A somatosensory pathway will typically have three neurons: [18] first-order, second-order, and third-order. [ 19 ] The first-order neuron is a type of pseudounipolar neuron and always has its cell body in the dorsal root ganglion of the spinal nerve with a peripheral axon innervating touch mechanoreceptors and a central axon synapsing on the ...
The third-order neurons are in the ventral posterolateral nucleus in the thalamus and fibres from these ascend to the postcentral gyrus. Sensory information from the upper half of the body is received at the cervical level of the spinal cord and carried in the cuneate tract, and information from the lower body is received at the lumbar level ...
Speech recognition and word recognition tests measure how well an individual can hear normal day-to-day conversation. The participant is told to repeat conversation being spoken at different volumes. The spondee threshold test is a related test that detects the loudness at which the participant is able to repeat half of a list of two syllable ...
Somatosensation is considered a general sense, as opposed to the special senses discussed in this section. Somatosensation is the group of sensory modalities that are associated with touch and interoception. The modalities of somatosensation include pressure, vibration, light touch, tickle, itch, temperature, pain, kinesthesia. [18]
In neuroanatomy, the trigeminal nerve (lit. triplet nerve), also known as the fifth cranial nerve, cranial nerve V, or simply CN V, is a cranial nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the most complex of the cranial nerves.
The extra categories may be termed fourth person, fifth person, etc. Such terms are not absolute but can refer, depending on context, to any of several phenomena. Some Algonquian languages and Salishan languages divide the category of third person into two parts: proximate for a more topical third person, and obviative for a less topical third ...
The insular cortex (also insula and insular lobe) is a portion of the cerebral cortex folded deep within the lateral sulcus (the fissure separating the temporal lobe from the parietal and frontal lobes) within each hemisphere of the mammalian brain.
School exercise books in New Zealand generally conform to standard NZS 8132:1984 (Specification for school stationery). An alphanumeric code is used to describe the exercise book's binding, format, and size. The first numerals(s) refer to the binding: 1 for softcover; 2 for hardcover; 8 for spiral bound; The letter refers to the format: A for ...
