Overview of the Nervous System[edit | edit source]
The nervous system can be divided into 3 significant parts.
These are
- Autonomic Nervous System (ANS)
- Peripheral Nervous System (PNS)
- Central Nervous System (CNS)
1. Autonomic Nervous System
The ANS's main role is to innervate the internal and glandular organs. The peripheral component is defined in terms of the enteric, sympathetic, and parasympathetic systems.
2. Peripheral Nervous System
The PNS consists of nerve trunks that are formed from both afferent axons which conduct sensory information to the spinal cord, and efferent fibres which transmit impulses primarily to muscles. If these a particular nerve is damaged, then there is resulting weakness to the muscle it supplies as well as sensory loss from the region it conveys information from.
The peripheral nerves connect with the spinal cord through foramina in the vertebra of the spine, or with the brain through foramina in the skull.
3. Central Nervous System
