What does 'tetraplegia' refer to in the context of spinal injuries?

Tetraplegia, also known as quadriplegia, refers to paralysis that affects all four limbs and typically arises from a cervical spinal cord injury. The term 'tetra' means four, indicating that both the upper and lower extremities are involved. This condition results from damage to the spinal cord at or above the cervical level, which disrupts the neural pathways responsible for movement and sensation in the limbs. Patients with tetraplegia may experience varying degrees of loss of motor function and sensation, depending on the severity and location of the injury. Understanding tetraplegia is crucial in the context of spinal injuries, as it guides medical treatment, rehabilitation strategies, and the overall management of affected individuals.
