Nervio mandibular: características anatómicas y funciones

The mandibular nerve transmits sensations from the lower jaw and teeth, and controls movement of the chewing muscles.

The inferior alveolar nerve branches off from the mandibular nerve.

The mandibular nerve innervates structures including the lower jaw, teeth, and some facial skin.

The mandibular nerve exits the skull through the foramen ovale.

The mandibular nerve controls the muscles involved in chewing.

The mandibular nerve connects to the trigeminal ganglion and other nerves in the face and jaw region.

The lingual vein drains blood from the tongue.

The middle thyroid vein drains into the brachiocephalic vein.

The superior thyroid vein originates from the thyroid gland and larynx.

The lingual vein is related to the sternocleidomastoid muscle.

The internal maxillary vein (or pterygoid plexus) drains into the internal jugular vein.

The internal jugular vein doesn't have any major side branches.

The external jugular vein runs near the temporal muscle and auriculotemporal nerve.

The external jugular vein drains into the internal jugular vein.

The superior thyroid vein carries deoxygenated blood back to the heart.

The retromandibular vein joins with the facial vein.

The internal maxillary vein transports deoxygenated blood back to the heart.

The pterygopalatine artery supplies blood to the sinuses in the face.

The descending pharyngeal artery is a side branch of the pterygopalatine artery.

The sphenopalatine artery originates from the maxillary artery.

The sphenopalatine artery supplies blood to the nasal lining and turbinates.

The descending pharyngeal artery is a side branch of the sphenopalatine artery.

In its terminal branches, the pterygopalatine artery connects with the facial artery.

Submandibular lymph nodes filter lymph to remove pathogens and abnormal cells.

Submental lymph nodes drain the submental region and surrounding areas of the neck and lower jaw.

Lymph nodes located below the chin belong to the submental group.

Submandibular lymph nodes drain the submandibular gland and floor of the mouth.

Pericervical lymph nodes process lymph to remove pathogens and abnormal cells.

The parotid region is not directly associated with submandibular lymph nodes.
