Hace 2 días · Brain, the mass of nerve tissue in the anterior end of an organism. The brain integrates sensory information and directs motor responses; in higher vertebrates it is also the center of learning. Learn more about the parts and functions of the brain in this article.
Hace 5 días · neuron, basic cell of the nervous system in vertebrates and most invertebrates from the level of the cnidarians (e.g., corals, jellyfish) upward.A typical neuron has a cell body containing a nucleus and two or more long fibres. Impulses are carried along one or more of these fibres, called dendrites, to the cell body; in higher nervous systems, only one fibre, the axon, carries the impulse ...
The myelin sheath is the insulating coating that protects your nerves and helps them quickly and efficiently send signals throughout your body. When the myelin coating is damaged, it can cause various medical conditions that slow or stop the transmission of these signals.
Hace 3 días · Different types of neurons (nerve cells) make up the brain and the nervous system. They send and receive signals that enable us to move, feel sensations, and think. Learn more about how neurons function.
Hace 1 día · Neuroscience is the scientific study of the nervous system (the brain, spinal cord, and peripheral nervous system), its functions and disorders. It is a multidisciplinary science that combines physiology, anatomy, molecular biology, developmental biology, cytology, psychology, physics, computer science, chemistry, medicine, statistics, and mathematical modeling to understand the fundamental ...
Hace 5 días · New approaches to enhance adult neuron growth properties are a key strategy in improving nerve regeneration. Methods Expression and impact of Myc interactome members c-Myc, N-Myc, Mad1, and Max were evaluated within naive and “preconditioned” adult sensory neurons and Schwann cells (SCs), using siRNA and transfection of CRISPR/Cas9 or luciferase reporter in vitro.
Hace 5 días · neuropathy, disorder of the peripheral nervous system. It may be genetic or acquired, progress quickly or slowly, involve motor, sensory, and autonomic ( see autonomic nervous system) nerves, and affect only certain nerves or all of them. It can cause pain or loss of sensation, weakness, paralysis, loss of reflex es, muscle atrophy, or, in ...
