  2. Somatic nervous system - Wikipedia

    en.wikipedia.org/wiki/Somatic_nervous_system

    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 ...

    The following diagram is provided as an overview of and topical guide to the human nervous system: Human nervous system. Human nervous system – the part of the human body that coordinates a person's voluntary and involuntary actions and transmits signals between different parts of the body. The human nervous system consists of two main parts ...

    The enteric nervous system functions to control the gastrointestinal system. Nerves that exit from the brain are called cranial nerves while those exiting from the spinal cord are called spinal nerves. The nervous system consists of nervous tissue which, at a cellular level, is defined by the presence of a special type of cell, called the ...

  6. Somatosensory system - Wikipedia

    en.wikipedia.org/wiki/Somatosensory_system

    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 ]

  7. Intercostal nerves - Wikipedia

    en.wikipedia.org/wiki/Intercostal_nerves

    The intercostal nerves are part of the somatic nervous system, and arise from the anterior rami of the thoracic spinal nerves from T1 to T11. [1] [2] The intercostal nerves are distributed chiefly to the thoracic pleura and abdominal peritoneum, and differ from the anterior rami of the other spinal nerves in that each pursues an independent course without plexus formation.

  8. Somatotopic arrangement - Wikipedia

    en.wikipedia.org/wiki/Somatotopic_arrangement

    Somatotopy [a] 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 specific body parts and ...

  9. Classification of peripheral nerves - Wikipedia

    en.wikipedia.org/wiki/Classification_of...

    The somatic nervous system directs all voluntary movements of the skeletal muscles, and can be sub-divided into afferent and efferent neuronal flow. The autonomic nervous system is divided primarily into the sympathetic and parasympathetic nervous systems with a third system, the enteric nervous system, receiving less recognition. [2]
