|
|
Term
| What does the Exteroceptive system do? |
|
Definition
| 1. Exteroceptive system- senses external stimuli that are applied to the skin. |
|
|
Term

|
Definition
| Proprioceptive system- monitors information about the position of the body that comes fromreceptors in the muscles, joints, and organs of balance. |

3. Merkel's disk
4. Ruffini endings |
|
|
Term
|
Definition
| The identification of objects by touch. |
|
|
Term
| describe the functional difference b/w free nerve endings and Pacinian corpuscles. |
|
Definition
| free nerve endings are particularly sensitive to temperature change and pain. The Paacinian corpuscles respond to sudden displacements in the skin. |
|
|
Term
| Descrine the pathway from the eye to the retina. |
