Late development of peritoneal cavity

Ravnik Dean

The third phase of the peritoneal cavity development with fusions of peritoneal  layers is described. The fixation and relations among abdominal organs are presented and compared with the first two phases of the development.… Preberite več >>

Histology, Anatomy and Functional Organisation of the Central Nervous System Cortex

Meh Duška

The cerebral cortex represents a relatively small part of the central nervous system. It contains a prodigious number of cells that lead our behaviour. In a general way, the central sulcus divides the cerebral cortex into a cerebral receptive portion and an anterior part related to motor function. Association areas interconnect cortical regions. Different cortices differ in arrangement, type and … Preberite več >>

Early development of peritoneal cavity

Ravnik Dean

Two early phases of peritoneal cavity  development are described: the primitive midline arrangement and shifts of viscera with their mesenteries. The importance of these phases for the abdominal situs is presented.… Preberite več >>

Embryology of the Nervous System

Petrovič Danijel

The notochord and para-axial mesoderm induce the overlying ectoderm to differentiate into the neural plate. Formation of the neural tube begins in the fourth week, when the walls of the neural tube thicken to form the brain and spinal cord. The neural canal is converted into the ventricular system of the brain and the central canal of the spinal cord.

The Development of the Urinary Tract

Petrovič Danijel

The intermediate mesoderm gives rise to the kidney. Three pairs of kidney make an appearance in succession during development: pronephros, mesonephros and metanephros or permanent kidneys. Permanent kidneys develop from metanephric diverticulum (ureteric bud) and metanephric blastema. The ureteric bud gives rise to the ureter, renal pelvis, major and minor calyces, and approximately one to three million collecting tubules, whereas … Preberite več >>

Human Telomere and Telomerase: Structure, Function and Role in Cancerogenesis

Luzar Boštjan, Gale Nina, Poljak mario, et al.

With each somatic cell division, the chromosomal ends, or telomeres, progressively shorten. Critically shortened telomeres are recognised by DNA repair systems as DNA damage, the cells are withdrawn from the cell cycle, senesce and eventually die. Mutations in the genes responsible for cell division cycle control, or repression of their protein products, enable cells to continue their proliferation. In the

Histological changes of breast in relation to the menstrual cycle and the age of woman

Cör Andrej

In the breast biopsy analysis we are frequently encounter with normal histological pictures of the breast tissue. Breast tissue has wide spectrum of »normal histology« in relation to phase of menstrual cycle and the age of woman. For the purpose to help students to study breast histology and embryology, the author described the embryology of mammary gland as well as … Preberite več >>

Normal Development and Abnormalities in the Development of Human Embryo

Petrovič Danijel

Human embryology is the science dealing with the development of the embryo and fetus from fertilization to birth. Development begins with fertilization, the process by which the male gamete, the sperm, and the female gamete, the oocyte, unite to give rise to a zygote. The zygote undergoes a series of mitotic divisions, increasing the number of cells; a 16-to-32-cell morula

Vasa Vasorum and Atherosclerosis of Coronary Arteries

Hojs Nina, Hrovat Eva

Vasa vasorum (»vessels of the vessel«) are arterioles, capillaries and venules that nourish large arteries and veins. They are derived either from the main blood vessel itself in the case of arteries, and for veins from adjacent arteries as venous vasa vasorum. Atherosclerosis is a systemic dysfunctional endothelial, chronic inflammatory, fibro-proliferative, prothrombotic, angiogenic, multifactorial disease of the arterial intima caused

Development of Branchial Organs

Petrovič Danijel

The branchial or pharyngeal apparatus is the region extending from the oropharyngeal (buccopharyngeal) membrane to the trachea. This apparatus consists of the branchial (pharyngeal) arches, the pharyngeal pouches, the branchial (pharyngeal) grooves and the branchial membranes. In the 4th and 5th week of the development of the embryo five pharyngeal pouches, four branchial grooves and five branchial arches are seen … Preberite več >>
