Nervous System 1 Flashcards
The nervous system is a network of what?
Fibres
Spanning the body, co-ordinating a range of voluntary and involuntary actions
Which system does the nervous system work alongside to maintain homeostasis?
Endocrine
What is the CNS?
Central Nervous System
Made up of the brain and spinal cord
What is the PNS?
Peripheral nervous system (everything else)
What does the somatic nervous system control?
Voluntary muscles and transmits sensory information to the CNS
Which neutron function processes sensory information, analyses, stores and makes decisions?
Integration
Which neuron function detects internal and external environmental changes?
Sensory
Which neuron function produces a response to sensory information to effect change?
Motor
Study the difference between CNS and PNS
CNS - brain and spinal cord
PNS - somatic and autonomic nervous systems
Automatic further splits into sympathetic and parasympathetic
Which nervous system controls voluntary movements
Somatic
Which nervous system controls involuntary movements
Autonomic
Name the specific body location of the sympathetic nervous system
Thoracic-lumbar innervation
Name the specific body location of the parasympathetic nervous system
Cranio-sacral innervation
How is the enteric nervous system linked to the CNS?
Via the sympathetic and parasympathetic nerve fibres (vagus nerve)
Define action potential
A nerve impulse
