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 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.

Back problems are a widespread disease that everyone will probably get to know in the course of their lives. Often, however, it is not the bony components of the spine that cause problems, but the intervertebral discs, also known as intervertebral discs

The entrance area of ​​the basal ganglia is the striatum, also known as the striated body. This part of the brain is networked with the motor nerve tracts and is the first switching point for the interconnection of targeted movements. Degenerations

The synaptic gap represents the gap between two nerve cells in the context of a chemical synapse.

The human mesolimbic system is called the positive reward center. It is part of the central nervous system. It is located in the cerebrum of the human organism.

The orbit is the bony eye socket. Seven bones meet in this receptacle for the eye. The weakest point of the orbit is the floor, which is often affected by fractures after being hit.

Humans have around 350 different olfactory receptors, to whose cilia a specific odor molecule can dock and trigger the activation of the cell. The brain uses the collected messages from the olfactory receptors to create the conscious one

The abdomen is an anatomical unit of the human body that contains various organs and organ systems. The abdomen is the lower front part of the trunk, located between the diaphragm and the pelvis. Also one

The basal ganglia is a group of nerve nuclei that are located in pairs below the cerebral cortex in each of the two halves of the brain. The basal ganglia take on important functions in the control and regulation of processes within

Baroreceptors are mechanoreceptors in human arteries and veins that regulate blood pressure. They are connected to the medulla oblongata and register changes in blood pressure and heart rate. By keeping blood pressure constant

The abdominal cavity, Latin Cavitas abdominalis, refers to the cavity in the area of ​​the trunk in which the abdominal organs are located. It protects the organs and enables them to move against each other.
