Which of the following best describes the primary function of neurons in the brain?

• To provide structural support for the brain

• To receive, process, and transmit electrochemical signals

• To produce cerebrospinal fluid

• To regulate blood flow to brain tissues

In the diagram of a typical neuron, which structure receives signals from other neurons?

• Axon Terminals

• Myelin Sheath

• Dendrites

• Soma

What is the key difference between rate coding and temporal coding in neural communication?

• Rate coding involves the frequency of action potentials, while temporal coding involves the precise timing of action potentials

• Rate coding is used only in the peripheral nervous system, while temporal coding is used only in the central nervous system

• Rate coding requires multiple neurons, while temporal coding can be achieved with a single neuron

• Rate coding is a newer evolutionary adaptation compared to temporal coding

Which plane divides the brain into anterior (front) and posterior (back) portions?

• Saggital

• Coronal

• Horizontal

• Transverse

Which statement best describes the contralateral organization of the brain?

• The left hemisphere primarily controls sensory and motor functions on the left side of the body

• The right hemisphere processes information from both sides of the body equally

• The left hemisphere primarily controls sensory and motor functions on the right side of the body

• The corpus callosum prevents any crossover of function between hemispheres

Which region of the brain is primarily responsible for coordinating movement and maintaining balance?

• Frontal lobe

• Cerebellum

• Temporal lobe

• Occipital lobe

Synapses that are ____________ cause a neuron to fire whereas ____________ synapses reduce the likelihood that a neuron will fire.

• excitatory; inhibitory
• synaptic; terminal
• postsynaptic; presynaptic
• dendritic; axon

Terminal Buttons are found at the ends of _____________.

• Dendrites

• Axons

• Glial Cells

• Cell Bodies
