Nose and Nasal Cavity01:24

Nose and Nasal Cavity

5.3K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption

7
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

Anatomy of Respiratory System I: Upper Respiratory Tract01:29

Anatomy of Respiratory System I: Upper Respiratory Tract

2.9K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract....

Pharmacodynamics in Geriatric Patients: Effects of Age

6
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Administering Oxygen by Nasal Cannula01:29

Administering Oxygen by Nasal Cannula

1.2K
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.
Nasal Cannulas
A nasal cannula is a lightweight tube split into two prongs placed in the nostrils,...

Physical Assessment of the Respiratory Tract I: Health History01:28

Physical Assessment of the Respiratory Tract I: Health History

437
Physical assessment of the respiratory tract is critical to patient care. It allows healthcare professionals to identify and manage various respiratory conditions. The process involves a combination of subjective and objective data collection.
Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.
Health history and...

Area of Science:

  • Anthropometry
  • Facial morphology
  • Human growth and development

Background:

  • Nasal dimensions change throughout adulthood.
  • Understanding these changes is crucial for fields like plastic surgery and forensic science.
  • Gender differences in facial structure are well-documented.

Purpose of the Study:

  • To analyze age-related nasal dimension changes.
  • To investigate gender-specific differences in nasal morphology.
  • To evaluate nasal index and nasolabial angle variations with age and gender.

Main Methods:

  • Clinical measurements and profile photographs of 240 subjects (aged 16-50).
  • Subjects categorized into four age groups and by gender.
  • Two-way multivariate analysis of variance (MANOVA) with Duncan's post hoc test used for data analysis.

Main Results:

  • Nasal height and breadth showed an increase with age in both males and females.
  • Nasal index and nasolabial angle did not show consistent age-related changes.
  • Males demonstrated more pronounced nasal changes compared to females within the same age brackets.

Conclusions:

  • Nasal parameters, excluding nasal index and nasolabial angle, increase with age and show significant gender differences.
  • Age-related nasal changes are not uniform across all measured parameters.
  • Males experience greater alterations in nasal dimensions with aging than females.
