1. NUTS AND BOLTS to get started

2. Location Terms Superior-inferior Medial- lateral Dorsal-ventral
Rostral-Caudal…Anterior/Posterior

3. Planes of orientation

4. Dorsal Fin

5. The basic unit of the nervous system

6. White matter and gray matter

7. Staining for myelin in the brain coronal section

8. Staining for cell bodies in the brain-coronal section

9. Let’s begin with the PNS

10. The vertebral column

13. Each segment is similar

15. Dorsal = sensory Ventral = motor

16. Each vertebra houses a spinal cord segment

17. And the column collectively gives rise to 31 peripheral nerve pairs

18. Each nerve pair contains thousands of incoming and outgoing axons

23. motor output to skeletal muscles

24. And somatosensory input

27. The other subdivision of the PNS-the ANS

28. The sympathetic chain

29. Sympathetic activation may be magnified by adrenal gland
