Final answer:
A radiologic test that examines the spinal cord is known as a Magnetic Resonance Imaging (MRI) scan, which is crucial for assessing sensory and motor functions associated with the spinal cord.
Step-by-step explanation:
A radiologic test that examines the spinal cord is called a Magnetic Resonance Imaging (MRI) scan. An MRI is a non-invasive imaging technology that produces three-dimensional detailed anatomical images without the use of damaging radiation. It is particularly useful for the visualization of soft tissues and organs, which makes it excellent for assessing the sensory and motor functions of the spinal cord. These exams are critical as the sensory functions are associated with the dorsal regions, and motor functions with the ventral regions of the spinal cord. Being able to accurately visualize the spinal cord is imperative for localizing damage and assessing conditions affecting it. The spinal cord, a thin, tubular bundle of nervous tissue, extends from the brainstem down the back to the pelvis and is responsible for connecting the brain with the peripheral nervous system. The spinal cord's health and functionality can be assessed through various neurological exams, of which the sensory and motor exams are major sections. These exams are important for diagnosing and managing diseases or trauma that affect the spinal cord and its nervous functions.
