Biopsychology - The Endocrine System

The Endocrine System

The network of glands in the body that produce + secrete hormones. Works alongside the nervous system to control vital bodily functions.

Glands

Secrete and produce hormones. Many different ones/types (e.g. Pituary gland, adrenal gland). Different glands produce different hormones.

Hormones

Chemical messengers that travel in the bloodstream (unlike neurotransmitters). Only effect target cells with receptors for specific hormones. When enough receptors are stimulated by hormones this causes a physiological reaction (change) in a target cell. 

Target cells

Cells with the receptors for a specific hormone and therefore can effected by this type of hormone. When enough of these receptors are stimulated by hormones a physiological reaction is caused in the cell.
