The spleen is located in the upper left abdomen. Their main function is to sort out erythrocytes (red blood cells) that are too old by migrating them through a close-knit network through which only new, flexible cells come. But it is also part of the
The pancreas produces a variety of enzymes for the digestion of carbohydrates, proteins and fats.
Trypsinogen is a precursor of the enzyme trypsin, which is released from the pancreas into the small intestine in order to break down food components - more precisely the amino acids - into small pieces. Only then can the body absorb them
The Douglas space is the deepest part of the female abdominal cavity. It is bounded at the front by the uterus and at the back by the rectum and is completely lined with peritoneum. Due to its deep location, free fluids collect here
The luteinizing hormone, LH (translated as "yellow coloring hormone"), affects the gonads in humans and fulfills important functions for the ability to reproduce (so-called fertility). In women it is indispensable for ovulation and during
The function of the individual kidney components are very far-reaching. The most important tasks include the regulation of the electrolyte and water balance as well as the acid-base balance, the elimination of waste materials, hormone production and control
The sebum glands on the labia produce a protective layer and moisturize the skin. However, the ducts of the sebum glands can become blocked, causing them to become inflamed and cause unpleasant symptoms.
The posterior lobe hypophysis hormones include oxytocin and antidiuretic hormone (ADH). ADH acts on the blood vessels, via the kidneys on the water balance and on the anterior pituitary gland. Oxytocin is known as the "cuddle hormone", but it also has a function
The blind spot is the area in the field of vision of each eye where there are no sensory cells that can receive light. This is where the optic nerve exits through the retina. The position and effects of the blind spot can be easily identified by anyone
The tear system is a complex system made up of many small units, which ensure the production and removal of tear fluid.
The auricle is part of the outer ear and, together with the auditory canal, represents the sound conduction apparatus. The auricle has a funnel shape that enables it to better capture sounds. Outer ear infections are common diseases
When choosing a partner, the other person's smell plays a decisive role. Cosmetics manufacturers take advantage of this by adding mochus, a fragrance from the animal world, to most perfumes. Man-made ones go one step further
A Ranvier ring is created by interrupting the myelin sheaths on nerve fibers and is used to increase the speed of nerve conduction. Here the action potentials "jump" from one Ranvier ring to the next, which is called saltatory
Each cell is surrounded by a cell membrane, a barrier that consists of a special double layer of fat particles, the so-called lipid double layer.
A synapse is the place where the signal transmission from a nerve cell to its target cell takes place. When the electrical signal arrives at the synapse, the information is transmitted via messenger substances into the synaptic cleft and absorbed by the target cell. Poisons
Cell plasma or cytoplasm is understood to mean the entire content of the cell with the exception of the cell organelles. The cytoplasm is an organic liquid that consists of proteins as well as water. It is used for nutrient transport, communication in
A ganglion is a collection of cell bodies from different nerve cells. It mainly serves as a switching station and is presented in the form of a thickening of the nerve cord. Even small pieces of information can be processed close to the organs. At
The axon hill is the place in the nerve cell where the inhibitory and excitatory signals that reach the cell via dendrites are offset. The summed signal is then passed on via the axon originating on the axon hill.
A neurite is responsible for the transmission of electrical impulses in a nerve cell. The cell process is often isolated by what is known as a myelin sheath, which enables rapid transmission. If this insulation breaks
Denervation is the complete or partial interruption of nerve pathways between an organ and the brain. Denervation can be used either specifically to combat chronic pain, for example, or as undesirable
