Functionally Distinct Dorsal Raphe Serotonin ...
The dorsal raphe (DR) constitutes a major serotonergic input to the forebrain and modulates diverse functions and brain states, including mood, anxiety, and sensory and motor functions. Most functional studies to date have treated DR serotonin neurons as a single population.
