Acetylcholine

Definition

Acetylcholine is a chemical that functions in the brain and body as a neurotransmitter, helping to transmit signals across nerves.

Scientific / Technical Definition

Acetylcholine is an ester of acetic acid and choline, acting as a neurotransmitter in both the peripheral nervous system (PNS) and central nervous system (CNS). It plays a crucial role in muscle activation, attention, arousal, and memory.

Benefits

• Supports muscle function
• Enhances memory and cognitive abilities
• Plays a role in attention and learning
• Helps regulate heart rate

Examples

• Eggs (rich in choline, a precursor to acetylcholine)
• Fish
• Meat
• Nuts

Additional Information

• Importance: Acetylcholine is particularly important during pregnancy and lactation as it supports the developing nervous system of the fetus and newborn.

Related Terms

• Choline
• Neurotransmitter
• Synaptic transmission
