The absence of proprioception or two-point tactile discrimination on one side of the body suggests injury to the contralateral side of the primary somatosensory cortex. . However, depending on the extent of the injury, damage can range in loss of proprioception of an individual limb or the entire
The receptor for the sense of balance resides in the vestibular system in the ear (for the three-dimensional orientation of the head, and by inference, the rest of the body). Balance is also mediated by the kinesthetic reflex fed by proprioception (which senses the relative location of the rest of the body to the head). [22]
Nervous system diseases, also known as nervous system or neurological disorders, refers to a small class of medical conditions affecting the nervous system.This category encompasses over 600 different conditions, including genetic disorders, infections, cancer, seizure disorders (such as epilepsy), conditions with a cardiovascular origin (such as stroke), congenital and developmental disorders ...
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
Sensory processing disorder is present in many people with dyspraxia, autism spectrum disorder, and attention deficit hyperactivity disorder (ADHD). Individuals with SPD may inadequately process visual , auditory , olfactory (smell), gustatory (taste), tactile (touch), vestibular (balance), proprioception (body awareness), and interoception ...
Many people with this condition have tingling, weakness, and a reduced ability to feel pain and sense hot and cold. Some affected individuals do not lose sensation, but instead feel shooting pains in their legs and feet. As the disorder progresses, the sensory abnormalities can affect the hands, arms, shoulders, and abdomen.
Sense organs are transducers that convert data from the outer physical world to the realm of the mind where people interpret the information, creating their perception of the world around them. [ 1 ] The receptive field is the area of the body or environment to which a receptor organ and receptor cells respond.
Depending on whether the damage is to the motor nerves, which regulate movement, or the sensory nerves, which affect the senses, the symptoms of a somatic nervous system problem can differ. [15] Damage to the motor nerves shows as: Loss of movement control; Spasms or cramps in muscles; Tremors or twitching; Wasting of muscles (muscle atrophy)
