Extrinsic Muscle of Tongue

It is the only muscle that is capable of depressing the pupil when it is in a fully abducted position. Laterally by the thyroid cartilage and thyrohyoid membrane.

The inferior rectus muscle depresses adducts and helps extort the eye.

. This can lead to elevation of the eye as the superior rectus muscle remains. The motor component refers to the muscles of the tongue whereas the sensory component is associated with the structures called lingual papillae which contain taste receptors. The extrinsic muscles act to move the larynx superiorly and inferiorly.

The tongue is a muscular mass and although it is made up of several muscles all act in conjunction with each other to perform various movements. Inferiorly by the level of the inferior border of the cricoid cartilage. Inserts into the body of the hyoid bone and the entire length of the tongue.

Described as a pyramid the maxillary sinuses have a base on the lateral border of the nose with the apex. If the inferior rectus muscle is damaged weak or paralysed this can cause strabismus. Paired sinuses within the body of the maxilla.

The strength and mobility of the tongue are supported by its paired muscles which are grouped as either intrinsic or extrinsic. Medially by the aryepiglottic fold and arytenoid and cricoid cartilages. The structure is a depression bounded.

The tongue muscles can be divided into the intrinsic and extrinsic groups. Arises from the mandibular symphsis. Small arteries from the facial maxillary infraorbital and greater palatine arteries.

Allowing the whole of the larynx. Superior alveolar greater palatine and infraorbital nerves. They are comprised of the suprahyoid and infrahyoid groups and the stylopharyngeus a muscle of the pharynx.

Inferior fibres protrude the tongue middle fibres depress the tongue and superior fibres draw the tip back and down. Gross anatomy Relations andor boundaries. Broadly the intrinsic muscles can alter the shape of the tongue while the extrinsic muscles change the position of the tongue.

The extrinsic muscles are as follows. Tongue can depress or act in con-cert with other extrinsic muscles to retract tongue Hypoglossal Styloglossus 25 styloid process of temporal bone lateral inferior aspect of tongue retracts elevates tongue Hypoglossal Hyoglossus 26 body greater horn of hyoid bone inferolateral tongue depresses tongue draws its sides downward. The supra- and infrahyoid muscle groups attach to the hyoid boneThis in turn is bound to the larynx by strong ligaments.

Superiorly by the level of the hyoid bone.
