While the eyeball is the actual sensory organ, the other parts of of the eye are equally important in maintaining the health and function of the eye as a whole. The structure of the human eye is such that light can enter, be refracted and trigger nerve impulses back to the brain which ...

to build a three-dimensional cell culture environment, combined with microfluidics can be a Bionic microenvironment in vitro cell culture, while by microelectrodes electrophoresis topology of the network structure can be controlled to achieve aggregation of nerve cells, helping form a specific neural net...
the space between cornea and lens is filled with aqueous humor. The posterior chamber is filled with vitreous humor and consists of the retina. The retina comprises the photosensitive cells which upon receiving light convert them into electrical signals which are carried...
The clitoris is highly sensitive and contains thousands of nerve endings, similar to the penis when aroused due to increased blood flow. Urethra The urethra is located within the vulva vestibule. This is the opening where you pee from, and is a smaller opening than the vagina. ...
Both plant and animal cells have organelles, like mitochondria, which help release energy for the cell. Ribosomes help in protein synthesis, while the Golgi body helps in the packaging and secretion of the proteins. A cell wall provides support and rigidity to the plant cell. Chloroplast present...

When anaction potentialreaches the axon terminal, it activatesvoltage-gated Ca²⁺ channels, resulting in a significant influx of Ca²⁺ ions into the nerve endings. This increase in Ca²⁺ concentration at the presynaptic terminal triggers the release of neurotransmitters fromvesiclescontaini...
-bound structures found within the cell. If you looked at eukaryotic cells under a microscope, you'd see distinct structures of all shapes and sizes. Prokaryotic cells, on the other hand, would look more uniform because they don't have those membrane-bound structures to break up the cell....
