Key Points
Key Points: Human Neural System
- The human neural system is divided into two parts - CNS (Central Neural System) and PNS (Peripheral Neural System).
- CNS - consists of the brain and spinal cord; it is responsible for information processing and control.
- PNS - consists of all nerves associated with the CNS. Afferent fibres carry impulses from organs/tissues → CNS; Efferent fibres carry impulses from CNS → organs/tissues.
- PNS is divided into the Somatic neural system (relays impulses from the CNS to skeletal muscles) and the Autonomic neural system (controls involuntary organs and smooth muscles).
- The autonomic neural system is further divided into the sympathetic and Parasympathetic neural systems.
- Visceral nervous system - part of PNS; network of nerves, fibres, ganglia and plexuses that transmit impulses between CNS and the viscera (internal organs).
