always* when you were baby your internal illiac artery

A

your internal illiac artery was a big vessel and it didnt stop at the superior vessicular it went the inside of your belly went up your belly button and to the placenta, it was your umbilical artery your connection with mom went through your internal illiac artery-

Q

the subclavian artery becomes the

A

axillary artery Sublcavian AA.

pass into each arm, becomin Axillary A. past clavicle.

31
Q

axillary artery has how many branches

A

6 branches, organized relative to the pectoralis minor muscle

32
Q

6 banches of AXILLARY ARTERY.

A

1 before pectoralis minor: supreme thoracic a.

2 deep to pectoralis minor: thoracoacromial a. and lateral thoracic a.

3 beyond pectoralis minor: subscapular a GOES FIRST, anterior humeral circumflex a., posterior humeral circumflex a., .

33
Q

Subclavian
Branches:
three major branches

A

Vertebral A.
Internal Thoracic A.
Thyrocervical trunk

34
Q

what passes through transervere formmane/cervical vertbrae

A

the FIRST branch of the subclavian called the vertebral artery goes to base of skull jump thru the foramen magnum, go insided cranial cavity and give blood to brain its also carotids job

35
Q

Internal Thoracic A.
Thyrocervical trunk
branches of subclavian

A

pretty much branch off the same level one is superior (thyrocervical neck-thyroid gland) one inferior or internal theoric artery, near ribcage very useful down inside of ribcage Anastomosis of Internal Thoracic Artery with External Iliac Artery

36
Q

Anastomosis of Internal Thoracic Artery ??

A

branches of to the rib cage which form an anastomsis from the aorta.. actually hooks up with blood vessels from the inside of your abdominal cavity called the epigastric artery thats right above your guts

37
Q

Ateries and nerves tend to

A

run more deeply – where it’s safer.

38
Q

what is the first branch of subclavian

A

the vertebral arteries

39
Q

axillary artery

A

goes through axilla (armpit) slightly vulnerable place, protected in the front by your pectoralis major muscle, behind by scapula, side by humerous, medial side by your ribcage, under protected by nothing loose connective tissue & fat

40
Q

Brachial Artery

–>?

A

radial & ulnar

41
Q

Ulnar Artery–>

A

Common Interosseous A

42
Q

Arch–>

A

Common Palmar

Digital AA.

45
Q

axillary artery..?“1 - 2 - 3” KNOW THIS IN ORDER

A

1 before pectoralis minor: supreme thoracic a.

2 deep to pectoralis minor: thoracoacromial a. and lateral thoracic a.

3 beyond pectoralis minor: anterior humeral circumflex a., posterior humeral circumflex a., and subscapular a.

46
Q

PAIRED ARTERIES OF THE BODY WALL: ABDOMEN

A 
Lumbar arteries (5)
Renal arteries
Gonadal (ovarian, testicular) arteries
Common Iliac Arteries; Branches:
External Iliac Arteries
Internal Iliac Arteries
47
Q

Body wall veins

parallel the??

A

arteries

48
Q

what are portal systems

A

A circulatory system (set of tubes) with a capillary bed at BOTH ends.

49
Q

what are example of portal systems?

A

Foregut: Splenic Vein (= Lienic Vein)

Midgut: Superior Mesenteric Vein

Hindgut: Inferior Mesenteric Vein

All dump into Hepatic Portal Vein, which goes to Liver.

50
Q

Falx cerebri

A

The falx cerebri is also known as the cerebral falx, named from its sickle-like form. It is a large, crescent-shaped fold of meningeal layer of dura mater that descends vertically in the longitudinal fissure between the cerebral hemispheres.

51
Q

Tentorium cerebelli

A

The tentorium cerebelli or cerebellar tentorium (Latin: “tent of the cerebellum”) is an extension of the dura mater that separates the cerebellum from the inferior portion of the occipital lobes.

52
Q

Venus Sinuses

A

The dural venous sinuses (also called dural sinuses, cerebral sinuses, or cranial sinuses) are venous channels found between layers of dura mater in the brain.

53
Q

Vasculature:

Arterial Supply of the brain

A

Circulosus Arteriosus Cerebri

54
Q

what are the tributaties of the Circulosus Arteriosus Cerebri?

A
  • Right and Left Internal Carotid Arteries

- Basilar Artery formed from right and left Vertebral Arteries

55
Q

Circulosus Arteriosus Cerebri

Major Branches

A

Anterior Cerebral AA.
Middle Cerebral AA.
Posterior Cerebral AA.

56
Q

Basilar Artery Branches:

A

Superior Cerebellar AA.
Middle Cerebellar AA.
Internal Cerebellar AA.

57
Q

which branches of the axillary artery are similar to which of the femoral

A

the circumflexes are similar

58
Q

of the six branches of the axillary? which other ones form an anastomisis which four hook up in an astomisis besides the circumflex?

A

they hook up with each other lol
the supreme thoracicand lateral probably hook up with each other
the thoracacromion is part of what? the acromion so the thoracoacromial a. and the subscapular a. hook up too

59
Q

there are branches of both the arm

A

sublclavian and axially

60
Q

the internal thoracic hooks up with the

A

superior epigastric which hooks up with the inferior epigastric which comes off of the illiar thats nuts lmao

61
Q

big vein that exits your head

A

jugular goes up jugular foramen same as vagus nerve

62
Q

veins that drain your brain are

A

sloshy they are defined by spaces in the dura- venus blood sloshes around venus sinuses

63
Q

one big sinus by the falx cerberi

A

called superior saggital, also inferior sagital sinus midline and unpaired

64
Q

when the inferior sagital hits the Tentorium cerebelli

A

hits straight back the the supeior called the straight sinus, all the sinus converage together by the jugular foramen

65
Q

know right and left transverse

A

go to the side curves back its called the sigmond goes right past the temporal bone the petrous portion the petrous sinus they all head to the jug foramen blood falls to head all converages by the jug foramen

66
Q

all venus sinus converages by the jug foramen

A

the cavernous sinus penis of the brain looks like erectile tissue sort of spongy-

67
Q

caverous sinus to the heart?

A

goes to jugular foramen, jugular vein , unite with the subclavian, becomes the brachiocephalic vein goes to the superior vena cava and then youre at the

68
Q

major blood vessels that derive over the third aortic arch

A

the carotid eternal and internal(head)

69
Q

loop artery that wraps around the pitutary gland, the base of the brain, sends all the branches to the underside of the brain

A

if its blocked one way can go the other

first branch of subclavian vertebral artery enter right and left into your skull by foramen magneu,

70
Q

right and left verterbral artery unite to form?

A

forms the basillar artery dumps into the loop

71
Q

circle artery is called?

A

Circulosus Arteriosus Cerebri

72
Q

tributaries of Circulosus Arteriosus Cerebri

A

Right and Left Internal Carotid Arteries

Basilar Artery FUSION of right and left vertebral arteries formed from right and left Vertebral Arteries

73
Q

whats a stroke

A

farther you go out the arteries less chance of an astomosis, brain tissue that is supplying doesnt get blood
