Essays on Sense Of Smell

Introduction

Environmental adaptation is essential to the survival of any animal. In fact, this attribute helps organisms obtain nutrients, build homes, withstand extreme weather conditions, attach mates and enhance their safety (Nelson et al. 2008). With this in mind, it is worth appreciating the fact that polar and grizzly bears have different physical and behavioral characteristics due to environmental adaptation in spite of their species similarities. The polar bear is specially adapted to survive in the cold pole regions. Its body structure and genetic composition have substantially evolved to accommodate the low temperatures and harsh environmental conditions. Its behavioral attributes ...

Sensory Perception

The Nervous system plays an important role in many mammals including man. The nervous system is responsible for the coordination of different stimuli in the body. Environmental changes can be felt in the body due to the nervous system present. The sense of touch, vision, audition and taste can be understood solely due to the nervous system. A minute change or deficiency in these senses could lead to fatality. A failure in perception of any of the senses makes an individual dependent. Sensory perception is essential for all living organisms and forms the basis for homeostasis. A ...

Sensory perception is defined as the recognition as well as interpretation of sensory stimuli on the bases of memory. Sensory perception may be accurate or inaccurate data. Memory is the most outstanding element that may be used in defining the accuracy or inaccuracy of a given data. There are various factors that may be used to determine the accuracy of sensory data. Senses being the connection between the world and the human mind it is an extremely critical element for making proper decisions. There are three main reasons that may lead to believe in the accuracy of sensory information. ...

Pollination can simply be described as a mechanism that involves the transfer of pollen contribute to the process of reproduction of plants. this process in plants reproduction entails ferterlization and reproduction (Barret). In scientific terms or biological terms, pollination can be described as the movement or transfer of pollen from one flower's anther to the stigma of same or other flower. This process or step is a pre-requisite for the ferterlization because it allows the fusion of the nuclei from one pollen grain with the nuclei of the ovule of the flower of other plant. The whole essence ...

The five sense organs of human beings: sight, taste, touch, smell and hearing are credited to Aristotle. Sight is considered to be the most developed sense, followed by hearing. More recently, the experts have also added another sense called proprioception, or an awareness of the body in space (Bjorklund 2009). Animals have the sensory receptors to sense their surroundings, and some animals can also sense the electric and magnetic field around them. All the 5 basic senses are the main components of perception. For example, music is associated with hearing, perfume with smell, food with taste, and movies are ...

Sensory perception: Accuracy & fallability

Sensory perception in human beings is far from being perfect. Human eye cannot see beyond the rainbow spectrum of colours (VIBGYOR), even though they are capable of discerning a single colour from several millions of them arranged together. The ear is capable of picking up sounds at frequencies of twenty thousand cycles per second, but that doesn’t mean there aren’t sounds at higher frequencies. Unlike some animals, we cannot sense electric or magnetic fields in our surroundings, but in addition to the five traditional senses, we can also motion and balance, temperature and the relative position of the ...
