Pronunciation: [ɹˈaf] (IPA) 
The word "raphe" is spelled with the letters "r," "a," "p," "h," and "e." In IPA phonetic transcription, it is pronounced as /ɹeɪf/. The "r" is an approximant sound, while the "a" produces a long "ay" sound. The "p" is a voiceless bilabial stop, followed by the voiceless glottal fricative "h." The final "e" produces a soft /ɛ/ sound. The spelling of "raphe" accurately represents its pronunciation in English.
Raphe refers to a linear anatomical structure found in various tissues and organs of the human body. Derived from the Greek word "rhaphē" meaning "seam" or "suture," raphe commonly describes a visible union or joining of two symmetrical or bilateral structures. It predominantly refers to a fibrous ridge or groove that serves as a point of attachment or connection.
In human anatomy, raphe is often encountered in several locations. For instance, the term is frequently used to describe the median raphe, a ridge that divides the human brain into two symmetrical cerebral hemispheres. This midline structure extends from the frontal to the occipital lobe, demarcating the separation between the right and left cerebral hemispheres.
In other contexts, raphe may refer to the linea alba, a fibrous structure in the abdomen. This midline band runs vertically between the xiphoid process of the sternum down to the pubic symphysis, offering stability and connection for various abdominal muscles.
Moreover, raphe is also observed in tissues such as the tongue, where it denotes the seam-like grooves joining muscle fibers, or in the scrotum, delineating the union of the two halves of the external male genitalia.
Overall, raphe serves as a descriptive term highlighting the connection or midline structure present in various tissues and organs, often demarcating bilateral symmetry.
The line of union of two contiguous and similar structures.

The word "raphe" is derived from the Ancient Greek term "rhaphe" (ῥαφή), meaning "seam" or "suture". In medicine, it refers to anatomical structures that appear as a ridge or line, resembling a seam. This term was adopted into Latin as "rapha", and eventually made its way into English as "raphe".
