White matter spinal cord
The white matter of the spinal cord consists of the predominantly myelinated ascending and descending nerve fibers. These are bundled as different strands (funiculi), in which they are each again in tractus or fasciculi with different
Spinobulbaris tract
The spinobulbaris tract is divided into the gracilis fasciculus and cuneatus fasciculus These two tracts lie in the posterior cord of the white matter of the spinal cord (funiculus posterior). They lead as an ascending path from the spinal ganglion to two
Spinothalamic tract
The anterior and lateral spinothalamic tracts lie in the anterior cord of the white spinal cord. They only lead from the spinal ganglion to the not very distant cord cells, which form the second neuron of this pathway in the dorsal horn of the spinal cord
Neocortex
From a developmental point of view, the neocortex represents the youngest part of the human brain. It can be divided into four interconnected lobes - the frontal lobes, the parietal lobes, the temporal lobes and the occipital lobes
Cell nucleus division
Cell nucleus division, also called mitosis, is part of cell division and is used to renew tissue. It is divided into different phases that are subject to strict controls. Should the control mechanisms fail, it can lead to a
Cerebral ventricle
The brain ventricles are fluid-filled spaces inside the brain. The brain water, the liquor, is produced and stored in them. It serves as a nutrient medium and protection for the brain structures. The liquor flows through the ventricular system between
Cerebellar damage
There are three classic symptoms of damage to the cerebellum. An unsteady, swaying gait indicates ataxia; the typical choppy type of speech is called "chanted language". Furthermore, it is impossible for the patient to determine certain
Forebrain
The forebrain belongs to the central nervous system and includes both the diencephalon and the cerebrum. The diencephalon consists of the thalamus, epithalamus, subthalamus and hypothalamus. The cerebrum surrounds the diencephalon and is made up of sense impressions
The anatomy of the arm

pus
Pus arises from inflammatory reactions. It consists of a collection of dead neutrophils (cells used by the immune system); dead bacteria and tissue fluid. Collections of pus occur, for example, in pimples and can through
Spine anatomy
The spine is divided into cervical, chest, lumbar and sacral spine and guarantees us not only stability but also a certain amount of flexibility. The spine shows some curvatures, so-called lordoses and kyphoses, which are necessary for cushioning
The lymphatic system
The lymphatic system is responsible for the intact immune reaction of the organism. It contains the organs bone marrow, thymus, tonsils, spleen, appendix and the lymph vessels with the lymph nodes.

leg
The leg is the main organ for locomotion of the human body and therefore a very important component for coping with everyday life. So that walking and standing are possible, all structures, their movements and connections must be perfectly aligned
Vessels
Vessels are tubes that carry body fluids through the body. The most important ones are the blood vessels, which can be divided into arterial (oxygen-rich blood) and venous (oxygen-poor blood), as well as the lymph vessels, which are tissue fluids
Ulnar nerve
The ulnar nerve is an important nerve of the arm and consists of fibers that on the one hand transport sensitive tactile information from the skin and joints to the brain and on the other hand perform a motor movement function. In case of damage
The hand of the oath
In the case of a sworn hand, when trying to close the fist, the thumb, index and middle finger are extended while the ring finger and little finger are bent at the same time. The reason for this is nerve damage to the so-called median nerve
