Some reflexes involve both the brain and the spinal cord while some only involve the spinal cord.
Reflexes don't always involve the spinal cord. Having to manage all the reflexes is hard, so some of them work without the spinal cord (eg. like the one in your knee.)
You have three neurons in reflex arc. Sensory neuron, connecting neuron and the motor neuron.

Superficial cord reflexes are the reflexes that happen when the body is exposed to pain. Superficial cord reflexes are centered in the spinal cord not the brain.
Introduction. Spinal cord reflexes are simple behaviors produced by central nervous system (CNS) pathways that lie entirely within the spinal cord. The sensory afferent fibers that evoke these reflexes enter the spinal cord and activate spinal motor neurons directly or through a chain of one or more spinal interneurons

Reflexes help to maintain homeostasis by permitting the body to make exceedingly rapid adjustments to homeostatic imbalances (The Spinal Cord and Spinal Nerves).
The spinal cord relays messages between the brain and body, making it possible to move and fell sensation.
