Neural Control and Coordination Flashcards
What are the two main parts of the Central Nervous System (CNS)?
The brain and the spinal cord.
True or False: The CNS is responsible for processing and transmitting information throughout the body.
True.
Fill in the blank: The _____ is the largest part of the brain.
cerebrum.
What is the primary function of the spinal cord?
To transmit signals between the brain and the rest of the body.
Which part of the brain is responsible for coordinating voluntary movements?
Cerebellum.
What is the role of the brainstem?
It controls basic life functions such as breathing, heartbeat, and blood pressure.
True or False: The CNS includes all the nerves outside the brain and spinal cord.
False.
What are the protective layers surrounding the CNS called?
Meninges.
Which structure is responsible for the production of cerebrospinal fluid?
Choroid plexus.
What is the function of the thalamus?
To relay sensory information to the cerebral cortex.
Fill in the blank: The _____ lobe is primarily responsible for vision.
occipital.
What is the function of the hypothalamus?
To regulate homeostasis, including temperature and hunger.
True or False: The corpus callosum connects the left and right hemispheres of the brain.
True.
What type of cells provide support and protection for neurons in the CNS?
Glial cells.
What is the primary function of the frontal lobe?
To manage executive functions such as decision-making and problem-solving.
Fill in the blank: The _____ is involved in emotional responses and memory.
limbic system.
What is the role of the dorsal root in the spinal cord?
To carry sensory information to the CNS.
Which part of the CNS is primarily involved in reflex actions?
Spinal cord.
True or False: The CNS can regenerate damaged neurons.
False.
What are the main neurotransmitters involved in CNS signaling?
Dopamine, serotonin, and norepinephrine.
Fill in the blank: The _____ is a bundle of nerves that runs down the spine.
spinal cord.
What is the function of the medulla oblongata?
To regulate autonomic functions such as heart rate and respiration.
What is the significance of the blood-brain barrier?
It protects the brain from harmful substances in the bloodstream.
Which brain structure is primarily involved in balance and coordination?
Cerebellum.
True or False: The CNS is responsible for voluntary and involuntary actions.
True.
What is the primary role of sensory neurons?
To transmit sensory information to the CNS.
