Vision is the least developed sense at birth as the womb is a dark place and there is little opportunity for development. Vision, like hearing, does develop rapidly over the early years of a baby’s life.

The olfactory tracts begin in the olfactory bulb and proceed to the brain. They are not found in the olfactory epithelium. Atropine eye drops are used to temporarily paralyze the accommodation reflex and as a long-lasting pupil dilating agent, or mydriatic.

Night blindness may exist from birth, or be caused by injury or malnutrition (for example, vitamin A deficiency). It can be described as insufficient adaptation to darkness.

In the tarsal plates lie the Meibomian glands (also known as tarsal glands). These are a specialised type of sebaceous gland that secretes an oily substance onto the eye to slow the evaporation of the eye’s tear film. The oily substance also prevents the eyelids from sticking together when closed.

Rod, one of two types of photoreceptive cells in the retina of the eye in vertebrate animals. Rod cells function as specialized neurons that convert visual stimuli in the form of photons (particles of light) into chemical and electrical stimuli that can be processed by the central nervous system.

The senses of smell and taste are directly related because they both use the same types of receptors. If one’s sense of smell is not functional, then the sense of taste will also not function because of the relationship of the receptors.

The nose and mouth are connected through the same airway which means that you taste and smell foods at the same time. Their sense of taste can recognize salty, sweet, bitter, sour and savoury (umami), but when you combine this with the sense of smell they can recognize many other individual ‘tastes’.

Recovering from the loss And, sadly, some of us might never regain our sense of smell or taste at all. According to some experts, patients with post-viral loss of smell have roughly a 60% to 80% chance of regaining some of their smell function within a year.

The three nerves associated with taste are the facial nerve (cranial nerve VII), which provides fibers to the anterior two-thirds of the tongue; the glossopharyngeal nerve (cranial nerve IX), which provides fibers to the posterior third of the tongue; and the vagus nerve (cranial nerve X), which provides fibers to the …

The flavor of some foods comes primarily from the smell of it. If the sense of smell is lost, because either odor receptors in the nasal cavity or the connection between the nasal cavity and the brain is severed, then the sense of taste will be disturbed as well.

Both methods influence flavor; aromas such as vanilla, for example, can cause something perceived as sweet to taste sweeter. Once an odor is experienced along with a flavor, the two become associated; thus, smell influences taste and taste influences smell.

By far the most important organs of sense are our eyes. We perceive up to 80% of all impressions by means of our sight. And if other senses such as taste or smell stop working, it’s the eyes that best protect us from danger.

Smell is also important as it can affect our sense of taste. Researchers say 80 percent of the flavors we taste come from what we smell, which is why foods can become flavorless when you have a blocked nose.

There are five universally accepted basic tastes that stimulate and are perceived by our taste buds: sweet, salty, sour, bitter and umami.
