hair follicles |
| muslces in the hair that pull the hair upright on the skin. |
Arrector Papillae |
| hair is made up of ____ filaments arising from a specialized follicle in the dermis |
Keratin |
| detects light touch (pressure), monitor vibration and adapts to stimuli slowly |
Meissner Corpulse |
| respond to superficial pressure and skin displacement |
Merkel Disk |
| Deep-pressure sensitive, perceives proprioceptive information about joint positions, and adapt to stimuli |
Pacinian Corpulse |
| Stimulated by lowering temperatures and are found widely distributed in the subcutaneous layer |
