The Nervous System is the system of cells, tissues, and organs that regulates the body's responses to internal and external stimuli. In vertebrates it consists of the brain, spinal cord, nerves, ganglia, and parts of the receptor and effector organs. Your nervous system is composed of the central nervous system, the cranial nerves, and the peripheral nerves. The brain and spinal cord together form the central nervous system. The cranial nerves connect the brain to the head. The four groups of...

The Nervous System The nervous system is the most complex part of the body, as they govern our thoughts, feelings, and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease, stroke, accidents, etc. The nervous system is a network of neurons (nerve cells) that that sends information to the brain to be analyzed.

Nervous System- Nerve Impulse When a stimulus is strong enough, a nerve impulse is generated in an "all or none" response which means that a stimulus strong enough to generate a nerve impulse has been given. The stimulus triggers chemical and electrical changes in the neuron. Before an impulse is received, a resting neuron is polarized with different charges on either side of the cell membrane. The exterior of the cell is positively charged with a larger number of sodium ions present compared...

Disorders of the Nervous System The way we think, our emotions, and the ability of our body to tell itself to move all connect back to the nervous system. If one part is not connected to another or if something never developed properly it can create a major problem. Disorders can occur within the brain or can be malfunctions of the nerves. Disorders can range from Palsy and Parkinson’s in which symptoms are movements such as tremors to Alzheimer’s which is mental deterioration and loss of...

Together with the peripheral nervous system (PNS), the other major portion of the nervous system, the CNS coordinates the body's interaction with the environment. The CNS is contained within the dorsal cavity, with the brain in the cranial subcavity (the skull), and the spinal cord in the spinal cavity (within the vertebral column). Then human nervous system is the...

It is amazing how some systems in our body works together in situations to help us to have the ability to react and be alert of our surroundings such as being in danger or suffering from stress which is an important factor of many health problems. The two systems that I am referring to are the endocrine and nervous systems. they help to regulate our bodies back to our normal state to help to maintain healthy functioning.

Artificial electrical stimulation of the nervous system is one of the foundations of neurotechnology. However, the use of electrical currents to stimulate the nervous system presents several challenges. It is difficult to achieve selective stimulation of only the targeted neurons without activating neighboring neurons. Further, electrochemical reactions at the electrode-tissue interface may lead to electrode dissolution or tissue damage. As an alternative, magnetic stimulation can be used to...

A reflex is an action automatic action that our body make without us even having to think about. A reflex action is survuvial technique that humans have. Most refexes go completely unnoticed because they because they don’t involve a visible and sudden movement. If the reaction is exaggerated or absent it may indate damage to the central nervous system. Most reflexes don’t have to travel uto your brain to be processed , which is why they take place so quickly. A reflex action often...

The Relationship Between The Nervous System and The Endocrine System The cells and tissues in the body are delicate and easily disrupted. They will only be able to function well if all aspects of their chemical and physical environment is continuously adjusted to keep them stable and in equilibrium. The process in which several body systems work together to maintain the balanced environment is called homeostasis. The endocrine and nervous system work closely together to help maintain...

The building blocks of our body ' s neural information system are neurons. Each neuron is composed of dendrites, a cell body, axon with myelin sheath, and vesicles with neurotransmitters. The neuron receives information from sense receptors or from chemical messages from neighboring neurons via its dendrites, which pass the information to the cell body. The cell body fires an impulse, called the action potential, down the axon. The impulse is protected and sped along its way by the myelin...
