Brain Lobes
This lobe helps you hear sounds, and processes both smell and memory, which is why certain scents remind you of past events.
Answer: What is the temporal lobe?
These are the two halves of your brain.
Answer: What are the left and right hemispheres?
The nervous system is divided into 2 main parts, what are they?
What are the 2 main parts of the CNS?
CNS Central Nervous System
PNS Peripheral Nervous System
CNS: Brain and Spinal Cord
The neurons that carry messages to the brain when you feel something, you have about 10 million of.
What are sensory neurons?
The system that sends messages to the outer edges of your body.
What is the Peripheral Nervous System?
This lobe at the back of your brain helps you see things.
Answer: What is the occipital lobe?
This hemisphere is strongest in math and logical thinking.
Answer: What is the left hemisphere?
This part of the brain controls breathing and heartbeat and blood pressure automatically.
Answer: What is the brainstem?
The neurons that send movement commands from your brain to your body, you have about 500,000 of.
What are motor neurons?
The direction signals always travel in a neuron.
What is: dendrite → cell body → axon → terminals
This lobe helps you feel touch, temperature, and pressure.
Answer: What is the parietal lobe?
This hemisphere is stronger in art, and creativity.
Answer: What is the right hemisphere?
This part of the brain helps you move smoothly—like dancing or swinging, and helps you balance so you don’t fall over.
Answer: What is the cerebellum?
The pathway used when your brain sends the message to scream after you hurt your finger.
what are motor neurons?
The chemicals that carry messages across the tiny gap between neurons.
The tiny space between neurons that acts like a gatekeeper.
→ What are neurotransmitters?
→ What is the synapse?
This lobe is where your thoughts and decisions are made.
Answer: What is the frontal lobe?
These areas of the cerebrum include the frontal, parietal, occipital, and temporal regions.
Answer: What are the lobes?
This term describes the brain’s ability to strengthen, weaken, or create new connections between neurons based on experiences, practice, and learning.
What is Neuroplasticity?
These protective bones form a column that safely encloses the spinal cord.
Made of sensory and motor neurons, these structures act like telephone cables connecting the body to the brain.
the spinal column
Nerves
How many nerves come directly from the brain "Cranial nerves"?
How many branch off the spinal cord?
How many cranial nerves on one side of the body?
How many Spinal nerves on one side of the body?
There are 24 nerves that come directly from the brain.
There are 62 nerves that branch off the spinal cord.
12 cranial nerves
31 spinal nerves
What are the 3 basic functions of the nervous system?
1. receiving sensory input
2. integrating received information
3. generating a motor response
Scientists use these special images of the brain, taken during activities, to discover which tasks activate which areas.
Answer: What are brain scans?
This part of the brain is where most nerve tracts from the cerebrum cross over to control the opposite side of the body. It also sorts information and sends signals between the brain and spinal cord.
Answer: What is the brainstem?
These vertebrae, labeled C1 to C8, are found in the neck.
Named after the chest region, these vertebrae are labeled T1 to T12.
These nerves are numbered from L1 through L5.
These vertebrae and their nerves, labeled S1 to S5, are named after the sacral bone.
This small tailbone structure gives its name to the final pair of spinal nerves.
cervical vertebrae-neck
thoracic-chest
lumbar-lowest back
sacral
coccyx
The part of the neuron that collects information like tiny branches.
The part of the neuron that contains the nucleus.
The long pathway that carries signals away from the neuron’s cell body.
The fatty coating that speeds up nerve signals.
The organelles that give neurons their high energy supply.
→ What are dendrites?
→ What is the cell body?
→ What is the axon?
→ What is the myelin sheath?
→ What are mitochondria?
