Netter, born in New York in — was a gifted genius. Later he went to med-school at New York University and qualified as an M. D in the year Frank H.
Netter, M. D, a renowned physician and celebrated artist, died in More than 25 new illustrations by Dr.
Machado, including the clinically important fascial columns of the neck, deep veins of the leg, hip bursae, and vasculature of the prostate; and difficult-to-visualize areas like the infratemporal fossa.
New Clinical Tables at the end of each regional section that focus on structures with high clinical significance. Since this enzyme is also produced by noncholinergic neurons, the proper assay is by immunocytochemistry using antibodies against choline acetyltransferase, the acetylcholine-synthesizing enzyme.
Other transmitters and neuropeptides can also be demonstrated by immunocytochemistry C. It has been shown by double-labeling that many neuropeptides are produced together with classical neurotransmitters within the same neuron.
So far, the functional significance of cotransmission, i. The retrograde transport in the direction of the cell body and toward the minus end of the microtubules is mediated by dynein D2 , while the anterograde transport in the direction of the axon terminal and toward the plus end of the microtubules is mediated by kinesin D3.
The transporting vesicles are endowed with several motor proteins, the ATP-binding heads of which interact with the surface of the microtubule in an alternating and reversible fashion. This results in ATP being hydrolyzed, and the released energy is converted into molecular movement that causes the vesicles to roll along the microtubules in the target direction.
The velocity of the rapid intra-axonal transport has been calculated at — mm per day. Proteins, viruses, and toxins reach the perikaryon by retrograde transport from the axon terminals.
In addition to the rapid intra-axonal transport, there is also a continuous flow of axoplasm which is much slower, namely, 1 — 5 mm per day. It can be demonstrated by ligating a single axon E ; proximal to the constricted site, the axoplasm is held back and the axon shows swelling.
The anterograde and retrograde transport mechanisms are used in neuroanatomy to study connecting tracts see p.
Axonal Transport D, E The transmitter substances or their synthesizing enzymes are produced in the perikaryon and must be transported to the axon terminal. The microtubules of the neuron, neurotubules D1 , play a key role in this transport mechanism. If they are destroyed by applying the mitotic poison colchicine, the intra-axonal transport stops.
Most neurotransmitters do not bind to ligand-gated channels but to receptors coupled to G protein. The main difference between the two types of receptors is in the speed of the synaptic response. In the case of ligand-gated ion channels, the activation causes a rapid synaptic potential lasting only for milliseconds.
Activation of G protein-coupled receptors results in responses that last seconds or minutes. G proteins regulate enzymes that produce intracellular messenger substances. These have an effect on ion channels or, via regulatory proteins, on the expression of genes.
