To review the characteristics of the meninges and the spinal cord and to observe the major features of these structures

LEARNING OBJECTIVES:
1. Name the layers of the meninges and describe the structure of each
2. Identify the major parts of the spinal cord

PROCEDURE A: MENINGES
1. Review the Structure of Meninges in Cpt 8 238-240

2. Complete Part A in your Lab Notebook

PROCEDURE B: STRUCTURE OF THE SPINAL CORD

3. Review the Structure of the Spinal Cord in Cpt 8 240-243

4. Print out figures 24.1 and 24.2, paste them into your Lab NoteBook and label them

5. Complete Part B in your Lab NoteBook

6. Obtain a slide of a spinal cord in cross section (see image #1 on the HistoWeb site). Draw it in your NoteBook and label the following parts: posterior median sulcus, anterior median fissure, central canal, gray matter (gray commissure, posterior horn, anterior horn, lateral horns), White matter (posterior funiculus, anterior funiculus, lateral funiculus), dorsal root of spinal nerve, dorsal root ganglia, ventral root of spinal nerve

7. Complete Part B in your Lab NoteBook

8. Print out figures 24.3, paste it into your Lab NoteBook and label it
