Question

Three main levels of neural integration operate in the somatosensory system. Which level involves the spinal cord?

Answer 1

Answer:

The Secondary neural integration

Explanation:

The somatosensory system consists of the neurons that make sensing touch, temperature, and position in space possible. It is made up of primary, secondary, and tertiary neural integrations.

The secondary neuron acts as a relay and is located in either the spinal cord or the brainstem. This neuron’s increasing axons will cross, or decussate, to the opposite side of the spinal cord or brainstem and travel up the spinal cord to the brain, where most will end in either the thalamus or the cerebellum.

Answer 2

Answer: the circuit level

Explanation:

The three main levels of neural integration pathway includes:

1.) Receptor level.

2.) Circuit level.

3.) Perceptual level.

In processing at the circuit level, three chains of neurone conduct sensory impulses upward to the brain. The second order neurone (soma) resides in the dorsal horn of the spinal cord and transmit impulses to the thalamus or cerebellum. Therefore the correct level is the circuit level. I hope this helps.
