Where is the spleen located?
Key facts about the spleen Definition An intraperitoneal lymphoid organ found Location Left hypochondriac region (left upper qu Structure Capsule, trabeculae, white pulp, red pul Function Immune surveillance, proliferation and m Neurovascular supply Artery: splenic artery Vein: splenic vei
What are the borders of the splenic hilum?
The splenic hilum is found in the central part of this surface. The spleen has three borders (superior, inferior, and anterior) as well as two extremities (anterior and posterior). The superior border bounds the gastric area, the inferior border bounds the renal area and the anterior border bounds the colic area.
What connects the hilum of the spleen with the stomach?
The gastrosplenic ligament connects the hilum with the greater curvature of the stomach. It contains the short gastric vessels and left gastroomental (gastroepiploic) arteries and veins. The splenorenal ligament connects the hilum of the spleen with the left kidney.
What innervates the spleen?
The spleen is innervated by autonomic nerves from the celiac plexus, which supply the spleen with both sympathetic and parasympathetic nerves. These nerves form the splenic plexus which reaches the splenic hilum traveling along the splenic artery and its branches. The spleen is a secondary lymphoid organ.
Which kidney is medial to the spleen?
Medial to the spleen is the left kidney; superior is the diaphragm, while inferiorly it rests directly on the left colic flexure (splenic flexure).
Is the spleen anterior or posterior to the stomach?
More precisely, the spleen is located posterior to the stomach and anterior to the left hemidiaphragm at the level of ribs 9-10. Medial to the spleen is the left kidney; superior is the diaphragm, while inferiorly it rests directly on the left colic flexure (splenic flexure).
What are the 3 borders of the spleen?
The spleen has three borders (superior, inferior, and anterior) as well as two extremities (anterior and posterior). The superior border bounds the gastric area, the inferior border bounds the renal area and the anterior border bounds the colic area.
What is the Brown mantidfly?
The alternating yellow, black, and brown bands on the abdomen and hairless body seem like obvious indicators. Even the vein pattern on its wings is similar to that found in the wasp family. There is a bit more physiology to the Brown Mantidfly though, and closer examination reveals a strange mix of features not often seen in one insect.
Do mantidflies lay eggs in spider eggs?
Once sealed inside, the Mantidfly larvae begin feasting on the spider eggs. Adult Brown Mantidflies emerge from the spider’s egg sac once they have fully matured. Sightings of Brown Mantidflies are rare, but when they are spotted, they certainly leave an impression.
What are the histological features of the spleen?
The spleen has a unique location, embryological development and histological structure that differs significantly from other lymphoid organs. Special histological features define several important functions of the spleen, such as filtering blood, maintaining immune response balance and recycling iron.
The spleen is a fist sized organ located in the left upper quadrant of the abdomen. It is the largest lymphoid organ and thus the largest filter of blood in the human body. The spleen has a unique location, embryological development and histological structure that differs significantly from other lymphoid organs.
Where is the hilum of the spleen located?
The hilum is located on the visceral surface of the spleen and runs obliquely from the posterior extremity to the anterior extremity. It is the point of entry for the splenic arteries and nerves. The splenic veins and lymphatics leave the spleen from that point as well.
What is the histological arrangement of the spleen?
Histology of the Spleen. The reticuloendothelial system is an expansive network that encompasses the haematopoietic centres, the formed elements they produce, as well as the conduits that transports them. One of the key structures of this system is the spleen. The main focus of this article is the histological arrangement of the spleen.
What are the odd numbers for the spleen?
Considering that the spleen itself is an odd organ, the odd numbers 1, 3, 5, 7, 9, and 11 can be used to recall the dimension, weight, and location of the organ. Using metric units, the spleen is 1 inch x 3 inches x 5 inches in three dimensions, 7 ounces in weight, and located deep to the 9th to 11th ribs.
