Posterior Meningeal Artery

The Posterior Meningeal Artery (PMA) (/pɒˈstɪəriər mɛnɪnˈdʒiːəl ˈɑːrtəri/), is a small artery that supplies blood to the meninges and parts of the inner ear.

Etymology

The term "Posterior Meningeal Artery" is derived from the Latin words 'posterior' meaning 'behind', 'meninx' meaning 'membrane', and 'arteria' meaning 'windpipe, artery'.

Anatomy

The Posterior Meningeal Artery typically arises from the ascending pharyngeal artery, but can also originate from the occipital artery or the vertebral artery. It ascends to the jugular foramen, passing through to reach the posterior cranial fossa where it supplies the meninges and parts of the inner ear.
