Autocrine Signaling:This is when a cell secretes hormones or chemical messengers that bind to autocrine receptors on that same cell, leading to changes in the cell. It's like talking to yourself!
Endocrine Signaling:In this type of signaling, glands secrete hormones directly into the blood, which carries them to organs and tissues throughout the body. Imagine this as sending out mass emails - everyone gets the message.
Juxtacrine Signaling:This involves communication between touching cells. The signals pass through protein channels connecting cytoplasms of both cells. It's like whispering secrets hand-to-hand using tin can telephones!
