Neurons
Specialized cells that transmit nerve impulses; consist of a cell body or soma, dendrites, and axon.
What are Neurons?
Forms membranes around nerve tissue
What is Ependymal cells?
Which lobe of the brain is responsible for body movement of the right side of the body?
What is the left hemisphere motor cortex?
What is resting potential?
Branch-like structures that receive signals from other neurons
What are dendrites?
Immune functions, digest debris, kill bad bacteria
What are Microglial Cells?
Decreases heart rate and promotes digestion (rest and digest response).
What is activation of the parasympathetic nervous system?
What lobe of the brain is responsible for the left eye?
What is the right hemisphere occipital lobe?
What is nerve impulse?
Insulating layer around the axon made by Schwann cells.
What is Myelin Sheath?
Makes myelin sheath that provides insulation to the axon. Attached to dendrite and soma to cover axon (in central nervous system)
What are Oligodendrocytes?
Components of the autonomic nervous system
What are Sympathetic and Parasympathetic?
What lobe and hemisphere is known for being the creative side?
What is the right frontal lobe?
- outside --> + inside
Part of neuron that transmits signals away from the soma to other neurons or muscles.
What is Axon?
Connects blood vessels to neurons
What are Astrocytes?
Motor neurons, sends signals from the brain to skeletal muscles, voluntary
What is somatic nervous system?
What is responsible for balance and muscle memory?
What is the cerebellum?
What are the 2 things that can open and close during a nerve impulse?
What are voltage gated sodium channels and potassium channels?
Gaps in the myelin sheath that the signals up to.
What is Nodes of Ranvier?
Makes myelin sheath that surround neurons in the peripheral nervous system
What is Schwann cells?
Efferent = exits the brain, sends messages from brain to the muscles and glands, motor neurons for motor output
What is the motor division?
What part of the brain stem is responsible for heartbeat, breathing, and blood pressure
What is the medulla oblongata?
Major ions (elements) involved in resting potential
What are Sodium (Na+) and Potassium (K+)
