Name the five primary taste qualities and the cranial nerves that serve the sense of taste? There are two cranial nerves that innervate the tongue and are used for taste: the facial nerve (cranial nerve VII) and the glossopharyngeal nerve (cranial nerve IX).nswers. Best Answer: There are five primary tastants: sweet, sour, salt, bitter, and umami, which is the taste of the amino acid glutamate, a major ingredient of monosodium glutamate (MSG).

Cranial Nerves of the Face and Mouth: Motion and Sensation Functionality This is mainly thanks in part to the fact that the facial nerve also conveys the sensation of taste from the anterior two-thirds of your tongue. And, even before you put the steak in your mouth, there is saliva inside of your mouth that will help in the process of digestion. Two out of the three of the most important salivary glands are innervated by the facial nerve. These glands are known as the submandibular and sublingual salivary glands. Combined, these two glands produce the vast majority of the saliva in your mouth.

- Olfactory nerves. Also known as CN1, the olfactory nerve is the first of 12 cranial nerves located within the head. It relays sensory data to the brain, and it is responsible for the sense of smell. The nerve's olfactory receptors are located within the mucosa of the nasal cavity. Unlike many other nerves, CN1 does not possess two trunks. Rather, its sensory fibers extend through the ethmoid bone's cribriform plate, a part of the skull located behind the nose.

The Unappreciated Senses CP: The tongue only detects the basic tastes of salt, sweet, bitter, sour, and umami—which is a savory, hearty taste. It's the nose that provides you with the flavor of food. Loss of smell, and with it any experience of food flavor, is quite devastating.

Nasal Anatomy Smell is perceived through part of the roof of the nasal cavity (olfactory cleft) that is just next to the part of the brain responsible for smell (olfactory bulb and fossa). This bony partition in this area (“cribriform” bone) is pierced by numerous nerves (“Olfactory” nerves) on each side.erve Supply. Sensation to the nose is provided to the nasal cavity primarily via branches of the trigeminal nerve. The ophthalmic division (V1) of the trigeminal nerve gives off the anterior and posterior ethmoidal nerves, which supply sensation to the top half of the nasal cavity and septum.

- Cranial Nerves. There are 12 pairs of cranial nerves and because they are nerves, they are considered to be a part of the peripheral nervous system (PNS). Conventionally, each of the 12 pairs of nerves is named using a Roman numeral (I through XII) together with the descriptive name for the nerve.-Olfactory Nerve. is a sensory nerve (a nerve carrying sensation information to the brain) that arises in the nasal mucosa (up through the olfactory foramina of the cribriform plate) and conveys impulses for the sense of smell to the brain.

Chapter 5: Facial sensations & movements The motor portion of. this nerve supplies the muscles of the face and scalp: buccinator, platysma and so on, along with. motor control to the submandibular, sublingual and lacrimal glands. The sensory portion of this. nerve carries sensory information for taste from the anterior 2/3 of the tongue and the palate. Lesions of the facial nerve cause facial paralysis that is usually unilateral. There is also a loss of. taste sensation in the anterior 2/3 of the tongue and decreased salivation.

6. Somatic and Visceral Sensory Systems of the Head The trigeminal sensory system is the somatic sensory system of the face and mouth. The cranial nerves mediating visceral sensation, including taste, are VII, IX and X. (Smell is described in Chapter 14).he objectives of this chapter are to: 1  Describe the organization of the trigeminal sensory system, the somatic sensory system of the head. 2  Describe the organization of the visceral sensory system of the head, including taste sensation.

NERVOUS SYSTEM III: SPECIAL SENSES - Olfactory receptors in the nose: chemoreceptors. - Taste receptors on the tongue: chemoreceptors. - Skin receptors: tactile, mechano, thermo, nociceptors. 2. Visceroreceptors: sensory receptors that produce sensations from organs or internal tissues. - Sensations include pain, hunger, thirst, fatigue or nausea.

The Cranial Nerve Exam The twelve cranial nerves serve the head and neck. The vagus nerve (cranial nerve X) has autonomic functions in the thoracic and superior abdominal cavities. The special senses are served through the cranial nerves, as well as the general senses of the head and neck.The movement of the eyes, face, tongue, throat, and neck are all under the control of cranial nerves.he olfactory, optic, and vestibulocochlear nerves (cranial nerves I, II, and VIII) are dedicated to four of the special senses: smell, vision, equilibrium, and hearing, respectively. Taste sensation is relayed to the brain stem through fibers of the facial and glossopharyngeal nerves.

Chapter 7 - Lower cranial nerve function Both the glossopharyngeal and vagus nerves (CN IX and X) have taste and somatic sensory functions that are not routinely examined. However, the taste function in the glossopharyngeal nerve (CN IX) can be examined if there is suspicion of damage to the nerve (vagus nerve taste function cannot be tested).

Sense There are five basic tastes: sweet, bitter, sour, salty and umami. Other tastes such as calcium[6][7] and free fatty acids[8] may be other basic tastes but have yet to receive widespread acceptance. Taste, gustatory perception, or gustation[1] is one of the five traditional senses.

What is the Glossopharyngeal Nerve? The glossopharyngeal nerve allows perception of taste on the hindmost portion of the tongue. Cranial nerves are vital nerves that arise from the brain that help the brain control muscles, process the five senses, and control glands in the body. Symptoms of glossopharyngeal neuralgia may include ear pain.

Damage to the Cranial Nerves: Consequences and Treatment Options Cranial nerves (CN) I, II and VIII are primarily sensory related. 1  CN I, the olfactory nerve, carries information regarding smell from the nose to the brain. 2  CN II, the optic nerve, carries visual information to the brain for processing. 3  The vestibulocochlear nerve, CN VIII, controls hearing and balance.

LAPAROSCOPIC CHOLECYSTECTOMY Laparoscopic cholecystectomy is a procedure in which the gallbladder is removed by laparoscopic techniques.Laparoscopic surgery also referred to as minimally invasive surgery describes the performance of surgical procedures with the assistance of a video camera and several thin instruments.aparoscopic cholecystectomy is a very safe operation. The overall complication rate is less than 2%. The complication rate for laparoscopic gallbladder surgery is similar to the complication rate for traditional open gallbladder surgery when performed by a properly trained surgeon.
