A sense is a biological system used by an organism for sensation, the process of gathering information about the surroundings through the detection of stimuli. Although, in some cultures, five human senses [ 1 ] were traditionally identified as such (namely sight , smell , touch , taste , and hearing ), many more are now recognized. [ 2 ]
Taste is the sensation produced when a substance in the mouth reacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue. Taste, along with smell ( olfaction ) and trigeminal nerve stimulation (registering texture, pain, and temperature), determines flavors of food or other substances.
Lhermitte's sign (as if an electrical sensation shoots down back & into arms) loss of consciousness. Syncope (medicine) (R55) neck stiffness; opisthotonus; paralysis and paresis; paresthesia (R20.2) prosopagnosia; somnolence (R40.0) Obstetric / Gynaecological. abnormal vaginal bleeding. vaginal bleeding in early pregnancy / miscarriage; vaginal ...
The end-bulb of Krause or bulboid corpuscle detects temperatures above body temperature. Ruffini's end organ detects temperatures below body temperature. TRPV1 is a heat-activated channel that acts as a small heat detecting thermometer in the membrane which begins the polarization of the neural fiber when exposed to changes in temperature.
The Homonculus is a visual representation of the intensity of sensations derived from different parts of the body. Wilder Penfield and his colleague Herbert Jasper developed the Montreal procedure using an electrode to stimulate different parts of the brain to determine which parts were the cause of the epilepsy.
Receives sensation from the face, mouth and nasal cavity, and innervates the muscles of mastication. VI Abducens: Mainly motor Nuclei lying under the floor of the fourth ventricle Pons. Located in the superior orbital fissure. Innervates the lateral rectus, which abducts the eye. VII Facial: Both sensory and motor Pons (cerebellopontine angle ...
The main functions of the somatosensory system are the perception of external stimuli, the perception of internal stimuli, and the regulation of body position and balance (proprioception). [2] Mechanosensory information includes that of light touch, vibration, pressure and tension in the skin.
In medicine and anatomy, the general senses are the senses which are perceived due to receptors scattered throughout the body such as touch, temperature, and hunger, rather than tied to a specific structure, as the special senses vision or hearing are. [1]
