The Wallenberg syndrome is a rare condition in which the infarction or stroke occurs in the lateral cortex. The lateral core is part of the brainstem. Oxidized blood does not reach the part of the brain when the arteries that lead to it are blocked. Due to this blockage, a stroke may occu

The eyes are the organs of the visual system. They provide visions to the bodies, the ability to receive and process visual details, and also enable several photo response functions that are independent of the vision. The eyes detect light and transform it into electrochemical impulses in

The Bulbourethral gland, also known as the Cowper gland for the English anatomy of William Cowper, is one of the two small exocrine glands in the reproductive system of many male mammals (all domesticated animals that are not only found in a dog). They are homologous to Bartholin's glands in women.   read more

The snail is the most critical element of the inner ear. It is divided into three chambers filled with liquid, called scale, that move spirally around the bone core. In the medium merges, i.e. in the cochlea channel, there is the organ of Corti, who receives the sound. The Corti organ con

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

(Chicken virus) A study by a food regulatory authority showed that seven out of ten hens sold in British supermarkets are contaminated with a dangerous bacterium that causes food poisoning. Every year, 280,000 people get sick and kill 100 people. Chic

The sinus node (SA node), also known as the sinus node, 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 t

Cerebrospinal fluid is a clear, colorless transcellular fluid, in the ventricular system, and the central canal of the spinal cord. It also fills some gaps in subarachnoid space, known as subarachnoid cisterns.  The four ventricles, four lateral, a third, and a fourth ventricle, all cont

Muscles play a role in every function of the body. The muscular system consists of over 600 muscles. These include three types of muscles: smooth, skeletal and cardiac. Only skeletal muscles are voluntary, which means that you can control them consciou

 Many critical discoveries have underlined the importance of astrocytes in establishing a synaptic connection in the developing brain. In this article, we review the key findings of astrocytes function and elimination of synapses. First, we summarize our current structural and functional

You will want to take care of what you are feeding your Chihuahua. This breed is very sensitive to what they are fed, how often they eat and how dishes are offered to them. In fact, the food you choose for your Chihuahua for both meals and snacks will have a direct impact on your puppy's

A fibroblast is a type of biological cell that synthesizes the extracellular matrix and collagen, produces the structural framework (stroma) for animal tissues and plays a fundamental role in the healing of wounds. Fibroblast function is the most common connective tissue cells in animals.

In biology, cytoplasmic cells are a material in a living cell, excluding the cell nucleus. It contains cytosol (a gel-like substance encapsulated in the cell membrane) and organelles - internal cell substructures. The entire content of the cells of prokaryotic organisms (such as bacteria

what is metabolism and how does it work?  The brain uses up to 20% of the energy consumed by the human body, more than any other organ.  In humans, blood glucose is the main source of energy for most cells and is critical to normal function in many t

Synapse neuron is basically electrical devices. There are many channels in the cell membrane (the boundary between the cell inside and outside) that allow the flow of positive or negative ions into and out of the cell. Usually, the inside of the cell i

The brain arteriovenous malformation (AVM brain) is a tangle of abnormal blood vessels that connect the arteries and veins in the brain. Arteries are responsible for getting oxygen-rich blood from the heart to the brain. The veins carry oxygen-free blood back to the lungs and heart. The A

There is no difference in the incidence and prevalence of schizophrenia between men and women, although schizophrenia is more strongly associated with younger men. This may be due to the fact that women more often than men experience the beginning of schizophrenia. Schizophrenia symptoms

The medulla oblongata is in the brainstem, before (before) the cerebellum. It is a conical, neuronal (nerve cell) mass in the back brain that controls many autonomic (involuntary) functions. The main medulla oblongata function of the hill is the proce

The coronary sinus is a collection of veins connected together to form a large vessel that collects blood from the myocardium (myocardium). It provides less oxygenated blood to the right atrium, as well as better and weaker veins. It occurs in all mammals, including humans.

Pneumothorax (noo-moe-THOR-aks) is a collapsed lung. Pneumothorax occurs when the air leaks into the space between the lung and the chest wall. This air pushes the outside of the lungs and causes it to collapse. In most cases, only part of the lungs collapses. read more
