Central Nervous System
What is the CNS (central nervous system)?
The CNS is like your body’s command center-taking in information, making decisions and sending out orders that let you sense, think and survive
What is sciatica?
A condition characterized by pain that radiates from the lower back through the buttocks and down one or both legs. It occurs when the sciatic nerve, the largest nerve in the body, becomes compressed or irritated.
True or False: The glute medius keeps our hips level when we walk.
True: If it’s weak, the knee caves in and creates strain and knee pain.
What is a subluxation?
A subluxation is a partial dislocation or misalignment of a joint. It occurs when the bones in a joint are not properly positioned or move abnormally.
How does an adjustment impact the Central Nervous system?
By removing nerve interference, it allows the nervous system to function more effectively.
What are the 5 Key functions of the CNS (central nervous system)?
1. Process information ex) hearing your name
2. Controls Movement ex) Voluntary (walking) Involuntary (reflex)
3. Regulates automatic body functions ex) breathing, digestion
4. Enables Thinking and Emotions ex) memory, learning, emotions
5. Coordinates Reflexes ex) pulling hand away from hot stove
What is neuropathy?
Neuropathy is a condition that damages the nerves outside the brain and spinal cord (peripheral nervous system). It can affect any part of the body, but is most common in the hands, feet, legs, and arms.
True or False: The rotator cuff stabilizes the shoulder.
True: If weak, the shoulder becomes unstable and gets pinched.
What causes a subluxation?
Subluxations can be caused by various factors, including: Trauma (e.g., falls, accidents), Repetitive motions, Poor posture, Stress, and Muscle imbalances.
How do adjustments improve mobility?
Adjustments improve the range of motion and flexibility in stiff joints.
What is housed in the spine?
The spinal cord is a long, thin, and fragile structure that runs through the spinal canal, essentially acting as a pathway for messages between the brain and the rest of the body.
How are they similar & different?
Both sciatica and neuropathy can cause pain, tingling, and numbness. They can also be caused by a lack of circulation, whether on your sciatic nerve or elsewhere in your body.
You usually feel more pain sitting with sciatica - it can flare up in the morning and may change as you move around. But with neuropathy, the pain is more consistent, and you may have more sensitivity to touch, like from socks and shoes touching your feet. Sciatica feels deep in the hip and can ease up as you move about your day, and it also typically presents one-sided (only one side of your body is affected).
True or False: Erector spinae and multifidi keep us upright.
True:
The core is the foundation — if it’s weak, the spine compensates.
Erector spinae and multifidi keep us upright.
The glutes hold the pelvis in position, preventing extra stress on the low back and knees. Traps/rhomboids pull shoulders back for an open chest.
What are 3 common symptoms of a subluxation?
Common symptoms include: Pain, Limited range of motion, Swelling, Numbness or tingling, and Instability
What is Chiropractic BioPhysics® (CBP)?
It uses a scientific, evidence-based approach to corrective chiropractic care.
At its core, CBP aims to do more than provide temporary relief from symptoms. Instead, it focuses on addressing the root cause of spinal issues by:
What sets CBP apart is its emphasis on long-term correction rather than short-term symptom management. This approach provides immediate pain relief and works towards preventing future issues.
How does a spinal misalignment (SUBLUXATION) affect the nervous system?
Subluxations interfere with nerve signals, leading to pain, dysfunction and reduced mobility
How to adjustments help with both?
Adjustments Improving Blood Flow and Oxygenation. Chiropractic adjustments and soft tissue therapies help increase blood flow to the affected areas, improving nerve health and reducing symptoms like numbness and tingling.
Which muscle prevents the knee from caving in during a squat?
Glute medius
True or False: Being adjusted every 7-10 days is the best way to treat subluxations within the spine for maintenance care.
True
Why is Corrective Chiropractic care (CBP) different than other types of Chiropractic care?
The scientific basis of CBP is what truly sets it apart from traditional chiropractic techniques. Here are some fundamental principles that form the foundation of CBP:
CBP practitioners use these principles to create highly individualized treatment plans. CBP combines chiropractic adjustments with exercises and traction. Its goal is to reshape the spine over time. This should improve posture and health.
The spine is made of 33 bones in 4 regions. What are the regions of the spine and how many bones are in each region?
Cervical spine: 7 vertebrae (C1-C7)
Thoracic spine: 12 vertebrae (T1-T12)
Lumbar spine: 5 vertebrae (L1-L5)
Sacrum and coccyx: 9 fused vertebrae (S1-S5 and Co1-Co4)
How does laser therapy help with both?
Laser Therapy: Laser devices emit painless beams of light at specific wavelengths. When this light reaches injured tissue, it sparks a chain of cellular events:
Energizes cells. Photons boost mitochondrial activity, creating more ATP—the “fuel” nerves need for repair.
Calms inflammation. Light triggers natural anti-inflammatory chemicals, easing the chemical irritation that often intensifies neuropathic pain.
Improves micro-circulation. Blood vessels dilate, delivering extra oxygen and nutrients while sweeping away waste products that can slow healing.
Supports myelin and collagen production. Healthier protective sheaths and connective tissue help nerve signals travel smoothly.
Which tight muscle group in the lower leg can alter walking mechanics and hurt the knee?
Calves
What is the difference between subluxation and dislocation?
Subluxation:
Dislocation:
What are 3 reasons why a patient would do Corrective Chiropractic care?
