Moniz Sign

	Moniz Sign Moniz sign is a clinical sign in which forceful passive plantar flexion of the ankle elicits an extensor plantar reflex. It is found in patients with pyramidal tract lesions, and is one of a number of Babinski-like responses.It is named after Portuguese neurologist António Egas Moniz António Caetano de Abreu Freire Egas Moniz (29 November 1874 – 13 December 1955), known as Egas Moniz (), was a Portuguese neurologist and the developer of cerebral angiography. He is regarded as one of the founders of modern psychosurgery, h .... References {{med-sign-stub Symptoms and signs: Nervous system Reflexes ...

picture info	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 ...

picture info	Plantarflexion Motion, the process of movement, is described using specific anatomical terminology, anatomical terms. Motion includes movement of Organ (anatomy), organs, joints, Limb (anatomy), limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the body parts involved. Anatomy, Anatomists and others use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing unique movements such as those of the hands, feet, and eyes. In general, motion is classified according to the anatomical plane it occurs in. ''Flexion'' and ''extension'' are examples of ''angular'' motions, in which two axes of a joint are brought closer together or moved further apart. ''Rotational'' motion may occur at other joints, for example the shoulder, and are described as ''internal'' or ''external''. Other terms, such as ''elevation'' and ''depression'', descri ...

picture info	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]
	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.

picture info	António Egas Moniz António Caetano de Abreu Freire Egas Moniz (29 November 1874 – 13 December 1955), known as Egas Moniz (), was a Portuguese neurologist and the developer of cerebral angiography. He is regarded as one of the founders of modern psychosurgery, having developed the surgical procedure ''leucotomy''better known today as ''lobotomy''for which he became the first Portuguese national to receive a Nobel Prize in 1949 (shared with Walter Rudolf Hess). He held academic positions, wrote many medical articles and also served in several legislative and diplomatic posts in the Portuguese government. In 1911, he became professor of neurology in Lisbon until his retirement in 1944. Early life and training Moniz was born in Avanca, Estarreja, Portugal, as António Caetano de Abreu Freire de Resende. He attended Escola do Padre José Ramos and the Jesuit-run College of Saint Fidelis and studied medicine at the University of Coimbra, graduating in 1899. For the next 12 years, he served as a le ...
