Afferent nerves carry signals away from the CSN to the target organ
- AAfferent nerves carry signals from the target organ to the CNS
10What is particular about the cranial nerve?
- AThey carry signals from the brain to the head
- BThey are only found in the midbrain of the brain stem
- CThey allow conscious control of brain function
11Where do spinal nerves carry signals to?
- AFrom the CNS to the rest of body
- BUp and down the spinal cord
- CFrom the body to the spine
12What is the role of the posterior rootlet?
- AThey carry sensory nerves to the CNS from the target organ

18A collection of anterior rami for a limb is called...?
- AA plexus
- BA spinal nerve
- CA spinoud
19What defines a general visceral fibre as opposed to a spinal nerve?
- AThey're from the autonomic system
- BThey form multiple ganglia before reaching the target organ
- CThey decussate multiple times (more than necessary)
20General visceral afferent fibres are..
