Name the intrinsic muscles of the tongue (check all that apply).
Inferior longitudinal

Vertical
The intrinsic extrinsic( intrinsic, extrinsic ) muscles of the tongue change the shape of the tongue and produce rapid, delicate articulations while the extrinsic intrinsic( extrinsic, intrinsic ) muscles of the tongue move the tongue as a unit into the correct general location within the oral cavity.
The ❌ retracts, protrudes, and depresses the tongue. The ❌ pulls sides of tongue down. The ❌ draws the tongue back and up. The ❌ depresses the tongue. The ❌ elevates the tongue or depresses the soft palate.
The ❌ tongue muscle elevates, retracts, also deviates tip of tongue if only one side contracts. The ❌ tongue muscle pulls tongue tip down, retracts, also deviates tip of the tongue if only one side contracts. ❌ tongue muscle is the primary muscle for protruding the tongue, narrows the tongue. ❌ tongue muscle flattens tongue and pulls whole tongue into floor of the mouth.
Superior longitudinal muscles tongue tip. Inferior longitudinal muscles tongue tip. Left and right superior and inferior muscles tongue tip for left and right , respectively.
What muscles relax lateral margin?
Posterior genioglossus for protrusion
Superior longitudinal for tip elevation
Transverse intrinsic for pulling sides medially
All the above
Transverse intrinsic muscle the tongue.
For the tongue to create a deep central grove, the muscles involved are: ❌ for depression of the tongue body; ❌ for depression of central dorsum.
For a broad central groove of the tongue, the muscles involved: moderate genioglossus hyoglossus( moderate genioglossus, hyoglossus ) for depression of tongue body, vertical intrinsic transverse( vertical intrinsic, transverse ) for depression of dorsum, superior longitudinal inferior longitudinal( superior longitudinal, inferior longitudinal ) for elevation of margins.
To protrude the tongue, the muscles involved: ❌ for advancement of the tongue body, ❌ to narrow tongue, ❌ and ❌ to balance and point tongue.
To retract the tongue, muscles involved: ❌ for retraction of tongue into ORAL cavity, ❌ and ❌ for shortening of tongue, ❌ for retraction of tongue into PHARYNGEAL cavity.
What muscles are involved in elevating posterior tongue? Check all that apply.
Palatoglossus for elevation of sides of tongue
Transverse intrinsic to bunch tongue
Superior longitudinal for elevation of margins
What muscles contribute to depressing the tongue body? Check all that apply.
Genioglossus for depression of medial tongue
Hyoglossus for depression of sides of tongue
Chondroglossus for depression of sides of tongue
Inferior longitudinal muscles
What movements involve the genioglossus? Check all that apply.
Elevate & depress tongue tip
Deviate tongue tip
Relax lateral margin
Narrow tongue
Deep central groove
Broad central groove

The extrinsic and intrinsic muscles of the tongue are innervated by CN , the nerve. The palatoglossus is the only muscle that is innervated by a different nerve, which is CN , the nerve.
What are the attachments of the genioglossus?
Inner mandibular symphysis, tip and dorsum of tongue (and hyoid)
Greater cornu and lateral body of hyoid, sides of tongue
Styloid process of temporal bone, lateral surfaces of tongue merging w/ hyoglossus & inferior lateral margins, continuing to apex of tongue
Lesser cornu of hyoid, intrinsic muscles of the tongue medial to the point of insertion of hyoglossus
What are the attachments of the hyoglossus?
Styloid process of temporal bone, lateral surfaces of tongue merging w/ hyoglossus
What are the attachments of the styloglossus?
Styloid process of temporal bone, lateral surfaces of tongue merging w/ hyoglossus & inferior lateral margins, continuing to apex of
What are the attachments of the palatoglossus?
Soft palate (anterior faucial pillars)
