Neurotransmitter function

Definition

Neurotransmitter function involves the transmission of chemical signals between neurons in the brain and throughout the nervous system. These signals play a crucial role in regulating physiological processes and maintaining homeostasis.

5 Must Know Facts For Your Next Test

1. Neurotransmitters like dopamine, serotonin, and norepinephrine are essential for mood regulation, which can affect appetite and nutritional choices.
2. Iron deficiency can impair neurotransmitter synthesis, leading to cognitive and behavioral issues.
3. Omega-3 fatty acids support neurotransmitter function by maintaining membrane fluidity, which is critical for signal transmission.
4. Vitamin B6 is a co-factor in the synthesis of several neurotransmitters, including serotonin and dopamine.
5. Proper hydration is necessary for optimal neurotransmitter function as it supports cellular health and nutrient transport.
