Question

How do sensory receptors communicate a stimulus to the brain? a. electrical signals b. muscle cells c. corpuscles d. pressure waves

Answer 1

Sensory receptors communicate a stimulus to the brain primarily through **a. electrical signals**. When a sensory receptor detects a stimulus (such as light, sound, touch, etc.), it generates electrical signals (action potentials) that are transmitted along sensory neurons to the central nervous system, where they are processed and interpreted by the brain.
