Anatomy

Together with the back and chest muscles, the abdominal muscles form the muscular corset of the trunk. They enable various trunk movements, support breathing, protect the organs in the abdominal cavity and also work via the abdominal press

The navel is a rounded depression that remains on the front of the abdomen after the umbilical cord has been severed. In humans, the navel can appear in different manifestations. Simultaneously

The abdominal wall consists of three layers, which are composed of different types of tissue, and delimits the abdominal cavity with the abdominal organs. Damage in the tissue of the abdominal wall or a weakening of the associated muscles lead to various

The muscular pelvic floor made of connective tissue is located on the floor of the pelvic cavity. The pelvic floor is known for the pelvic floor weakness that often occurs in women.

The word leg can describe two things: In the old language every bone was a "leg" (as in "bones"), but today the term is actually only used to describe the lower extremity of the human body. The following is intended

The synaptic gap represents the gap between two nerve cells in the context of a chemical synapse.

The human mesolimbic system is called the positive reward center. It is part of the central nervous system. It is located in the cerebrum of the human organism.

The pelvis is an important part of the human skeleton. Ideally, it ensures an upright posture and a secure stance for people. This construction can be damaged from birth or in the course of a person's life

The musculoskeletal system comprises a complex organ system of the body, which not only enables the physical shape to be secured, but also supports posture and, last but not least, physical movement and locomotion. Together with the supporting apparatus

The spermatic cord is a bundle of nerves and vessels including the spermatic duct, which runs through the inguinal canal from the abdomen to the testicles. It is not a uniform body organ, but a supply system for those attached to it

The cremaster muscle is also known as the cremaster muscle or testicle lifter and surrounds the spermatic cord and testicles. It reflexively contracts to external stimuli such as cold and pulls the testicles towards the trunk. With testicular deficiencies such as the pendulum testicle

The sweat glands are located in the skin and ensure that sweat formed there is excreted through the same. Their job is to regulate the body's heat balance. So-called scent glands can be found in some areas of the body

The vagus nerve is the tenth of a total of twelve cranial nerves, the nuclei of which are located directly in the brain. The vagus nerve makes up the largest part of the parasymphaticus and is connected to almost all internal organs via multiple branches. Besides his

The two thyroid hormones T3 (also triiodothyronine) and L4 (also L-thyroxine or levothyroxine) are produced in the epithelial cells of the thyroid gland. Their control is subject to the regulating hormone TSH basal (thyroid-stimulating hormone or thyrotropin)

Air sacs (alveoli) are important components of the lungs. They are responsible for the exchange of gases between the blood and the outside world. The alveoli ensure the intake of fresh air and the removal of the air generated by breathing

The back muscles support the entire body so that a person can stand upright and provide the necessary stability. Well-trained back muscles are important for performance and resilience because they enable movement

As the proverbial backbone, the spine gives the body shape and stability. Their specific shape enables people to walk upright.

The sinuses are air-filled cavities within the bone structure of the skull. The most common complaint is sinusitis, which is associated with pain and runny nose, but usually subsides after 10 days.

Chromosomes are the carriers of genetic information. They ensure that the parents' physical characteristics are passed on to their children. At the same time, serious illnesses can arise

The milk teeth develop in the first year of life. During the growth process, the deciduous teeth are gradually replaced by the permanent ones.
