    Study Notes

    Pancreas

    • The pancreas is the only organ that has both endocrine and exocrine functions.
    • Endocrine glands are those that secrete hormones directly into the blood.
    • Exocrine glands are those that secrete substances through ducts.

    Spleen

    • The spleen is responsible for:
      • Blood filtration
      • Immune function

    Superior Mesenteric Artery

    • The superior mesenteric artery supplies blood to:
      • The majority of the small intestine
      • Part of the large intestine

    Coeliac Trunk

    • The coeliac trunk is a major blood vessel that branches directly off the aorta.
    • The coeliac trunk supplies blood to:
      • The stomach
      • The spleen
      • The liver
      • The pancreas

    Portal Vein

    • The portal vein is responsible for carrying blood from the digestive organs to the liver.

    Hormones of the Pancreas

    • The pancreas is responsible for the production of several hormones, including:
      • Insulin
      • Glucagon
      • Somatostatin
    • Aldosterone is produced by the adrenal glands, not the pancreas.

    Red Pulp of the Spleen

    • The spleen is composed of two types of tissue:
      • White pulp - functions primarily in immune response
      • Red pulp - functions primarily in blood filtration

    Splenic Vein

    • The splenic vein carries blood from the spleen to the liver

    Left Atrioventricular Valve

    • Also called the mitral valve.
    • It allows oxygenated blood flow from the left atrium into the left ventricle.
    • Open during ventricle systole.

    Superior Thoracic Aperture

    • The superior thoracic aperture is the opening at the top of the thorax, the region between the neck and the abdomen. It is formed by the first rib, the first thoracic vertebra, and the manubrium of the sternum.
    • The following structures pass through here:
      • Right and left common carotid artery
      • Left and right subclavian veins
      • Left and right subclavian arteries
      • Left and right vagus nerves
      • Trachea
      • Esophagus
      • Thoracic duct (largest lymphatic vessel)

    Coeliac Trunk and Superior Mesenteric Artery

    • Anastomoses between these arterial branches occur at the pyloric part of the stomach.

    Geniculate Ganglion

    • Located inside the facial canal.

    Lingual Papillae

    • Foliate papillae are located along the lateral sides of the tongue body.
    • Vallate papillae are located at the back of the tongue. The median sulcus divides the vallate papillae and the lingual tonsil.
    • Lingual papillae are located on the dorsal surface of the tongue, not the inferior surface.
