Summary Introduction
To review:
Match the term effector with the most closely related description given below:
Positive feedback
Connects initial segment to cell body
Sensory information
Monitor position/movement of joints
Myelin
One dendrite
Neuron cell bodies in PNS
Blood brain barrier (BBB)
Side branches of axons
Skeletal muscle cells
Introduction:
An effector is defined as a gland, specialized cell, or muscle that is capable of responding to the neural signals. It responds by changing the activity and thereby, generating a specific effect in the body.
