MOTOR NEURON DISEASES. Amyotrophic Lateral Sclerosis (ALS) is a fatal degenerative disorder of upper and lower motor neurons. Lower motor neuron loss causes muscle weakness, atrophy, and fasciculations; upper motor neuron involvement causes spasticity, clonus, hyperactive tendon reflexes, and Babinski signs.OTOR NEURON DISEASES.

Methods of Propagation. I have found that the hazelnut tree is clearly out of the ordinary in a horticultural sense. It has a unique and wonderful side to it. The way in which it achieves pollination in the winter and completion of nut set in the spring, is truly interesting.ue to my overwhelming interest in the tasty Corylus nut, you are invited on a journey to learn about the production and propagation of Hazelnut and the trees that produce them. Introduction. Hazelnuts come from the family Corihave. There are about 18 different species of Corylus.
The harvesting of hazelnuts is done either by hand or by manual or mechanical raking of fallen nuts. Common hazel is widely cultivated for its nuts, including in commercial orchards in Europe, Turkey, Iran and the Caucasus. The name hazelnut applies to the nuts of any of the species of the genus Corylus. This hazelnut, the kernel of the seed, is edible and used raw or roasted, or ground into a paste. The seed has a thin, dark brown skin, which has a bitter flavour and is sometimes removed before cooking.
