Protostomes (mouth first) Deuterostomes (mouth second) Cleavage type Spiral Radial Blastopore Mouth Anus becomes Representative Phyla Platyhelminthes, Arthropoda, Annelida, Mollusca, Nematoda, and smaller phyla Chordata, Echinodermata, and smaller phyla Example species Nematoda - Ascaris Sea star – Asterias Drawing Task 5: Describing positions in bilaterally symmetrical animals For a large portion of this course we will be examining bilaterally symmetrical animals from various phyla. To be able to locate and refer to specific regions of animal bodies, we will use terminology in your lab manual (pg. 523). Practice with your group using directional terms to refer to a particular part/portion of the body. You may use available specimens to practice. Make sure to use both radially and bilaterally symmetrical animals. The table below compares the terms used to describe animals with bilateral and radial symmetries.
Radially-Symmetrical and Bilaterally-Symmetrical Animals Bilateral Radial Direction Synonyms Direction Synonyms Anterior Rostral, Cranial, Cephalic Oral Apical Posterior Caudal Aboral Basal Dorsal — Peripheral — Ventral — Peripheral — Left (lateral) Sinister Peripheral — Right (lateral) Dexter Peripheral — Medial — Same — Proximal — Same — Distal — Same — Adapted from Wikipedia. Task 6: Body axes charades – Run by the TA To practice using the proper terminology to refer to different locations on the body, we will play a game of charades. Your TA will divide the whole class into two groups. Each group will be given a list of organs/ body parts. These lists will be different. Make sure not to share your list with members from the other group. Your group will choose a student from another group to describe one of the words on your list to his/her group. The student will have 2 minutes to describe the word, using only the words from the bilateral body axes (see table above). You cannot use words that describe the function of the organs. For example, if the organ to be described is the heart, then you cannot say that it pumps blood, but you can say that this organ is posterior to the head. If his/her group can guess the right organ /body part, his/her team gets a point but if they don’t guess correctly, then your team gets the point. Make sure to alternate the order of the teams guessing.
