The taste buds located on the papillae of the tongue contain specialized nerve receptors called taste receptors. These receptors detect different taste sensations such as sweet, sour, salty, bitter, and umami. Signals from these receptors are transmitted through the gustatory nerve fibers to the brain for interpretation.

What does the tongue do in the nervous system?
Muscles of the tongue are innervated by the hypoglossal nerve (the twelfth cranial nerve, or CN XII). Touch sensation from the anterior two-thirds of the tongue is carried by the trigeminal nerve (CN V), and from the posterior one-third by the glossopharyngeal nerve (CN IX). Taste sensation from the anterior two-thirds of the tongue is from the facial nerve (CN VII), and from the posterior one-third via the glossopharyngeal nerve.

Does A reflex arc begins with a receptor at the end of a sensory nerve?
No, a reflex arc begins with a receptor that detects a stimulus and sends a signal through a sensory nerve to the central nervous system.
What is the difference between a stimulus impulse receptor and effector?
A Receptor is referring to a sense organ, like a nerve ending. An Effector is referring to a muscle capable of reflecting to a stimulus. By definition, receptor and effector are antonyms.
What is nerve ending in the tongue?
Nerve endings in the tongue are specialized sensory receptors that play a crucial role in taste perception and the sensation of texture, temperature, and pain. These endings include taste buds, which contain taste receptor cells that respond to different taste modalities: sweet, sour, salty, bitter, and umami. Additionally, other nerve endings detect tactile sensations and temperature, contributing to the overall experience of eating and drinking. The rich innervation of the tongue helps facilitate communication between the oral cavity and the nervous system.
The condition of this cranial nerve pair is checked by asking a patient to stick out his tongue?
The cranial nerve pair being tested by asking the patient to stick out their tongue is the hypoglossal nerve (CN XII). Dysfunction of this nerve can result in a deviation of the tongue towards the affected side, weakness or atrophy of the tongue muscles, and difficulty with speech and swallowing.
What is a receptor nerve?
Nerve receptor is a specialized cell or nerve endings that respond to sensory stimuli.
What pathway does a nerve impulse follow after initiated into a receptor?
nerve my a$$ nerve
What type receptor is present in the cardiac wall and responds to stimulation by the vagus nerve?
Muscarinic Receptor

What is the sensory receptor in the eyes What is the sensory receptor in the nose What is the sensory receptors in the tongue What is the sensory receptors in the skin?
Eyes: The sensory receptor in the eyes is the photoreceptor cell, specifically the rods and cones, which detect light and color. Nose: The sensory receptor in the nose is the olfactory receptor, located in the olfactory epithelium, which detects odor molecules. Tongue: The sensory receptors in the tongue are taste buds, which contain taste receptor cells that detect different tastes like sweet, salty, bitter, sour, and umami. Skin: The sensory receptors in the skin include mechanoreceptors (detect touch and pressure), thermoreceptors (detect temperature), nociceptors (detect pain), and proprioceptors (detect body position and movement).

Glossopharyngeal nerve passes through what bones?
The glossopharyngeal nerve (cranial nerve IX) passes through the jugular foramen, which is formed by the temporal and occipital bones of the skull. This foramen also allows the passage of the vagus nerve and the accessory nerve. After exiting the skull, the glossopharyngeal nerve branches out to innervate structures in the throat and tongue.
Which of the cutaneous receptor types is most numerous and why?
The most numerous cutaneous receptor type is the free nerve endings. They are found throughout the skin and are responsible for sensing pain and temperature. Their abundance allows for rapid detection of potential harm to the body.
