An abnormal patellar reflex indicates damage of the T10 - T12 spinal segments.

Patellar Reflex

A reflex action that causes the lower leg to kick forward when the patellar tendon just below the kneecap is tapped; a measure of the function of the nervous system.

Spinal Segments

Sections of the spinal cord that correspond to the vertebrae, from which spinal nerves emerge to innervate specific areas of the body.

Understand the principles and significance of reflex actions in human physiology, encompassing the stretch reflex and reciprocal innervation.
Acquire knowledge about the configuration and tasks of the spinal cord and its adjoining components.

Final Answer :

False

An abnormal patellar reflex indicates potential damage or issues with the L2-L4 spinal segments, not T10-T12. The patellar reflex tests the function of the femoral nerve, which originates from the lumbar spinal nerves L2-L4.
