  • Nares- the two oval openings for air to enter the respiratory system Nasal cilia- entraps and prevents large particles (dust, pollen…) to enter the respiratory system
  • Nasal septum- cartilage which divides the nasal cavity into left and right sides Olfactory receptors-located in the upper part of the nasal cavity which is responsible for sending signals to the olfactory bulb Turbinates- three scroll like bones. They increase the surface area for air to pass through. As air is passed through it is filtered, warmed and moistened
  • PATHWAY OF SMELL- air enters the nares into either the left or right (separated by the nasal septum). Into the nasal cavity. When the smell passes over the olfactory receptors in the upper nasal cavity, a signal is sent to the olfactory bulb. Nerve activity in smell…the olfactory bulb (which is an extention of the brain) transmits the stimulus to the olfactory nerve to the limbic system, thalamus, and frontal cortex.
  • A condition in which there is a bend in the cartilage of the nasal septum. Symptoms result due to a blockage of airflow through one nostril headaches difficulty sleeping loud breathing or snoring dry nose nose bleeds Tx- surgical correction temporary tx is external adhesive strip
  • Nasal polyps are soft, painless, noncancerous growths on the lining of your nasal passages or sinuses. They hang down like teardrops or grapes. They are caused from chronic inflammation due to asthma, recurring infection, allergies, drug sensitivity or certain immune disorders. Small nasal polyps may not cause symptoms. Larger growths or groups of nasal polyps can block your nasal passages or lead to breathing problems, a lost sense of smell, and frequent infections. Medications can often shrink or eliminate nasal polyps, but surgery is sometimes needed to remove them. Even after successful treatment, nasal polyps often return.
  • Inflammation of the lining of the nose Caused by allergies, infection, or other factors such as fumes, odors, emotional changes, or drugs Symptoms- nasal congestion, nasal drainage, sneezing, or itching. Tx- eliminating the allergens if possible or reducing them. Antihistimines are effective for short periods of time.
