Q

Sleep Wake Cycle

A

The natural biological rythm of transitioning into sleep and wakefulness over 24hr period

16
Q

Ultradian rhythm

A

short cycles that occur withiness less thab 24hr and dertmines rhe timing and duration of sleep stages. Also reguates circadian rhythm

17
Q

Suprachiasmatic nucleus

A

regulates tje timinig and acticity of sleep-wake-cycle. Receives information about the amount of light from the eyes and sends messages to oineal gland to release melatonon into blood

(low light - more sleepy)

18
Q

Partial sleep deprivation

A

Getting some sleep in 24hr period but less that required for optimal daytime functioning

19
Q

Full/ Total sleep deprivation

A

Going without any sleep in 24 hr period

20
Q

Melatonin

A

hormone released by the pineal gland that causes drownsness and helpes regulate sleep-wake cycle

20
Q

Affective

A

persons behavioural responses that relate to the display and control of emotions and feelings

Resulting in sleepness and early moirning insomnia (inability to sleep)

22
Q

BAC (blood alcohol conncetration)

(CR?)

25
