The nervous system is divided into what 2 systems?
Central Nervous system (CNS)
Peripheral Nervous system (PNS)
CNS is made up of…
Brain and Spinal Cord
PNS is made up of…
Nerves that enter and exit the CNS
In terms of function, the nervous system can be divided into…
The somatic and autonomic nervous system
What does the Somatic Nervous system control?
Voluntary control
What does the Autonomic Nervous system control?
Self regulates by means of built in feed back system.
How does the Somatic and Autonomic systems differ from each other?
Anatomy, functional, and pharmacology
More specifically, what are the functions of the Somatic System?
Receives information on touch, heat, pain and position of eyes, ears, nose, and joints.
The conscious actions it produces originates from the cerebral cortex and mediate body movements.
More specifically, what are the functions of the Autonomic System?
Operates through unconscious control through centers of the hypothalamus and brainstem. Smooth muscles and glands are the means of a response.
The ANS is divided into what 2 divisions?
Sympathetic and Parasympathetic
The autonomic nervous system controls a majority of the body’s automatic_______ –––––––
homeostatic responses such as moment to moment control of blood pressure, heart rate, and blood flow
The sympathetic and parasympathetic divisions work together to keep…
Homeostatic responses, working in harmony to balance body processes.
Fight or flight
sympathetic (adrenergic)
rest and digest
parasympathetic (cholinergic)
Agonist
