Animal Architecture Flashcards
Cnidarians are characterized by a _________ grade of organization.
cell-tissue
The majority of organisms exhibit the ________ grade of organization.
organ system
Larger size attained by more evolutionarily advanced organisms prevented effective
respiration by cells deep within a body
The study of tissues is known as
histology
Which of the following is not one of the four types of tissues?
mesodermal
The fibers of connective tissue are embedded in the matrix, which is also known as
ground substance
Which of the following is not a characteristic of connective tissue?
basement membrane
Epithelium may be modified to form
glands
Bilateral symmetry is associated with ____, localization of sensory structures in a distinct head region.
cephalization
Blood, lymph, and tissue fluid are classified as _________ tissue.
vascular
Fluid within a cell is known as the
intracellular fluid
A fibrous protein that is particularly abundant in many types of connective tissues is
collagen
Which of the following is a pseudocoelomate animal?
nematode
Larger animals use more energy, scaled to body weight, than a small animal for locomotion.
false
At the base of an epithelial tissue is the basement membrane.
true
Vertebrates have only two types of striated muscle; skeletal and smooth.
false
You are a metazoan.
true
Stratified epithelia are typically only found in vertebrate animals
true
If you get a paper cut, and it bleeds, you must have cut through the epidermis into the underlying tissues.
true
Sea Walnuts(ctenophores) may be described as biradial symmetry because their bodies are mostly radial in form, but have paired tentacles.
true
Terms which best describe your nose would be anterior, ventral, and medial,
true
If a section of an animal was made such that it is cut into ventral and dorsal halves, this would be a frontal section.
true
Animals that possess a true coelom have a body cavity lined completely with mesoderm.
true
In animals with enterocoelous development, the coelom comes from pouches of the archenteron.
true
Another term for metamere is coelom.
false
Stratified columnar epithelium lines the gut, and is specialized for absorbing nutrients.
false
Transitional epithelium is a type of stratified epithelium, and is found in the urinary tract of vertebrates.
false
Organisms that can be divided along the sagital line into left and right halves that are mirror images are said to have ______ symmetry
bilateral
Those parts of the body that are farther rom the middle of the body are said to be _____
distal
Which of the following is not characteristic of protostomes?
radial cleavage
Which of the following lacks mesoderm?
primarily radiate animals
The ____ plane is the imaginary plane dividing a bilateral organism into left and right halves.
sagittal
