Nervous system and its cells Physical education essay
A human's nervous system consists of the brain, spinal cord, sensory organs and all the neurons that serve as communication channels between the various organs of the body. It is: 1. Introduction. The discovery of the nervous system dates back to the time when the ancient Greek physician-philosophers Alcmaeon, Praxagoras, Herophilus 1,2 and Erasistratus Herophilus c335-cC were able to understand the structure of the brain and nerves, particularly by dissecting human cadavers. to describe. and to realize this motorically, brain tumors can cause epilepsy. Epilepsy can also be caused by the way blood vessels form in the brain. People with blood vessel disorders such as arteriovenous malformations and cavernous malformations may experience seizures. And in adults older than that, stroke is a leading cause of epilepsy. Diagram of the breakdown of the nervous system The autonomic nervous system ANS is a functional part of the nervous system that controls involuntary actions of muscles, glands, and internal organs, such as bowel movements. Together with the endocrine glands, the ANS influences important bodily functions without the direct involvement of Physical Education Topics and Examples to get you started: The Benefits of Physical Education in Schools. The role of physical education in promoting mental health. The impact of physical education on academic performance. The importance of physical education for children with disabilities. The spinal cord is a long, tube-like band of tissue. It connects your brain to your lower back. Your spinal cord transports nerve signals from your brain to your body and vice versa. These nerve signals help you feel sensations and move your body. Any damage to your spinal cord can affect your movement or function. The proper function of neurons depends on specialized glial cells. All nervous systems of all animal species have seven basic types of functional cells: Sensory neurons: These neurons tell the rest of the brain about the external and internal environment. Motor neurons and other output neurons: Motor neurons contract muscles and the autonomic nervous system appears to play an important role in how an organism responds to oxidative stress, as it is linked to a decrease in oxidative stress caused by physical exertion. The departments of the autonomic nervous system include the internal organs, skin and muscles and control their function by producing and secreting Parkinson's disease. Parkinson's disease is a movement disorder of the nervous system that gets worse over time. As nerve cell neurons in parts of the brain weaken, become damaged, or die, people may notice problems with movement, tremors, stiffness in the limbs or trunk of the body, or imbalance. As symptoms progress, people may have this too. The nervous system is a specialized system in animals. This system helps in the coordination of voluntary and involuntary actions, reflex actions in our body. The nervous system consists of nerve cells, neurons. They send messages in the form of electrical impulses through neurons and transmit them to our senses. The central system is the main command center for the body and consists of the brain and spinal cord. The peripheral nervous system consists of a network of nerves that connect the rest. 1 Introduction. The intrinsic cardiac nervous system ICNS is also called the 'little brain' of the heart. It provides continuous adjustments to the mechanical and electrical activity of the heart and exists,
