What is the use of raphe?
Raphe (/ˈreɪfi/; from Greek ῥαφή, “seam”) 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 of continuous biological tissue.
What is the raphe on a male?
The penile and scrotal raphe is a subcutaneous fibrous plate extending from the penile frenulum, along the penile shaft and scrotum and toward the anus. In contrast, in the human perineum between the scrotum and anus, the urorectal septum is most likely to provide the perineal raphe as in mice.
What is the raphe line?
The line along the underside of a penis that runs from the tip of the penis to the anus is called the penile raphe (along the penis) or the scrotal raphe (along the scrotum). This raphe reminds us that before birth, male and female genitals start out looking the same.
What is an example of raphe?
Commonly, it is used with reference to the structure forming the fused ends of two flat muscle sheets. Examples include: anococcygeal raphe. bulbospongiosus raphe. lateral palpebral raphe.
Where is raphe located?
The raphe nucleus is considered to be part of the reticular formation and is located in the brainstem. It is responsible for the release of serotonin to other parts of the brain.
Do females have a raphe?
The perineal raphe is a visible line or ridge of tissue on the human body that extends from the anus through the perineum. It is found in both males and females, and arises from the fusion of the urogenital folds.
What’s perineal raphe?
What is the pharyngeal raphe?
The pharyngeal raphe is a midline tendinous seam where the constrictor muscles meet. When the superior constrictor muscle contracts, it constricts the upper portion of the pharynx. The middle constrictor muscle originates from the greater and lesser horn of the hyoid bone and stylohyoid ligament.
What does a raphe look like?
The raphe of the penis is a narrow, dark streak or ridge continuous posteriorly with the raphe of the scrotum and extending forward along the midline on the ventral surface of the penis.
Where is median fibrous raphe?
At present, the pharyngeal raphe is described in most anatomic textbooks and atlases as a more or less distinct and continuous band or line of connective tissue located in the median plane in the outer, circular part of the muscular layer of the pharynx.
What is Thyropharyngeus muscle?
The thyropharyngeus muscle originates from the thyroid cartilage and inserts into the median pharyngeal raphe. The cricopharyngeus muscle originates from the cricoid cartilage and blends into the esophageal muscle. When the inferior constrictors contract, they constrict the lower portion of the pharynx.
What does raphe mean in medical terms?
Medical Definition of raphe. : the seamlike union of the two lateral halves of a part or organ (as of the tongue, perineum, or scrotum) having externally a ridge or furrow and internally usually a fibrous connective tissue septum.
What is the meaning of perineal raphe?
perineal raphe a ridge along the median line of the perineum that runs forward from the anus; in the male, it is continuous with the raphe of scrotum. raphe of scrotum a ridge along the surface of the scrotum in the median line, continuous with the perineal raphe and the raphe of penis. raphe. rhaphe. n. pl.
Where does the raphe connect to the septum?
Internally, the raphe connects to a muscular partition, the septum, which serves to divide the scrotum into its two areas.
Where are the raphe nuclei located in the brain?
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.
