What are the 5 sensory receptors in the brain?
Types of Receptors Our brains commonly receive sensory stimuli from our visual, auditory, olfactory, gustatory, and somatosensory systems.
What are Exteroceptive receptors?
Receptors are also classified as exteroceptive (reporting the external environment), interoceptive (sampling the environment of the body itself), and proprioceptive (sensing the posture and movements of the body). Exteroceptors report the senses of sight, hearing, smell, taste, and touch.
What are the 4 different types of general sensory receptors?
The four types of general sensory receptors (and the stimuli that excite them) are nociceptors (pain), thermoreceptors (temperature), mechanoreceptors (physical distortion), and chemoreceptors (chemical con- centration).
What are somatosensory receptors?
Somatosensory Receptor(s): a cell or group of cells specialized to detect changes in the environment and trigger impulses in the sensory nervous system. ( OxfordMed) Specialized to respond to a particular physical property, such as “touch,” “light,” or “temperature.” (

What are the 4 receptors of the skin?
Cutaneous receptors Four receptor structures of the glabrous skin provide this information: Merkel discs, Meissner corpuscles, Pacinian corpuscles, and Ruffini endings.
What are the types of somatosensory receptors?
Somatosensory Receptors Sensory receptors are classified into five categories: mechanoreceptors, thermoreceptors, proprioceptors, pain receptors, and chemoreceptors. These categories are based on the nature of the stimuli that each receptor class transduces.
What are two somatosensory receptors?
These sensory neurons have receptors that are classified according to the stimulus they respond to – there are mechanoreceptors for touch and proprioception, nociceptors for pain, and thermoreceptors for temperature.
What are the major types of drug receptors?
Receptors can be subdivided into four main classes: ligand-gated ion channels, tyrosine kinase-coupled, intracellular steroid and G-protein-coupled (GPCR). Basic characteristics of these receptors along with some drugs that interact with each type are shown in Table 2.
What are some common intercellular receptors?
Intracellular (nuclear) receptors Such hormones are lipophilic to facilitate their movement across the cell membrane. Examples include the thyroid hormones and the large group of steroid hormones, including glucocorticoids, mineralocorticoids and the sex steroid hormones.
Where are the receptors located in the brain?
But a receptor is simply a protein that resides on the membrane of a brain cell. In the past, some have described receptors as a form of neurobiological lock. When a key, or the neurochemical, binds with the lock, the neuron then reads the signal and makes its response by continuing, slowing, or stopping the signal.
What are two types of neurotransmitter receptors in the brain?
Two types of neurotransmitter receptors exist-ligand-gated ion channels, which permit rapid ion flow directly across the outer cell membrane, and G-protein-coupled receptors, which set into motion chemical signaling events within the cell. Hundreds of molecules are known to act as neurotransmitters in the brain.
What are the different types of sensory receptors?
Sensory receptors are primarily classified as chemoreceptors, thermoreceptors, mechanoreceptors, or photoreceptors. Chemoreceptors detect the presence of chemicals.
How are cutaneous touch receptors related to mechanoreceptors?
In both cases, the mechanoreceptors detect physical forces that result from the movement of the local tissue, cutaneous touch receptors provide information to our brain about the external environment, while muscle spindle receptors provide information about our internal environment.
