F/col TEM of section through blood platelets Featured April Print

F/col TEM of section through blood platelets

False colour transmission electron micrograph of a section through activated blood platelets. Platelets (thrombocytes) are formed in the bone marrow, and circulate in blood in large numbers. In an unactivated state they are round/oval, whereas activated platelets develop pseudopodia, or extensions from the cell walls. Platelets contain cytoplasmic organelles such as mitochondria (small grey bodies), endoplasmic reticulum & granules (dark stain). Platelets function in 2 ways; they plug defects in the walls of capillaries & also are involved in clott- ing. They also release serotonin, a blood vessel constrictor substance. Mag: x22, 000 at 6x7cm size

False-colour NMR scan of the head, sagittal slice Featured April Print

False-colour NMR scan of the head, sagittal slice

False-colour nuclear magnetic resonance (NMR) image of a mid-sagittal section through a human head, showing structures of a normal brain, airways & facial tissues. The heavily-folded cerebral cortex (the grey matter), which forms the outer part of the cerebrum, is coloured green & yellow. The red curved region in centre is the corpus callosum, a broad band of nervous tissue that connects the two hemispheres of the cerebrum. Beneath it at right appears the feathery outline of the cerebellum. Immediately to the left of the cerebellum (in yellow/red) is the brainstem, an enlarged extension of the spinal cord. Bones of the neck appear to the left of the spinal cord
