Sensitivity: Function, Tasks, Role & Diseases

By sensitivity, medicine understands the perceptive ability of humans. This includes feeling and sensitivity. What is sensitivity? By sensitivity, medicine understands the perceptive ability of human beings. This includes feeling and sensitivity. Medical professionals refer to sensitivity as the ability to perceive various sensations. This ability primarily includes feeling. In addition, the term sensitivity is … Sensitivity: Function, Tasks, Role & Diseases

Parietal Lobe: Structure, Function & Diseases

Without the parietal lobe, humans would not be able to perform spatial reasoning, haptic perceptions, or the controlled execution of hand and eye movements. The cerebral area, which is particularly important for sensory perception, lies between the temporal, frontal, and occipital lobes and, as part of the central nervous system, can be involved in many, … Parietal Lobe: Structure, Function & Diseases

Metathalamus: Structure, Function & Diseases

The metathalamus is a component of the diencephalon and participates in visual and auditory information processing]. Lesions in this area of the brain can accordingly cause visual and auditory disorders due to, for example, strokes, [[circulatory disorders]], increased intracranial pressure, neurodegenerative diseases, tumors, and traumatic brain injury. What is the metathalamus? The metathalamus is an … Metathalamus: Structure, Function & Diseases

Grasping: Function, Task & Diseases

Grasping is an automated movement pattern that is planned in the motor cortex of the brain. From there, the movement plan for reaching is transmitted to the voluntary muscles via the brain‘s pyramidal pathways. Impaired reaching movement may indicate neurodegenerative diseases. What is reaching? Grasping is an automated movement pattern that is planned in the … Grasping: Function, Task & Diseases

Language Center: Structure, Function & Diseases

The language center consists primarily of the Wernicke and Broca areas in the cortical region of the cerebrum and frontal lobe. While the Wernicke area is responsible for semantic language processing, Broca’s area is primarily responsible for syntactic and grammatical language production. Inflammation– or hemorrhage-related damage in one of the areas manifests in speech comprehension … Language Center: Structure, Function & Diseases

Vestibulospinal Reflex: Function, Role & Diseases

The vestibulospinal reflex is a brainstem reflex whose circuitry involves the vestibular organ and nuclei vestibulares. Activation of the reflex causes contraction of the extensor muscles while inhibiting the flexor muscles of the extremities. In decerebration rigidity, the reflex becomes prominent. What is the vestibulospinal reflex? A brainstem reflex is known as the vestibulospinal reflex, … Vestibulospinal Reflex: Function, Role & Diseases

Limbic System: Structure, Function & Diseases

The limbic system is a functional unit in the area of the brain that is responsible for processing emotions. It consists of several parts of the brain that work closely together. Diseases can cause serious discomfort and should be treated promptly. What is the limbic system? The limbic system includes brain areas that are in … Limbic System: Structure, Function & Diseases

Allocortex: Structure, Function & Diseases

The allocortex is a part of the human brain. It is assigned to the cerebral cortex and is a part of the central nervous system. What is the allocortex? The allocortex comprises the regions in the human brain that form three to five layers. It forms about 10% of the cerebral cortex, referred to as … Allocortex: Structure, Function & Diseases

Stereognosy: Function, Tasks, Role & Diseases

Stereognosia is the ability to recognize objects based on mere tactile experience. The postcentral region of the parietal lobe is primarily involved in this ability, in addition to the individual components of the sense of touch. Lesions in these regions can disrupt this ability and cause what is known as astereognosia (stereoagnosia). What is stereognosia? … Stereognosy: Function, Tasks, Role & Diseases

Motor Function: Function, Tasks, Role & Diseases

Motor function is divided into gross motor function and fine motor function. Gross motor skills are the basis of spatial orientation and summarize large movements of the body. Gross motor skills are movement coordination and reaction skills. Fine motor skills refer to dexterity of the hands, facial expressions, and oral motor skills. Gross motor and … Motor Function: Function, Tasks, Role & Diseases

Diencephalon: Structure, Function & Diseases

The diencephalon, also known as the interbrain, is one of the five main major sections of the brain. It works closely with the cerebrum (end brain) and together with it forms what is known as the forebrain. The diencephalon is in turn divided into five other structures, which perform a variety of functions. What is … Diencephalon: Structure, Function & Diseases

Cerebrum: Structure, Function & Diseases

The cerebrum is the largest part of the brain. It occupies the upper part of the skull and consists of two oval hemispheres. Each area of this complex nervous system performs a specific and equally complex function. What is the cerebrum? The cerebrum is also called the end brain, or cerebrum in Latin. This is … Cerebrum: Structure, Function & Diseases
