Body’s 2nd largest communication system for sending info to and from the brain. System utilizes chemical messages called hormones

“Master Gland”, Secretes hormones that provide signals for other glands

Receives information and passes it on, sorts information in the brain.

Coiled, bony, fluid-filled tube in the inner ear that transforms sound vibrations to auditory signals.

most sensitive to color and higher levels of light

most effective in lower light conditions, black and white.

lets in different amounts of light, a hole in your eye

the outer later of protection of the eye

temperature, pressure, and pain

monocular depth cues allow us to see in 3D with one eye, but best with both.

The smallest amount of energy (stimulus) that produces a sensation at least half the time

The just noticeable difference between stimuli (ex: hearing tests, vision tests)

The stronger the stimulus, the larger the change required for the observer to notice. Example: adding one pound to a 10 pound weight vs adding one pound to a 50 pound weight

Meissner’s and Pacinian Corpuscles

Temperature Receptors

Ruffin Endings (heat) & Krause Bulbs (cold)

Body Movement (moving arms and legs)

Vestibular Sense Stimulus

Change in rate or direction of motion (when you spin in a circle)
