Superior Labial Nerve

The Superior Labial Nerve is a branch of the Facial Nerve that supplies the upper lip. It is also known as the Infraorbital Nerve.

Etymology[edit | edit source]

The term "Superior Labial Nerve" is derived from the Latin words 'superior' meaning 'higher', 'labial' meaning 'pertaining to the lip', and 'nervus' meaning 'nerve'.

Anatomy[edit | edit source]

The Superior Labial Nerve is a branch of the Facial Nerve, which is the seventh cranial nerve. It provides sensory innervation to the skin and mucous membrane of the upper lip. It also supplies the Nasal Septum and the anterior part of the Hard Palate.

Function[edit | edit source]

The primary function of the Superior Labial Nerve is to provide sensory innervation to the upper lip. This includes the sensation of touch, temperature, and pain. It also plays a role in the motor function of the muscles around the mouth, aiding in facial expressions and speech.

Clinical Significance[edit | edit source]

Damage to the Superior Labial Nerve can result in numbness or loss of sensation in the upper lip. This can be caused by trauma, surgery, or certain medical conditions such as Bell's Palsy or Stroke. Treatment typically involves addressing the underlying cause and may include medication, physical therapy, or surgery.
