Peripheral Nervous System PD

What is the primary function of the peripheral nervous system?

• To process and interpret sensory information

• To control involuntary bodily functions like heart rate

• To act as an interface between the human body and its external environment

• To coordinate complex motor movements

Which of the following structures are part of the peripheral nervous system?

• Brain and spinal cord

• Nerves that thread through every part of the body, excluding the brain and spinal cord

• Only sensory receptors in the skin

• Only motor neurons controlling muscles

The peripheral nervous system is primarily divided into which two main divisions?

• Somatic and Autonomic

• Sympathetic and Parasympathetic

• Sensory (Afferent) and Motor (Efferent)

• Central and Peripheral

What is the main role of the sensory (afferent) division of the peripheral nervous system?

• To initiate physical responses to stimuli

• To enable the body to sense and perceive its surroundings

• To control internal organ functions

• To process information within the brain

Which system is a major component of the sensory division and is comprised of receptors along the exterior of the body?

• Autonomic nervous system

• Somatosensory system

• Central nervous system

• Motor nervous system

Why is the perception of pain considered a valuable biological response?

• It enhances our ability to enjoy pleasant sensations

• It helps us to protect ourselves from actively damaging stimuli

• It is a primary mechanism for learning new motor skills

• It indicates a healthy and active nervous system

Which of the following is NOT a method mentioned for categorizing sensory receptors?

• By the type of stimulus they detect

• By their location on the body

• By their structural complexity

• By their speed of signal transmission

Which type of sensory receptor responds to touch or pressure?

• Thermoreceptors

• Photoreceptors

• Mechanoreceptors

• Chemoreceptors

What kind of stimuli do nociceptors respond to?

• Light

• Temperature changes

• Damaging stimuli

• Specific chemicals

Receptors that respond to stimuli originating from outside the body are known as:

• Interoceptors

• Proprioceptors

• Exteroceptors

• Chemoreceptors
