What is the midbrain? The midbrain (mesencephalon) is a part of the brainstem in the brain. Among other things, it is responsible for the control of coordination. In addition, it plays an important role for hearing and seeing, but also for the sensation of pain. The midbrain consists of different parts: Towards the back (dorsal) … Midbrain (Mesencephalon): Anatomy & Function
The aryepiglottic fold is counted as part of the pharynx in humans. It is a mucosal fold. It is vibrated in during laryngeal singing. What is the aryepiglottic fold? The aryepiglottic fold is called the plica aryepiglottica. It is associated with the medulla oblongata in medicine. The medulla oblongate is approximately 3 cm long. Downward, … Aryepiglottic Fold: Structure, Function & Diseases
Anatomy of the cerebellar bridge angle The cerebellar bridge angle (angulus pontocerebellaris) is the name of a certain anatomical structure of the brain. It is located between the brain stem (consisting of midbrain = mesencephalon, rhombic brain = rhombencephalon and bridge = pons) and the cerebellum and petrous bone. It is located in the posterior … Cerebellar bridge angle
Cerebellar Bridge Angle Syndrome The cerebellar bridge angle syndrome is a combination of symptoms that can occur with tumors in the cerebellar bridge angle (see cerebellar bridge angle tumors). The anatomy of the cerebellar bridge angle allows the derivation of the symptoms. Among the symptoms are: Hearing loss, tinnitus, dizziness, insecure gait (8th cranial nerve … Cerebellar Bridge Angle Syndrome | Cerebellar bridge angle
Reactive movements are motor responses to physical and mental stimuli that are distinct from spontaneous movements. Essentially, reactive movements are based on the stretch-shortening cycle that occurs when muscles are actively lengthened. Reactive force is subject to disturbances in neurogenic lesions of the extrapyramidal system. What are reactive movements? Reactive movements usually correspond to rapid … Reactive Movements: Function, Task & Diseases
Synonym lat. cerebrum, Greek. Encephalon, English: BrainThe brain is the most important organ of vertebrates and forms the superior command center of the central nervous system. It regulates all conscious and unconscious functions and processes. The brain is also the most highly developed organ of vertebrates, as its large number of networked neurons (19-23 billion … Brain
Structure The brain is divided into several brain sections: Belong to the brain stem: The end and diencephalon of the brain together form the forebrain (prosencephalon), the former consisting of the cortex, the basal ganglia and the limbic system. The latter comprises the structures thalamus, epi-, sub- and hypothalamus as well as metathalamus. The brain … Structure | Brain
Midbrain The midbrain represents the place in the brain where important central nervous reflexes are activated and switched. It is also the location of important centers that modulate and coordinate motor programs with the help of messenger substances (neurotransmitters). Dopamine plays an important role here. In some people, the production of dopamine is disturbed and … Midbrain | Brain
Summary In summary, the brain is the most important superordinate instance of our organism. It is here that a multitude of processes are regulated and executed that enable interaction with the environment. The brain also assumes control over important physical processes that influence the growth and development of the organism. Last but not least, the … Summary | Brain
The brain is one of the most complex and intricate structures in the entire human body and continues to puzzle generations of researchers. While the midbrain is only a small part of this complex system, it is nevertheless a small miracle in its own right. What is the midbrain? The midbrain is a part of … Midbrain: Structure, Function & Diseases
Beneath the thalamus lies arguably the most important part of the motor system: the subthalamus. It lies in the midbrain and receives nerve cell nuclei that control certain muscle activities. It represents a pale nucleus; its shape is reminiscent of a lens. This part is one of the regions of the human brain that has … Subthalamus: Structure, Function & Diseases
Human motor function is controlled by an interplay between the two pyramidal tracts and the three extrapyramidal nerve tracts in the spinal cord. Within this framework, the extrapyramidal or extrapyramidal motor system is primarily responsible for involuntary and automated movements. In inflammatory diseases of the central nervous system, as well as in trauma, the extrapyramidal … Extrapyramidal Motor System: Structure, Function & Diseases
