Levels Of The Spinal Cord And Its Main Functions MDCAT Quiz: The levels of the spinal cord and its main functions are an integral part of human physiology, providing the foundation for understanding neural coordination and reflex actions. It is a topic of paramount importance for MDCAT students to master, as it comes up in exam questions time and again. Prepare yourself better with an MDCAT Quiz on the anatomy and functionality of the spinal cord to ace this subject.
Structure and Functions of the Spinal Cord
The spinal cord has five levels: cervical, thoracic, lumbar, sacral, and coccygeal. Each level corresponds to specific nerve roots that control motor and sensory functions. The cervical region controls movements of the neck, arms, and diaphragm; the thoracic level controls the torso and autonomic functions. The lumbar and sacral levels control the legs and pelvic organs, while the coccygeal region contributes to the lower body. This information about divisions and their functions is very important to solve MDCAT questions related to spinal cord injuries and reflexes.
