Neuron schematic drawing

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. 2. Schematic drawing of the adrenergic neurotransmission. Dependent on the target organ, the postsynaptic, G-protein-coupled receptors are of the a -, 2- or /Sj-adrenoceptor subtype. A presynaptic 2-adrenoceptor acts as an inhibitory autoreceptor. The predominant elimination pathway of the transmitter noradrenaline (NA) is the neuronal re-uptake...

Figure 30-8 Schematic drawing of a neuron (after Brand and Westfall,401 p. 1192).

Fig. 4. Schematic drawing of an axon terminal of the noradrenergic neurone in the mouse brain cortex. The axon terminal is endowed with several types of presynaptic receptors including the autoreceptor for noradrenaline itself (which is an a2D-adrenoceptor in this species45) and a variety of heteroreceptors (only the H3 and EP3 heteroreceptors are identified).

Fig. 7. Schematic drawing of a transverse section through the forebrain depicting pathways likely to use glutamate as a neurotransmitter. I = principal subcortical afferents to the thalamus from. somatosensory relay nuclei and the spinal cord (a), cerebellar nuclei (h). and retina (c) 2 = intrinsic neurons and retinal inputs to the hypothalamus 3 = thalamocortical inputs 4 = corticothalamic inputs 5 = cortical inputs to the basal ganglia and other areas in the brainstem and spinal cord 6 = associational and commi.ssural connections in the cerebral cortex. For further details, see Sections 3.5-3.9.

Fig. 5. Superimposition of the schematic drawings of three pyramidal neurons, and the results obtained from the comparison between the mean dendritic density matrices, corresponding to two neuronal samples of C and T rats. Signs + indicating C>T, with P<0.05. Data are from Ruiz-Marcos and Ipina. ...

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.)...

Figure 2. Schematic drawing of a pheromone-detecting sensillum placodeum. In the Japanese beetle, these pheromone detectors house two olfactory receptor neurons (ORNs), one specialized for the detection of pheromone (5,7,8) and the other tuned to the behavioral antagtmist (5,7,8).

Figure 16.3. Schematic drawing of the preparation used for the adult leg reflex response. The fly is decapitated and the femur of the middle leg is immobilized. The tibia is rhythmically flexed by attachment to a movement generator (speaker) at a set frequency (e.g., 2 Hz). Myogram recordings are made from the tibial extensor muscle the reference electrode is placed in the thorax. A cartoon of a typical recording session is shown. (Inset) Neural circuit underlying the resistance reflex. The sensory neurons of the chordotonal organ (flexion Sn) synapse on the motor neuron (Mn), which in turn synapse on the tibial extensor muscle.
