Describe the structure of the Central Nervous System
The central nervous system is usually accountable for incorporating sensory details along
with retaliating appropriately. However, it usually entail two elements that the spinal cord and
the brain which typically works together to send messages between one another. The spinal cord
normally represents the passage for signals between the brain and the rest of the body.
Furthermore, it manages simple musculoskeletal reflexes with no intake from the brain. On the
other hand, the brain is answerable for amalgamating most sensory details together with
synchronizing the operations of the body both sensibly and insensibly (Bernard-Marissal, Chrast,
and Schneider, 2018).
The brain happens to be the most complex organ since is it’s the central control module
of the body and synchronizes all the body operations. From bodily passage to the organic process
of hormones, the generation of memories together with the perception of feelings.
Figure 1 (Shen and Zipes, 2014)
The spinal cord usually conveys details amidst the brain and the body together with the
other escapades. It is however linked to a portion of the brain known as brainstem which passes
via the spinal canal ( (Zipes 2014)). The cranial nerves usually depart the brainstem while the
nerve roots leave the spinal cord to both sides of the body.
Describe the structure of the Sensory connector and motor neurons.

BIOLOGY 3
The sensory neuron usually alerts the rest of the brain concerning the external and
internal surrounding by handling details which is extracted from one among the five senses
(Shen and Zipes, 2014). Accordingly, they usually receive data from the sense organs to the
brain and the spinal cord. They have elongated dendrites and tiny axons.
Figure 2 (Shen and Zipes, 2014)
The motor neurons typically convey the electrical instincts off from the brain and the
spinal cord to the organs and muscles within the body. It has short dendrites and long axons

You should describe how nerve impulses are transmitted
The nerve impulses are the electrical current which moves via the nerve cell that is controlled to
the nervous system that will ultimately generate a report. The report is however handled within
the brain for specific reaction (Scott, Cluff, Lowrey and Takei, 2015). The conveyance of the
nerve impulse usually begins with energizing of a nerve cell by modifying the voltage across the
