19
Q

The ANS regulates

A

involuntary movements

20

22
Q

Define Receptor

A

a cell or group of cells that receive information from a stimulus

23
Q

Define Effector

A

an organ, muscle or gland that responds to the control of an autonomic or somatic or endocrine signal

24
Q

Parasympathetic nervous system

A

PNS
Rest and digest, sometimes referred to as the craniosacral division of ANS because of the pregnaglionic neurons
