Humans can perceive various types of sensations, and with this information, our motor movement is determined. We become aware of the world by way of sensation. Sensations can also be protective to the body, by registering eg environmental cold or warm, and painful needle prick. All the daily activities carry associations with sensations. Broadly, t...
Sight
Ability of the eye(s) to focus and detect images of visible light on photoreceptors in the retina that generate electrical nerve impulses for varying colours, hues, and brightness. 1. 2 Types of Photoreceptors: rods and cones. 1.1. Rods are very sensitive to light, but do not distinguish colours. 1.2. Cones distinguish colours, but are less sensitive to dim light. The inability to see is called blindness. Vision plays an important role in balance and movement, therefore any deficits may have...
Hearing
The sense of sound perception. Mechanoreceptors in the inner ear turn vibration motion into electrical nerve pulses. The vibrations are mechanically conducted from the eardrum through a series of tiny bones to hair-like fibers in the inner ear that detect the mechanical motion of the fibers. Sound can also be detected as vibrations conducted through the body by tactition. The inability to hear is called deafness or hearing impairment. Sense of hearing is of paramount importance in spoken comm...
Taste
Refers to the ability to detect substances such as food, certain minerals, poisons. The sense of taste is often confused with the concept of flavour, which is a combination of taste and smell perception. Flavour depends on odour, texture, and temperature as well as on taste. Humans receive tastes through sensory organs called taste buds, or gustatory calyculi, concentrated on the upper surface of the tongue. Five basic tastes exist: sweet, bitter, sour, salty, and umami. The inability to tast...
Touch
Touch is a perception resulting from the activation of neural receptors in the skin, including hair follicles, tongue, throat, and mucosa. A variety of pressure receptors respond to variations in pressure (firm, brushing, sustained, etc.). The loss or impairment of the ability to feel anything touched is called tactile anesthesia. Paresthesia is a sensation of tingling, pricking, or numbness of the skin that may result from nerve damage and may be permanent or temporary.
Pain or nociception (physiological pain):
Signals nerve and other tissue damage.
Balance or equilibrioception
Allows the sensing of body movement, direction, and acceleration, and to attain and maintain postural equilibrium and balance.
Sensation and perception are two distinct stages of processing during human sensing. Sensation is a function of the low level, biochemical, and neurological mechanisms that allow the receptor cells of a sensory organ to detect an environmental stimulus. Image R: An optical illusion caused by the visual system and characterised by a visual percept t...
The evaluation of sensation is highly dependent on the ability and desire of the patient to cooperate. 1. Sensation belongs to the patient (i.e., is subjective) and the examiner must therefore depend almost entirely on their patient's ability to perceive, understand, and accurately communicate their sensory experiences to different stimuli. One of ...
