Groups of these nerve fibers, or axons, are bundled together into fascicles. Each fascicle is wrapped in a protective layer of connective tissue called the perineurium. The perineurium is thicker and stronger than the endoneurium. It comprises parallel layers of flattened cells that provide a...
The difference between pre-mRNA and mRNA is that mRNA lacks noncoding segments called: (A) introns (B) exons (C) axons (D) bosons (E) chevrons Place the following statements of protein synthesis in the correct sequence. a. mRNA moves from the nucleus to the cytosol. b. Peptide bo...

We are taught that a lot of these spiritual diseases are caused by our parents and grandparents. We have been trained by the system that a lot of the diseases we have are due to the DNA that we have received at birth. Thus, if your dad had a problem with depression, this is the re...
Answer and Explanation: Spinal nerves and spinal plexuses are parts of the peripheral nervous system originating from the spinal cord. The differences between the spinal...
than 50 mutated gene products have been identified in patients with hereditary spastic paraplegias, a diverse group of neurological disorders characterized predominantly, but not exclusively, by progressive lower limb spasticity and weakness resulting from distal degeneration of corticospinal tract axons. Mut...
Both B and D are correct. What is the main component of white matter tissue in the central nervous system? a. nerves b. cell bodies c. ligaments d. muscle fibers e. axons What are the divisions of the efferent autonomic nervous system? Stimulation of which c...
Because of the way neurons are shaped and the way they are often grouped together in the body, the cell bodies of neurons are often found in distinct anatomical clusters, with the axons and dendrites relegated to the structural periphery. This aggregation of cell bodies allows for the high-lev...
explores the history of bioelectricity: from Galvani’s epic eighteenth-century battle with the inventor of the battery, Alessandro Volta, to the medical charlatans claiming to use electricity to cure pretty much anything, to advances in the field helped along by the unusually massive axons of ...
Nerves are bundles of thin fibers (made up primarily of axons) that perform the vital function of carrying information from one part of the body to another. They carry information from sensory organs to the central nervous system (brain & spinal cord) and back. ...
