Nervous System Flashcards
To learn about the anatomy and functions of the different parts of the nervous system.
What is responsible for transmitting information across the body?
The nervous system.
What does the nervous system control?
Vital functions such as breathing and heartbeat.
What is the sensory function of the nervous system?
It detects internal and external changes called stimuli.
What does the integrative function of the nervous system perform?
Interpretation of sensory input.
What does the motor function send commands to?
Muscles and glands for responses.
What is the basic functional unit of the nervous system?
The neuron.
What does each neuron contain?
A soma and projecting structures called neurites.
What does the central nervous system consist of?
The brain and spinal cord.
What does the peripheral nervous system connect?
The spinal cord to the rest of the body.
What does the cerebrum regulate?
Emotions, memory, and voluntary movement.
What does the frontal lobe control?
Reasoning, speech, and voluntary movement.
What does the parietal lobe process?
Touch and spatial awareness.
What does the temporal lobe interpret?
Auditory information and forms memory.
What is the brain’s visual processing center?
The occipital lobe.
What connects the left and right cerebral hemispheres?
The corpus callosum.
What does the thalamus relay?
All sensory signals except smell.
What is the amygdala involved in?
Fear processing and emotional response.
What does the hypothalamus regulate?
Body temperature and controls the pituitary gland.
What do the colliculi in the midbrain process?
Visual and auditory input.
What does the pons help regulate?
Sleep and motor control.
What does the medulla oblongata control?
Involuntary functions like heartbeat.
What does the cerebellum coordinate?
Balance and fine movement.
What does the somatic nervous system control?
Voluntary muscle activity.
What does the autonomic nervous system manage?
Involuntary body functions.
