Q

Sub sections of colliculi, and locations

A

Inferior - Sound reflex

Superior - Sight reflex

23
Q

Sections and location of the brain stem

A

Pons, midbrain and medulla. Located below the forebrain

24
Q

Sections and location of the forebrain

A

Basically everything other than hindbrain and midbrain

25
Q

Sections and location of midbrain

A

Cerebral aqueducts, cerebral penduncles, sup/inf colliculi, substantia nigra
Located above/in the top of the brainstem

26
Q

Sections and location of hindbrain

A

Pons, cerebellum, medulla, fourth ventricle, located below/around midbrain

27
Q

Function/location of cerebral aqueduct

A

Connects 3rd & 4th ventricle, runs between midbrain and colliculi

28
Q

Function/location of cerebral peduncles

A

Connects brainsem to thalamus. Anterior section of the midbrain

29
Q

All ventricles

A

Lateral ventricle, 3rd & 4th ventricles

30
Q

Location of 4th ventricle

A

From thalamus to cerebellum

31
Q

Location of 3rd ventricle

A

Between/around lobes of thalamus

32
Q

Direction of association fibres

A

Front and back, i.e. arcuate fassiculus

33
Q

Direction of projection fibres

A

Up and down, i.e. internal capsule

34
Q

Direction of commissural fibres

A

Right and left, i.e. corpus callosum

35
Q

45 degree interventricular sulcus

A

ventral view

36
Q

Vertical interventricular sulcus

A

dorsal view

37
Q

Great veins exposed

A

Dorsal view

38
Q

Vena cava of sheep heart

A

R. Ant, middle post, L. Ant

39
Q

External braching of systemic arteries

A

Brachiocephalic and aorta

40
Q

Blood vessels exposed on ventral view

A

Pulmonary trunk and aorta

41
Q

Blood vessels exposed on dorsal view

A

Vena cava & fatpads

42
Q

Aortic valve ant. or post. to pulmonary valve

A

Dorsal to pulmonary valve

43
Q

Trabeculae found…

A

In the auricles and ventricles

44
Q

What is fossa ovalis, and what is child equivalent

A

Between two atria, foramen ovale

45
Q

What is ligementum arteriosum and what is child equivalent

A

Connects elastic arteries, ductus arteriosus

46
Q

First branch of aorta

A

Coronary ostia

47
Q

Function of fossa ovale function

A

Allows blood to cross from right to left atrium in child heart

48
Q

Function of ductus arteriosus

A

connects arteries, because lungs don’t work in fetus

49
Q

Why does the fossa ovale close

A

Because upon breathing, L atrial pressure exceeds right atrial pressure and forces it shut

50
Q

Why does the ductus arteriosus close (becoming ligamentum arteriosum)

A

Because smooth muscle contracts

51
Q

Function/location of cingulate gyrus

A

Above corpus callosum, fight flight information, connects to frontal lobe

52
Q

Number of coronary ostia

A

2

53
Q

Ligamentum arteriosus visible from dorsal or ventral view

A

dorsal

54
Q

What is the moderator band and where is it found?

A

Found from wall to wall of the right ventricle, muscle purkinjie fibres for conduction
