![]() ![]() The cerebrum consists of two cerebral hemispheres, the right and left hemisphere are connected by the corpus callosum which facilitates communication between both sides of the brain, with each hemisphere in the main connection to the contralateral side of the body i.e. Traumatic injuries can cause plegia or paresis and may result a wide range of deficits depending on the location and extent of the lesion. Headaches often impair the daily function of patients. Epilepsy can cause uncontrolled excitation. Others may impact cognition such as the various dementias. The demyelination in multiple sclerosis can cause acute attacks, and over time, chronic degradation of function. Some conditions lead to progressively impaired movement eg Parkinson disease. They range dramatically in scope, impact, and nature of the effect. Neurological Conditions: many neurological conditions affect the CNS. The Spinal Cord (the caudal extension of the CNS). The Hemispheres are then further divided into four lobes.ΔΆ. The right and left hemisphere are connected by the corpus callosum which facilitates communication between both sides of the brain. Cerebral hemispheres (comprised of the cerebral cortex, basal ganglia, white matter, hippocampi and amygdalae).Diencephalon, with the thalamus and hypothalamus.Brain stem, consisting of the medulla, pons, and midbrain.The Brain is divided into four main parts : Spinal cord and brain sit in respective cavities ![]() The Nervous System is divided into two main divisions. Muscle contractions and gland secretions are responses to stimuli received by sensory receptors. Motor Output - The nerve impulses from the Central Nervous System go to the effectors ( muscles and glands).Integration - The brain and spinal cord of the Central Nervous System combine and sum up all the data received from the body and send out nerve impulses.Sensory Input - Sensory receptors present in the skin and organs respond to external & internal stimuli by generating nerve impulses that to the central nervous system.The Nervous System has three specific functions: It is well-established that through plasticity of existing cells our nervous systems can adapt to situations not previously encountered, but it also has been shown that cells (NSCs) are plastic and involved in creating new connections in adaptation and response to injury. The nervous system is made up of vast neural networks signalling within these circuits enables thinking, language, feeling, learning, memory, and all function and sensation.
