What is a cutaneous sense?
Definition of cutaneous sensation : a sensation (as of warmth, cold, contact, or pain) aroused by stimulation of end organs in the skin.
What is an example of a cutaneous sensation?
any of the senses that are dependent on receptors in the skin sensitive to contact, pressure, vibration, temperature, or pain. Also called skin sense. See pressure sense; temperature sense; touch sense.
Why is cutaneous sensation important?
It demonstrates a rapid response and has a small receptive field; it is useful for detecting texture or movement of objects against the skin. The Ruffini cylinder is located in the dermis and has many branched fibers inside a cylindrical capsule.
What is the function of the cutaneous sensory receptors?
Cutaneous receptors are found at the distal ends of the primary sensory axon; they act as dendrites, in which threshold stimuli lead to the firing of an action potential at the initial segment of the primary sensory axon.
How does cutaneous sensation occur?
Cutaneous sensation is mediated by topographically distributed receptors of several kinds, innervated by different classes of afferent nerve fibers. These receptors are distributed in a grid pattern in the epidermis and dermis (Fig. 42-1; also see Chapters 8 and 34).
What are the major cutaneous sensations?
General Information. An itch is a skin sensation. The other skin sensations are touch, pain, heat, and cold.
What is cutaneous pain?
Superficial somatic pain is caused by stimulation of structures in the skin that sense pain (pain receptors). The word, cutaneous, comes from the Latin word cutis, which means “skin.” It is with that in mind that superficial somatic pain is also called cutaneous pain.
Is taste a cutaneous sense?
Introduction. Taste is no less a cutaneous sense than temperature, touch or pain. The specialized chemoreceptors of the gustatory system work side-by-side in the oral mucosa with thermo-, mechano- and noci-receptors to detect, encode and discriminate the physical properties of the things we eat.
What are the cutaneous senses name them and describe their function?
Answer: The Cutaneous senses are pressure, heat, cold, pain, itch and touch. The function of these sensory receptors is to provide information about the external environment to the central nervous system.
What is cutaneous touch?
Cutaneous Senses include touch and everything else we feel through our skin: temperature, texture, pressure, vibration, and pain. For example, when we run our fingers over a rough surface, receptors in the skin of our fingertips send information about the surface’s texture to our brain.
What are the function of the skin?
Provides a protective barrier against mechanical, thermal and physical injury and hazardous substances. Prevents loss of moisture. Reduces harmful effects of UV radiation. Acts as a sensory organ (touch, detects temperature).
What causes cutaneous sensation?
Cutaneous sensation is mediated by topographically distributed receptors of several kinds, innervated by different classes of afferent nerve fibers. These receptors are distributed in a grid pattern in the epidermis and dermis (Fig.
What is the definition of cutaneous senses?

What are the receptors of the cutaneous skin?
The Cutaneous Skin Senses The skin contains receptors that respond to touch, pressure, and temperature. The relationships between receptors and the cutaneous sensations are not completely understood. Meissner’s corpuscles are sensitive to touch and Pacinian corpuscles to deep pressure.
What is hypoesthesia (losing of sensation)?
Hypoesthesia is total or partial loss of sensation in a part of your body. Sometimes it’s accompanied by a pins-and-needles tingling. In addition to losing a sense of pain, temperature, and touch,…
