The brain is an amazing three-pound organ that controls all functions of the body, interprets information from the outside world, and embodies the essence of the mind and soul. Intelligence, creativity, emotion, and memory are a few of the many things governed by the brain.
Anatomy and physiology of the nervous system
Nervous system , organized group of cells specialized for the conduction of electrochemical stimuli from sensory receptors through a network to the site at which a response occurs. All living organisms are able to detect changes within themselves and in their environments. Changes in the external environment include those of light , temperature , sound , motion, and odour , while changes in the internal environment include those in the position of the head and limbs as well as in the internal organs. Once detected, these internal and external changes must be analyzed and acted upon in order to survive. As life on Earth evolved and the environment became more complex, the survival of organisms depended upon how well they could respond to changes in their surroundings. One factor necessary for survival was a speedy reaction or response. Since communication from one cell to another by chemical means was too slow to be adequate for survival, a system evolved that allowed for faster reaction.
The nervous system is a network of cells called neurons that coordinate actions and transmit signals between different parts of the body. The nervous system is an organ system that coordinates voluntary and involuntary actions and responses by transmitting signals between different parts of our bodies. Central to the functioning of the nervous system is an extensive network of specialized cells called neurons. Neurons feature many thin projecting fibers called axons, which penetrate deep into tissues. They are able to communicate with other cells by chemical or electrical means at synapses. Neuronal function is supported by neuroglia, specialized cells which provide nutrition, mechanical support, and protection. Major elements in neuron-to-neuron communication : Electrical impulses travel along the axon of a neuron.
Central nervous system
The brain is a fascinating and complex organ. It is responsible for senses, movement and control, emotions and feelings, language and communication, thinking and memory. Research of the brain and understanding the inner workings of the brain will help us to learn about the mechanisms of certain neurological conditions, including hydrocephalus. Increasing our own knowledge of the brain helps us understand our own bodies better and helps us have informed conversations with our doctors, be it as a patient or a caregiver. To celebrate BAW we present a two-part blog to increase our understanding of the brain and how the brain is impacted by hydrocephalus. We hope you enjoy these blogs and find them both informative and useful.
In biology , the nervous system is a highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The nervous system detects environmental changes that impact the body, then works in tandem with the endocrine system to respond to such events. The CNS consists of the brain and spinal cord.
The nervous system is a complex network of nerves and nerve cells neurons that carry signals or messages to and from the brain and spinal cord to different parts of the body. It is made up of the central nervous system and the peripheral nervous system. The central nervous system CNS is made up of the brain and spinal cord. The brain controls most body functions, including awareness, movements, sensations, thoughts, speech and memory. The spinal cord is connected to the brain at the brain stem and is covered by the vertebrae of the spine.
The central nervous system CNS is the part of the nervous system consisting primarily of the brain and spinal cord. The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric animals —i. It consists of a large nerve running from the anterior to the posterior, with the anterior end is enlarged into the brain.
Конечно, - чуть слышно сказала. - Танкадо подумал, что раз мы приостановили действие его страхового полиса, то можем приостановить и его. Постепенно она начала понимать. Время сердечного приступа настолько устраивало АНБ, что Танкадо сразу понял, чьих это рук дело, и в последние мгновения своей жизни инстинктивно подумал о мести.
Вот. - Она едва заметно подмигнула. - В этом все и. - Мидж… - Доброй ночи, Чед.
Мы погибли, - прошептала Мидж.
Беккер мрачно кивнул невидимому голосу. Замечательно. Он опустил шторку иллюминатора и попытался вздремнуть. Но мысли о Сьюзан не выходили из головы. ГЛАВА 3 Вольво Сьюзан замер в тени высоченного четырехметрового забора с протянутой поверху колючей проволокой.
Его темные глаза выжидающе смотрели на Сьюзан. - Мисс Флетчер, как вы полагаете, если это не ключ, то почему Танкадо обязательно хотел его отдать. Если он знал, что мы его ликвидируем, то естественно было бы ожидать, что он накажет нас, допустив исчезновение кольца. В разговор вмешался новый участник.
