The cervical flexure is located near the junction between which structures?

• A. Myelencephalon and spinal cord
• B. Forebrain and midbrain
• C. Metencephalon and diencephalon
• D. Telencephalon and mesencephalon

Answer: (A)

The cervical flexure marks the bend where the neural tube transitions from the hindbrain to the spinal cord. Specifically, it lies at the junction between the myelencephalon (the caudal part of the hindbrain) and the spinal cord. That boundary is what the cervical flexure describes, helping to position the brainstem relative to the spinal cord during development. The forebrain–midbrain boundary forms the cephalic flexure, and the bend between metencephalon and myelencephalon is the pontine flexure; the telencephalon–mesencephalon region isn’t defined by this particular flexure.
