The autonomic nervous system has 3 subdivisions, they are:

• Parasympathetic, enteric and sympathetic

• Somatic, sympathetic and enteric

• Parasympathetic, sympathetic and central

• Somatic, autonomic and enteric

Which of the following indicate that the body is in a heighted state of arousal?

• Increased heart rate, decreased saliva

• Increased lung capacity, decreased blood pressure

• Increased heart rate, dilated pupils

• Decreased saliva, dilated pupils

What is the primary role of the central nervous system?

• Coordinating all of the bodies conscious and unconscious activities

• To regulate, coordinate and control the major functions of the body

• Relaying messages to and from the brain

• Regulating automatic involuntary operations

Which type of neurons transmit messages form the body to the CNS?

• Peripheral

• Interneuron

• Motor

• Sensory

The somatic nervous system controls _______ muscle movement. This does not include non-skeletal ______ such as the heart or lungs.

• skeletal, autonomic

• skeletal, muscle

• attention, awareness, awareness

• awareness, attention, awareness

• sensory, input, awareness

• intentional, unintentional, awareness

A spinal reflex (reflex arc) differs from a standard reflex because....

• Nerve impulses are passed along efferent pathways to the interneuron

• Nerve impulses sent to the brain control an automatic response

• Nerve impulses are sent to the interneuron and the brain

• Nerve impulses are sent to the interneuron for processing

What is the role of the sympathetic nervous system?

• To create a sense of arousal to prepare the body to deal with an emergency

• To calm the body and restore a balanced state

• To initiate the flight, fight and flee response

• To prepare the body to deal with future stressor

Which of the following physiological symptoms indicate the parasympathetic nervous system is dominant?

• Decreased breathing rate, dilated pupils, relaxed baldder

• Decreased blood pressure, increased heart rate, constricted pupils

• Decreased heart rate, increased perspiration, slowed digestion

• Decreased respiration, contracted bladder, stimulated saliva

When the sympathetic nervous system is dominant the parasympathetic nervous system is....

• Not activated

• Dominant

• Dormant

• Not dominant
