Terms of Movement
What are the 6 movements of the spine? Doesn’t have to be technical terms.
What is flexion, extension, lateral flexion R+L, and rotation R+L?
What sensory receptor category senses internal environment?
What is interoreceptors?
What is the difference between fascia and connective tissue?
fascia is a sub category of connective tissue that is sheet like
Connective tissue is a broad category encompassing bone, cartilage, blood, lymph, and fascia
What is tightness?
Tightness is sensation, not measurable or correlated with ROM or dysfunction
What type of tissue is bone?
What is connective tissue?
What is the main movement in the shoulder joint when you reach for something high?
What is flexion?
What is the role of the sympathetic nervous system?
What is to mobilize/activate?
Fascia is made of these three things
What is fibers, gels, and cells?
Fibers- collagen, elastin, reticular
Gels- fluid part of ECM
Cells- fasciacytes, fibroblasts
Name 3 areas of your body affected by shallow breath
What is your neck, shoulders, ribs, psoas, abdominal muscles, organs, back, etc.?
How many vertebrae are in your thoracic spine?
What is 12?
What 3 movements are present at the hip joint in a seated butterfly position?
What is flexion, lateral rotation, and abduction?
This runs through your face, throat, and diaphragm and is 75% of the parasympathetic NS
What is the vagus nerve?
Explain how fascia has a different form throughout the body, and why
Form follows function, fascia is more irregular in areas that need to move a lot of ways, regular in areas where force is distributed linearly, loose fascia allows movement, dense is for stability
How does your diaphragm create your inhale?
What is it draws down, increasing the volume of your thoracic cavity?
In a standing forward fold, your spine is under what stress?
What is tensile stress?
What 6 movements are possible at the shoulder joint?
What is flexion, extension, adduction, abduction, medial rotation, and lateral rotation? (Circumduction encompasses them all)
Describe the stretch reflex
prevents you from going too far, too quickly into a stretch
Describe viscoelasticity and how different movement affects movement because of it
This property describes fascia's ability to stretch and recoil- with slow sustained load it deforms/stretches, with quick bouncy movement it resists for energy efficient movement and shock absorption
Name 3 load parameters that affect how much load your tissues take on
Frequency, Duration, External/Internal Force(Magnitude), Velocity, Acceleration, Direction
Is your body a compression or a tension structure? Explain.
What is both? - bones are suspended in tensile connective tissue like a tensegrity model
Flexion is generally the anterior surfaces of the body shortening except for what two exceptions?
What is the knee joint and the toes?
List all the branches/categories of the nervous system
Central
Peripheral - Autonomic - Parasympathetic + Sympathetic
Somatic - Afferent + Efferent nerves
Describe stiffness and compliance and how it affects movement
stiffness - fascia takes more load to deform, and recoils quickly - useful for quick bursts of power
compliance - fascia deforms easily under lighter loads, but takes time to recover - useful for movements that require bigger range of motion
Do muscles become weak or overly lengthened from stretching? Explain
Muscles become weak from being under loaded, stretching doesn't always create enough load, so it may become aggravating for some. Stretching doesn’t create length in the tissues, we adapt to explore a length we are already capable of reaching
Describe skeletal variation, and how our bones fit together can change
Skeletal variation shows how range of motion can be variable between individuals purely based on the structure of the bones and how they fit together. However, bones are suspended in tissue, so the balance of tension through the system can affect how the bones are in relation to each other
