CVA FINALS STUDY GUIDE

Identify the SPLITS defined by the presence or absence of a jaw

A

Identify the SPLITS defined by the presence or absence of an amnion

F

Identify the SPLITS defined by the presence or absence of four jointed, muscular limbs

E

Identify the SPLITS defined by the presence or absence of a bony skeleton

C

Identify the SPLITS defined by the presence or absence of a synapsid skull

G

T/F: Urochordates and hemichordates are not true chordates bc they do not possess all 5 chordate chara.s simultaneously at any point in their life cycle; instead, they are protochordates

F

Ambulacraria

Deuterostome sister clade to Chordata; incl Hemichordata and Echinodermata

Hemichordata

Protochordates w/ pharyngeal slits and postanal tail, but no notochord; incl acorn worms and pterobranchs

Cephalochordata

Basal chordates; incl lancelets and Amphioxus

Urochordata

Chordates w/ tough outer covering called a “tunic”; incl sea squirts and salps

T/F: Adaptations that inc SA usually act to minimize an exchange rate

F

What is the outer, protective layer of the epidermis found in 4pods but not fish?

stratum corneum

T/F: True horns consist of a bony core surrounded by a heavily keratinized epidermal sheath. True horns are found in the cattle and antelope family (Bovid) and never shed

T

T/F: Body mass is proportional to body vol., which inc much faster than body SA bc of the laws of geometry.

T

Zygote

Fertilized egg, consisting of a 1x cell

Gastrula

1st fully triploblast stage; gut starts to form

Morula

Solid ball of cells

Blastula

Hollow ball of cells, not yet triploblast

T/F: Many of the repeated units of the vert. body, such as the pharyngeal arches or the vertebrae, arise from segments of the embryo called coeloms

F

Which are the guts for a carnivore?

A & C
