Introduction The thalamus is the largest structure of the diencephalon and is located once in each hemisphere. It is a bean-shaped structure connected to each other by a kind of bridge. In addition to the thalamus, other anatomical structures belong to the diencephalon such as the hypothalamus with pituitary gland, the epithalamus with the epiphysis … Thalamus
Thalamic Infarction A thalamic infarction is a stroke in the thalamus, the largest structure of the diencephalon. The cause of this infarction is an occlusion of the supplying vessels, which means that the thalamus is supplied with less blood. As a result, the cells may die and acute neurological symptoms may occur. Depending on which … Thalamic Infarction | Thalamus
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
Neurite is the term used to describe the cell extension of a nerve cell through which electrical impulses are transmitted to its environment. If the neurite is also surrounded by “glial cells” that isolate it, it is called an axon. Function and structure A neurite is the extension of a nerve cell, and directs its … Neurite
A Ranvier lacing ring is a ring-shaped interruption of the fat or myelin sheath surrounding nerve fibers. In the course of “saltatoric excitation conduction” it serves to increase the speed of nerve conduction. Saltatoric, from Latin: saltare = to jump refers to the “jump” of an action potential that takes place when it encounters a … Ranvier lacing ring
Synonyms Greek: Pituitary gland Latin: Glandula pituitaria Anatomy of the pituitary gland The pituitary gland is about the size of a pea and lies in the middle cranial fossa in a bony bulge, the sella turcica (Turkish saddle, due to a shape reminiscent of a saddle). It belongs to the diencephalon and lies in close … Pituitary gland
Diseases of the pituitary gland Synonyms: Hypopituitarism Inflammation, injury, radiation, or bleeding can lead to disorders of the pituitary gland. This can result in the production of hormones in the posterior lobe of the pituitary gland as well as in the anterior lobe of the pituitary gland. Usually, hormone failures occur in combination. This means … Diseases of the pituitary gland | Pituitary gland
Definition Dendrites are the cytoplasmic extensions of a nerve cell, which usually branch off from the nerve cell body (soma) in a knot-like manner and become more and more finely branched in two parts. They serve to receive electrical stimuli from upstream nerve cells via synapses and transmit them to the soma. The dendrites also … Dendrit
Spinous processes Dendrites that do not have a spinous process are called “smooth” dendrites. They pick up nerve impulses directly. While the dendrites have the spines, the nerve impulses can be absorbed through the spines as well as through the dendrite trunk. The thorns emerge from the dendrites like little mushroom heads. They can increase … Spinous processes | Dendrit
Denervation is the cutting of nerves or nerve tracts so that they do not transmit information to the brain and, conversely, the brain can no longer send information via the denervated nerve. In the majority of cases, the procedure is performed to eliminate unwanted, mostly chronic pain. Denervation can also be a therapeutic option for … Reservation
According to Wilhelm The denervation according to Wilhelm describes a surgical technique that is supposed to help people with tennis elbow to relieve their pain. With tennis elbow, the pain is mainly at the tendon attachment points of the elbow bone. By interrupting the transmission of stimuli from two pain-conducting nerves in this area, the … According to Wilhelm | Reservation
