Question

Spinal roots and rami are similar in that they both contain sensory and motor fibers?

1) True
2) False

Answer 1

Spinal roots and rami both contain sensory and motor fibers.

a) True

Step-by-step explanation:

Spinal roots and rami are indeed similar in that they both contain sensory and motor fibers.

Spinal nerves transmit sensory and motor information between the spinal cord and the rest of the body. Each of the 31 spinal nerves (in humans) contains both sensory and motor axons. The sensory neuron cell bodies are grouped in structures called dorsal root ganglia. Motor neurons have cell bodies in the ventral gray matter of the spinal cord that project to muscle through the ventral root.
