The part of the olfactory cortex that is on the temporal lobe covers the area of the uncus, which leads into the two significant clinical aspects: herniations and seizures Herniations of the brain can occur if increased intracranial pressure due to a tumor , hemorrhage , or edema pushes the uncus over the tentorial notch against the brainstem ...
A pancreatic injury is some form of trauma sustained by the pancreas. The injury can be sustained through either blunt forces, such as a motor vehicle accident, or penetrative forces, such as that of a gunshot wound. [1] The pancreas is one of the least commonly injured organs in abdominal trauma. [2]
The pancreas is an organ of the digestive system and endocrine system of vertebrates. In humans, it is located in the abdomen behind the stomach and functions as a gland. The pancreas is a mixed or heterocrine gland, i.e., it has both an endocrine and a digestive exocrine function. [2] 99% of the pancreas is exocrine and 1% is endocrine.
The pancreas is a large organ behind the stomach that produces digestive enzymes and a number of hormones. [1] There are two main types: acute pancreatitis, and chronic pancreatitis. [1] Signs and symptoms of pancreatitis include pain in the upper abdomen, nausea and vomiting. [1] The pain often goes into the back and is usually severe. [1]
Both the left and right hemispheres of the brain have a lateral geniculate nucleus, named after its resemblance to a bent knee (genu is Latin for "knee"). In humans as well as in many other primates, the LGN has layers of magnocellular cells and parvocellular cells that are interleaved with layers of koniocellular cells.
The ventral pancreas develops at the junction of the hepatic duct and the rest of the foregut. During development, differential growth of the wall of the stomach causes it to rotate to the left, and the liver and stomach undergo a lot of growth. This makes the two parts of the pancreas rotate around the duodenum.
The genu is the bend, or flexure in the V of the internal capsule. It is formed by fibers from the corticobulbar tract . The fibers in this region are named the geniculate fibers that carry upper motor neurons from the motor cortex to cranial nerve nuclei that mainly govern muscle motion of the head and face.
Visceral pain should be suspected when vague midline sensations of malaise are reported by a patient. True visceral pain is characterized as a vague, diffuse, and poorly defined sensation. [9] [10] Regardless of specific organ of origin, the pain is usually perceived in the midline spanning anywhere from the lower abdomen up to the chest. In ...
