basilar artery

A

made of R and L vertebral artries. supplies pons/cerebellum. divides into posterior cerebral arteries that supply cerebrum

30

33
Q

what do gonadal arteries supply

A

ovaries/testes

34
Q
A

top: arch of aorta
mid: thoracic aorta
low: abdominal aorta

35
Q

axillary artery

A

is the continuation of the subclavian artery
within the axilla

extends between the lateral
border of the first rib and the lower margin of teres major muscle. The
main branches of axillary artery include:
1. The thoracoacromial artery mainly supplies the anterior wall of
axilla.
2. The lateral thoracic artery supplies the medial wall of axilla.
3. The subscapular artery contributes in blood supply of the scapular
region.

  1. The anterior and posterior circumflex humeral arteries that wind
    around the surgical neck of the humerus mainly assist in
    supplying deltoid muscle and shoulder JOmt.
36
Q
A
  1. dorsal pedis
  2. dorsal digital
  3. medial plantar
  4. lateral plantar
  5. plantar digital
37
Q
A

1.common hepatic
2. greater curvature
3. left gastric
4. splenic

38
Q

what does short gastric artery supply

A

lesser curvature

39
Q

branches internal iliac artery

A

parietal: superior/inf gluteal artiers, obturator artery, internal pudendal

visceral: pelvic viscera

40
Q

what are the three midline arteries of the abdomen

A

1.cephalic trunk-supplies foregut

2.superior mesenteric-supplies midgut

3.inferior mesenteric-supplies hind gut

41
Q

explain the branches of brachiocephalic artery which supply the head

A

subclavian. divides into internal thoraic, thyrocervical and vertebral artery. vertebral artery supplies brainstem, posterior cerebrum (basilary artery, posterior cerebral)

common carotid divides into internal and external carotid.
Internal carotid forms circle of willis, splits in opthalmic, anterior cerebral, and middle cerebral arteries

external carotid supplies head/neck outside cranial cavity. branches include maxillary, superficial temporal, occipital, facial, lingual, superior thyroid

42
Q

what are the main branches of axillary artery

A
  1. thoracoacromial: anterior wall axilla
  2. lateral thoracic: medial wall axilla
  3. subscapular: scapular region
  4. anterior and posterior circumflex: shoulder/deltoid region
