True
Which answer below correctly orders the steps that our nervous system takes to sense the world around us?
Sensory receptors in our sense organs receive information, then the message/signal travels through our nerves to our brain, and finally the brain processes this information and decides what to do
Messages/signals travel through our nerves to our brain, then the brain processes this information and decides what to do, and finally the sensory receptors in our sense organs receive information
The brain processes information and decides what to do, then sensory receptors in our sense organs receive information, and finally the message/signal travels through our nerves to our brain
The part of the nervous system that carries signals/messages from our sensory receptors to our brain are ______________.
nerves
hormones
intestines
bones
Sensory receptors in the skin have a different structure than sensory receptors in the eye. The most reasonable explanation for the difference in the structure of these receptors is that –
receptors in the skin are connected to nerve cells, but receptors in the eye are not.
receptors in the eye respond to a different type of input than receptors in the skin.
there are many more sensory receptors in the skin than receptors in the eye.
only the sensory receptors in the eye transmit signals directly to the brain.
This diagram shows the process the body uses to respond to information received through the senses. Which of the following best describes the information that should fill in step 2?
Information stored for later use
Receptors respond to the information
Information carried to the brain
Body systems respond to the information
The illustration below shows the structure of the human eye. The sensory receptors on the back of the eye react to light. The pupil is a hole in the iris, a structure in the front of the eye. Movements of the iris can cause the pupil to become larger or smaller. What observation would provide evidence for the claim that, by controlling the size of the pupil, the iris controls the amount of light that reaches the receptors in the eye?
There are no sensory receptors directly on the pupil at the front of the eye.
Shining a bright light directly away from the eye causes no change in the pupil.
Other animals, such as fish and cats, have a pupil with a very different shape.
The pupil becomes larger in dim light and smaller in bright light.
