Receptor cells

Definition

Receptor cells are specialized cells that receive and transduce signals from hormones, neurotransmitters, and other signaling molecules. They play a crucial role in the body's ability to respond to various stimuli and maintain homeostasis.

5 Must Know Facts For Your Next Test

1. Receptor cells are essential for the functioning of the endocrine system as they detect hormonal signals.
2. Malfunctioning receptor cells can lead to chronic endocrine illnesses such as diabetes or hypothyroidism.
3. Nutrition can impact the efficiency of receptor cells; for instance, deficiencies in certain vitamins and minerals can impair their function.
4. Receptor cell sensitivity can be influenced by diet, with high sugar intake often leading to insulin resistance.
5. Certain nutrients, like omega-3 fatty acids, have been found to improve receptor cell function and reduce inflammation.
