tactile receptors
- Meissner corpuscles
- Egg-shaped mass of dendrites enclosed
by a capsule of connective tissue.
- Rapidly adapting receptors
- Found in the dermal papillae of hairless skin,
where one's ability to discern spatial location
of touch is highly developed.
- Egg-shaped mass of dendrites enclosed
by a capsule of connective tissue.
- hair root plexuses
- Rapidly adapting touch
receptors found in the hairy skin
- Free nerve endings wrapped
around hair follicles
- Detect movements on the skin
surface that disturb hairs
- Rapidly adapting touch
receptors found in the hairy skin
- Merkel discs
- Also known as type I cutaneous
mechanoreceptors
- Slowly adapting touch receptors
- Saucer-shaped, flattened free nerve endings.
- Found in the fingertips, hands, lips, and external genitalia.
- Also known as type I cutaneous
mechanoreceptors
- Ruffini corpuscles
- Also called as type II cutaneous mechanoreceptors
- Elongated, encapsulated receptors.
- Located deep in the dermis and in ligaments and tendons
- Found in the hands, and soles
- very slowly adapting, therefore, it's important for
signaling continuous states, such is heavy
prolonged touch and pressure signals
- Also called as type II cutaneous mechanoreceptors
- pacinian corpuscles
- Large oval structure composed of a
multilayered connective tissue
capsule that encloses a dendrite
- Fast adapting receptors
- Found around joints, tendons, and
muscles; in the periosteum,
mammary glands, external genitalia,
pancreas and urinary bladder.
- respond to acceleration and
deceleration of joints
during movement
- respond to acceleration and
deceleration of joints
during movement
- Large oval structure composed of a
multilayered connective tissue
capsule that encloses a dendrite
- free nerve endings
- found everywhere in the skin
and in many other tissue.
- can detect pressure and touch
- Thermoreceptorsare free nerve endings
- cold receptors, more in NO.
- warm receptors
- cold receptors, more in NO.
- Free nerve endings and Ruffini corpuscles in
the capsules of joints respond to pressure.
- found everywhere in the skin
and in many other tissue.
