Study Notes
Interoceptors
- Primarily located in the walls of visceral organs, such as the digestive tract, and in the blood vessels
Free Nerve Endings
- Function: detect pain, temperature, and crude touch
- Found in the dermis, and are responsible for detecting pain, temperature, and crude touch
Specialized Receptors
- Dedicated to specific sensory functions, such as:
- Meissner's corpuscles: detect light touch
- Pacinian corpuscles: detect pressure and vibration
- Merkel's discs: detect sustained touch
Proprioceptors
- Situated in muscles, tendons, and joints
- Function: detect changes in muscle length, tension, and movement
Nerve Endings
- Type: Pacinian corpuscles
- Characterized by: surrounded by connective tissue capsules that enhance sensitivity
- Function: detect pressure and vibration
