Chordata Data
Every animal in phylum chordata must have one of these.
What is spinal chord or notochord?
Only having a notochord during its larval stage, this subphylum resembles anything but an animal in its adult stage.
What is subphylum urochordata?
Known as the "FARM-B" subphylum, we will only study two of them during this module.
What is subphylum vertebrate/vertebrata?
All vertebrates enjoy lying on their backs and this type of circulatory system.
What is a closed circulatory system?
This type of fertilization is common in aquatic vertebrates.
What is external fertilization?
This subphylum contains those creatures that have a notochord through their larva stage but do not in their adult stage.
What is the Urochordata?
This urochord recycles its baby notochord for an adult tunic. Watch out! It likes to "squirt" when disturbed!
What is the sea squirt?
Unlike the invertebrates, who have an "exo", vertebrates may enjoy a little more movement with this.
What is the endoskeleton?
This vessel carries blood away from the heart in the vertebrate.
What are arteries?
What are: Oviparous, Ovoviviparous, and Viviparous?
This subphylum contains the animals that have notochords throughout their entire lives. *Hint: They have a head, too!
What is the cephalochordata?
Unlike the urochord, this subphylum likes to keep its notochord throughout its entire life.
What is subphylum cephalochord?
Skull, vertebrae, ribs, and sternum make up which part of the skeleton? (*sing*)
What is the axial skeleton?
Along with transferring oxygen, the red blood cell contains this protein that gives it the "red" in its name.
What is hemoglobin?
Guppies like to be "inside inside". They develop inside an egg that is hatched inside their mother. What is this type of development?
What is Ovoviviparous?
Unlike their invertebrate counterparts who prefer it ventrally, chordata must have this kind of nerve chord.
What is the dorsal nerve chord?
Shaped like a sword, this marine cephalochord's superhero name is "amphioxus".
What is the lancelet?
One way we fight cancer today is by bone marrow transplants. The unhealthy marrow in the middle of the bone is replaced with healthy marrow. What cells are most affected by this procedure?
What area blood cells? B/c bone marrow produces blood cells.
The vertebrates nervous system starts in the brain, which is segmented into these 5 "lobes". Generally, the right "lobes" control the left side of the body, and the left "lobes" control the right side of the body.
What are olfactory, optic, cerebrum, cerebellum, and medulla oblongata?
You, (name), used this form of development to grow into the fine young specimen you are today.
What is viviparous development?
These provide protection to that dorsal nerve chord.
What are vertebrae?
If a dead lancelet is found to have large particles of sand lodged in its pharyngeal slits, what was most likely not functioning?
Its oral cirri did not filter out the sand. Resulting in the poor lancelet's demise.
These are the 3 cells make up the bones in our bodies. (Rhymes with "mosteo".)
What are osteoblasts, osteoclasts, and osteocytes?
Your vital functions are all out of whack. Your nerves are not receiving accurate signals. What part of the your nervous system isn't doing its job?
What is the medulla oblongata?
Fish typically reproduce when the female lays her eggs and then the male fertilizes them. What kind of fertilization is this? What kind of development?
External fertilization and oviparous development.
