*sup mesenteric
what are three branches of arch of aorta
1.brachiocephalic trunk-supplies arm/head
2. common carotid
3. subclavian
what does superior mesenteric artery supply
lower half of
duodenum, small part of pancreas, small intestine (except the
upper half of duodenum), cecum, appendix, ascending colon,
and the right two-thirds of transverse colon.
three branches of celiac trunk
- splenic: spleen
- common hepatic: liver
- left gastric; stomach
- radial
- common interossus
- ulnar
- deep palmar arch
- superficial palmar arch: supplies palmar aponeurosis
- palmar digital
where does right vertebral artery (branch of subclavian) go
thru transverse processes of cervicalvertebrae, enter brain via foramen magnum.
supplies spinal cord, medulla, cerebellum
what do branches of thoracic aorta become
intercostal arteries
1.thryocerical trunk: supplies anterior portion of axilla
- thoracoacromial: supplies anterior wall axilla
- posteiror circumflex humeral
- anterior circumflex humeral
both surround surgical neck humeros
what does brachial artery branch into
radial and ulnar
label tehse arteries
1.subclavian (from brachipcephalic trunk)
- axillary
- brachial
- radial
- ulnar
where do common ilia arteries divide into internal/external iliac arteries
sacroliaci joitns
- right vertebral
- right subclavian
- right external carotid
- right internal carotid
- right common carotid
- brachiocephalic trunk
where does sigmoid arteries supply
sigmoid colon
**inf mesenteric
what does renal artery supply
kidney, adrenals, uterus
what are the parietal and visceral groups of abdominal aorta?
1.parietal (somatic): supply diaphragm and posterior abdo wall. lumbar arteries and inferior phrenic arteries
- visceral branches: supply abdo viscera. celiac trunk, common hepatic, splenic branches
what does the gastroomental artery supply
greater curvature of stomach. btw stomach and greater omentum
branch of splenic
- vertebral: supplies posterior circulation thru transverse foramen in cervical verts
- internal thoracic: supply chest wlal
- brachial supplies ant compartment arm
- deep brachial (profunda) travles with radial nerve, behind humerus. supplies posterior arm
what does celiac trunk arteries supply
abdominal esophagus, stomach, liver, gall bladder, spleen,
most of the pancreas, and upper half of the duodenum.
- internal iliac
- external iliac
- superior gluteal
- inferior gluteal
- deep femoral
- femoral
- popliteal
what happens when external iliac artery passes thru inguinal ligament?
becomes femoral artery
where does left colic artery supply
descending colon
**inf mesenteric
basilar artery
made of R and L vertebral artries. supplies pons/cerebellum. divides into posterior cerebral arteries that supply cerebrum
what happens when inferior mesenteric artery bifurcates
divides into internal and external iliac arteries
- femoral
- popliteal
- anterior tibial
4.posterior tibial - fibular
- brachiocephalic trunk
- common carotid
- subclavian
4.internal thoracic artiers (behind chest wall) - intercostal
what do gonadal arteries supply
ovaries/testes
top: arch of aorta
mid: thoracic aorta
low: abdominal aorta
axillary artery
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.
- 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.
- dorsal pedis
- dorsal digital
- medial plantar
- lateral plantar
- plantar digital
1.common hepatic
2. greater curvature
3. left gastric
4. splenic
what does short gastric artery supply
lesser curvature
branches internal iliac artery
parietal: superior/inf gluteal artiers, obturator artery, internal pudendal
visceral: pelvic viscera
what are the three midline arteries of the abdomen
1.cephalic trunk-supplies foregut
2.superior mesenteric-supplies midgut
3.inferior mesenteric-supplies hind gut
explain the branches of brachiocephalic artery which supply the head
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
what are the main branches of axillary artery
- thoracoacromial: anterior wall axilla
- lateral thoracic: medial wall axilla
- subscapular: scapular region
- anterior and posterior circumflex: shoulder/deltoid region
