Bill Nye the Nervous Guy!

Hey guys! Im Bill, and I am going to talk to you about the nervous system! Let's get right into it! The nervous system is the system of your body that coordinates actions and transmits signals to all parts of your body. Without the nervous system, we wouldn't feel pain. Your nerve cords are reaction to actions, while transmitting signals that is telling your body that you are in pain. Vertebrates are made up of two main parts of the nervous system, the Central Nervous System, and the Peripheral Nervous System. The Central Nervous System is made up of the brain and spinal cord, and the Peripheral Nervous System is made up of mostly nerves, “which are enclosed bundles of the long fibers or axons, that connect the CNS to every other part of the body”. In total, the nervous system makes up the brain, spinal cord, sensory organs, then we get into nerve fibers, which branch of and consist of the neck and arms, torso, legs, skeletal muscles and internal organs.

Nerves that transmit signals from the body to the Central Nervous System are called sensory. Some nerves serve both functions and are called mixed nerves. “The PNS is divided into a) Somatic b) Autonomic nervous system c) The enteric nervous system. Somatic nerves mediate voluntary movement.” Nerves that exit through cranium are called cranial and other nerves that exit through the spinal cord are called spinal nerves. Hopefully your are getting a sense of how the nervous system works, an action has happened to your body and the nerve cords are sensing it while transmitting signals all over your body to send signals that you are in pain. This is a very complex system and includes the brain, which goes very in depth on how the nervous system is connected to your

Factors Leading to Joseph's Dehydration: A Case Study

1022 Words | 5 Pages

Neurons transmit information to each other and to muscles, organs and glands. The nerve impulse is sent from the axon of one neuron to the dendrite of another neuron. The neuromuscular junction as labeled in Part A of this assignment, shows that there is a space between the axon of a neuron and the motor plate of the muscle cell. The two parts do not actually touch each other. When the football player’s brain sends a message to move during the game, the nerve impulse is sent from neuron to muscle cell.

The ganglia of neighboring segments are linked by connectives, while the hemi-ganglia are connected by commissures. Overall, the structure of this nervous system appears as a ladder-like chain consisting of a brain, two connectives, and a ventral nerve cord. Because lobsters lack a cerebral cortex, they rely on this complex nervous system to translate pain impulses into the sensation of pain

Cranial Nerves Lab Report

1888 Words | 8 Pages

There are twelve pairs of cranial nerves. Each pair has a name and a Roman numeral assigned to it. These nerves are developed in utero during gestation. These nerves leave the brain and pass through the foramina of the skull in order to travel to the sensory organs or to the muscles of the head and neck that they innervate. Cranial nerves may serve motor functions, sensory functions, or both.

Frog Heart Lab Report

Towards the end of the 19th century, one of the great mysteries challenging scientists was how the billions of nerve cells that make up the human nervous system communicate with each other and how the stimulation of a nerve was transmitted to the effector organ from the nerve ending. Most neurophysiologists thought that it occurred through direct transmission of the stimulation wave from the nerve cell to the effector organ or to another nerve cell; many of them defending the idea that signaling across synapses is electrical, just like the propagation wave along the axon during an action potential. However, there was ample evidence to argue against such a simple picture of neuronal communication. Scientists had observed that there was a unidirectional

Summary: The Two Branches Of The ANS System

115 Words | 1 Pages

The two branches of the ANS system are SNS which stands for sympathetic nervous system and the PNS which stands for parasympathetic nervous system. The SNS triggers the “fight or flight” response, it originated in the spinal cord. SNS prepares the body to put our energy and to protect it from effects of injury. SNS shuts the gut down, speeds up the heart, increases blood pressure, dilates pupils, makes more glucose available in the blood for energy. PNS is sometimes referred to as the “rest and digest” system.

Pituitary Cancer An understanding of the nervous system, specifically of the pituitary gland, is required to understand cancers found in the system. The nervous system is essential to live, for its functions include memory storage, motor function, sensory processing, regulation of body functions, and thought processes. The nervous system is anatomically divided into the central and peripheral nervous systems. The peripheral nervous system consists of the nerves found throughout the body while the brain and spinal cord makes up the central system.

These nuclei are small collections of cholinergic nerve cells in dorso-lateral reticular formation. The neuron of these two nuclei seems to be intermingled with each other.

An Essay On The Muscular System

723 Words | 3 Pages

The muscular system is very important for everyday life. Without it we wouldn't be able to carry out everyday tasks such as writing this paper or tying our shoes or anything. This system also helps us distribute wastes when our body doesn’t need them anymore, which is important because if the wastes build up the toxins will enter your system the wrong way and it will harm you eventuly. This system interacts with the many other systems but the main two are the nervous system and the digestive system. The nervous system is what controls the brain and the brain tells us to move certain parts of our bodies without us knowing it, this is how our involuntary muscles move.
