Anatomy

The entire digestive system breaks down food into simple substances in order to extract the usable substances for the organism. It practically consists of a long tube to which various digestive organs are tied.

The ankle is a functional unit of partial joints that enable mobility between the lower leg and the foot bones and the foot bones among themselves. Without them, an upright standing and wholeness is not possible.

Soft tissues include all soft tissues with the exception of epithelia, internal organs and glial tissue. Thus, fatty tissue, muscle tissue and connective tissue belong to the soft tissues.

The trochlear nerve is the fourth cranial nerve and motor innervates the superior oblique muscle. Together with the oculomotor nerve and the abducens nerve, it is involved in the movement of the eyeball. Double vision occurs when the nerve is paralyzed

The Musculus obliquus superior is a muscle of the external eye muscles, which is a skeletal muscle and is motor innervated by the fourth cranial nerve. The muscle is crucial for the downward look of the eyes and stands with

The neck repeatedly causes pain when turning the head and restricts mobility. As a rule, we then actually seem to have something in the form of stress "on our necks" - including tension, hardening, headaches and the like

The thigh bone is the longest tubular bone in the human skeleton and is also known as the femur in the medical field. Anatomically, it can be divided into several sections and plays a major role in locomotion. All the more drastic

The vocal folds are tissue structures in the larynx that contribute a large part to voice formation. The vocal folds and the glottis between them regulate both the volume and the pitch of the voice. Will the voice

The phrenic nerve is a mixed nerve that motor innervates the diaphragm. The nerve is involved in breathing. Complete paralysis of the structure is life threatening.

As a smooth inner skin, the endocardium covers the entire inner surface of the heart. All four heart valves also belong to the endocardium. Diseases of the inner lining of the heart and the heart valves often lead to heart failure.

The nasal bone (Latin: os nasale) is the largest bone in the human olfactory organ. It consists of a very thin pair of bones that run between the eyes and cover the nasal cavity. An injury to the nasal bone should always be examined by a doctor

Teeth have an important role to play. You have to chop up and chew the food we eat every day. To be able to do justice to this task, they have to be firmly anchored in the jaw.

For reproduction, nature has not only given humans the sperm and egg cells with the genetic information they contain. The male reproductive organs, which include the penis, are a basic requirement for consummation

The chin has a different shape in humans, it can be small or large, a dimple or a protruding or recessed shape. Although it does not form the center of the face, it does determine the entire face profile, which is why

Eyelids are skin wrinkles that lie above and below the eye and limit the eye socket towards the front. With them the eye can be closed. The main purpose of the eyelids is to protect and keep the eyes moist.

The autochthonous back muscles are the part of the back muscles that lie directly on the spine and ensure that the spine is straightened, rotated and tilted to the side as well as an upright posture of the head. The designation became autochthonous

The eye muscles serve the motor functions of the eyeballs, the accommodation of the lenses and the adaptation of the pupils. The 6 outer eye muscles are able to move the two eyeballs in the same direction and synchronously or to focus on a target

The ankle is a functional unit of partial joints that enable mobility between the lower leg and the foot bones and the foot bones among themselves. Without them, an upright standing and wholeness is not possible.

An axon is a special nerve process that transmits nerve impulses from a nerve cell to a target organ such as a gland or muscle or to another nerve cell. In addition, axons are able to use what is known as axonal mass transport

The axon hill represents the point of origin of the axon. This is where the action potential is formed, which is passed on via the axon to the presynaptic endbutton. The action potential is formed in the axon hill from the sum of individual more specific
