The cat's stomach is a sac-like structure designed to store large volumes of food and continue the digestive process. The esophagus carries food to the stomach, where it enters via a valve-like structure called the cardiac sphincter. On the interior surface of the stomach is a series of folds called gastric folds. These folds function to help grind and digest food. The inner stomach lining secretes acids and enzymes to break down food. Once the initial stomach digestive process is complete, the partially digested food exits the stomach through the pyloric sphincter area and then enters the duodenum (first segment of the small intestine). Once eaten, most food leaves the stomach within twelve hours after entering.
Thymoma is a tumor originating from the epithelial cells of the thymus. Thymoma is an uncommon tumor, best known for its association with the neuromuscular disorder myasthenia gravis; thymoma is found in 20% of patients with myasthenia gravis. Once diagnosed, thymomas may be removed surgically.
A facet joint injection is a relatively simple, straightforward procedure, and is usually performed in an office based procedure suite or in an ambulatory surgical center. As with many spinal injections, facet joint injections are best performed using fluoroscopy (live X-ray) for guidance to properly target and place the needle (and to help avoid nerve injury or other injury).
S-ICD leaves the heart and vasculature untouched. It may be implanted using only anatomical landmarks, thereby eliminating the need for fluoroscopy during implant and therefore reducing radiation exposure for both patients and physicians and eliminating the need for lead apron during implant.
Although the Apgar score was developed in 1952 by an anesthesiologist named Virginia Apgar, you also might hear it referred to as an acronym for: Appearance, Pulse, Grimace, Activity, and Respiration. The Apgar test is usually given to a baby twice: once at 1 minute after birth, and again at 5 minutes after birth.
The pituitary gland is often portrayed as the "master gland" of the body. Such praise is justified in the sense that the anterior and posterior pituitary secrete a battery of hormones that collectively influence all cells and affect virtually all physiologic processes. The pituitary gland may be king, but the power behind the throne is clearly the hypothalamus. As alluded to in the last section, some of the neurons within the hypothalamus - neurosecretory neurons - secrete hormones that strictly control secretion of hormones from the anterior pituitary. The hypothalamic hormones are referred to as releasing hormones and inhibiting hormones, reflecting their influence on anterior pituitary hormones.
The average human digestive tract is home to as many as 1,000 species of microorganisms. Most of them are harmless -- or even helpful -- under normal circumstances. But when something upsets the balance of these organisms in your gut, otherwise harmless bacteria can grow out of control and make you sick. One of the worst offenders is a bacterium called Clostridium difficile(C. difficile, or C. diff). As the bacteria overgrow they release toxins that attack the lining of the intestines, causing a condition called Clostridium difficilecolitis.
Cerebral palsy refers to brain damage that occurs before a child is five years old. Therefore, adults cannot develop cerebral palsy. However, cerebral palsy does not get better or worse with age, so when a child has the condition, he or she will continue to have the condition into adulthood.
The cause of pectus excavatum is not known however it can run in families, with up to 25 percent of affected patients reporting chest wall abnormalities in other family members. Pectus excavatum occurs in approximately 1 out of 400–1000 children and is three to five times more common in males than females.
Fibrodysplasia ossificans progressiva (FOP) is a disorder in which muscle tissue and connective tissue such as tendons and ligaments are gradually replaced by bone (ossified), forming bone outside the skeleton (extra-skeletal or heterotopic bone) that constrains movement. This process generally becomes noticeable in early childhood, starting with the neck and shoulders and proceeding down the body and into the limbs. Extra-skeletal bone formation causes progressive loss of mobility as the joints become affected. Inability to fully open the mouth may cause difficulty in speaking and eating. Over time, people with this disorder may experience malnutrition due to their eating problems. They may also have breathing difficulties as a result of extra bone formation around the rib cage that restricts expansion of the lungs.
High-Cervical Nerves (C1 – C4) Most severe of the spinal cord injury levels Paralysis in arms, hands, trunk and legs Patient may not be able to breathe on his or her own, cough, or control bowel or bladder movements. Ability to speak is sometimes impaired or reduced. When all four limbs are affected, this is called tetraplegia or quadriplegia. Requires complete assistance with activities of daily living, such as eating, dressing, bathing, and getting in or out of bed May be able to use powered wheelchairs with special controls to move around on their own Will not be able to drive a car on their own Requires 24-hour-a-day personal care
The Distal Femoral Osteotomy System utilizes the same principles of design featured in the Tibial Osteotomy System. Specifically designed femoral osteotomy plates take into account the anatomical differences between the distal femur and proximal tibia.
