Skeletal muscle in tongue (iron haematoxillin)


Workbook tasks

Slide 19: Skeletal muscle (striated)


This is a section through the tip of the tongue stained to show the cross striations.

Identify microscopically:

  1. Longitudinal section of skeletal muscle
  2. The different bands in the longitudinal section that form the cross striations

  3. Nuclei of the skeletal muscle and connective tissue

Draw and annotate:

A skeletal muscle fibre. Indicate al the different components in detail.


  1. How many of the cross striation of skeletal muscle are visible under the light microscope?
  2. Can all the bands be seen?
  3. How does each band appear?
