|
Nervous System
|
refers to the entire network of neurons in the body.
|
|
|
Glial Cells
|
Glial cells bind the neurons together and will also provide an insulating cover to the myelin sheath
|
|
|
Central Nervous System
|
Central – Brain and spinal cord – body’s “command central” – the nerve pathways connecting with the sense organs DO NOT pass the spinal cord. The spinal cord takes charge of simple, swift reflexes. The brain coordinates our body functions, and initiates our behaviors.
|
|
|
Peripheral Nervous System
|
All parts of the nervous system lying outside the central nervous system.
|
|
|
Autonomic Nervous System
|
sends messages back and forth between the CNS and the internal organs and glands.
|
|
|
Sympathetic Nervous System
|
sends messages to internal organs and glands that help us respond to stressful and emergency situations
|
|
|
Parasympathetic Nervous System
|
monitors the routine operations of the internal organs and returns the body to calmer functioning after arousal by the sympathetic division.
|
|
|
Somatic Nerous System
|
Brain’s communications link with the outside world. Carries sensory information to the CNS and also sends voluntary messages to body’s skeletal muscles
|
|
|
Sensory Nerous System
|
Connects the sense organs to brain (CNS)
|
|
|
Motor Nervous System
|
Connects the body’s skeletal muscles (muscles that control voluntary movement) to the brain (CNS)
|
|
|
This part of the nervous system would transfer pain information to the spinal cord when a person hits his/her thumb with a hammer
|
Peripheral Nervous System
|
|
|
What are the divisions of the peripheral nervous system
|
autonomic and somatic nervou systems
|
|
|
Interneurons
|
connect information between sensory and motor neurons
|
|
|
These things occur when the sympathetic nervous system is activated.
|
pupil dilation, respiration/heart rate increasing, slowed digestion, release of adrenaline
|
