Responses

the endocrine system
the endocrine system

autocrine signaling
autocrine signaling

paracrine signaling
paracrine signaling

the nervous system

The correct response is: autocrine signaling.

Autocrine signaling refers to a process where a cell communicates with itself by releasing signaling molecules that bind to receptors on its own surface.
