The pectoralis major muscle (large chest muscle) arises near the breastbone on the chest and attaches to the upper arm. Its functions are the adduction of the arm from the raised position, the internal rotation of the arm and the anteversion.
The tibialis posterior tendon connects the posterior tibialis muscle on the lower leg with the bone attachments under the foot. In the event of severe irritation or sudden heavy stress, the tendon can become inflamed or tear.
The peroneal or fibular tendons are the end segments of the muscle group of the same name and are primarily used for plantar flexion and pronation. A tear in one or both peroneal tendons is rare; it can occur as part of a twisting event
The "Adam's apple" refers to the protruding and palpable section on the larynx, in the middle part of the neck. The thyroid cartilage is more pronounced and easier to see in men than in women. The larynx separates the airways from the food passages and
The soft palate (Latin: Velum palatinum) is a flexible and soft continuation of the hard palate. This continuation appears as a soft tissue fold and consists of connective tissue, muscles and mucous membrane. Often times it will be because of its composition
The lungs are supplied by two functionally different vessels: the vasa privata on the one hand, which ensure the blood supply to the lungs themselves, and the vasa publica, on the other hand, which enrich the blood with oxygen through the lungs and
The diaphragm is arterially supplied by two upper and two lower diaphragmatic arteries (Arteriae phrenicae superiores / inferiores), the cardiac diaphragmatic artery (Arteria pericardiacophrenica) and the diaphragmatic muscle artery (Arteria musculophrenica), the
The palatine arch is the folds of the mucous membrane raised by the soft palate (velum palatinum). A distinction is made between an anterior and a posterior palatal arch. When the mouth is open, the two palatal arches are clearly visible. A function of the palate
The heart is a vital organ that powers blood flow by pumping all oxygen-rich blood around the body to supply all organs and tissues. It also transports oxygen-poor blood into the pulmonary circulation
The aortic root is a small section of our main artery (aorta) that is only a few centimeters long. This part of the aorta begins in the left ventricle and extends a few centimeters vertically upwards until it reaches the aortic arch m

The tasks of the stomach include the chopping, mixing and storage of the food supplied. In addition, there is an extremely acidic environment in the stomach, which kills pathogens and ensures that the food is pre-digested. So he's preparing
The hormones found in the pancreas include insulin, glucagon and somatostatin. The hormones in the pancreas mainly affect the metabolism of carbohydrates. Furthermore, they participate in the regulation of protein and fat metabolism
The small intestine essentially takes on the task of breaking down our food into its components and absorbing them. The numerous folds in the intestinal lining create so much space for absorbing nutrients. Hence the mucous membrane
The pancreas is divided into two functional parts. One is responsible for regulating blood sugar levels with its hormones insulin and glucagon. The second produces the digestive juice, which contains many enzymes and in
The pancreas can be divided into two parts both microscopically and functionally. The exogenous part is used for the production of digestive enzymes. The endogenous part produces, among other things, hormones that regulate blood sugar levels
The inflammation of the spleen can be caused by various causes. The most common cause is a systemic infectious disease.
