Neuroanatomy and Physiology

Synapses are the junctions between neurons where signals are transmitted.

Dendrites are the branched extensions of a neuron that receive signals from other neurons.

The axon hillock is the region of the neuron where electrical impulses are generated.

Myelin sheath insulates the axon, increases the speed of signal transmission, and protects the neuron from damage.

Glutamate is the primary excitatory neurotransmitter in the central nervous system.

The cerebellum is responsible for coordinating muscle movements, maintaining balance and equilibrium, and planning and executing voluntary movements.

The occipital lobe is responsible for processing visual information.

The hypothalamus regulates body temperature, controls hunger and thirst, and produces hormones.

The frontal lobe is responsible for higher-level cognitive functions such as reasoning, decision-making, and problem-solving.

The autonomic nervous system controls involuntary functions such as heart rate and digestion.

Neurons are not glial cells. Glial cells are non-neuronal cells that support and protect neurons.

The blood-brain barrier protects the brain from harmful substances in the blood, regulates the flow of nutrients and oxygen to the brain, and maintains the brain's electrical activity.

The temporal lobe is responsible for processing auditory information.

The hippocampus is involved in encoding new memories, storing long-term memories, and retrieving memories.

Glucose is not a neurotransmitter. Neurotransmitters are chemical messengers that transmit signals between neurons.
