In other words: if you want to be the next Yves Saint Laurent, it helps to be completely and utterly obsessed with fashion. However, there are many aspects of the profession. Working as a fashion designer can just as well mean supervising a design team at a sportswear company as producing a label under your own name.
Olfactory receptor cells, actually neurons, are the site of transduction. Olfactory receptor cells are the only neurons in the nervous system that are regularly replaced (they last about 4-8 weeks). The size of the epithelium is a good indicator of the acuity of an animal's sense of smell.
Olfaction, also known as olfactics, is the sense of smell. This sense is mediated by specialized sensory cells, called olfactory receptors, in the nasal cavity of vertebrates that are analogous to sensory cells in the antennae of invertebrates. In humans, olfaction â the detection of smells â occurs when odorant molecules bind to specific sites on these receptors.
