heart attack have pain in their arm, and they might not recognize what is happening to them. 2. Whyolfaction and gustation are considered “chemical” specialsenses? Both olfaction and gustation are chemosensory systems. Chemoreception means a molecule from the environment binds to a...
There are very few “truths” that do not need to be subjected to testing.
All evidence is not equal in quality.
Just because someone is considered to be an authority or to have a lot of expertise does not make everything that person claims automatically true.
Critical thinking requires an open...
Olfaction or olfactory perception is the sense of smell. This sense is mediated by specialized sensory cells of the nasal cavity of vertebrates, which can be considered analogous to sensory cells of the antennae of invertebrates. In humans, olfaction occurs when odorant molecules bind to specific...
There is absolutely no question in my mind that through aromatherapy and the continued use of the process of human olfaction science and the human body can undoubtedly serve the world of medicine better. For example, If a child is restless or uninterested in a classroom, or an adult is tired and or...

Senses are physiological capacities of organisms that provide data for perception. The senses and their operation, classification, and theory are overlapping topics studied by a variety of fields, most notably neuroscience, cognitive psychology (or cognitive science), and philosophy of perception. The...
Why study perception? Human Perception and VR
• Important to understand human abilities and limits • Determine appropriate range for input and output (frame rate, resolution, etc) • Understand that different senses have different ranges and abilities • Determine appropriate sensory channel to use to...
nervous system is the brain, the spinal cord, and nerves. It is present in most animals. It is there to coordinate movement, to process the input of the senses, and to make the animals act a certain way. It is made up of neurons, nerve cells among other things. The structure of the system includes the brain...
Bleach & Rowe-Jones, 1997). There are various disturbances that can cause an individual to suffer from anosmia, including exposure to dangerous chemicals, nasal obstruction/ inflammation, head trauma, neurological diseases and surgical intervention (Mackay-Sim, Grant, Owen, Chant & Silburn, 2004).

and other wastes, the entire organism depends on the function of the system; however, only the organs specifically for the excretion process are considered a part of the excretory system.
As it involves several functions that are only superficially related, it is not usually used in more formal classifications...
SOMATIC & SPECIALSENSES
All senses work in basically the same fashion. Special sensory receptors collect information from the environment and stimulate neurons to send a message to the brain. There the cerebral cortex forms a perception, a person's particular view of the stimulus...
The ABC’s of Sensation
3.1 How do sensations travel through the central nervous system, and why are some sensations ignored?
* Sensation is the activation of receptors located in the eyes, ears, skin, nasal cavities, and tongue.
* Sensory receptors are specialized forms of neurons that are...
