Concept explainers
To discuss:
The three categories of receptors classified by origin of their stimuli.
Introduction:
Structures that are specialized for the detection of a stimulus, such as pain and heat, are referred to as a sensory receptor. Such receptors can either be real sense organs or simple nerve endings. Sense organs, much complex structures containing receptors, combines with other tissues, such as muscular, epithelial and connective tissues, and with nervous tissues. The nervous tissues enhances the response of the sense organs to a particular kind of stimulus. Sense organs are involved in the transmission of data (through neurons) to the specific place inside the nervous system. Such sense organs may range from simple microscopic structures like dendrites to complex structures like the ear and the eye.

Anatomy and Physiology
- What type of receptor cell is responsible for transducing pain stimuliarrow_forwardSensory receptors are classified functionally according to the following criteria, except :-a- their location in the bodyb- the nature of tissues in which they are foundc- the nature of stimuli acting on themd- their connection with cerebral coretxarrow_forwardOlfactory receptors are foundarrow_forward
- These sensory receptors when activated result in the movement of both calcium and sodiujm ions through them. Facilitated ion channels Sensorineural ion channels Transient receptor potential receptors Guided ligand cahnnelsarrow_forwardA sensory receptor responds when activated, and an electric signal is generated and travels through nerve fibers to the _______ to be analyzed.arrow_forwardIn the sensory pathway for taste Group of answer choices Taste information is carried by the facial, glossopharyngeal, and vagus cranial nerves The receptor cells are the first–order neurons All of these are correct The second order neurons go to the limbic systemarrow_forward
- Which of the following types of cells has the main function of carrying a signal from a sensory receptor to the central nervous system? Sensory Neuron Interneuron Motor Neuron Oligodendrocyte Glial Cellarrow_forwardReceptor fields in the skins are smallest at tip of the nose the cheeks the anterior area of the palm of the hand the fingertip of the index fingerarrow_forwardSite one (1) theory of pain then tell something about it.arrow_forward
- how a receptor differs from an effector with regards to a homeostatic mechanism.arrow_forwardCutaneous receptors are located in the proprioceptors are located in the and cerebral cortex equilibrium These receptors provide sensory input to the primary sensory area of where the information is processed. the muscle spindle pain Cutaneous receptors are made up of numerous sensory receptors, including those for temperature, pressure, touch, and muscles and joints connective tissue One example is a cutaneous receptor that is onion-shaped and detects pressure, called a Pacinian corpuscle sight Proprioceptors help the body maintain and posture. skin of sensory nerve endings wraps around muscle sheath. Golgi tendon A(n) cells within a(n) organs Other sensory receptors, such as organs, are located in the joints.arrow_forwardA sensory receptor responds when activated,and a electric signal is generated and travels through nerve fibers to the ______ to be analarrow_forward
