Hypertonia is a term sometimes used synonymously with spasticity and rigidity in the literature surrounding damage to the central nervous system, namely upper motor neuron lesions. Impaired ability of damaged motor neurons to regulate descending pathways gives rise to disordered spinal reflexes, increased excitability of muscle spindles, and decreased synaptic inhibition. These consequences result in abnormally increased muscle tone of symptomatic muscles. Some authors suggest that the current d
Ectoplasm (from the Greek ektos, meaning outside, and plasma, meaning something formed or molded) is a term coined by Charles Richet to denote a substance or spiritual energy exteriorized by physical mediums.Ectoplasm is said to be associated with the formation of spirits.Ectoplasm is considered to be a hoax, made from cheesecloth, gauze or other natural substances.lthough the term is widespread in popular culture, the physical existence of ectoplasm is not accepted by science.

cytoplasm. Cytoplasm is a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts, and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus.All of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm.The portion of the cytoplasm that is not contained in the organelles is called the cytosol. Although cytoplasm may appear to have no form or structure, it is actually highly organized.A framework of protein scaffolds called the cytoskeleton provides the cytoplasm and the cell with their structure.ll of the organelles in eukaryotic cells, such as the nucleus, endoplasmic reticulum, and mitochondria, are located in the cytoplasm. The portion of the cytoplasm that is not contained in the organelles is called the cytosol. Although cytoplasm may appear to have no form or structure, it is actually highly organized.
