Q

What is a sensory receptor?

A

A cell or organ that detects a specific type of stimulus, such as light, sound, or temperature

17
Q

What is a motor end plate?

A

The point where a motor neuron stimulates a muscle fiber

18
Q

What is the role of sensory pathways in the perception of the world around us?

A

They transmit sensory information to the CNS, where it is interpreted and perceived

19
Q

What is the role of motor pathways in interacting with the world around us?

A

They carry commands from the CNS to our muscles, allowing us to move and manipulate objects
