5. Drawing (Dr)

The following guidelines should be used for drawing:

(a) The illustrations should be placed in a position on the page which will allow for neat
and clear labelling.

(b) If the illustration is included in the written material, it should be placed just before
this material and should be referred to in your answer.

(c) Illustrations should be done in pencil. The use of coloured pencils is not acceptable.

(d) The illustration should be large enough so that all structures can be clearly drawn.

(e) The illustration should be correctly proportioned and parts should be accurately
positioned.

(f) In order to get a smooth, unbroken line when drawing, lift the pencil from the paper
as infrequently as possible until the line is completely drawn. This method will help
to eliminate haphazard and sketchy lines.

(g) When a large number of small structures are present in a specimen, draw only a few
of them carefully, showing structural details.

(h) Write labels in pencil.

(i) Labels should be annotated (that is, accompanied by brief explanatory notes).

(j) Label lines should never cross each other and should be horizontal where possible.

(k) In illustrations where only a few structures are being labelled, all labels should be
written on the right of the drawing.

(l) Biological illustrations must have a full title and magnification. This is usually written
below the drawn item and underlined. The title tells the name of the structure or
organism and the view from which the illustration was made.

Note: A diagram should clearly indicate the following:
- tissues present;
- the position of the tissues in the organ relative to each other; and,
- the proportion of the tissues relative to each other in the section.
