There are four stages of sleep‚ stage 1 occurs when the person decides it’s time to fall asleep. Initially in stage 1 alpha waves start waxing and waning bursts of 8-12 Hz’s EEG. This is when we are alert at our wake fullness. Stage one sleep RRG is low voltage but high frequency signal. As the stages progress into stage 2 there’s a gradual increase in EEG voltage and decrease in EEG frequency. Stage 2 has a higher amplitude and lower frequency and also has two wave forms‚ k complexes and sleep spindles

The sexual response cycle is the sequence of events that happens physiologically when we become sexually aroused. It is divided up into four phases: excitement‚ plateau‚ orgasm‚ and resolution. This cycle is characterized by vasocongestion and myotonia. Vasocongestion in men causes the erection of the penis and‚ in women‚ the vaginal area to swell. The nipples and even the earlobes may swell also. Muscle tension is known as myotonia; this causes spasms in the hands and feet and causes facial grimaces

Children’s food needs vary widely‚ depending on their growth and their level of physical activity. Like energy needs‚ a child’s needs for protein‚ vitamins and minerals increase with age. Ideally‚ children should be accumulating stores of nutrients in preparation for the rapid growth spurt experienced during adolescence. Appropriate weight

go to sleep we cycle through four different stages of sleep. Each of the four cycles are significant. When we initially fall asleep the first cycle is called the NREM1 stage. The next stage is the NREM2 stage and consist of periodic sleep spindles (Excelsior‚ 4TH 16‚ p. 1.18). The third stage is the NREM3 sleep and this simply means you are in the threshold of that deep sleep. The NREM1 and NREM2 stages each last about 20 minutes and the NREM3 last for about 30 minutes. The next stage and arguably

The Four Stages of Labor There are four stages of labor. First Stage of Labor Thinning (effacement) and opening (dilation) of the cervix During the first stage of labor‚ contractions help your cervix to thin and begin to open. This is called effacement and dilation. As your cervix dilates‚ your health care provider will measure the opening in centimeters. One centimeter is a little less than half an inch. During this stage‚ your cervix will widen to about 10 centimeters. This first stage of labor

Cell cycle checkpoints are control mechanisms in eukaryotic cells which ensure proper division of the cell. The Cell Cycle consists of three checkpoints. These checkpoints are the G1 checkpoint‚ the G2 checkpoint‚ and the M checkpoint. These checkpoints all have different functions. Cells have many different mechanisms to restrict cell division‚ repair DNA damage‚ and prevent the development of cancer. Cancers are formed as cells acquire a series of mutations‚ or changes in DNA‚ that make them divide
