Oral Cavity01:11

Oral Cavity

889
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...

Assessment of the Mouth01:26

Assessment of the Mouth

283
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Structure of Lipids03:38

Structure of Lipids

88.8K
Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that include mostly nonpolar carbon-carbon or carbon-hydrogen bonds. Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic...

Membrane Domains01:18

Membrane Domains

5.5K
The membrane domains concentrate specific lipids and proteins at one place within the membrane, which helps in cell signaling, adhesion, and other critical cellular processes. These domains can differ in size, composition, function, and lifespan.
Protein Domains
The membrane comprises a group of distinct proteins responsible for carrying out a cell's specific function. For example, the plasma membrane of the human sperm, or a single germ cell, contains a unique set of proteins in the...

Assembly of the Lipid Bilayer in the ER

3.2K
Biological membranes are more than just a barrier separating cell cytoplasm from the outside environment. They are highly dynamic and help maintain the integrity and physiological stability of the cells as well as membrane-bound organelles. Membranes also play vital roles in cell-to-cell and intracellular communication.
A large chunk of any biological membrane is composed of phospholipids. These lipids have a heterogeneous distribution across different subcellular organelles and even between...

Lipid Absorption01:24

Lipid Absorption

545
Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

Area of Science:

  • Anatomy
  • Aesthetic Medicine
  • Facial Aesthetics

Background:

  • Lip enhancement with soft-tissue fillers is a globally popular aesthetic procedure.
  • Cannula resistance during lip injections suggests the presence of distinct intralabial compartments.
  • Identifying these compartments is key to understanding lip anatomy for cosmetic procedures.

Purpose of the Study:

  • To determine the existence and anatomical characteristics of intralabial compartments.
  • To map the volume, location, boundaries, and dimensions of these compartments.
  • To inform aesthetic injection techniques for improved lip augmentation outcomes.

Main Methods:

  • A cadaveric study involving 20 human body donors (13 male, 7 female).
  • Inclusion criteria: diverse racial backgrounds and age range.
  • Simulation of minimally invasive lip treatments using dye injections to visualize compartments.

Main Results:

  • Identification of 24 distinct lip compartments (6 anterior and 6 posterior in both upper and lower lips).
  • Consistent locations of vertically oriented septations forming compartment boundaries.
  • Defined volume ranges for anterior (0.30–0.39 cc) and posterior (0.44–0.52 cc) compartments, with central areas being larger.

Conclusions:

  • The 24 identified lip compartments significantly influence overall lip shape and aesthetic appearance.
  • A compartment-respecting injection approach may enhance natural lip aesthetics and outcomes.
  • This anatomical understanding can guide practitioners in achieving more predictable and aesthetically pleasing lip augmentation results.
