Neurulation is the formation of the neural tube from ectodermal cells during embryonic development. The neural tube later develops into the individual structures of the central nervous system. In neurulation disorders, the formation of the neural tube is defective, which can result in various malformations of the nervous system. What is neurulation? Neurulation, in the … Neurulation: Function, Tasks, Role & Diseases
Omega-6 fatty acids belong to the group of unsaturated fatty acids. They are essential for the body, which means that they must be supplied with food. What are omega-6 fatty acids? Omega-6 fatty acids are polyunsaturated fatty acids. The most important omega-6 fatty acids are linoleic acid (LA), gamma-linolenic acid (GLA), dihomo-gamma-linolenic acid (DHGLA), and … Omega-6 Fatty Acids: Function & Diseases
Fibrocytes are part of the connective tissue. They are normally in a resting state and have irregular projections that join with the projections of other fibrocytes to give connective tissue three-dimensional strength. When needed, such as after mechanical injury, fibrocytes can “awaken” from their dormancy and revert to fibroblasts by dividing to synthesize components of … Fibrocyte: Structure, Function & Diseases
Most people develop a daily routine of personal hygiene throughout their lives. This process usually begins in childhood and is copied and internalized by parents and other adults. Personal hygiene serves primarily an end in itself, but it also has to do with the social environment. Thus, it equally fulfills various functions, and various types … Personal Hygiene (Body Care): Function, Tasks, Role & Diseases
The peristaltic reflex is a movement reflex in the intestine. The reflex is triggered by pressure on mechanoreceptors located in the intestine. The nervous system of the intestine is relatively autonomous, so the reflex can still be observed in an isolated intestine. In diseases such as diabetes, the reflex may cease. What is the peristaltic … Peristaltic Reflex: Function, Tasks, Role & Diseases
The human body has billions of cells. These are small building blocks responsible for maintaining and building tissues and organs. In order for cells to maintain, divide or destroy themselves, a cell cycle takes place. The cell cycle in the organism consists of cell growth and division. Cell growth concerns the increase in size and … Cell Growth: Function, Tasks, Role & Diseases
Cell metabolism is the basis of all vital and biochemical processes in the body that take place inside and also outside a cell. Everything the body takes in must be processed and transformed, eventually broken down, to be used for energy and to renew and build up the various body components such as cell walls, … Cell Metabolism: Function, Tasks, Role & Diseases
The cellular memory hypothesis assumes information storage at the molecular genetic and cellular levels. The best-known example of cellular memory is with the antigen memory of the immune system. Meanwhile, the BMI1 protein of cellular memory is associated with carcinogenesis. What is cellular memory? The cellular memory hypothesis assumes information storage at the molecular genetic … Cellular Memory: Function, Tasks, Role & Diseases
The radius periosteal reflex is an intrinsic reflex of the human body. Normally, a blow to the arm triggers a slight flexion of the forearm; if the reflex is absent, this may indicate a neurological or muscular disorder. What is the radial periosteal reflex? The radius periosteal reflex is an intrinsic reflex of the human … Radial Periosteal Reflex: Function, Role & Diseases
The pulmonary artery is an artery that carries deoxygenated blood from the heart to one of the two lungs. The two arteriae pulmonales are branches of the truncus pulmonalis, the pulmonary trunk that connects to the right ventricle of the heart. Sensuously, the two pulmonary arteries are referred to as the sinistra pulmonary artery for … Pulmonary Artery: Structure, Function & Diseases
The radial artery, together with the ulnar artery, forms the continuation of the brachial artery, which branches into the above two arteries via a bifurcation in the crook of the arm. On its way to the thumb and further fingers, it passes along the radius and forms a series of secondary branches on the forearm, … Radial Artery: Structure, Function & Diseases
A discus articularis is a joint disc. It is made of cartilage and connective tissue. In the human organism, there are several articular discs in different locations. What is the articular disc? In the human organism, there is a discus articularis in different places. It is an intermediate joint disc. This means that each discus … Discus Articularis: Structure, Function & Diseases
