Write an essay describing the neuron function.
The nervous system is made of the central nervous system which includes:
- The brain
- Spinal cord
It is also made up of the peripheral nervous system which is consisted of the sensory and motor neurons and lastly the autonomic nervous system which helps in modifying the body processes such as the digestion and heart rate for the body to function properly. [1]
Neurons are excitable cells that help in processing and transmitting information. Even though they are quite small, they are very complex structures.
The communication process by neurons is divided into four parts. Firstly, the neuron will receive information from the external environment or other neurons. Secondly, the neuron will process the information from all of its input and determine or not to send an output signal depending on the situation. Thirdly, the neuron will transmit the signal along the length at a fast speed. Lastly the neuron will convert the electrical signal to a chemical one and hand it over to another neuron or to a muscle or gland. …show more content…
The refractory period is when the nerve or muscle cell fires during which the cell can’t respond to stimulation not until the resting potential is re-established. This process is called the refractory period. The first part of the refractory period this is called the absolute refractory period. It reaches the start of the action potential until the K+ begins to shut. During this process, the sodium channels are active, so the membrane will not respond to the stimuli. The second part of this process is called the relative refractory period and will precede until the membrane ends up in a resting state. The sodium channels will deactivate while the potential at the same time will change. Lastly, the only way to open these channels is to have a high stimulus.
