The fundamental component of the nervous system is the nerve cell, or neuron. Together, neurons form nerves, fibers that transmit impulses all through the body. A protective masking of myelin, a fatty substance, insulates elements of the fibers. The motion of nerve cells is both electrical and chemical. On the ends of each nerve cell there are specialized areas known as synaptic terminals, which include giant numbers of tiny membranous sacs that hold neurotransmitter chemicals. These chemicals transmit nerve impulses from one nerve cell to another. After an electrical nerve impulse has traveled along a neuron, it reaches the terminal and stimulates the discharge of neurotransmitters from their sacs. This process is repeated time and again until a muscle is moved or relaxed or a sensory impression is noted by the brain. These electrochemical events could be considered the "language" of the nervous system, by which info is transmitted from one part of the body to another.

­ There are two main divisions of the nervous system: the central nervous system and the peripheral nervous system. The central nervous system consists of the brain and the spinal cord. The mind lies throughout the skull and governs body functions by sending and receiving messages by the spinal cord. Protecting the brain and spinal cord are bones, layers of tissue, and cerebrospinal fluid. As soon as messages go away the central nervous system, they are carried by the peripheral nervous system. The peripheral system consists of the cranial nerves (nerves branching from the brain) and the spinal nerves (nerves branching from the spinal cord). These nerves convey sensory messages from receptor cells within the body to the central nervous system. Additionally they transport motor impulses from the central system out to the body, where muscles and glands can respond to the impulses. The autonomic nervous system, which is part of the peripheral nervous system, reg-ulates all exercise that is involuntary however crucial for life, including activity of the interior organs and glands.



Working collectively, these divisions coordinate adjustment and reaction of the physique to inside and exterior environmental circumstances. Now that we have covered the nervous system, let's focus on the mind, cerebrospinal fluid, and other associated elements in the subsequent section. MRI machines are commonly used to research the brain. See how much you find out about them in our MRI Quiz. The mind sends messages to and receives stimulation from all components of the physique. More than 10 billion interlinked brain cells regulate the functioning of the physique during sleep and wakefulness. Different areas of the brain control different body functions. On the again of the skull is the cerebellum, which controls coordination of movements, balance, and posture. Deep inside the brain is the thalamus, which is the relay station for brainwave audio program incoming impulses from the remainder of the physique, conveying sensations of ache, touch, and temperature to other components of the brain. The pituitary gland is attached to the hypothalamus by a thin stalk.



Because the pituitary gland controls many of the hormones within the physique, the hypothalamus is taken into account a serious influence on primary drives governed by hormones, resembling starvation, thirst, and sexual need. Overlaying the internal parts of the mind is the cerebral cortex, which consists of two cerebral hemispheres. Positioned in these hemispheres are the nerve centers that regulate thought and voluntary action. Connecting the left and right cerebral hemispheres is a broad band of fibers called the corpus callosum. Because nerve fibers from the 2 cerebral hemispheres cross one another in a structure referred to as the medulla at the bottom of the mind earlier than progressing down the spinal cord, every hemisphere usually controls functions in the opposite facet of the body. For example, a region in the left hemisphere governs motion of the best arm. The mind is the most complicated organ in the body. Though research has recognized a lot of its capabilities in Memory Wave, reasoning, and artistic thought processes, Memory Wave many functions of the mind continue to stay a mystery.
