Animal Nervous System Flashcards
Flashcard 1:
What is the nervous system?
The nervous system is a complex network of nerves and cells that transmit signals between different parts of the body to coordinate its actions.
Flashcard 2:
Q: What are the two main parts of the human nervous system?
A: The two main parts are the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).
Flashcard 3
Q: What does the Central Nervous System (CNS) consist of?
A: The CNS consists of the brain and the spinal cord.
Flashcard 4
Q: What are neurons?
A: Neurons are specialized cells that transmit nerve impulses throughout the body.
Flashcard 5
Q: What are the three types of neurons?
A: The three types are sensory neurons, motor neurons, and interneurons.
Flashcard 6
Q: What is the function of sensory neurons?
A: Sensory neurons transmit signals from sensory receptors to the Central Nervous System.
Flashcard 7
Q: What is a synapse?
A: A synapse is a junction between two neurons where nerve impulses are transmitted.
Flashcard 8
Q: What role does the brain play in the nervous system?
A: The brain acts as the control center, processing and interpreting sensory information and directing responses.
Flashcard 9
Q: What is a reflex action?
A: A reflex action is an automatic and quick response to a stimulus that does not involve conscious thought.
Flashcard 10
Q: How does the Peripheral Nervous System (PNS) function?
A: The PNS connects the Central Nervous System to the limbs and organs, facilitating communication between the brain and the rest of the body.
