Which flexure is located in the midbrain region?

• A. Mesencephalic flexure
• B. Cervical flexure
• C. Pontine flexure
• D. Hypophysial flexure

Answer: (A)

Flexures are bends in the developing neural tube that allow the growing brain to fold into its final shape. The bend that sits in the midbrain region is the mesencephalic flexure, which forms within the midbrain (the mesencephalon). This location reflects its role at the boundary area between the forebrain and hindbrain as the brain curves during development. The other bends form in different regions: the cervical flexure at the junction between brainstem and spinal cord; the pontine flexure within the hindbrain between the metencephalon and the myelencephalon; and the hypophysial (infundibular) flexure in the forebrain near the developing pituitary.
