21 January 1992, 3 Jan 1996, 31 Dec '96, 23 Jan. '97, 7 Jan '98, 5 Jan 00, 31 Jan 01 | central canal, 400x |
Examine the cross sections of the spinal cord with the 4x objective first. Locate all major regions as listed below. At higher power, note cell structure of central canal, posterior and anterior gray horns, and funiculi. Then illustrate first at lowest power and label the following:
Slide 4: Spinal Cord cross section and longitudinal sections, H-Eosin (H 1537)
Make four illustrations:
