Nervous System Overview (AI Generated) Flashcards
(48 cards)
What is the primary function of the nervous system?
To coordinate and control body activities by transmitting signals between different parts of the body.
True or False: The nervous system is divided into the central nervous system and the peripheral nervous system.
True
What are the two main components of the central nervous system (CNS)?
The brain and the spinal cord.
Fill in the blank: The _______ nervous system includes all the nerves outside the CNS.
Peripheral
What type of cells are the basic building blocks of the nervous system?
Neurons
What is the role of glial cells?
To support and protect neurons.
Multiple Choice: Which part of the neuron receives signals? A) Axon B) Dendrites C) Synapse D) Myelin
B) Dendrites
What is the function of the myelin sheath?
To insulate axons and increase the speed of nerve impulse transmission.
True or False: The autonomic nervous system is part of the peripheral nervous system.
True
What are the two divisions of the autonomic nervous system?
Sympathetic and parasympathetic.
Fill in the blank: The _______ nervous system prepares the body for ‘fight or flight’ responses.
Sympathetic
Short Answer: What is a synapse?
A junction between two neurons where signals are transmitted.
Multiple Choice: Which neurotransmitter is primarily involved in mood regulation? A) Dopamine B) Serotonin C) Acetylcholine D) Norepinephrine
B) Serotonin
What is the role of the spinal cord?
To transmit signals between the brain and the rest of the body and to coordinate reflexes.
True or False: Reflex actions are processed by the brain.
False
What is the function of sensory neurons?
To carry information from sensory receptors to the central nervous system.
What do motor neurons do?
They transmit signals from the CNS to muscles and glands.
Fill in the blank: The _______ nervous system controls voluntary movements.
Somatic
What part of the brain is responsible for coordination and balance?
Cerebellum
Multiple Choice: Which lobe of the brain is responsible for processing visual information? A) Frontal B) Parietal C) Occipital D) Temporal
C) Occipital
True or False: The brain stem controls basic life functions such as breathing and heart rate.
True
What is the primary role of the thalamus?
To act as a relay station for sensory information.
Fill in the blank: The _______ lobe is involved in decision-making and problem-solving.
Frontal
What is neuroplasticity?
The ability of the nervous system to change its structure and function in response to experience.
