the brain and neuron cell Flashcards
What is the function of the frontal lobe?
Personality, thinking, planning, problem solving
The frontal lobe is associated with higher cognitive functions.
What does the temporal lobe control?
Speech and hearing
The temporal lobe plays a key role in processing auditory information.
What is the role of the brain stem?
Controls all the automatic functions
The brain stem regulates vital functions such as heart rate and breathing.
What is the function of the spinal cord?
Links the brain to the rest of the body
The spinal cord serves as a major pathway for information traveling between the brain and body.
What does the cerebellum control?
Movement, balance, and muscles
The cerebellum is crucial for coordinating voluntary movements.
What is the function of the occipital lobe?
Controls memory, sight, and smell
The occipital lobe is primarily responsible for visual processing.
What does the parietal lobe control?
Movement, sensations (pain, taste, touch, etc.), speed, and writing
The parietal lobe integrates sensory information from various modalities.
What is the nucleus in a neuron?
Inside the soma, controls cell’s activities
The nucleus contains the genetic material and regulates cell function.
What is the function of the soma (cell body)?
Contains nucleus, processes signals
The soma is essential for maintaining the health of the neuron.
What are dendrites?
Tree-like branches that receive signals
Dendrites play a key role in receiving input from other neurons.
What is the axon?
A long thread that transmits electrical impulses
Axons carry signals away from the soma to other neurons or muscles.
What are myelin sheaths?
Fatty coverings that speed up signal transmission
Myelin sheaths insulate axons and enhance the speed of electrical impulses.
What is the axon terminal?
Branches at the end that release signals to other neurons
Axon terminals contain neurotransmitters that facilitate communication between neurons.
