Cortical Disorder

(the Internet)

Sensitivity - the body's ability to perceive irritation emanating from the environment or from its own organs and tissues. In physiology, the entire set of afferent systems is united by the concept of reception. Sensitivity is a special case of reception when afferent impulses lead to the formation of sensations. Not everything that is subject to reception is felt. For example: the paths of Govers and Fleksig that are afferent to the cerebellum do not reach the cortex, the proprioceptors impulses carried out along these paths are not felt, although they cause responses to the muscles due to the automatism of the cerebellar system. .

Cortical type is characterized by a disorder of sensitivity on the opposite side of the body in terms of hemihypesthesia type (not a complete loss, but only a decrease in sensitivity, a decrease in the intensity of sensations.
It may concern both the entire sensitivity and its individual species or hemianesthesia. Not only symptoms of loss can be observed, but also irritation of a part of the cortex, which is manifested by sensory Jackson seizures.

Cortical Disorder

  1. Polyneuritic type of sensitivity disorder
    The zone and nature of the sensitivity disorder detected in a patient can contribute to the solution of the question of the localization of his pathological focus. Topical diagnostics will undoubtedly become more reliable if this also takes into account information about other changes in the neurological status associated with disorders of sensitivity. With the defeat of various levels of the system
  2. PRIVATE SYMPTOMATOLOGY OF SENSITIVITY DISORDERS
    The lesion of the peripheral nerve trunk causes a violation of all types of sensitivity in the area of ​​its innervation, i.e., in the peripheral mononeuritic type. This results from the fact that in a trunk of a nerve pass nerve fibers for various types of sensitivity. The damage of individual nerve fibers can be more or less deep, which leads to unequal violation of certain types
  3. PRIVATE SYMPTOMATOLOGY OF SENSITIVITY DISORDERS
    The lesion of the peripheral nerve trunk causes a violation of all types of sensitivity in the area of ​​its innervation, i.e., in the peripheral mononeuritic type. The damage to the plexus (cervical, brachial, lumbar, sacral) causes sensory, motor and autonomic disorders in the area innervated by the nerves, combined with pain and paresthesia and belong to
  4. TYPES OF DISTURBANCE OF SENSITIVITY

  5. TYPES OF DISTURBANCE OF SENSITIVITY

  6. Sensitivity and types of sensitivity disorders
    Sensitivity - the body's ability to perceive irritation emanating from the environment or from its own tissues and organs. The analyzer consists of three sections: the receptor, the conductor part and the cortical department. Receptors are the terminal formations of sensory nerve fibers that perceive changes in the body or outside of it and transmit it in the form of impulses.
  7. Type of cnosporidia and type of microsporidia.
    The greatest practical importance has the group Myxosporidia - fish parasites of great practical importance. Mixosporidia (mucus sporoleviki) became known from the middle of X! Xv. The life cycle of myxosporidia takes place entirely in the host, which becomes infected by ingesting spores scattered in the environment. They are multicellular and have two or more sashes connected together. Have
  8. HIGH CORTEX FUNCTIONS
    The cerebral cortex is essentially a gigantic intermediate center on the path from receptor apparatus to effector. All information coming from the external and internal environment flows here, it is compared with current needs, past experience and converted into teams, often covering all life processes. It develops fundamentally new solutions, and
  9. Higher cortical functions and their violations
    In the bark g. M. All the information comes from the external and internal environment, where it is compared with the needs, past experience and is transformed into teams covering all life processes. Different areas of the cortex are associated with receptors and form the cortical parts of the analyzers. Violations. Agnosia - frustration, impossibility of knowledge in the field of one analyzer. There are visual, auditory, tactile,
  10. Diseases of the adrenal cortex
    The adrenal glands consist of two parts: the central (medulla), producing catecholamines, and the peripheral (cortical), secreting steroid hormones. Cortical substance formed of 3 zones. Under the capsule is a narrow glomerular zone (zona glomerulosa), consisting of densely packed groups and clusters of cubic and prismatic cells with dark-colored nuclei and
  11. Central, or cortical, department of the auditory analyzer
    The central end of the auditory analyzer is located in the cortex of the upper temporal lobe of each of the cerebral hemispheres (in the auditory cortex). Particularly important in the perception of sound stimuli are, apparently, the transverse temporal gyrus, or the so-called gyrosl gyrus. As already mentioned, in the medulla oblongata, a partial intersection of nerve fibers occurs, connecting
  12. SYNDROMES OF HIGHER CORK FUNCTION DISTURBANCES
    Disorders of gnosis (agnosia) Gnosis (Greek gnosis - knowledge) is a complex set of analytical-synthetic processes aimed at recognizing an object as a whole and its individual characteristics. Disorders of gnosis are called agnosias. In accordance with the types of human senses, there are visual, auditory, tactile (somatosensory), olfactory, gustatory agnosia. Self
  13. STUDY OF HIGHER CORK FUNCTIONS
    Methods for the study of higher cortical functions are described in detail in the relevant courses (psychology, childhood psychopathology). We will only point out that in the study of the neuro-logical status, gnosis, praxis, speech, memory, thinking are investigated. The necessary information about the mental state of children is obtained during the observation of their mimicry, manner of play, behavior in the new environment, etc.
