1. which gland influences circadian rhythms through melatonin?

a) thyroid
b) pineal

Explanation:

1. Dopamine is linked to movement and Parkinson's disease as a deficiency in dopamine - producing neurons is associated with Parkinson's.
2. The endocrine system communicates using hormones which are chemical messengers released into the bloodstream.
3. The pituitary gland is called the "master gland" of the endocrine system as it controls the function of many other endocrine glands.
4. The adrenal gland produces adrenaline which is involved in the body's "fight - or - flight" response.
5. The anterior lobe of the pituitary gland releases growth hormone which is important for growth and development.
6. The thyroid gland regulates metabolism by producing thyroid hormones that affect the rate of chemical reactions in the body.
7. The pancreas regulates insulin and blood sugar levels. Insulin helps cells take up glucose from the blood.
8. The parasympathetic nervous system slows down the heartbeat, promoting a "rest - and - digest" state.
9. The main function of the spinal cord is to relay signals between the brain and the body, enabling communication for sensory and motor functions.
10. Hormones are slower but longer - lasting chemical messengers compared to neurotransmitters.
11. The adrenal glands are located above the kidneys.
12. The pineal gland influences circadian rhythms through the production of melatonin.
