The adrenals are a paired organ that sits on the upper pole of both kidneys. It is a hormone gland divided into two parts - the adrenal medulla and the adrenal cortex. They produce different hormones like the stress hormone epinephrine (in the pith). Read here everything important about the adrenals: Function, anatomy and important diseases!
The aorta or main artery is the central vessel in the bloodstream. The heart pumps blood from the left ventricle directly into this thickest of all vessels. Five liters per minute flows through it in peace with an adult. Read all important information about the aorta here! Article overview Aorta The central vessel Aortic section Aortic architecture The role of the aorta Main artery Diseases The central vessel In the adult, the aorta is about 35 to 40 centimeters long and, with a diameter of about three centimeters, the thickest vessel in the body.
An artery is a blood vessel that sends blood from the heart into the body. Arteries, unlike veins, have a pronounced muscle layer in their walls. In them, the pulsation of the heartbeat is noticeable, which is why they are also called punch or pulsatile arteries. Read all important information about the arteries here!
The dermis (corium) is the rough dermis, which consists of tight connective tissue. It lies as an intermediate layer under the epidermis (epidermis) and above the subcutis (subcutis). The dermis contains the sebaceous and sweat glands, hair follicles, vessels and nerves as well as muscle cells. Read all about the dermis!
The duodenum is the first section of the small intestine. It begins at the exit of the stomach (pylorus) and, after about 25 to 30 centimeters, passes into the jejunum, the second small intestine section. The duodenum performs important digestive work and provides hormones and other messengers.
The epididymis (epididymis, parorchis) belong to the male sex organs and lie on the back surface of the testicle. They are the maturation site for the sperm cells that are formed in the testicles. In addition, the sperm are stored in the epididymis until the next ejaculation. Read all important information about the epididymis: function, anatomy and important diseases!
Epiglottis is the medical term for the epiglottis or laryngeal sail - a part of the laryngeal skeleton of all mammals, including humans. The epiglottis is located above the trachea and closes it during swallowing, so that no porridge can enter the trachea.
The Eustachian tube (Eustachian tube, tuba auditiva) is the connection between the middle ear and the nose and throat area. Through this connection, the pressure balance between the tympanic cavity and the outside air takes place. Particularly important is this possibility of pressure equalization in diving, flying and cable car driving.
The ileum is the last part of the small intestine after the jejunum (jejunum). With a length of about three meters, it accounts for three-fifths of the entire small intestine. In the ileum - as in the rest of the small intestine - digestive processes take place and also the absorption of water and bile acids. Read all about the ileum!
The jejunum (jejunum) is the middle section of the small intestine between duodenum (duodenum) and ileum (ileum). It accounts for about two-thirds of the length of the entire small intestine. In the jejunum, nutrients and water are absorbed from the porridge. The rest is transported further to the ileum.
The pleasure-drop is a clear, tough secretion that comes out of the penis when the man is sexually aroused. This pre-ejaculate is used to prepare the urethra for ejaculation (ejaculation) by creating a sperm-friendly environment. In addition, the pleasure drop acts as a natural lubricant.
The nephron is the basic functional unit of the kidney. Here the urine is formed, which is then excreted. Each kidney contains approximately 1 to 1.4 million nephrons. Each consists of a kidney body (Corpusculum renale, Malpighi body) and the associated renal tubules (Tubulusapparat).
The ossicles are three tiny bones in the ear, called the hammer, anvil and stirrup. They are located in the tympanic cavity in the middle ear and are hinged together. So they form the so-called ossicular chain through which the sound from the eardrum is passed over the middle ear to the inner ear.
The penis (limb, phallus) represents - together with the scrotum - the external male reproductive organ. The semen (semen) formed in the testicle and matured in the epididymis (sperm) reach the ejaculation through the penis to the outside.

The sacroiliac joint (ISG) or sacral iliac joint connects the lower spine to the pelvis. This connection is held by tight ligaments and is very little mobile, but can be postponed by bad postures or injuries. Even minimal shifts can lead to pain.
