The trabecular arteries are the name of the branches of the splenic artery after it passes into the trabeculae of the spleen, where it branches.When these arteries then reach the white pulp, and become covered with periarteriolar lymphoid sheaths, the name changes again to central arteries (or central arterioles).
Splenic artery aneurysms are rare, but still the third most common abdominal aneurysm, after aneurysms of the abdominal aorta and iliac arteries. [2] [3] They may occur in pregnant women in the third trimester and rupture carries a maternal mortality of greater than 50% and a fetal mortality of 70 to 90%.
Hilum of the liver. In human anatomy, the hilum (/ ˈ h aɪ l ə m /; pl.: hila), sometimes formerly called a hilus (/ ˈ h aɪ l ə s /; pl.: hili), is a depression or fissure where structures such as blood vessels and nerves enter an organ. Examples include: Hilum of kidney, admits the renal artery, vein, ureter, and nerves
Periarteriolar lymphoid sheaths (or periarterial lymphatic sheaths, or PALS) are a portion of the white pulp of the spleen.They are populated largely by T cells and surround central arteries within the spleen; the PALS T-cells are presented with blood borne antigens via myeloid dendritic cells.
Splenic infarct appears as a wedge-shaped area of splenic tissue with the apex pointed toward the hilum and the base of the splenic capsule. As the infarction matures, the affected tissue may normalize, liquefy or become contracted or scarred. Abdominal ultrasound has also been used to detect splenic infarction. Ultrasound findings of the ...
The splenic lymph nodes are found at the splenic hilum and in relation to the tail of the pancreas (pancreaticolienal lymph nodes). [1] [2] Their afferents are derived from the stomach, spleen, and pancreas. The splenic lymph nodes empty into the suprapancreatic, infrapancreatic and omental lymph nodes, which then drain to the coeliac nodes and ...
A Wiggers diagram, named after its developer, Carl Wiggers, is a unique diagram that has been used in teaching cardiac physiology for more than a century. [1] [2] In the Wiggers diagram, the X-axis is used to plot time subdivided into the cardiac phases, while the Y-axis typically contains the following on a single grid: Blood pressure. Aortic ...
The cardiovascular centre affects changes to the heart rate by sending a nerve impulse to the cardiac pacemaker via two sets of nerves: sympathetic fibres, part of the autonomic nervous system, to make heart rate faster. the vagus nerve, part of the parasympathetic branch of the autonomic nervous system, to lower heart rate.
