![]() An interoceptor is one that interprets stimuli from internal organs and tissues, such as the receptors that sense the increase in blood pressure in the aorta or carotid sinus. ![]() An exteroceptor is a receptor that is located near a stimulus in the external environment, such as the somatosensory receptors that are located in the skin. (Image Credit: "Receptor Types" by OpenStax is licensed under CC BY 4.0)Īnother way that receptors can be classified is based on their location relative to the stimuli. These cells release neurotransmitters onto a bipolar cell, which then synapses with the optic nerve neurons. However, it is the sensory nerve endings on. The senses of touch and pressure utilize both of these. There are also sensory nerves encircling hair follicles that give information on when the hair is displaced. In c, photoreceptors in the eyes, such as rod cells depicted here, are examples of specialized receptor cells. General sensory receptors are nerve endings of two types: nonencapsulated (free) or encap-sulated. temperature changes, When receptors are continuously stimulated, the sensations may fade away this phenomenon is known as A. pain, Thermoreceptors are associated with A. Sensory neurons can have either free nerve endings on their dendritic side such as in a or encapsulated endings where dendrites are covered by connective tissue such as in b. Study with Quizlet and memorize flashcards containing terms like General senses include all of the following except A. Sensory receptors can be classified on the basis of their structure. 2 types of free nerve endings that give us Nocloception for sensing pain and. In other words, they express polymodality. They receive data and feedback from the sensory organs and from nerves. \): Receptor Classification by Cell Type. Thus, different free nerve endings work as thermoreceptors, cutaneous mechanoreceptors and nociceptors.
