Neurology
What is an axon
the extension of a neuron that carries messages away from the cell body.
Guess the lobe!
Located at the front of the brain, this lobe is responsible for complex thinking, decision-making, problem-solving, planning, and controlling movement. It also plays a role in personality and emotional regulation.
Frontal Lobe

d. seeing; hearing
What is an action potential
A brief electrical charge that travels down the axon of a neuron is called the

Temporal
What is rem rebound
REM: Paradoxal
REM rebound is a phenomenon where, after being deprived of REM (Rapid Eye Movement) sleep, the body "rebounds" by spending more time in REM sleep the next time you sleep.
What is your vestibular system?
The vestibular system, located in the inner ear, helps us maintain balance, posture, and spatial orientation by sensing head movements and gravity.

b. hypothalamus.
c. motor cortex.
d. reticular formation.
c. motor cortex
What is a neurotransmitter
chemical messengers released into the spatial junctions between neurons
