Earthworm Model


Below are pictures of the earthworm model that will appear in the lab practical. In the pictures, parts are labeled. It is recommended that you first see the models before viewing these pictures, just so you will get an idea of what you are looking at.

brain and pharynx

esophagus

crop and gizzard

aortic arch

ventral aorta

intestine


seminal recepticles and ventral nerve and seminal vesicles

ventral nerve and nephridium

The following are parts and numbers of the Earthworm model that could be in the lab practical:

18-->Pharynx

Project Originally began by Dennis Anderson.
Molecular Models were assembled by DSCC Biology Professor Dr. Billy Williams.
Photography by Jonathon Mooney and Dennis Anderson.

The Lab Notes were produced by Dr. Billy Williams and Dr. Bill Redmond.

Labeled Models appearing in Biology 1110 &1120 were purchased from:

1. Bobbit Laboratories; Burlington, North Carolina

2. CENCO

3. Hubbard Scientific Co; Northbrook, Illinois

4. Nystrom Biological Model Co; Chicago, Illinois
