A cluster of sensory neuron cell bodies

Posterior root ganglion

2

Bones of the spine that enclose and protect the spinal cord

Vertebrae

3

In a reflex arc, the muscle or gland that responds with an action

Effector

4

A group of lumbar, sacral, and coccygeal nerves that branch off the lower end of the spinal cord

Reflex arc structure that passes the impulse from the receptor to the CNS

Sensory Neuron
