Was sind afferente Nervenbahnen?
Fachbegriff: Nervenbahnen, afferente (auch: Nervenbahnen, aufsteigende) Nervenbahnen, die von der Peripherie über das Rückenmark ins Gehirn verlaufen und sensorische Informationen des Körpers übermitteln.
Wo liegt Sympathikus und Parasympathikus?
Die Nervenbahnen des Sympathikus und Parasympathikus führen vom zentralen Nervensystem (ZNS = Gehirn und Rückenmark) aus zu den Organen. Sie enden beispielsweise an Muskelzellen der Darmwand, des Herzens, an den Schweißdrüsen oder Muskeln, die die Pupillenweite regulieren.
What is the somatic afferent system?
General Somatic Afferent. The general somatic afferent (GSA) system comprises the neurons distributed primarily by the fifth cranial nerve to the surface of the head and all the spinal nerves to the surface of body and limbs that are sensitive to touch, temperature, and noxious stimuli.
What are the somatic afferent receptors sensitive to?
General somatic afferent receptors are sensitive to pain, thermal sensation, touch and pressure, and changes in the position of the body. (Pain and temperature sensation coming from the surface of the body is called exteroceptive, while sensory information arising from tendons, muscles, or joint capsules….
What are the somatic afferent fibers of the auditory nerve?
The general somatic afferent fibers from the posterior aspect of the external auditory canal, lateral pinna, and mastoid region (carried within the posterior auricular nerve) travel centrally in the nervus intermedius to the dorsal part of the primary sensory nucleus of CN V within the pons.
What is the difference between deep somatic and superficial somatic?
Superficial somatic – high density, well localised, rapid sensation Deep somatic – Low density, dull and poorly localised Visceral – Low density, may be sharp tends to be dull. May refer to area of skin What are some sources of pain?
