The somatosensory system, or somatic sensory system is a subset of the sensory nervous system. It has two subdivisions, one for the detection of mechanosensory information related to touch, and the other for the nociception detection of pain and temperature. [1] The main functions of the somatosensory system are the perception of external ...
Brodmann areas 3, 1, and 2 make up the primary somatosensory cortex of the human brain (or S1). [2] Because Brodmann sliced the brain somewhat obliquely, he encountered area 1 first; however, from anterior to posterior , the Brodmann designations are 3, 1, and 2, respectively.
61896. Anatomical terms of neuroanatomy. [edit on Wikidata] In neuroanatomy, the postcentral gyrus is a prominent gyrus in the lateral parietal lobe of the human brain. It is the location of the primary somatosensory cortex, the main sensory receptive area for the sense of touch. Like other sensory areas, there is a map of sensory space in this ...
The primary sensory areas are the primary cortical regions of the five sensory systems in the brain (taste, olfaction, touch, hearing and vision). Except for the olfactory system, they receive sensory information from thalamic nerve projections. The term primary comes from the fact that these cortical areas are the first level in a hierarchy of ...
The sensory nervous system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory neurons (including the sensory receptor cells), neural pathways, and parts of the brain involved in sensory perception and interoception. Commonly recognized sensory systems are those for vision ...
The brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making ...
Somatotopic arrangement. Somatotopy is the point-for-point correspondence of an area of the body to a specific point on the central nervous system. [1] Typically, the area of the body corresponds to a point on the primary somatosensory cortex (postcentral gyrus). This cortex is typically represented as a sensory homunculus which orients the ...
The somatic nervous system (SNS), also known as voluntary nervous system, is a part of the peripheral nervous system (PNS) that links brain and spinal cord to skeletal muscles under conscious control, as well as to sensory receptors in the skin. [1][2] The other part complementary to the somatic nervous system is the autonomic nervous system ...
