Thus, this is the summary of free nerve endings and encapsulated. In fact, free nerve endings are the commonest type of nerve endings that send signals to sensory neurons. However, free nerve endings are more sensitive than encapsulated nerve endings. Moreover, free nerve endings are less specific, while encapsulated nerve endings are highly specific. So, this is the key difference between free nerve endings and encapsulated. Free nerve endings lack encapsulation while encapsulated nerve endings have a brush border encapsulation or fluid-filled sacs at the ends. Nerve endings can be free or encapsulated. Nerve endings act as receptors for receiving signals. The first three types are encapsulated, with the first two (Ruffinis and Pacinis. Summary – Free Nerve Endings vs Encapsulated The innervation of any joint (the TMJ included) involves four types of nerve endings: The first (type I) are Ruffinis corpuscles the second (type II), Pacinis corpuscles the third (type III), Golgi tendon organs and the fourth (type IV), free nerve endings. Moreover, there is a difference between free nerve endings and encapsulated nerve endings in terms of their sensitivity, specificity and adaptability. Thus, free nerve endings do not have encapsulation while encapsulated nerve endings contain either a brush border encapsulation or fluid-filled sacs at the ends. The key difference between free nerve endings and encapsulated nerve endings relies on the presence or absence of the encapsulation. What is the Difference Between Free Nerve Endings and Encapsulated? Both are sensitive to mechanical stimuli.They form mechanoreceptors in the skin.Both free nerve endings and encapsulated nerve endings transmit nerve impulses.What are the Similarities Between Free Nerve Endings and Encapsulated Nerve Endings? However, during abrupt changes in stimulation, free nerve endings require more time for adaptation. Thus, they are sensitive to pain, temperature, pressure, stretch and touch. The sensitivity of free nerve endings is high in comparison to the covered nerve endings. They are most commonly present in the skin and extend to the middle portion of the epidermis. Furthermore, they are encapsulated free nerve endings. Side by Side Comparison – Free Nerve Endings vs Encapsulated Nerve Endings in Tabular Formįree nerve endings are the nerve endings that have no complex sensory structures. Similarities Between Free Nerve Endings and Encapsulated Nerve Endingsĥ. However, there is a difference between free nerve endings and encapsulated nerve endings in terms of their sensitivity, specificity and adaptability. The anatomy and function of free nerve endings in an amphibian skin sensory system. Mechanoreceptors have either free nerve endings or encapsulated nerve endings for their nerve impulse transmission. Nerve endings play an important role in the transmission of nerve impulses. The key difference between free nerve endings and encapsulated nerve endings is that free nerve endings do not have complex sensory structures while the encapsulated nerve endings have either a brush border encapsulation or fluid-filled sacs at the ends.
