extrinsic muscle

The four extrinsic muscles act to change the position of the tongue, and are anchored to bone.

The extrinsic muscle groups are the long flexors and extensors.

There are three pairs of extrinsic muscles of the larynx.

It is a type of vergence eye movement and is done by extrinsic muscles.

Palatoglossus The extrinsic muscles originate from bone and extend to the tongue.

Diplopia, commonly referred to as double vision, can result if one of the eye's extrinsic muscles are weaker than the other.

The intrinsic muscles lie entirely within the tongue, while the extrinsic muscles attach the tongue to other structures.

The four paired extrinsic muscles protrude, retract, depress, and elevate the tongue:

The extrinsic muscles reposition the tongue, while the intrinsic muscles alter the shape of the tongue for talking and swallowing.

In human anatomy, the abductor pollicis longus (APL) is one of the extrinsic muscles of the hand.

The auricular muscles (or extrinsic muscles) are the three muscles surrounding the auricula or outer ear:

An extrinsic muscle, the flexor pollicis brevis, attaches to the plate, such that contraction of the muscle alters overall disc shape, creating suction.

In this group careful attention should be paid to anomalous tendons coming from the forearm (extrinsic muscles, like an aberrant long thumb flexor - flexor pollicis longus).

The extrinsic muscles are the ones way at the back of the tongue which anchor the tongue to the skeleton (yup, the tongue bone attaches to the chest bone).

The APL insertion on the trapezium and the APB origin on the same bone is the only connection between the thumb's intrinsic and extrinsic muscles.

"If you look at the muscles, both the intrinsic hand muscles and the extrinsic muscles, all are arranged around an axis through the middle finger, so it is in position to exert the greatest amount of force," he said.

Parts of the body which play an important role in performing this asana are: both the intrinsic and extrinsic muscles of the feet, the quadriceps, the iliopsoas muscles, the piriformis, abdominal wall, and the diaphragm.

Tumor invades through the thyroid cartilage and/or invades tissues beyond the larynx (e.g., trachea, soft tissues of neck including deep extrinsic muscle of the tongue, strap muscles, thyroid, or esophagus).

The extrinsic muscles include the biceps, triceps, and deltoid muscles and attach to the coracoid process and supraglenoid tubercle of the scapula, infraglenoid tubercle of the scapula, and spine of the scapula.

The intrinsic muscles of the forearm act on the forearm, meaning, across the elbow joint and the proximal and distal radioulnar joints (resulting in pronation or supination, whereas the extrinsic muscles act upon the hand and wrist.

The muscles acting on the foot can be classified into extrinsic muscles, those originating on the anterior or posterior aspect of the lower leg, and intrinsic muscles, originating on the dorsal (top) or plantar (base) aspects of the foot.

When this becomes severe to the point of stupor or coma (defined as a score on the Glasgow Coma Scale of less than 8), dynamic collapse of the extrinsic muscles of the airway can obstruct the airway, impeding the free flow of air into the lungs.

All intrinsic and extrinsic muscles of the tongue are supplied by the hypoglossal nerve (CN XII), except for one of the extrinsic muscles, palatoglossus, which is innervated by the Vagus nerve CN X of the pharyngeal plexus.
