Cambrian period 530 MYA when did invertebrate animals inhabit Earths ocean largely
vertebrates get their name from vertebrae, the series of bones that make up the backbone
365 MYA when did one lineage of vertebrates colonize land
amphibians, reptiles, and mammals what modern animals did vertebrates give rise to
chordates are bilaterian animals that belong to the clade of animals known as
Deuterostomia
all vertebrates and two groups of what do chordates comprise of
invertebrates
1. Urochordates what are the two groups of invertebrates that chordates consist of
2. Cephalochordates
from top to bottom label purple marks on the tree
1. notochord
2. vertebrae
3. jaws, mineralized skeleton
4. lungs or lung derivatives
5. lobed fins
6. limbs with digits
7. amniotic eggss
8. milk
1. Notochord what four traits do all chordates share
2. Dorsal, hollow nerve cord
3. Pharyngeal slits or clefts
4. Muscular, post-anal tail
, from left to right label
the bottom end is post anal tail
the bottom top is muscle
segments the brain
pointed end is anus
the middle organe is notochord
the yellow is dorsal hollow nerve
cord
the brown to the right is
phyrangeal slits or cleft
all the way to the right is the mouth
notochord a longitudinal, flexible rod between the digestive tube and nerve cord
provides skeletal support what is the purpose of the notochord
In most vertebrates, a more what is the notochord like in most vertebrates
complex, jointed skeleton
develops, and the adult retains
only remnants of the
embryonic notochord
a plate of ectoderm what does the nerve cord develop from
that rolls into a tube dorsal
to the notochord
the central nervous what does the nerve cord develop into
system: the brain and the spinal cord
In all chordate embryos, grooves form along
pharyngeal clefts
the outer surface of the pharynx called
pharyngeal slits what do pharyngeal clefts develop into in most chordates
Suspension-feeding structures in what are the functions of the pharyngeal slits
many invertebrate
chordates
Gas exchange in vertebrates
(except vertebrates with
limbs, the tetrapods)
Develop into parts of the ear,
head, and neck in
tetrapods
posterior to the anus where is the tail in chordates
The tail contains skeletal elements what does the tail contain and chordates and what is its purpose
and muscles
It provides propelling force
in many aquatic species
(Cephalochordata) are named for their bladelike shape
lancelets They are marine suspension feeders that retain characteristics of
the chordate body plan as adults
more closely related to chordates what are tunicates closely related to and resemble
than lancelets.
they resemble chordates during
their larval stage
