the musculocutaneous nerve is part of the central nervous system - Answer-false, the peripheral nerve
A motor signal is a signal that is sent from a muscle to the central nervous system. - Answer-false, that is
sensory input
the cervical plexus contains nerves that innervate the thigh - Answer-false
tendons connect what type of tissue - Answer-muscle to bone
Acetylcholine is what type of substance? - Answer-neurotransmitter
