Chapter 14 Flashcards
(35 cards)
amphibian:
A vertebrate animal that lives both on land and in water, typically having a larval stage in water and an adult stage on land.
anterior:
The front or head end of an animal.
bilateral symmetry:
Body symmetry in which an animal can be divided into two mirror-image halves along a single plane.
cephalization:
The concentration of sensory organs and nervous tissue at the anterior end of an animal.
cnido
Relating to stinging cells.
-cyte, cnidocyte:
A stinging cell characteristic of cnidarians (e.g., jellyfish, corals)
dorsal
The back or upper side of an animal.
ectoderm
The outermost germ layer in animal embryos, giving rise to the epidermis and nervous system.
endoderm
The innermost germ layer in animal embryos, giving rise to the digestive tract and associated organs.
incurrent & excurrent siphon of bivalves & cephalopods:
Tubes used for drawing in and expelling water, respectively, for feeding, respiration, and locomotion.
FARMB:
An acronym representing the major classes of vertebrates: Fish, Amphibians, Reptiles, Mammals, Birds.
flatworms
Invertebrates with flattened bodies and no body cavity.
gastro-:
Relating to the stomach or digestive system.
dermis:
The layer of skin beneath the epidermis.
invertebrates
Animals without a backbone.
mammals:
Warm-blooded vertebrates with hair and mammary glands
mesoderm:
The middle germ layer in animal embryos, giving rise to muscles, bones, and circulatory system.
no muscle, no nervous tissue:
Refers to sponges, the only animal phylum lacking true tissues.
osmoregulation:
The control of water and solute balance in an organism.
radial symmetry:
Body symmetry in which an animal can be divided into equal halves along any plane passing through the central axis.
reptiles
Cold-blooded vertebrates with scales and lungs.
sponges:
Simple aquatic invertebrates with porous bodies and no true tissues.
2-sided:
Bilateral symmetry.
ball dents
Refers to the choanocytes of sponges.
