Anatomy

The ciliary ganglion is located on the optic nerve on the back of the eyeball. Parasympathetic fibers innervate the ciliary muscle, the pupil-constricting muscle sphincter pupillae and the inner eye muscles. Lesions in the ciliary ganglion can be

The brachial plexus is a plexus of nerves that, as part of the peripheral nervous system, has three main branches and innervates the shoulders, arms and chest wall. The brachial plexus is made up of anterior spinal nerves of the lowest cervical vertebrae

The pectoralis major muscle is the large pectoral muscle. It participates in the motor control of the arm (internal rotation, adduction, anteversion) and as an auxiliary muscle in breathing. In Poland syndrome, a rare dysplasia, the muscle is missing

The rhombencephalon is a structure in the brain that is made up of an elongated medulla and hindbrain. Its functions include the control of various reflexes, the regulation of vomiting, breathing and blood circulation as well as motor

As the oculomotor nerve, the III. Called cranial nerve. He controls numerous eye movements.

The superior intestinal artery is called the superior mesenteric artery. It supplies blood to several important areas of the body.

The greater omentum is a duplication of the peritoneum that is rich in fatty tissue. The structure plays an important role for the immune defense in the abdominal region.

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 most important part of the motor system lies under the thalamus: the subthalamus. It is located in the midbrain and receives nerve cell nuclei that control certain muscle activities. It is a pale core; its shape is reminiscent of a lens

The occipital lobe is the rearmost part of the cerebrum that contains the primary and secondary visual cortex. This visual center is primarily responsible for processing and interpreting visual sensory impressions. As a result of a cerebral infarction

The olfactory tubercle is a small hump in the skull that houses the human brain. It is part of the olfactory tract. Smell perception comes into human consciousness through him.

The occipital artery is a blood vessel that supplies blood to the muscles of the neck and back. In addition, the artery supplies the occipital region (Regio occipitalis). Pulse-synchronous tinnitus can interfere with occipital artery disorders

The parathyroid gland takes on an essential function in the human body through its participation in the regulation of the calcium and phosphate balance. It is therefore all the more important to recognize symptoms that indicate diseases in good time and

The lowest section of the spine below the sacrum is called the tailbone. It consists of 4 to 5 small vertebrae, the original joints of which have mostly grown together to form a complete bone structure. The tailbone serves mainly

The ascending palatine artery branches off from the facial artery (arteria facialis). Their task is to supply the palatine tonsils (tonsilla palatina) as well as the soft palate (Pallatum molle) and the palatal glands (glandulae palatinae) with oxygen-rich

The precentral gyrus is part of the brain and is home to the primary motor cortex, which is networked with central motor neurons and the pyramidal tracts. The area of ​​the brain is the center of movement control. When lesions occur often

The descending palatine artery (descending palatal artery) is a thin process of the maxillary artery (mandibular artery).

The Ruffini corpuscles are class SA II mechanoreceptors found in the dermis, the skin of the tooth root and the joint capsules. The receptors register intero- and exteroceptive pressure or stretching and conduct these stimuli via the spinal cord

The Meissner corpuscles are RA mechanoreceptors that perceive pressure changes and belong to the differential receptors. Meissner corpuscles only report pressure changes and adapt to constant pressure stimuli. Misperceptions

Vater-Pacini corpuscles are among the mechanoreceptors in the skin that are particularly suitable for the detection of vibrations. A thickening serves as a sensor at the unmarked ends of the otherwise medullary nerves
