They differentiate into different cell types around the eleventh through the thirteenth postovulatory week. Between the ninth and eleventh week of gestation, many taste bud primordia develop. The first sign of development of taste bud on the lingual epithelium occurs at the 8th week of gestation. They are responsible for changing the shape of the tongue. On the other hand, the four paired intrinsic muscles which include superior longitudinal, inferior longitudinal, verticalis, and transverses muscle have their origin as well as insertion inside the tongue. They allow the tongue to move in all directions. The extrinsic muscles are four in number (genioglossus, palatoglossus, styloglossus, and hyoglossus) and originate from the structures adjacent to the tongue. The muscles of the tongue include extrinsic and intrinsic muscles.
They receive their innervations from the XII cranial nerve (hypoglossal nerve) except the palatoglossus muscle. The muscles of the tongue predominantly derive from the myoblasts which originate in the occipital somites.
This area of the tongue receives its innervations from the superior laryngeal nerve. The posterior-most part of the tongue develops from a third median swelling, arising from the fourth pharyngeal arch. The mucosa overlying this area of the tongue receives its sensory innervation from the IX cranial nerve (glossopharyngeal nerve). Meanwhile, from the mesoderm of the second, third, and fourth pharyngeal arches, another median swelling, known as hypobranchial eminence, begins to develop and form the posterior third of the tongue. Since the mucosa overlying this area of the tongue has its origin from the first pharyngeal arch it receives its sensory innervation from the mandibular branch of the V cranial nerve (trigeminal nerve). This merging leads to the formation of the anterior two-thirds of the tongue. As the lateral swellings increase in size, they eventually merge and overlap tuberculum impar. Gradually, two lateral lingual swellings start to grow in the 5th week from the same arch. The development begins with the growth of a medial swelling from the first pharyngeal arch, known as tuberculum impar. The first, second, third, and fourth pharyngeal arches contribute to the development of the various portions of the tongue. 26.The tongue begins to develop around the fourth week of intrauterine life. If you would like to to see how you can manage, whether with or without a bell-key, play piece no.
Fortunately, there is very little original recorder music, except some written since the key was invented by Carl Dolmetsch in the 1930s, that requires this note, and so even without a bell key fitted to your recorder you should be seldom troubled. If you are seated, and you do not have the advantage of a key, you may find it easier to cross your legs so that the leg is closer to the recorder bell. Dolmetsch have for many years produced a simple elegant solution - a bell key. On a large recorder closing the bell with one's knee can be both hazardous and unsightly. You will find a legion of alternatives offered by helpful teachers that might work once in a blue moon, that require that you slur rather than tongue, or that force you to accept an out-of-tune note in place of the secure, well tuned high F# you will be able to play when you use the fingering recommended above. High F# is one of the missing notes in the two and a half octave range for which there is no 'true' fingering unless one is prepared to close the end of the bell of your recorder (see the chart above).

How To Tongue The Note F# in the Third Octave Using the standard nomenclature, the fingering for third octave F sharp, or the enharmonic equivalent G flat, is written X 1 3 4 6a 6b with the bell closed, where X indicates a pinched thumb or vented thumbhole. Below that we give the standard fingering for this note, the fingering you would use under normal circumstances. Click on the play button in the Sibelius score to hear it.
The enharmonic equivalent is G flat which has the identical fingering. The twenty sixth note we learn, F# in the third octave on the treble (alto) recorder, lies above the third leger line above the treble clef.
