Anatomy of Respiratory System I: Upper Respiratory Tract01:29

Anatomy of Respiratory System I: Upper Respiratory Tract

5.7K
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....

The Hyoid Bone01:12

The Hyoid Bone

5.5K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

Anatomical Terminology01:20

Anatomical Terminology

28.0K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Anatomy of Respiratory System II: Lower Respiratory Tract

4.3K
The lower respiratory tract is anatomically composed of several vital structures, including the larynx, trachea, bronchial tree, alveoli, lungs, and pleurae. Each component has a specific function, and all are intricately connected to ensure efficient respiration.
The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...

Oral Cavity01:11

Oral Cavity

3.3K
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Tooth Anatomy

2.3K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Summary
This summary is machine-generated.

Tooth loss significantly alters jaw bone shape, impacting nearby nerves and vessels. This change positions the lingual nerve and artery near the alveolar crest, crucial for dental implant planning.

Area of Science:

  • Dentistry
  • Oral surgery
  • Anatomy

Background:

  • Tooth loss causes significant changes in jaw bone morphology.
  • Understanding these changes is vital for procedures involving the oral cavity.

Purpose of the Study:

  • To highlight the morphological alterations in the jaw bone post-tooth loss.
  • To emphasize the clinical significance of these changes on adjacent neurovascular structures.

Main Methods:

  • Analysis of anatomical changes in the mandible following tooth loss.
  • Evaluation of the relative positions of the mylohyoid line, lingual nerve, and lingual artery.

Main Results:

  • Mandibular bone height decreases to the mylohyoid line level after tooth loss.
  • The lingual nerve and artery shift to an area approximating the alveolar crest.

Conclusions:

  • Jaw bone morphology changes dramatically after tooth loss.
  • The altered anatomy necessitates careful consideration of the lingual nerve and artery during dental procedures.
