What are the two main subdivisions of the nervous system?
Central Nervous System (CNS) and Peripheral Nervous System (PNS)
True or False: The Central Nervous System includes the brain and spinal cord.
True
Fill in the blank: The _______ Nervous System is responsible for voluntary control of body movements.
Somatic
What does the Autonomic Nervous System regulate?
Involuntary bodily functions, such as heart rate and digestion.
Multiple Choice: Which subdivision of the nervous system is responsible for the ‘fight or flight’ response?
Sympathetic Nervous System
What are the two branches of the Autonomic Nervous System?
Sympathetic and Parasympathetic Nervous Systems
True or False: The Parasympathetic Nervous System conserves energy and promotes ‘rest and digest’ functions.
True
Short Answer: What is the primary function of the Somatic Nervous System?
To control voluntary movements of skeletal muscles.
Fill in the blank: The _______ Nervous System connects the CNS to the limbs and organs.
Peripheral
Multiple Choice: Which type of response is associated with the conscious control of actions?
Voluntary Response
What is an example of an unconscious response?
Reflex actions, such as pulling your hand away from a hot surface.
True or False: Reflex actions involve the brain for processing.
False
Short Answer: What is the role of sensory neurons?
To transmit sensory information to the CNS.
Fill in the blank: The _______ Nervous System is primarily responsible for the body’s response to stress.
Sympathetic
Multiple Choice: Which part of the nervous system is primarily involved in homeostasis?
Autonomic Nervous System
What is the main difference between conscious and unconscious responses?
Conscious responses are voluntary and involve awareness; unconscious responses are automatic and occur without awareness.
True or False: The Somatic Nervous System can influence involuntary actions.
False
Short Answer: What type of neurons carry signals away from the CNS?
Motor neurons
Fill in the blank: The _______ Nervous System is involved in the ‘rest and digest’ functions.
Parasympathetic
Multiple Choice: Which nervous system subdivision primarily deals with reflex arcs?
Peripheral Nervous System
What is a reflex arc?
A neural pathway that controls a reflex action.
True or False: The Central Nervous System contains both afferent and efferent pathways.
True
Short Answer: Name one effect of the Sympathetic Nervous System activation.
Increased heart rate.
Fill in the blank: The _______ Nervous System is responsible for carrying sensory information to the CNS.
Afferent
Multiple Choice: Which type of response is typically faster, conscious or unconscious?
Unconscious Response
What is the function of interneurons?
To connect sensory and motor neurons within the CNS.
True or False: The Autonomic Nervous System operates independently of conscious control.
True
Short Answer: Which part of the nervous system is responsible for the integration of sensory information?
Central Nervous System
Fill in the blank: The _______ Nervous System helps to prepare the body for stressful situations.
Sympathetic
Multiple Choice: Which nervous system component is responsible for voluntary muscle movements?
Somatic Nervous System
What type of response is a knee-jerk reflex?
Unconscious Response
