A three-dimensional computer-generated image of a number of drug-resistant Neisseria gonorrhoeae diplococcal bacteria. Note that extending from the organisms’ exterior were type IV pili, or hair-like appendages.
A cross-section of muscle tissue, surrounded by the extracellular tissue that acts as the connective tissue. Each muscle fiber is joined together by the connective tissue to make up the complete muscle.

NMJ: Light micrograph of synapses between a motor neuron & skeletal muscle cells. The end of the axon of a motor neurone in contact with a muscle cell divides into branches, each one terminating in a motor end plate on a different muscle fibre.
