Afferent axon - Study guides, Class notes & Summaries

Afferent - Towards (towards the spinal cord) Efferent - Away From (away from the spinal cord) Which nerves are incapable of regeneration? - Neurons in the Central Nervous System (CNS) do not divide and injury causes permanent loss. Which injury to nerves has better outcomes? Crushed or Severed/Cut - Crushed nerves recover better How do peripheral nerves repair themselves? - Axonal Reaction Name 8 local changes that occur when an axon is severed - 1. Cut end retracts and the axolemma cove...

Which is a correctly ordered pathway for afferent information where immediately adjacent is NOT required? [For example, ABDG is correctly ordered alphabetically even though NOT immediately adjacent like ABCD] A) Afferent neuron - brainstem - thalamus B) Spinal cord - cerebellum - cerebral cortex C) Afferent neuron - spinal cord - cerebellar cortex D) Spinal cord - thalamus - diencephalon - ️️A) Afferent neuron - brainstem - thalamus Although he asked for a "regular" soda, Phys ...
