Vertex (Crown of the Head) – Meaning and Usage in Medical English

👁 What Does “Vertex” Mean?

The vertex is the crown of the head: the highest point of the skull, on the midline at the top of the head. It lies above the ears and between the forehead and the back of the head.

The word is Latin for “highest point” or “summit”, from vertere, “to turn”. The plural is vertices. There is no common clinical adjective, so notes simply say at the vertex or over the vertex.

🔍 Clinical Usage

The vertex appears in neurology, obstetrics, dermatology and emergency notes:

• vertex presentation — the baby’s head, crown first, is the leading part in labor; the normal position for birth
• vertex headache — pain felt on the top of the head
• scalp lacerations at the vertex — common after falls or blows to the top of the head
• thinning at the vertex — a typical pattern of hair loss
• vertex on imaging — the top slice of a head CT or MRI

Common collocations include:

• cephalic vertex presentation
• pain radiating to the vertex
• laceration over the vertex
• vertex of the skull

Here’s a natural clinical example:

“Term pregnancy, singleton, vertex presentation, head engaged.”
→ Meaning: The pregnancy is full term with one baby, lying head first, and the head has moved down into the pelvis.

💡 OET Tip

With patients, say the top of your head or the crown. In writing, vertex is standard in obstetric and neurological notes. Don’t confuse vertex (top of the head) with vertigo (a spinning sensation); they share a Latin root but mean completely different things.
