A free nerve ending, as its name implies, is an unencapsulated dendrite of a sensory neuron. Free nerve endings are the most common nerve endings in skin, and they extend into the middle of the epidermis. Free nerve endings are sensitive to painful stimuli, to hot and cold, and to light touch..

Pain perception begins with free nerve endings, which are branches of the primary neuron that are unsheathed at the nerve tips but otherwise surrounded by Schwann cells.

Nociceptors often referred to as your "pain receptors," are free nerve endings located all over the body, including the skin, muscles, joints, bones, and internal organs. They play a pivotal role in how you feel and react to pain.
The Science Dermaxon
The pain and temperature receptors in the dermis of the skin are examples of neurons that have free nerve endings. Also located in the dermis of the skin are lamellated corpuscles, neurons with encapsulated nerve endings that respond to pressure and touch.

Other articles where free nerve ending is discussed: senses: Mechanical senses: The first three, free nerve endings, hair follicle receptors, and Meissner corpuscles, respond to superficial light touch; the next two, Merkel endings and Ruffini endings, to touch pressure; and the last one, Pacinian corpuscles, to vibration. Pacinian corpuscles are built

The skin is the body's largest and primary protective organ, covering its entire external surface and serving as a first-order physical barrier against the environment. Its functions include temperature regulation and protection against ultraviolet (UV) light, trauma, pathogens, microorganisms, and toxins.
Senses The human body
Free nerve endings are the most copious mechanoreceptors found in the epidermis. They are made up of branched termini of sensory fibers. They typically have minimal or no Schwann cells around their fibers.

Define sensory receptor. Define transduction, perception, sensation, and adaptation. Distinguish between tonic and phasic receptors. Compare and contrast the types of sensory receptors based on the type of stimulus (i.e., thermoreceptor, photoreceptor, chemoreceptor, baroreceptor, nociceptor [pain receptor], mechanoreceptor).
Difference Between Free Nerve Endings and Encapsulated Compare the Difference Between Similar
A free nerve ending is an unencapsulated dendrite of a sensory neuron; they are the most common nerve endings in skin. Free nerve endings are sensitive to painful stimuli, to hot and cold, and to light touch. They are slow to adjust to a stimulus and so are less sensitive to abrupt changes in stimulation.
Free Nerveendings, Epidermis by M. I. Walker
The cold receptors present on free nerve endings, that can be either lightly-myelinated or unmyelinated, have a maximum sensitivity at ~ 27°C and will signal temperatures above 17°C. The warm receptors present on free nerve endings are unmyelinated fibers that have a maximum senstivity of ~45°C and will signal temperature above 30°C.
Free Nerve endings vs Sensory receptors? r/AnkiMCAT
A free nerve ending ( FNE) or bare nerve ending, is an unspecialized, afferent nerve fiber sending its signal to a sensory neuron. Afferent in this case means bringing information from the body's periphery toward the brain.
