Draw the circuit diagram of transistor as an oscillator and explain its working. View Solution (a) Draw a diagram of nerve cell and label its parts. (b) In which direction the impulse travels in dendrites and axon ? View Solution
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 ...
Connections between neurons can be mapped by acquiring and analysing electron microscopic brain images. In recent years, this approach has been applied to chunks of brains to reconstruct local connectivity maps that are highly informative1–6, but nevert
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...
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 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. ...
-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....
As connectomics advances, it will become commonplace to know far more about the structure of a nervous system than about its function. The starting point for many investigations will become neuronal wiring diagrams, which will be interpreted to make theo
The asterisk (*) indicates the Mauthner cell soma. f, Coronal planes showing the locations of the ABDM (left) and ABDI (right) neurons at the planes indicated by dotted black lines in the sagittal view. Black boxes highlight nerve bundles from these populations. g, Representative ABDM and...
An agonist can be defined as the "key" required to open the "lock" of the receptor and produce a biochemical or electrical signal to stimulate an effect or response. This response is called the biological response of the cell. Mechanism and Diagram of Agonist Action ...
