One again a program states that the tongue is a 'muscle'. I would like to ask you to check this out as it is constructed out of keratinised epithelial tissue. It has muscular qualities - true - however please check the histoligical make up.

I await your response to this as it may be that one of the 50% of things that have changed since university.

I have enclosed a link to some histological pictures for evidence

Where's a biologist when you need one? Welcome genuslearning :-)

At least not a muscle. The are both exterior and interior muscles.

The tongue is made up mainly of muscles, and covered with a layer of epithelial tissue (mucous membrane). It also includes other tissues. The mobility of the tongue proves that it's a muscular organ, since muscle is the only tissue type that can move.


From http://www.siumed.edu/~dking2/erg/oralcav.htm :

In addition to its clinical value as a readily-observed "window" onto a mucosal surface, the tongue also provides excellent opportunities for learning histology, with examples of all the basic tissue types appearing in a variety [of] forms.

In extended non-posting - or rarely posting - mode, for which I apologise.

The tongue is a muscular organ as anyone who has eaten slices of tongue can readily attest. It is not however one muscle but several.

Geniohyoid muscle is not part of what I would call the tongue but affects tongue function as it shifts the position of the hyoid which bears attachments for tongue muscles.

Quote:
The hypoglossal nerve [twelfth cranial nerve - Cel.] provides motor control of the extrinsic muscles of the tongue: genioglossus, hyoglossus, styloglossus, and the intrinsic muscles of the tongue. These represent all muscles of the tongue except the palatoglossus muscle. The hypoglossal nerve is of a general somatic efferent (GSE) type.
