Gap junctions are the most widespread of all cell junctions in animal tissues.
Gap junctions thus couple cells electrically and metabolocially, enabling cells to communicate with each other directly. Gap junctions can open and close wheater functional histology response to changes in calcium levels, and pH. Gap junctions form in a narrow gap of nm, between two adjacent cells.
The picture shows an EM A of two gap junctions between two cells, and a freeze fracture EM B of the particles on the cytoplasmic wheater functional histology of the plasma membrane.
A wheater functional histology of protein molecules called connexins form a structure called a connexon each particle in B above is a connexon. When connexons blue in the diagram to the right from two adjacent cells red and yellow wheater functional histology the diagram align, they form a continuous channel between them.
This tube is called a gastroduodenostomy.
Pyloric stenosis Pyloric stenosis refers to a pylorus that is narrow. This is due to congenital hypertrophy of the pyloric sphincter.
The wheater functional histology of the pylorus is narrower, and less food is able to pass through. The terms basal lamina and basement membrane were often used interchangeably, until it was realised that all three layers seen with the electron microscope represent the single layer seen with the light microscope.
This has led to considerable terminological confusion and, if used, the term basal lamina should be confined to its meaning as lamina densa. Gain a rich understanding of histology through simple, concise text and captions that are thoroughly updated with wheater functional histology most recent research and new discoveries.
