The nervous system consists of the central nervous system, which consists of the spinal
cord and the brain. After that, there are the peripheral nervous and autonomic nervous
system. Under the autonomic nervous system are two other systems called the
parasympathetic and the symphatic nervous system. Both these nervous systems work
antagonistically towards each other; almost as opposites. The parasympathetic nervous
system releases neurotransmitters acetylcholine, whereas the symphatic nervous system
releases the neurotransmitters adrenaline. There are also two other nervous systems called
symphatic and autonomic nervous systems. The somatic nervous system includes with
working with skeletal muscles stimulated by smell, noise, taste, touch, pain, and
temperature. Whereas the autonomic nervous system is involved in involuntary smooth
muscles, which are stimulated by blood pressure, blood concentration and ph. Every one of
the nerve cells in your body are part of the nervous system. Humans interact with the
external environment via our nervous system, which also regulates several internal bodily
systems. The nervous system receives data from our senses, interprets it, and causes
responses, including such enabling your muscles to contract or helping you experience pain.
According to their locations throughout the body, the nervous system is divided into two
halves, the central nervous system, and the peripheral nervous system. The nerves in the
brain and spinal cord are part of the central nervous system. It is securely enclosed inside
the spinal canal and cranium. The peripheral nervous system includes almost every nerve in
the organism. The voluntary and involuntary nerve systems can also be distinguished
depending on the region of the organism they are located. The somatic nervous system, also
known as the voluntary nervous system, regulates all the bodily movements that we are
cognizant of and have direct awareness over. The bodily functions that humans are unable
to consciously control is controlled by the involuntary nervous system. It governs like
breathing, circulation, and metabolic functions continually. It accomplishes this by taking in
brain impulses and transmitting these to the body. It may deliver messages another way, as
from central nervous system, telling your brain, for instance, how rapidly your heart is
pounding and even how heavy your bladder is. The body’s natural internal systems may
