Axons receive impulses and then pass them to the cell body.

Sensory neurons originate from the brain or spinal cord to the body parts.

Motor neurons exclusively connect sensory neurons within the spinal cord.

The central nervous system (CNS) consists of the brain and spinal cord.

Voluntary actions are actions controlled by the spinal cord.

Reflex actions are quick, automatic responses to a stimulus without brain involvement.

The nervous system solely controls voluntary movements like walking and writing, independent of involuntary processes.

Neurons transmit messages through electrical impulses, with dendrites receiving impulses and axons transmitting them away from the cell body.

The central nervous system (CNS) comprises the brain and spinal cord, with the peripheral nervous system (PNS) consisting of nerves linking the CNS to body organs.

The cerebrum, located at the back of the head, primarily coordinates muscular activity and maintains balance; damage to this area leads to impaired cognitive functions.

Reflex actions, controlled by the brain, are slower responses to stimuli, allowing for conscious decision-making before a reaction occurs.

Motor neurons carry impulses from the brain to sensory organs, enabling the perception of stimuli like touch and sound.

The brain stem, or medulla oblongata, controls voluntary actions like walking and writing, ensuring coordinated movement.

A nerve is composed of multiple neurons bundled together, each transmitting signals independently without interaction.

Spinal nerves emerge exclusively from the brain, transmitting signals to various body parts without involving the spinal cord.

Internal stimuli include environmental factors such as light and touch, triggering responses like moving away from heat.

Association neurons directly connect sensory organs to muscles, creating a shortcut for immediate reflex responses.

Increasing the surface area of the cerebrum is achieved through a smooth, uniform surface, maximizing neuron density.
