Dendritic cell drawing

Figure 31-1 (A) Locations of the primary and secondary tissues of the immune system. The primary lymphoid organs are the thymus, which makes T cells, and the hone marrow, which forms B cells. After moving from these organs into the blood circulation the cells reach one of the secondary lymphoid organs, which include lymph nodes, spleen, tonsils, and Peyer s patches on the small intestine. Immature dendritic cells are found in body tissues including skin and mucous membranes and respond to foreign proteins by inducing attack by T lyphocytes and antibody formation by B cells.

Figure 2 A schematic drawing of the airway epithelial layer showing the close association of dendritic cells, airway macrophages, epithelial cells, and particulate matter.

FIGURE 56-7 Repeated exposure to amphetamine or cocaine increases spine density and the number of branched spines in medium spiny neurons, the major cell type of the nucleus accumbens. Left camera lucida drawings of representative dendritic segments. Rats received 20 injections of saline (S), amphetamine (A) or cocaine (C) over 4 weeks and were then left undisturbed for about 1 month prior to analysis. Adapted from Robinson, T.

A synapse is formed where the axon terminal makes an interface with a patch of cell membrane on a dendrite or cell body of another neuron. A schematic drawing of a... 

Fig. 13. Orthogonal arrangement of basket cell axons (thick horizonal fibers oriented in the plane of the Purkinje cells in A and B) and parallel fibers (thin, vertical fibers in A and B). A. Drawing from Golgi-impregnated section, Cajal (1911). B. Bodian-stained section of rat cerebellar cortex. Abbreviations A and B = stellate cells C = basket cell axon E = pericellular basket F = Purkinje cell dendritic tree G = climbing fiber Pb = pericellular baskets. Bar = 100 fim.

Fig. 1. Schematic drawing of hippocampus and slice preparation. (A) Dorsal view of the ventricular surface of the rat hippocampal formation, exposed by removing the neocortex. The hatched bar represents the approximate orientation for slicing. (B) Drawing of isolated hippocampal slice, cut in a near-saggital plane as shown in (A). SUB subiculum CAl, CAS region of small and large pyramids, respectively, from nomenclature of Lorente de No (1934) AD area dentata, containing the granule cell layer FISS hippocampal fissure, PP perforant path input to the granule cells, which send mossy-fiber axons (MF) that synapse on the apical dendrites of CAS pyramidal cells SR stratum radiatum, which includes the Schaffer collateral axons of the CAS pyramids SO stratum oriens, which also contains fibers afferent to pyramidal neurons. The alveus consists mainly of CAl pyramidal cell axons. (From Dingledine et al, 1980.)...
