...dendrites. Secondly, they have an area that contains many important cellular components such as the nucleus (containing genetic material) and mitochondria (capable of producing energy). This area is referred to as the cell body. The final key structure is the axon. The axon consists of an area called the axon hillock which integrates all the different inputs across the...

...dendrite cells (typical arm spacing 20 µm). Tensile properties of casting alloys better in all respects than conventionally cast material. Tensile properties of squeeze formed components compare favourably with those of conventionally forged components. Unlike forging, squeeze forming produces isotropic properties with ductilities between that of longitudinal and...

...dendrites’. Note the particularly long extension from the cell body. This is called an ‘axon’. Video 4 Neurons As you’ve just seen, neurons are special cells in the brain which transmit electrical pulses. This is how the different parts of the brain ‘talk’ to each other, and indeed to the rest of the body via other neurons in the ‘nervous system’. You can...

...dendritic (clusters of crystals in fern-like branches). When crystals grow together in a solid mass, in which individual crystals cannot clearly be seen, aggregates are described as massive...Minerals and the crystalline state: 3.2 Colour - The colour of a mineral can be its most obvious feature, but colour can also be one of the least reliable properties for identifying...

...dendrites (from dendron: the Greek for tree). This structure is maintained after the casting is fully solidified, as can be seen from Figure 25(b), which shows a typical casting microstructure. (The image is created by polishing the surface of the metal, immersing it for a short while in a dilute acid and viewing it under an optical microscope.) In addition to the...

...Dendrites extend from the cell body, and this is where information (signals) are received. Each cell also has a single axon, which relays signals onwards to other neurons or to other cells such as muscle. A number of possible arrangements of neural structures are depicted below in Figure 13. [Described image] Figure 13 Different types of neuron. (a) With the cell body at...
