Comparing Divisions Of The Central Nervous System ( Brain + Spinal Cord)

Question 1

Both receive and process information from the PNS

Answer 1

sensory info from the somatic is sent to the spinal cord first, where some of it is processed, allowing reflex actions. After this, it is sent to the brain, where it is processed further.

Question 2

Both coordinate actions within the body

Answer 2

The spinal cord coordinates actions in the body for reflex actions whilst the brain coordinates all other actions of the body

Question 3

Brain is conscious but spinal cord isn’t

Answer 3

Only the brain is the centre of conscious experiences. The spinal cord coordinates reflex actions. These happen unconsciously.

Question 4

Unlike the spinal cord, the brain is the final destination for sensory information

Answer 4

sensory info is sent to the spinal cord from the PNS, but from there it is then sent to the brain. This is because the brain is the main point of the nervous system where information is processed
