Clinical and developmental anatomy of olfactory mucosa biology essay
The central nervous system (CNS) consists of the brain and spinal cord. The brain interprets the information received by the spinal cord and generates its own signals and instructions for the body to carry out; Therefore, here we review the state of the art on the characteristics of the nasal mucosa and, in particular, the olfactory mucosa necessary for rational design of intranasal formulations and dosing. Olfaction represents an ancient, evolutionarily critical physiological system. Humans have the ability to detect and distinguish odorants. The sense of smell or smell begins in a small area on the roof of the nasal cavity, which is covered with specialized mucous membrane. From there the olfactory nerve transmits the. The authors RD Alvites, A. Caine, GB Cherubini, J. Prada, ASP Varej o and AC Maur cio in their contribution “The Olfactory Bulb in companion animals - Anatomy, Physiology and Clinical Importance” review the morphofunctional significance of the olfactory bulb in companion animals, emphasizing its significance as potential. At the cellular level, the histological structure of the olfactory mucosa is similar in most mammals. The olfactory epithelium is a pseudostratified columnar epithelium separated from the lamina propria by a basement membrane. The most superficial nuclei in the olfactory epithelium are those of the supporting cells, also called. The olfactory mucosa OM is crucial for the sense of smell and is in direct contact with the sense of smell. Anosmia, loss of the sense of smell, has been linked to the early stages of several abstracts. In this review, the anatomy and physiology of the respiratory mucosa of the nose and paranasal sinuses are summarized under the aspect of its clinical significance. The basic principles of endonasal cleansing, including mucociliary clearance and nasal reflexes, as well as defense mechanisms are explained. Physiological wound healing, aspects of endonasal. The olfactory mucosa OM, derived from the olfactory system, in which neurosensory cells are replaced during adult life, is considered a rich source of cell therapy for central nervous system repair. Design, Setting, and Participants This was a retrospective biocomputational analysis using human ENB and data on normal olfactory mucosal tissue and clinical outcomes. The setting was a large academic medical center. Participants were selected based on available datasets and included ENB patients from all four tumor grades. Years ago, a simple experiment conducted in Tuscany changed the course of bird navigation research: a group of pigeons with severed olfactory nerves were released in an unknown location and never returned, their intact companions quickly flying back to the loft Papi et al. 1971 At that time, the sense of smell was: The olfactory system includes a sensory organ, the olfactory epithelium, and specific olfactory brain areas, the first of which is the olfactory bulb. The perception of odors poses interesting and different problems for the nervous system - problems unique to the world of smell. The first of these is that there is no single dimension. Mesenchymal stem stromal cells of the olfactory mucosa are considered a promising tool in regenerative therapies due to their several beneficial properties, such as multipotency, high proliferation rate, useful location, and few associated ethical concerns. These cells are easily accessible in the nasal cavity of most mammals, including the.
