Somatic sensory input comes from the receptors of the eyes, ears, nose, tongue, and skin. These organs transmit information we associate with the five senses. Visceral sensory input comes from (surprise!) the viscera, or internal organs. … The motor division of the PNS also has visceral and somatic branches.
What are somatic and visceral sensations?
Somatic pain and visceral pain are two distinct types of pain, and they feel different. Somatic pain comes from the skin. muscles, and soft tissues, while visceral pain comes from the internal organs.
What are somatic sensory?
Overview. The somatic sensory system has two major components: a subsystem for the detection of mechanical stimuli (e.g., light touch, vibration, pressure, and cutaneous tension), and a subsystem for the detection of painful stimuli and temperature.
What are visceral sensors?
The visceral nervous system, in turn, is composed of sensors for internal conditions and effectors controlling body homeostasis . … The vertebrate somatic-visceral ‘duality’ is reflected by the differential usage of specific homeodomain transcription factors that drive cell-type specification.
What is an example of visceral sensory?
Conscious sensations arising from the viscera, in addition to pain, include organ filling, bloating and distension, dyspnea, and nausea, whereas non-visceral afferent activity gives rise to sensations such as touch, pinch, heat, cutting, crush, and vibration. Both sensory systems can detect chemical stimuli.
What is an example of somatic pain?
Somatic pain usually feels like a constant aching or gnawing sensation. It can be further classified as either deep or superficial: For example, a tear in a tendon will cause deep somatic pain, while a canker sore on your inner check causes superficial somatic pain.
What are the 4 somatic senses?
Somatic senses (“soma” means body) detect touch, pain pressure, temperature, and tension on the skin and in internal organs.
What are visceral activities?
The visceral (or autonomic) motor system controls involuntary functions mediated by the activity of smooth muscle fibers, cardiac muscle fibers, and glands. … Conversely, parasympathetic system activity predominates during states of relative quiescence, so that energy sources previously expended can be restored.
What is the meaning of visceral sensation?
Visceral: Referring to the viscera, the internal organs of the body, specifically those within the chest (as the heart or lungs) or abdomen (as the liver, pancreas or intestines). In a figurative sense, something “visceral” is felt “deep down.” It is a “gut feeling.”
