Answer: PARALYSIS
Explanation: Paralysis is a nervous system disorder that is characterised by a complete or partial loss of muscle function.
It is caused by either stroke or spinal cord injury which affects the normal functioning of muscles and nerves in the body.
Paralysis can also be caused by accident of trauma to any of the structures of the nervous system which in turn affects the nerves or muscles.
It can also be caused by a damage to the chain of nerves and muscles that deliver impulses to and from the brain and spinal cord to the nerves and muscles.
When the brain,spinal cord or nerves is damaged by any of the causes mentioned above,the relay signal to the muscles and nerves is damaged or altered,so the signal for one to move do not make it through to the muscles and this results to paralysis.
So Joseph suffers from a loss of of sensation and movement due to injury to his nervous system. He is therefore experiencing PARALYSIS.
Wow thanks for posting this hopefully people see this and get help:)
Answer:
True.
Explanation:
Stage 1 of NREM sleep is characterized by a low amplitude EEG, mixed frequency between range a and s (2 to 7Hz). EMG activity is usually higher than at other stages of sleep, but amplitude can vary widely. Stage 2 of NREM sleep is recognized by background activity and episodes of sleep spindles and K-complexes. Sleep spindles are short (12 to 14 Hz) waves that increase and decrease in amplitude to produce a spindle characteristic. Stage 3 NREM sleep is classified when slow waves or d waves (£ 2Hz) and high amplitude greater than 75mV (measured from lowest to highest wave - peak to peak) appear at 20 to 50% of the time of the day. record. Stage 4 NREM sleep is similar for EEG, EMG, and EOG from the previous stage; however, stage 4 is characterized by the presence of d waves in more than 50% of the time.
Accordingly, we can conclude that going through the NREM stages (1 to 4), the frequency of EEG waves decreases but their amplitude increases.
