P2 ANATOMY Flashcards
in what abdominal region the spleen is spleen found
left hypochondrium , partly in epigastrium
Against which ribs the spleen lies
9th , 10th , 11th
Ligament that contains short gastric vessels
gastrosplenic ligament
Ligament that extends from hilum to Lt kidney
lienorenal ligament
ligament that prevent splenic downward enlargement
phrenicocolic
mention the 4 impressions of the visceral surface of spleen
- gastric
- colic
- renal
- pancreatic
surface that separates the spleen from the costo- diaphragmatic recess of pleura, lung and ribs
Diaphragmatic surface
Arterial supply of the spleen
splenic artery
splenic Art. is a branch of
Celiac trunk
small branches of which Art. Supplies neck , body & tail of pancreas
small branches of splenic Art.
Branches of splenic Art. that pass through gastro-splenic ligament
short gastric arteries
short gastric arteries supply
fundus of the stomach
branch of splenic Art. that runs along greater curvature
left gastro-omental Art.
Arteries in the white pulp are known as
central arteries
central arteries are branches of
Trabecular artery
branch of central arteries that supplies lymphoid nodules & dense lymphoid tissue
Follicular arteries
Arteries in red pulp
penicillar arteries
venous drainage of spleen is done by
splenic sinusoids
from splenic sinusoids , blood drains into
Trabecular veins
vein that drains into hepatic portal vein
splenic vein
external surface lining of splenic capsule
lined by mesothelium
nodules of white pulp are mainly composed of
B lymphocytes
tissues known as
splenic/billroth’s cords are present in
red pulp
splenic cords in the red pulp contain
- lymphocytes
- macrophages
- granulocytes
- plasma cells
- RBCs ,& platelets
Poorly delineated area between white & red pulp
marginal zone
main function of red pulp
Filter RBCs & reserve monocytes
main function of white pulp
help in active immune response
Palpable spleen is always
Pathological
incase of splenectomy , Pts will develop from
- bacterial sepsis
- abnormal RBCs in circulation
