Lesson 1 Flashcards
It is the study of vertebrates, function, and evolution
CVA
How many organ system are found in a vertebrae
9
What are the four anatomy parts of a vertebrae
Notochord
Dorsal hollow nerve cord
Pharyngeal slits
Post anal tail
Notochord is located above the —-
Spinal cord
It forms support for the body and guides the placement of the CNS
Notochord
Notochord is present until
Early embryonic stage
It developes into the CNS; brain and SC
Dorsal hollow nerve cord
DHNC is found above the —-
Notochord
It is the opening in the pharynx
Pharyngeal slits
Pharyngeal slits
Aquatic -
Teresstrial -
Aquatic - Gill arch
Teresstrial - jaw and inner ear bone
Post anal tail
Aquatic -
Terrestrial -
Aquatic - locomotion and stability
Teresstrial - balance, courting, and signaling
It surrounds and protect the main nerv; from neck to tail
Vertebral column
The vertebral column is made up of individual bones called ___
Vertebra/vertebrae
What are the two main part of a vertebrae
Centrum
Neural arch
Part of a vertebrae that provides support and weight bearing capacity, as weel as facilitates communication
Centrum
It forms the dorsal part of a vertebrae and is the attachment site for ligaments and muscle
Neural arch
Studies evolutionary relationship, common ancestry and evolutionary branching
Phylogeny
Study of fossil records
Paleontology
A behavior or structure that developes somtime in the evolutionary history to help survive
Functional adaptation
Study the stages of embryonic development
Embryology
What are the 3 germ layers?
Ectoderm, mesoderm, and endoderm
Outermost layer; epidermis, nerves, hair, nails, and nervous system
Ectoderm
Middle layer; skeletal and circulatory systems, tissues, reproductive organs, kidney and dermis
Mesoderm
