As part of the os sphenoidale, the sella turcica forms a bony structure at the base of the skull. Within the saddle-shaped depression sits the pituitary gland, which is connected to the thalamus via the pituitary stalk. Hormonal processes in the human body are controlled from here. What is the sella turcica? The term “sella … Sella Turcica: Structure, Function & Diseases
In gene therapy, genes are inserted into a human genome for the treatment of hereditary diseases. Gene therapy is generally used for distinct diseases, such as SCID or septic granulomatosis, that cannot be controlled by conventional therapeutic approaches. What is gene therapy? Gene therapy involves inserting genes into a human genome to treat inherited diseases. … Gene Therapy: Treatment, Effects & Risks
Introduction The erythrocytes (red blood cells) are flat, nucleusless discs with a size of about 8 micrometers and are the main representatives in the blood of vertebrates. Their biconcave shape (wider at the edges than in the center) and size allow optimal flow properties in narrow capillaries. Inside the dented center is the red blood … Erythrocytes
Diseases Possible diseases on the basis of erythrocytes Anaemia: The number of red blood cells is reduced, mostly due to iron deficiency. Polyglobulia: Here the number of red blood cells is increased. The result is thick blood and an increased risk of thrombosis. Hemolysis: This is the increased breakdown of red blood cells and leads … Diseases | Erythrocytes
Tetrahydrofolic acid plays an important role in the transfer of carbon as coenzyme F in the organism. It is synthesized from folic acid (vitamin B9). Deficiency of THF triggers, among other things, macrocytic anemia, the form triggered by vitamin B12 deficiency being called pernicious anemia. What is tetrahydrofolic acid? Tetrahydrofolic acid functions as an important … Tetrahydrofolic Acid: Function & Diseases
The endoplasmic reticulum (ER) is present in every eukaryotic cell except mature erythrocytes. It is a cell organelle with multiple functions. Without ER, the cell and thus the organism would not be viable. What is the endoplasmic reticulum? The endoplasmic reticulum (ER) is a very structurally rich cell organelle with a channel system of cavities. … Endoplasmic Reticulum: Structure, Function & Diseases
Acute lymphoblastic leukemia, or ALL, is an acute form of leukemia caused by malignant lymphocyte precursor cells. It mostly affects children. The cure rate is approximately 50% in adults and 80% in children. What is acute lymphoblastic leukemia? Acute lymphoblastic leukemia, or ALL, is an acute form of leukemia caused by malignant lymphocyte precursor cells. … Acute Lymphoblastic Leukemia: Causes, Symptoms & Treatment
The term hypermenorrhea refers to excessively heavy menstruation. In this, there is a significant increase in blood loss as well as additional shedding of tissue. The causes are changes in the reproductive organs or other mental and physical disorders. Depending on the individual reason for the symptoms, hypermenorrhea can be treated differently. What is hypermenorrhea? … Hypermenorrhea: Causes, Symptoms & Treatment
Protozoa are single-celled organisms. Protozoan infections can be very dangerous to humans. What are protozoa? Protozoa are a group of eukaryotic organisms. Eukaryotes, unlike prokaryotes, are living organisms that have a nucleus. Together with the fungi and the algae, the protozoa form the protist group. The protozoa are assigned to the animal kingdom, whereas algae … Protozoa: Infection, Transmission & Diseases
Glycolysis involves biocatalytically controlled breakdown of simple sugars such as D-glucose in humans and in almost all multicellular organisms. The degradation and conversion process of glucose to pyruvate occurs in ten sequential steps and can occur under aerobic and anaerobic conditions alike. Glycolysis is used for energy production, and pyruvate provides an initial precursor for … Glycolysis: Function, Tasks, Role & Diseases
Glycogen consists of glucose units and is a polysaccharide. In the human organism, it serves to provide and store glucose. The buildup of glycogen is called glycogen synthesis, and the breakdown is called glycogenolysis. What is glycogen? Glycogen is made up of something called glycogenin, a central protein to which thousands of glucose molecules are … Glycogen: Function & Diseases
Globular cell anemia is a genetic disorder with anemia as its leading symptom. The anemia is due to the decreased lifespan of red blood cells, which is caused by defects in the erythrocyte membrane. Therapy consists of removal of the spleen. What is spherocytosis? Hemolytic anemias are types of anemia in which the lifespan of … Globular Cell Anemia: Causes, Symptoms & Treatment
