Final answer:
The components of the brain that can be affected in a patient experiencing insomnia are the Pineal gland, Hypothalamus, and Cerebrum.
Step-by-step explanation:
Three components of the brain that can be affected in a patient experiencing insomnia are the Pineal gland, Hypothalamus, and Cerebrum.
The Pineal gland produces melatonin, a hormone that regulates sleep-wake cycles. In individuals with insomnia, the Pineal gland may have reduced production or disrupted release of melatonin, contributing to sleep difficulties.
The Hypothalamus plays a crucial role in regulating sleep. It controls the release of sleep-promoting hormones such as melatonin and regulates the sleep-wake cycle. Dysfunction in the Hypothalamus can lead to insomnia.
The Cerebrum is responsible for higher cognitive functions, including sleep regulation. Any disruption or abnormality in the Cerebrum can affect sleep patterns, leading to insomnia.
