Peripherial Nervous system

What is the primary function of the cerebrospinal fluid (CSF) as described in the text?

• To transmit nerve impulses to the brain

• To protect the brain from impacts and wash away toxins

• To supply nutrients to the brain tissue

• To regulate the temperature of the brain

Which of the following is NOT a component of the peripheral nervous system as mentioned in the text?

• Nerves or axons

• Clusters of cell bodies, called ganglia

• Arachnoid granulation

• Somatic nervous system

According to the text, why is the central nervous system more susceptible to damage than the peripheral nervous system?

• Because it is not protected by bone

• Because it is not protected by the blood-brain barrier

• Because it is more easily damaged but can regenerate more easily

• Because it is more exposed to infection and toxins

What does the somatic nervous system primarily control?

• Sensory input and motor commands for the torso and legs

• Motor commands to the muscles of the head and neck and sensory input from those regions

• The involuntary actions of the internal organs

• The production and circulation of cerebrospinal fluid

What does the autonomic nervous system control?

• Voluntary movements of the body

• Involuntary responses to regulate body aspects

• Sensations carried by nerves

• Movement of body parts consciously

What is the meaning of the Greek word "autonomia" from which the term autonomic nervous system is derived?

• Movement

• Sensation

• Independence

• Control

Which of the following is a function of the autonomic nervous system?

• Regulating voluntary muscle movements

• Controlling conscious sensations

• Regulating functions of internal organs

• Controlling the movement of limbs

What is the role of the somatic nervous system as described in the text?

• It controls involuntary responses.

• It regulates the functions of internal organs.

• It is responsible for conscious sensations and voluntary movements.

• It functions without conscious effort.

Which part of the nervous system is shown in Figure 16 as being responsible for movement control and sensory input?

• The autonomic nervous system

• The neuron

• The somatic nervous system

• The axon

What is the primary role of the sympathetic nervous system?

• To decrease heart rate and blood pressure

• To activate the body's "fight or flight" response

• To focus on digestion, growth, and cell division

• To send quick signals to all organs at the same time
