- Define peripheral nervous system and list its components.
- Define nerve and describe the general structure of a nerve, giving functional
roles to layers.
- Distinguish between sensory, motor, and mixed spinal nerves.
- Distinguish between autonomic and somatic reflexes.
- Construct a general neural negative feedback loop.
- Demostrate your knowledge of somatic spinal nerves by constructing stretch,
tendon, flexor and crossed extensor somatic spinal reflexes. Use this neural negative feedback loop template. Describe the
stimuli for each reflex.
- Describe the segmented arrangement of peripheral nerves, skeletal muscles,
and skin dermatomes.
- Describe the gross and microscopic structure of the spinal cord (include
enlargements and plexus).
