Know differences between the SNS and ANS

The Somatic Nervous System (SNS) is?

Consciously controlled systems.

Autonomic Nervous System (ANS)

Nonconscious controlled systems.

What are Two consciousness classifications?

Somatic Nervous System (SNS)

Autonomic Nervous System (ANS)

The function of the ANS is to?

Maintain homeostasis

Somatic motor units Have?

One motor neuron that comes off the CNS to the muscle or glands

Autonomic motor units Have?

Two motor neurons that come off the CNS to the muscle or glands

The ANS can be subdivided functionally into two divisions, which are?

The Parasympathetic Division

The Sympathetic Division

The definition of the Parasympathetic Division

Promotes the “rest and digest” processes; heart rate and blood pressure lower, gastrointestinal peristalsis/digestion restarts,etc

The definition of the Sympathetic Division

Regulates the state of overall elevated activity and attention: the “fight or flight” response. In this process, blood pressure and heart rate increase, glycogenolysis ensues, gastrointestinal peristalsis ceases, etc

(SNS) Somatic sensory neurons are?

Stimuli induced (i.e., special senses)

(SNS) somatic motor neuron are?

Voluntary initiation of skeletal muscle movement

Visceral Sensory are?

Sensory system that initiates response of ANS

(ANS)Visceral Sensory are?

Sensory system that initiates response of ANS

(ANS)Autonomic motor are?

Involuntary initiation of smooth and cardiac muscles or glands
