Central Nervous System Research Paper

The nervous system is one of the body’s complex functions that contain a network of cells and nerves that transmit signals from the brain and spinal cord to different areas of the body. It is categorized into two groups; the central nervous system which is made up of the brain and spinal cord, and the peripheral nervous system which contains the body’s nervous tissue and is where neurologic responses occur. Homeostasis, which is the process in which thermoregulation is maintained, also happens in this area.

The nervous system in general is quite a complex and sophisticated system which is responsible for regulating and coordinating the body’s activities. The central nervous system consists of the brain and spinal cord, mainly responsible for gathering information and responds to any changes within environment.

The nervous system is made of two systems which consist of the central nervous system and the peripheral nervous system. The central nervous system is composed of the brain, spinal cord, and the nerves in the body. The peripheral nervous system is composed of nerves and a bundle of nerve cells called ganglia, which is located on the outside of the spinal cord and the brain. The nervous system is responsible for controlling and communicating with other parts in the body to maintain blood pressure, breathing, and other essential functions to carry out an ordinary lifestyle (Zimmermann, K.A., 11 March

Each individual nerve is made up of: afferent nerves and efferent nerves where afferent nerves transmit impulses towards the nervous system from different parts of the body and efferent nerves transmit impulses away from the nervous system to the different parts of the body. The autonomic nervous system is another type of PNS responsible for involuntary actions like movement of heart, lungs, etc.

The nervous system is a chain of interconnected nerve fibers which is constructed by the central nervous system and Peripheral nervous system. The job of the nervous system is to send messages from the brain and spinal cord to different parts of the body.

The central nervous system consists of the brain and spinal cord. The brain takes information from the senses and processes it and it also makes decision sand sends commands to the body. The spinal cord carries information to and from away the brain. The peripheral system, on the other hand, is the system that allows communication between the central nervous system with the sensory systems. It also makes it possible for the brain and spinal cord to control muscles and

The nervous system is responsible for muscle movement. The nervous system consists of central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is constitute of the brain and the spinal cord, and PNS is a network of nerves that runs throughout the body. The brain sends electrical signals to the CNS, and they are disbursed the PNS to produce body movement (Acrobatiq, 2014). Then, these signals travel back from the PNS to CNS to coordinate the next course of action of the body (Acrobatiq, 2014). The motor cortex section in the cerebrum sends messages to the muscles to coordinate accurate movement. Also, its control balance posture during the exercise and movement. The muscles instructed by the impulses from the cerebrum move in the given direction. They relax and contract according to the message relayed by the motor neurons.

The central nervous system and the peripheral nervous system is the 2 main systems. The central nervous system is made up of the spinal cord and brain which is in the dorsal body cavity. It is the integrating and control center of the nervous system. Also the CNS helps with sensory input, dictates motor outputs based on reflexes and lastly past and current experiences.

When cells “fire,” this is called exocytosis (Ingersoll, year). A neuron fires and sends neurotransmitters into the synaptic cleft. Some of them will attach to receptors on another neuron. This attachment is labeled a “first-messenger effect”. This first-messenger effect can either be excitatory or inhibitory. The neurotransmitter that binds at an excitatory synapse can trigger an electrical impulse, and this impulse is that is transported through the receptor and into the neuron. If the signal is strong enough to

Activation of a motor neuron: The motor neuron now transmits nerve impulse to an effector.

The peripheral nervous system (PNS) is connected directly to the central nervous system, and consists of neurons and nerves that send information back and forth the CNS. Furthermore, the peripheral nervous system can be divided into two sections, the sensory nervous system and the motor nervous system. The Sensory The sensory nervous system is in charge of transmitting data from a variety of internal organs or from external stimuli to the central nervous system using sensory nervous cells. On the other hand, the cells of the motor nervous system (motor neurons), take the impulse from the CNS to effectors, which include glands and muscles. In addition, the motor nervous system can be further divided into the somatic nervous system, controls voluntary actions of the skeletal muscle and external sensory organs, whilst the autonomic nervous system operates

The body has two major communication systems, one being the endocrine system and the other being the nervous system. Both of these systems are used to regulate biopsychological functions. The nervous system is broken up into two different parts, the central nervous system and the peripheral nervous system. Although the nervous system as a whole has one main communication system which is the brain. However the nervous system made up of a system of neurons. A neuron is a specialized cell that transmits information.

There are five steps in a reflex arc, which allows for impulse actions to occur called reflexes. The first step is when the receptor senses a stimulant. The next step occurs when the sensory neuron transmits nerves impulses to the spinal cord from the nerve and root. The third phase is when the sensory neuron goes through a neuronal junction with an interneuron; this occurs in the spinal cord. The fourth step is when the interneuron goes through neuronal junction with a motor neuron. Then the last step is when the motor neuron impulses through the spinal nerve and root to an effector structure. In summary, the receptor senses the action, then the sensory neuron transports the stimulus near the spinal cord, then the interneuron spreads the urge

The nervous system is divided into two major sections: There is the central nervous system and the peripheral nervous system.

The human nervous system is divided into two parts, the central nervous system and the peripheral nervous system. The central nervous system, CNS, is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from CNS, to transmit information to your limbs and organs for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain.
