Anatomy

The sternohyoid muscle is a muscle that belongs to the human skeletal muscles. Its path is from the chin down to the sternum. It belongs to the hyoid muscles.

Veins are essential for one of the most important organs in the human body: the heart is constantly supplied by the blood that the veins (also called blood vessels) carry to the organ. The veins of the body are all connected to the heart, so too

The atlas is the first cervical vertebra to carry the skull. It forms an articulated connection with the parietal bone.Fractures in the area of ​​the atlas ring can destroy the medulla oblongata and cause death to occur.

The sternothyroid muscle is a muscle of the human skeletal system. It is located between the tongue and the larynx. Its task is to support the swallowing process.

The internal occipital protuberance is a part of the skull of the human body. It is assigned to the occiput. The internal occipital protuberance is a protruding bone.

The posterior cranial fossa forms the posterior fossa. It contains the elongated medulla (medulla oblongata), the bridge (pons), the midbrain (mesencephalon) and the cerebellum (cerebellum).

The sigmoid sulcus is a groove in the bone of the skull. It is located in the back of the skull. It is formed by the sigmoid sinus.

Skeletal muscles are particularly important for the human body because they allow it to move freely.

The upper head joint is called the atlanto-occipital joint. Together with the lower head joint, it enables mobility that is similar to that of a ball joint.

The triceps is what is known as the triceps brachii muscle, a muscle on the back of the upper arm. This muscle can stretch the forearm in the elbow joint. Both overload and inactivity can lead to complaints

The photoreceptors of the retina responsible for light-sensitive monochromatic night vision and for peripheral vision are called rods. The main concentration of the rods is outside the central area of ​​the retina

The photoreceptors on the retina of the eye responsible for color and sharp vision are called cones. They are strongly concentrated in the yellow spot, the area of ​​colored and at the same time sharpest vision. Man has

The capillary is the finest human blood vessel. It is essential for the supply of nutrients and oxygen to the organs and an important part of the bloodstream.

The lower legs of humans are not only important tools for the human gait, they are often also an optical feature: they can be tight or hairy, they are tanned or have varicose veins. All of this often has to do with the

The pulmonary valve regulates the flow of blood from the heart to the lungs. Illnesses can significantly impair performance.

The umbilical cord connects mother and child in the womb during pregnancy. The fetus is connected to the mother's bloodstream via the placenta. After birth, it loses its meaning.

Microtubules are protein filaments that have a tubular structure and, together with the actin and intermediate filaments, form the cytoskeleton of eukaryotic cells. They stabilize the cell and also affect the transports and movements within

Myelin is a special, particularly lipid-rich, biomembrane which, as the so-called myelin sheath or myelin sheath, encloses axons of the nerve cells of the peripheral nervous system and the central nervous system and the nerve fibers it contains

The pylorus (stomach gatekeeper) represents the transition between the stomach outlet and the duodenum. It is responsible for the fact that the stomach contents only enter the small intestine and do not return from there in the homogenized state. The vast majority

The motor or neuromuscular endplate is the contact point between a motor neuron and a muscle cell. It is also known as a neuromuscular synapse and is used to transmit excitation between a motor nerve fiber and a
