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.
Answer:
compression of the abdomen to assist in forced expiration
Explanation:
The internal oblique is a muscle that has its location beneath the external abdominal oblique and its closer to the skin than the transverse abdominal muscle.
The internal oblique has different functions such as:
- Supporting the abdominal wall
- Helping in the rotation of the trunk
- Helping to raise pressure in the abdominal area
- Assisting in forced respiration
NAIL IN FOOT:
If your foot wound is bleeding from the nail, put a towel over it to stop the bleeding. Then use water to clean the wound. If you have any antibiotic cream, apply that and cover your wound with either bandages or some old pieces of clothes.
SWOLLEN TOE:
Raise and rest your foot with the swollen toe when you can. Put some ice wrapped in a towel on the toe for up to 20 minutes every 2 to 3 hours. Take a paracetamol if you can. Do not walk or stand for long period of times if it hurts a lot.
hope this helps and i hope you get better soon!
