Q

What is a dorsal tubular nerve chord?

A

A hollow chord
the antieror end becomes enlarged to form the brain
the nervous chord is protected by the neutral arches and th brain is protected by the cranium
Helps us move and picks up sensory and makes solutions.

25
Q

What are HOX genes?

A

Master genes of development regulating the expression of subordinate genes

26
Q

What do HOX genes do?

A

Regulate neuralcrest cells
Then forms Ectodermal Placodes
New Traits

27
Q

Otic Vessical?

A

Sends vibrations back to brain

28
Q

What does the hind brain regulate?

A

Balance

29
Q

What does the middle brain regulate?

A

Emotional

30
Q

Scents connect to which part of the brain?

A

Middle Brain

31
Q

Vision connects to which part of the brain?

A

front part

32
Q

What is the thing that protects the brain?

A

Cranium

33
Q

What is an eye?

A

Gives visual to brain

34
Q

Where does blood go through?

A

The gill slits
Runs back and forth from intestines
And the heart

35
Q

What kind of heart does it have?

A

Chambered

Increases the energy level

36
Q

What is the ohfactory bulb?

A

smell sense

37
Q

Where does the ohfactory bulb connect to?

A

Middle Brain

38
Q

Myomeres?

A

Muscles

39
Q

What are the 4 traits to the verttabrata?

A

Tripartite Brain
Cranium
Chambered HEart
W Shaped Myomeres

40
Q

How many HOX genes did Vertebrata have?

A

4

41
Q

In vertebrates, what becomes more muscular?

A

Its jaw

Musclular pharynx

42
Q

How does vertebrates eat?

A

Opens its mouth to have water and food particles go in and the water goes out the gills
Jaw bones are started here

43
Q

Where do jaws come from?

A

Gill slits go from having 7 of them to 5 and 2 becomes jaws because the gills were hitting the cranium and the cranium moved it to the upper mouth part and becomes a gill arch. (Same for second but it goes to the lower mouth)

44
Q

What is a chambered heart?

A

It seperates oxygenated blood and dioxyngenated blood

45
Q

WHat is the difference between V shaped and W shaped myomere

A

V: Has only a concentrated strength (cephalochordata)
W: Can have more strength in more parts of hte party (Vertebrata)

46
Q

What is the otic Vessicle used for?

A

hearing

47
Q

What part of the brain does the otic vessicle connect to?

A

hind brain

48
Q

WHat is the eye for?

A

Vision senses

49
Q

What part of the brain connects to the eye?

A

Front brain

50
Q

What is the olfactory bulb for?

A

smell

51
Q

What part of the brain does the olfactory bulb connect to?

A

middle brain

52
Q

What is the front of the brain for?

A

vision

53

What is the middle of the brain for?

A

emotions

54
Q

What is the hind brain for?

A

hearing
