The system is what makes up our body, it's the foremost sophisticated of the various systems within the body, and it's conjointly a network of nerve cells and fibres that transmits nerve impulses between components of the body. This essay will explore the structure and functions of the system similarly as well as looking in depth at the neurons and how they communicate
The system is split into two components, the central nervous system- which incorporates the brain and also the spinal cord. The structure of this is often secured by the bone and cushioned from injury by spinal fluid.
The brain is split into five components, neural structure – is the largest part of the brain. It’s the centre for thought and intelligence. it's divided into right …show more content…
The main divisions of the Peripheral Nervous System are the autonomic nervous system — that controls the automated functions of the body: the heart, smooth muscle (organs) and glands. It’s divided into the “fight-or-flight” system and also the “resting and digesting" system. The somatic nervous system — that permits us to consciously or voluntarily control our skeletal muscles. The somatic nervous system contains 12 cranial nerves and 31 spinal nerves. Nerves — that are created of special cells referred to as neurons. Neurons are comprised of a nerve fibre, a cell body and an axone. Impulses travel to the nerve fibre into the cell body so onto the axone. A special sheath referred to as myelin, that will increase the the conductivity of the neuron, covers some …show more content…
Neurons are cells that receive and transmit signals. There are three styles of neurons, Sensory neurons: These neurons are referred to as afferent neurons. Their function is to receive initial stimuli from sense organs — eyes, ears, tongue, skin, and nose — similarly as by impulses generated among the body in response to changes that are necessary to maintain homeostasis.
.
Interneurons: These styles of neurons are referred to connector neuronsor association neurons. What they do is “read” impulses received from sensory neurons. Interneurons are found within the spinal cord or brain.
When an interneuron receives an impulse from a sensory neuron, the interneuron determines what response should be generated. If a response is needed, the interneuron passes the impulse on to motor neurons.
Motor neurons: These neurons are referred to as efferent neurons, and their function is to stimulate effector cells. Once the motor neurons receive an indication from the interneurons, the motor neurons work to stimulate a sway. Once the effector cells are they generate
