Levator Veli Palatini

Soft Palate · Head & Neck

Levator Veli Palatini belongs to the Soft Palate group of the Head & Neck. It arises from Petrous part of the temporal bone and cartilage of the auditory (Eustachian) tube and attaches to Palatine aponeurosis. Functionally, it elevates the soft palate during swallowing and yawning. It is innervated by the Vagus nerve (CN X) via the pharyngeal plexus.

Origin, Insertion, Action & Nerve

Origin

Petrous part of the temporal bone and cartilage of the auditory (Eustachian) tube

Insertion

Palatine aponeurosis

Action

Elevates the soft palate during swallowing and yawning

Nerve

Vagus nerve (CN X) via the pharyngeal plexus

Attachments explained

The Levator Veli Palatini is defined first by where it attaches. Its origin is the more fixed anchor, usually the proximal or more stable end that stays put during contraction, while its insertion is the more mobile point that is pulled toward the origin when the muscle shortens.

Origin

Insertion

Palatine aponeurosis

Action & function

When the Levator Veli Palatini contracts, it produces the following movement: Elevates the soft palate during swallowing and yawning.

As part of the Soft Palate group of the Head & Neck, it works alongside neighbouring muscles to generate smooth, coordinated movement and to stabilise the structures it acts on.

Nerve supply & clinical relevance

The Levator Veli Palatini receives its nerve supply from the Vagus nerve (CN X) via the pharyngeal plexus.

Because a muscle can only contract when its nerve is intact, injury to the Vagus nerve can weaken or paralyse the Levator Veli Palatini, impairing the movements it normally produces (elevates the soft palate during swallowing and yawning). This is why knowing the innervation is central to localising nerve lesions in clinical practice.

How to study the Levator Veli Palatini (the OIANS method)

OIANS stands for Origin, Insertion, Action and Nerve, the four facts that uniquely define every skeletal muscle. To learn the Levator Veli Palatini, work through them in order: picture its origin, trace the muscle to its insertion, reason out the action that shortening between those two points must create, then add the nerve that drives it.

Most students remember the Levator Veli Palatini fastest by linking its action back to its attachments rather than memorising each fact in isolation. Once the origin and insertion make sense, the action usually follows logically.
