The term diverticulitis represents a spectrum of inflammatory changes that ranges from localized subclinical inflammation to generalized peritonitis, with free perforation (Answers.com). In turn, this leads to hyperplasia of the lymphoid tissue within the mucosa at the base of the diverticulum, one of the earliest signs of diverticulitis. Inflammation usually begins at the apex of the diverticulum and seldom involves the neck or mucosa proximal to the neck. However, there is active inflammation of the pericolic and mesenteric fat, with peridiverticular abscess formation. These peridiverticular abscesses often involve areas of subserosa and are closely related to the outer aspect of the muscularis propria; they can spread circumferentially and longitudinally and may be responsible for the pathologic picture of diverticular colitis. Longitudinal tracking, especially, may result in fissuring, along with the lymphoid aggregates, which resembles the distinctive feature of colonic colitis in Crohn's disease. Answers.comThis may cause misinterpretation of the pathologic study of the specimen. Therefore, the differential diagnosis of these two conditions in terms of pathologic interpretation of the resected specimen is important. Persistent localized inflammation after diverticular rupture results in a phlegmon, a thickened, firm segment of bowel wall, which ultimately may manifest as acute or subacute large bowel obstruction. If left untreated or treated inadequately, it may result in extensive fibrosis around the affected segment of the colon, giving it a mass appearance indistinguishable macroscopically from that of a neoplasm.
Another pathologic entity that may be encountered during progression of the disease, with recurrent attacks of diverticulitis, is the formation of a localized abscess with chronic inflammation and involvement of other neighboring luminal organs, such as the bladder, small and large bowel loops, uterus, and vagina. Fistulae may develop within this contained area, between involved segment(s) of colon and these organs. Fistulae occur in 2.4% to 20% of cases; 65% of these fistulae are colovesical and 20% are colovaginal fistulae. Answers.com
Reabsorption is the process by which molecules move from the proximal convoluted tubule into the blood.
The parts of the proximal tubule in the nephron are the proximal convoluted tubule (PCT) and the proximal straight tubule (PST). The PCT is the first segment after the Bowman's capsule and is responsible for reabsorbing nutrients, ions, and water. The PST continues the reabsorption process and plays a role in maintaining the body's fluid and electrolyte balance.
Increased capillary permeability
The superior articular process of the sacrum articulates with the inferior articular process of the last lumbar vertebra (L5) to form the lumbosacral joint.
Yes, the proximal convoluted tubule is the site of reabsorption of glucose and amino acids from the filtrate back into the bloodstream. This process helps to maintain the body's overall balance of these important nutrients.
Breathing is not an inflammatory process. An inflammatory process is where the body's immunity system through the white blood cells will respond to a particular injury.
Yes, lupus is an inflammatory disease.
No, the acromial region is more proximal and superior to the olecranon. The acromial region refers to the part of the shoulder formed by the acromion process of the scapula, while the olecranon is the bony tip of the elbow.
Prolonged inflammation, healing of the tissue from the inflammatory process
Reabsorption is the process by which molecules move from the proximal convoluted tubule into the blood.
The triceps originates on the scapula and proximal humerus and inserts on the olecranon process. The muscles has three heads (hence its name) so it has multiple origins.
Describe the major steps in the inflammatory process.

The proximal attachment of the anconeus muscle is the lateral epicondyle of the humerus, while the distal attachment is the olecranon process of the ulna. The anconeus muscle plays a role in assisting the triceps brachii muscle in extending the forearm at the elbow joint.

The ulna has the head at the distal end. Usually the head of a bone is located at the proximal end. The ulna has a large process called the olecranon process that people call their 'elbow'.
There is no inferior process on any vertebrae, thoracic or not. There is an inferior articular facet. The inferior articular facet would articulate with the superior articular facet of the vertebrae just superior to it.
