These are segments of bone or other hard substance arranged into a backbone
What are vertebrae?
Species in this phylum have some type of backbone and a dorsal nerve chord
What is chordata?
A primary example of Subphylum Urochordata is this species?
What is a sea squirt?
This is how a sea squirt eats
What is siphoning (like a sponge) water through opening (oral) and expelling thru atrial opening?
These nerves (1) take stimuli information to brain and these nerves (2) take messages to body to tell it what to do
What are (1) sensory nerves and (2) motor nerves?
This surrounds both compact and spongy bone tissue; contains blood vessels that supply oxygen and nutrients to the bone; also contains nerves
What is periosteum?
Subphylum is determined by the outcome of this
What is the notochord?
A primary example of Subphylum Cephalochordata is this species
What is a lancelet?
These are the four components of bone tissue
What are compact bone tissue, spongy bone tissue, periosteum, and bone marrow?
The type of fertilization where an egg has no shell
What is external fertilization?
This is soft tissue inside bone that produces blood cells
What is bone marrow?
The three ways that bones help
What are support, produce blood cells, and stores excess minerals for chemistry of organism?
A primary example of Subphylum Vertebrata is this species
What is a fish (or an amphibian, reptile, bird, mammal)?
This is the system that pumps blood throughout the body?
What is the circulatory system?
The differences among (1) oviparous, (2) viviparous, and (3) ovoviviparous
What are (1 oviparous) occurs in an egg hatched outside female body, (2 viviparous) occurs inside female; placenta provides nutrients to offspring, and (3 ovoviviparous) embryos develop within the mother but depend entirely on yolk sac - no nourishment from the mother?
This is composed of collagen fibers like bone tissue but slightly different. It is not reinforced with calcium salts; its more flexible but weaker.
What is cartilage?
The optic lobes receive signals from receptors in this body part
What is the eye?
This is the skeleton that has limbs attached to it
What is the appendicular skeleton?
This is the component of blood that carries oxygen and gives the cell its red color
What is hemoglobin?
Species in this vertebrate class have an electrical field sensor and include sharks, skates, rays
What is class chondrichthyes?
This is lobes of the brain that integrate sensory info and coordinate response to info
What is the cerebrum?
This controls involuntary actions and refines muscle movements
What is the cerebellum?
This is the skeleton that supports and protects the head, neck, trunk, and vertical column
What is the axial skeleton?
The medulla oblongata controls vital functions in these two body systems
What are the circulatory and respiratory systems?
Amphibians utilize this type of fertilization and development after fertilization
What are external fertilization and oviparous development?
