Nervous System Flashcards
What controls the body’s functions and sends messages between the brain and the body?
Nervous system
What system includes the brain, spinal cord, and a complex network of nerves, sending messages back and forth between the brain and the body, and controlling all the body’s functions?
Nervous System
is a complex and vital part of the human body, responsible for various functions that allow organisms to perceive, process, and respond to the environment.
Nervous System
What are the basic functions of the Nervous System?
- Sensory Input
- Integration
- Motor Output
- Homeostasis
- Coordination
- Autonomic Functions
- Reflex Actions
Basic Functions
Which basic function of the nervous system involves gathering information from the environment and internal conditions?
Sensory input
Basic Functions
What function is responsible for processing and interpreting sensory information?
Integration
Basic Functions
Which function sends signals to muscles and glands for physical responses?
Motor output
Basic Functions
What function maintains internal stability by controlling physiological processes?
Homeostasis
Basic Functions
Which function coordinates activities among organs and body parts to ensure harmony?
Coordination
Basic Functions
What function regulates involuntary bodily functions through the autonomic nervous system?
Autonomic functions
Basic Functions
Which function is responsible for rapid and automatic responses to stimuli, often mediated by the spinal cord?
Reflex actions
Basic Functions
Examples include temperature regulation, blood pressure maintenance, and pH balance.
HOMEOSTASIS
Basic Functions
Responsible for voluntary movements and involuntary actions like heartbeat and digestion.
MOTOR OUTPUT
Basic Functions
Controlling processes like heart rate, respiratory rate, and digestion.
AUTONOMIC FUNCTIONS
Basic Functions
Often mediated by the spinal cord without direct involvement of the brain.
REFLEX ACTIONS
What are the HIGHER COGNITIVE FUNCTIONS?
- COGNITION
- EMOTION
- MEMORY
- CONSCIOUSNESS
- COMMUNICATIONS
- ADAPTATION
- LEARNING AND PLASTICITY
Higher Cognitive Functions
Which function involves higher mental processes such as thinking, reasoning, and problem-solving?
Cognition
Higher Cognitive Functions
What function plays a role in generating and processing emotions?
Emotion
Higher Cognitive Functions
Emotional responses are influenced by various __ and __.
brain structures and neurotransmitters
Higher Cognitive Functions
Which function is essential for storing and retrieving information?
Memory
Higher Cognitive Functions
What function contributes to the state of awareness and consciousness?
Consciousness
Higher Cognitive Functions
How do neurons communicate within the nervous system?
Through electrical impulses and chemical signals (neurotransmitters) – Communication.
Higher Cognitive Functions
What function enables organisms to adjust to changing environmental conditions?
Adaptation
Higher Cognitive Functions
Which function allows neural connections to reorganize based on experience?
Learning and plasticit
2 Divisions of Nervous System
- Central Nervous System
- Peripheral Nervous System
Central Nervous System consists of:
Brain and Spinal Cord
The 3 Main Parts of the Brain:
- Cerebrum
- Cerebellum
- Brain Stem
3 Main Parts of the Brain
Which part of the brain is responsible for learning, memory, interpretation, and personality?
Cerebrum
3 Main Parts of the Brain
Which part of the brain controls balance, movement, and coordination?
Cerebellum
3 Main Parts of the Brain
What part of the brain connects to the spinal cord and regulates autonomic functions such as respiration and blood pressure?
Brain Stem
3 Main Parts of the Brain
Which brain structure is composed of the midbrain, pons, and medulla oblongata?
Brain Stem
3 Main Parts of the Brain
Which part of the brain is involved in voluntary functions such as learning and personality?
Cerebrum
3 Main Parts of the Brain
The __ is located in the back of the brain just below the cerebrum.
Cerebellum
The Spinal Cord
The spinal cord extends from the __ and down the back.
medulla oblongata
The Spinal Cord
Which structure protects the spinal cord?
vertebral column
What system is composed of the brain and spinal cord?
The central nervous system (CNS)
What is responsible for transmitting information between the body organs and the brain?
The nerves in the spinal cord
Which nervous system acts as a communication network between the CNS and the rest of the body?
The Peripheral Nervous System (PNS)
