Nasal cavity

the skull. • The ethmoid bone forms the anterior cranial fossa, a portion of the nasal septum, and the roof of the nasal cavity/lateral walls. • The sphenoid is a butterfly shaped bone-forming part of the orbit. It also articulates with other bones in the cranial (Cancer 2016). • Auditory ossicles contain…

drug. Nose is one of the delicate organs of the human body, as a result of which nasal drug delivery is challenge for formulator. Intranasal drug delivery is now recognized to be a useful and reliable alternative to oral and parenteral routes. One of the major benefits for nasal drug delivery is self medication, along with faster and higher drug absorption achievement. Hussain et al has described regarding the nasal absorption of propranolol in rats was equivalent to intravenous route [1]. This…

it enters the middle layer. The middle layer consists of choroid, ciliary body, iris, pupil, and lens, as well as, the anterior and posterior cavities. Light passes through the pupil in its way to the lens. As it passes through the lens, light passes through the anterior cavity filled with aqueous humor, through the lens, and through the posterior cavity filled with vitreous humor. Light then reaches the internal layer, which includes the retina. The occipital lobe is responsible for receiving…

between the upper and lower respiratory tracts? The upper airways or upper respiratory tract is the parts of the respiratory system lying above the glottis (Vocal cords) • Nose – External breathing organ. • Nasal passages, Inside the nose, the sticky mucous membrane lining the nasal cavity traps dust particles, and tiny hairs called cilia help move them to the nose to be sneezed or blown out • Paranasal Sinuses, - These air-filled spaces alongside the nose help make the skull lighter. •…

bacteria that, by chance, someone pockets support deployment because Minor, rarely, and distortions in the sinus tissue of a person (for example, swelling, inflammation and mucus production, and rarely, facial or nasal trauma). Sinusitis is inflammation of the air cavities within the nasal passages. It can be caused by sinus infection, but can also be caused by chemical irritation or allergy particles of pockets.…

1. Nasal bone a. These bones serve as attachments sites for the cartilaginous tissues that shape the nose (AnatomyExpert, 2014). 2. Nasal Cartilage a. The nasal cartilage articulates with the ethmoid bone to anteriorly separate the nasal passage into two halves (Starkey, Brown, & Ryan, 2011). 3. Zygoma a. The zygoma is a sturture that fused to the maxilla and the temporal bones to form the prominent zygomatic arch beneath the eyes (Starkey, et al., 2011). 4. Maxilla a. The main functions for the…

1. Alveoli- Tiny air sacs in the lungs that conduct the air to the bloodstream. Upon inhalation, oxygen enters the bloodstream; during exhalation, carbon dioxide is released from the bloodstream through the alveoli. Sentence: Even though each human body needs alveoli in their lungs in order to survive, there’s no set amount each adult has to have in order to keep their body moving. 2. Breathiness- A vocal quality characterized by the release of excessive breath because the vocal folds are not…

Sinus Sinus means a hollow or a pocket. It represents cavities in many part of the body, such as the renal sinus, the mastoid sinus, or an aortic sinus.

Upper Respiratory Tract Lower Respiratory Tract Nose Larynx Nasal Cavity Trachea Paranasal Sinuses Bronchial Tree Pharynx Lungs In the upper respiratory tract as air is breathed in and passes through the nasal cavity it is filtered, warmed, and moistened. This air passes through the nasopharynx, the oropharynx, and into the larynx through the epiglottis. The larynx, commonly…
