Which of the following statements about proprioceptors is true?
the detect pressure changes in the walls of blood vessels
they detect pain
they monitor the position of joints and skeletal muscles
they are closely related to the sensation of touch
Which sense has receptors throughout the body?
Smell
Taste
Sight
Touch
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.
What special sense receptors take in information about the temperature of the environment and inform your brain.
Your eyes
Your ears
Your skin
