brain & spinal cord
What cavity does it occupy? 
dorsal body cavity
Which of the 3 functions, sensory input, integration or motor input, is the CNS responsible for?  
It is responsible for all of them]]> 2018-01-30 15:44:16 UTC https://padlet.com/denpan929/yb6vmqy71856/wish/226143340 Peripheral nervous System (PNS) denpan929 https://padlet.com/denpan929/yb6vmqy71856/wish/226145332 Where is it in relation to the CNS? 
outside the cns
The PNS consists mainly of spinal and cranial nerves 
What are spinal nerves? 
carry impulses to send messages to spinal cord
What are cranial nerves ? 
carry impulses to and from the brain

-It is made up of the somatic and visceral sensory nerve fibers 
What are somatic sensory fibers? 
convey impulses from the skin to skeletal muscles and joints
What are visceral sensory fibers? 
transmit impulses from visceral organs]]> 2018-01-30 15:50:09 UTC https://padlet.com/denpan929/yb6vmqy71856/wish/226147480 Motor division denpan929 https://padlet.com/denpan929/yb6vmqy71856/wish/226148057 transmits signal from the CNS to the effector organs. In other words they bring about a motor response. 
What are 2 examples of effector organs? 
muscles and glands]]> 2018-01-30 15:50:56 UTC https://padlet.com/denpan929/yb6vmqy71856/wish/226148057 Somatic nervous system denpan929 https://padlet.com/denpan929/yb6vmqy71856/wish/226152037 composed of motor nerve fibers that control skeletal muscles 
Voluntary or involuntary? 
voluntary]]> 2018-01-30 15:56:49 UTC https://padlet.com/denpan929/yb6vmqy71856/wish/226152037 Autonomic Nervous System (ANS) denpan929 https://padlet.com/denpan929/yb6vmqy71856/wish/226152852 composed of visceral motor nerve 
which regulate the activity of smooth muscles, cardiac muscles and glands
Voluntary or involuntary 
involuntary
Has 2 functional subdivisions which work in opposition of each other. Whatever one stimulates the other inhibits.
