Aren't all receptors 'sensory'?

Question

Aren't all receptors 'sensory'?

Answer 1

Nope.  The nerves that receive signals from your brain to control muscles have receptors, too.

Answer 2

"Receptors" is a word that has at least two meanings in biology.  I suspect you are talking about sensory nerves as "receptors."  In that sense, all afferent nerves could be considered "sensory" even if not all those sensations are recognizable at the conscious level.

These days "receptors" are generally a reference to proteins in cell membranes that bind specific molecules.  Among those, not all are "sensory."  Many are purely structural, binding cells to one another or surrounding tissue.  The proper term for a cell membrane receptor that is "sensory" is a "signaling receptor."
