Nerve Cells
What are nerve cells?
Nerve cells, also known as neurons, are part of a huge system called the nervous system.
Sensory and motor neurons are connected by association neurons.
Nerve cells help transmit messages to from one part of the body to another. These messages are carried through nerve impulses.
Sensory neurons detects stimuli, such as light, heat, or chemicals that are from both the inside and outside of the body. It lets you smell and feel too.
Functions
Function of Nerve Cells
Motor neurons distribute instructions to muscles and glands from the nervous system.
Nerve cells are functionally classified into three types; sensory neurons, motor neurons, and association neurons.
In order to create a nerve impulse, neurons must be excited. A chemical called a neurotransmitter is often released by other neurons to get the job done.
The Brain
The Brain
The brain is part of the nervous system in our skull.
What happens when we learn new things?
When we learn new things, our brain creates more connections and neurons. It can also make neural pathways weaker and stronger. This change is called "plasticity". The brain becomes more "plastic" as we learn. Waves of dopamine can be released, which makes us want to learn more because we feel the rush of excitement. The brain can actually grow larger as we practice new hobbies or learn a new language.
When we don't learn anything new, our brain slows down and it becomes harder to quickly adapt to new information. Not only that, but when we stop learning new things, we lose our confidence and we become less relevant. We might not be able to answer questions without doubting ourselves on whether we answered correctly or not.

Importance of Learning
Learning Importance
Learning keeps our health in check. Studies show that people who don't learn things very often are twice as likely of getting a heart disease than people who actively learn. Learning new things also helps us easily think of new ideas and it's definitely a great confidence booster!
