Rossolimo's Sign
Rossolimo's sign is a clinical sign in which percussion of the tips of the toes causes an exaggerated flexion of the toes. It is found in patients with pyramidal tract lesions, and is one of a number of Babinski-like responses. The sign is named after Grigory Ivanovich Rossolimo Grigory Ivanovich Rossolimo (russian: Григо́рий Ива́нович Россоли́мо) ( – September 1928) was a Russian Empire and Soviet neurologist who was a native of Odessa.

Medical Sign
Signs and symptoms are the observed or detectable signs, and experienced symptoms of an illness, injury, or condition. A sign for example may be a higher or lower temperature than normal, raised or lowered blood pressure or an abnormality showing on a medical scan. A symptom is something out of the ordinary that is experienced by an individual such as feeling feverish, a headache or other pain or pains in the body. Signs and symptoms Signs A medical sign is an objective observable indication of a disease, injury, or abnormal physiological state that may be detected during a physical examination, examining the patient history, or diagnostic procedure. These signs are visible or otherwise detectable such as a rash or bruise. Medical signs, along with symptoms, assist in formulating diagnostic hypothesis. Examples of signs include elevated blood pressure, nail clubbing of the fingernails or toenails, staggering gait, and arcus senilis and arcus juvenilis of the eyes. Indicati ...

Corticospinal Tract
The corticospinal tract is a white matter motor pathway starting at the cerebral cortex that terminates on lower motor neurons and interneurons in the spinal cord, controlling movements of the limbs and trunk. There are more than one million neurons in the corticospinal tract, and they become myelinated usually in the first two years of life. The corticospinal tract is one of the pyramidal tracts, the other being the corticobulbar tract. Anatomy The corticospinal tract originates in several parts of the brain, including not just the motor areas, but also the primary somatosensory cortex and premotor areas. Most of the neurons originate in the primary motor cortex (precentral gyrus, Brodmann area 4) or the premotor frontal areas.Purves, D. et al. (2012). Neuroscience: Fifth edition.

Plantar Reflex
The plantar reflex is a reflex elicited when the sole of the foot is stimulated with a blunt instrument. The reflex can take one of two forms. In healthy adults, the plantar reflex causes a downward response of the hallux (flexion). An upward response (extension) of the hallux is known as the Babinski response or Babinski sign, named after the neurologist Joseph Babinski. The presence of the Babinski sign can identify disease of the spinal cord and brain in adults, and also exists as a primitive reflex in infants. While first described in the medical literature by Babinski in 1896, the reflex has been identified in art at least as early as Botticelli's '' Virgin and Child with an Angel'', painted in the mid- 15th century. Methods The lateral side of the sole of the foot is rubbed with a blunt instrument or device so as not to cause pain, discomfort, or injury to the skin; the instrument is run from the heel along a curve to the toes (metatarsal pads). Many reflex hammers ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grigory Ivanovich Rossolimo
Grigory Ivanovich Rossolimo (russian: Григо́рий Ива́нович Россоли́мо) ( – September 1928) was a Russian Empire and Soviet neurologist who was a native of Odessa. (He was of Greek origin; his grandfather had gone sailing from Cephalonia as a young man, been shipwrecked, and washed up near Odessa, where he remained for the rest of his life.) He specialized in the field of child neuropsychology. Biography In 1884 he graduated from the University of Moscow, and subsequently worked under Aleksei Kozhevnikov (1836-1902) at the clinic of neurological diseases. He earned his medical doctorate in 1887, and in 1890 became head of the department of neurology at the clinic of Aleksei Alekseevich Ostroumov (1844-1908). In 1911, along with other academic personnel at the University of Moscow, he resigned in protest against reactionary reforms installed by the minister of education. Afterwards, he opened his own institute of neurology and child psychology. In 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
