Homework #4 -- External Cross-Sections
Due by Monday, September 10, 2012 or at
the beginning of class on Tuesday, September 11, 2012.
Draw three cross-sections of the grasshopper shown in the drawing below: one through the mid-point of its head, one through the mid-point of its thorax, and one through the mid-point of its abdomen. Label all major sclerites (e.g. gena, notum, sternum, etc.) and other external structures (e.g. eyes, mouthparts, etc.). Make sure you know the difference between a cross-section (transverse section) and a sagittal section (longitudinal section). Your drawing should be bilaterally symmetrical and should include only those structures that intersect the cross-sectional plane. Save copies of your drawings -- you will add internal features later.
Submit your answers in class (preferably) or e-mail to firstname.lastname@example.org
If you choose to submit via e-mail, save your drawings in PDF format.
