Explanation:

Question 148

The prefix "Myelo -" is a medical term. In medical terminology, "Myelo -" specifically refers to the spinal cord. For example, myelopathy means a disease of the spinal cord.

Cluster A personality disorders are characterized by odd or eccentric behavior. Paranoid personality disorder is in Cluster A. Avoidant personality disorder is in Cluster C (anxious - fearful). Borderline personality disorder is in Cluster B (dramatic, emotional, or erratic). Narcissistic personality disorder is also in Cluster B.

Angiography is the X - ray of blood vessels after injection of contrast medium. Lymphangiography is for lymphatic vessels. Arterio/gram is not the standard term for general blood vessel X - ray (angiography is more general for blood vessels, arteriography is for arteries specifically but less commonly used in this general context). Aorto/gram would be more specific to the aorta.

Answer:

spinal cord
