The smooth endoplasmic or smooth ER reticulum is an organelle that occurs both in animal cells and in plant cells. The organelle is a subunit in a cell that has a specialized function. The main function of a smooth ER is the production of cellular products such as hormones and lipids. It also distributes these […]
Electrical properties are one of the essential things that enable the heart to process. These electrical properties are accountable for the regulation of heart rate and rhythm. How the heart works step by step through the cycle of the heart The heart cycle covers many different things, enabling the heart to work. During […]
ganglion cells and their support cells contain the optic nerve. The optic nerve receives a visual signal in orbit and moves back and forth through the visual channel. Then it leads to fiber. At this point, the fibers from the temporal fields are broken up. The fibers then pass through optical paths. Most of the […]
left side pain above hip also calls pelvis. The lower part of the human body between the abdomen and thighs (sometimes also referred to as the pelvic area). The skeleton embedded in it (sometimes also referred to as the pelvis or pelvic skeleton). The pelvic torso includes the pelvis, cavity (space closed by the […]
paronychia is an infection of the skin around nails. Bacteria or a type of yeast called Candida usually cause this infection. Bacteria and yeasts can even combine into one infection. Depending on the cause of the infection, anemia may appear slowly and persist for weeks or appear suddenly and last for only one or two […]
Lymph is a fluid that flows through the lymphatic system, a system composed of lymphatic vessels (channels) and intervening lymph nodes, whose function, as the venous system, is the return of fluid from tissues to the central circulation. Interstitial fluid between cells in all body tissues enters the lymphatic capillaries. This lymph fluid is then […]
The pleura is a raw membrane that folds together to form a bilayer membranous pleural sac. The external pleura (pleural wall) is attached to the chest wall but is separated from the fascia by the endotoxin. The internal pleura (visceral pleura) includes the lungs and adjacent structures, including blood vessels, bronchi, and nerves. The pleural […]
arthritis in hands natural remedies (inflammation or more joints) is the main cause of hand pain. It can occur anywhere in the body but is especially common in the hands and wrist. There are over 100 different types of arthritis, but the most common are osteoarthritis and rheumatoid arthritis. Osteoarthritis usually affects older […]
Ribosomes are a cellular structure that produces a protein. The protein is needed for many cellular functions, such as repairing damage or managing chemical processes. Ribosomes can be found floating in the cytoplasm or attached to the endoplasmic reticulum. The location of ribosomes in the cell determines the type of protein produced. If the ribosomes […]
The myocardium is the thick, middle layer of the heart and is composed of cardiac muscle. Cardiac muscle is very unique because it possesses the characteristics of skeletal muscle and smooth muscle. Skeletal muscle controls. The muscles of the body. The myocardium acts on its own, with no conscious effort. Myocardium consists of thousands of […]
The SA node, also known as the sinus node. It is a group of cells located in the wall of the right atrium of the heart. These cells have the ability to spontaneously produce an electrical impulse (action potential, see below for more details) that travels through the heart via the electrical conduction system, causing […]
The cerebral cortex is connected to various subcortical structures, such as the thalamus and basal ganglia, by sending information to them via efferent connections and receiving information from them via afferent links. Most sensory information is directed to the cerebral cortex function through the hill. However, information on the sense of smell goes through […]
Inflammation of the hair follicles is a frequent condition of the skin in which inflammation of the hair follicle occurs. This is usually caused by a bacterial or fungal infection. In the beginning, it may look like small red protuberances or white pimples around the hair follicles – tiny pockets from which hair grows. The […]
Szyszynka is a small pea-shaped gland in the brain. Its function is not fully understood. Researchers know that it produces and regulates certain hormones, including melatonin. Melatonin is best known for its role in regulating sleep patterns. Sleep patterns are also called circadian rhythms. Learn more about pineal gland function. Szyszynka also plays a […]
Pia mater often referred to simply as pia, is a delicate inner layer of tires, membranes that surround the brain and spinal cord. Pia mater is a medieval Latin meaning “delicate mother.” The other two membrane membranes are the hard tire and the arachnoid. Both pia and spider veins are derivatives of the neural crest, […]
